What is the Best Pesticide for Tomato Plants?

Picture this: Sarah, a passionate home gardener in Nebraska, has spent months nurturing her tomato plants. They’re finally loaded with green fruit, promising a bounty of juicy, ripe tomatoes. Then, seemingly overnight, she notices it – curling leaves, sticky residue, tiny green critters clinging to the undersides, and some leaves practically skeletonized. Her heart sinks. What’s happening? And more importantly, what can she do? She frantically searches online, typing “What is the best pesticide for tomato plants?” into the search bar, hoping for a magic bullet.

To quickly and precisely answer that burning question, there isn’t one single “best” pesticide for tomato plants. Instead, the most effective approach involves understanding the specific pest you’re dealing with, embracing an Integrated Pest Management (IPM) strategy, and choosing the least toxic yet most effective treatment option for your particular situation. Often, the “best” solution isn’t a pesticide at all, but rather a combination of preventative measures and biological controls. When pesticides are necessary, the “best” choice is the one that targets your specific pest, minimizes harm to beneficial insects and the environment, and is safe for you and your family.

My own experience, after years of wrestling with everything from insidious spider mites to voracious hornworms in my backyard patch, has taught me that gardening is less about finding a quick fix and more about cultivating a deep understanding of your plants and their ecosystem. It’s a journey of observation, patience, and making informed choices. Let’s dig into what really works to keep your tomato plants thriving and productive.

Understanding Your Foe: Common Tomato Pests

Before you even think about reaching for a spray bottle, you’ve got to play detective. Identifying the specific pest is paramount, as different pests respond to different treatments. Here are some of the usual suspects that love to make a meal out of your beloved tomato plants:

Aphids

• Identification: Small, pear-shaped insects, often green, black, yellow, or pink. They cluster on new growth, stems, and the undersides of leaves.
• Damage: They suck sap, causing leaves to curl, yellow, and distort. They also excrete a sticky substance called honeydew, which can lead to sooty mold growth.
• Life Cycle: They reproduce rapidly, often without mating, leading to quick infestations.

Tomato Hornworms

• Identification: Large, green caterpillars, often several inches long, with a distinctive “horn” at their rear end. They blend remarkably well with tomato foliage.
• Damage: These guys are voracious eaters, capable of defoliating an entire plant in a few days. Look for large areas of missing leaves and their tell-tale droppings (frass) on the leaves below.
• Life Cycle: They emerge from the soil as moths, lay eggs on leaves, and the larvae (caterpillars) cause the damage.

Whiteflies

• Identification: Tiny, white, moth-like insects that flutter up in a cloud when disturbed. They’re usually found on the undersides of leaves.
• Damage: Like aphids, they suck sap and excrete honeydew, leading to weakened plants and sooty mold.
• Life Cycle: They have a short life cycle and reproduce quickly, making them persistent pests.

Spider Mites

• Identification: Almost invisible to the naked eye, these tiny arachnids create fine webbing on plants, especially on the undersides of leaves and in leaf axils.
• Damage: They cause stippling (tiny yellow or white dots) on leaves as they feed, eventually leading to bronzing, yellowing, and leaf drop. They thrive in hot, dry conditions.
• Life Cycle: They reproduce extremely quickly, going from egg to adult in a matter of days.

Cutworms

• Identification: Grayish-brown caterpillars that curl into a “C” shape when disturbed. They’re primarily nocturnal.
• Damage: They chew through young plant stems at soil level, often severing them completely overnight.
• Life Cycle: Larvae overwinter in the soil, emerging in spring to feed on tender seedlings.

Stink Bugs and Leaf-footed Bugs

• Identification: Stink bugs are shield-shaped, often green or brown. Leaf-footed bugs are brown, with distinctive flattened “leaf-like” sections on their hind legs.
• Damage: They use their piercing-sucking mouthparts to feed on fruits, causing dimples, discolored spots, and internal corky tissue, making the fruit unmarketable or unappetizing.
• Life Cycle: Adults overwinter and emerge to lay eggs, with multiple generations possible in warmer climates.

Flea Beetles

• Identification: Small, shiny beetles, often black or metallic, that jump like fleas when disturbed.
• Damage: They chew small, round holes in leaves, giving them a “shotgun” appearance. Severe infestations can stunt young plants.
• Life Cycle: Adults feed on foliage, lay eggs in the soil, and larvae feed on roots.

The IPM Philosophy: Your Best Defense

My friends, let me tell you, if there’s one thing that will truly save your sanity and your tomato harvest, it’s embracing an Integrated Pest Management (IPM) approach. This isn’t just a fancy term; it’s a smart, holistic strategy that minimizes risks to people, pets, and the environment while effectively managing pests.

What is IPM?

IPM is essentially a common-sense approach to pest control. It focuses on long-term prevention of pests and their damage through a combination of techniques, including biological control, habitat manipulation, modification of cultural practices, and the use of resistant varieties. Pesticides are used only when necessary, and with a preference for products that are the least harmful to human health and the environment.

Why IPM is Crucial for Tomatoes

Tomatoes are often a target for a wide array of pests. Relying solely on chemical pesticides can lead to several problems:

• Pest Resistance: Pests can develop resistance to frequently used chemicals, rendering them ineffective down the road.
• Harm to Beneficials: Broad-spectrum pesticides kill not only the bad guys but also the good guys – the beneficial insects that naturally keep pests in check. This can create a vacuum, allowing new pest outbreaks to occur without natural predators.
• Environmental Impact: Runoff can contaminate soil and water, harming local ecosystems.
• Health Concerns: Residues on edible crops can pose risks to you and your family.

IPM, on the other hand, encourages a balanced ecosystem where your tomatoes can thrive with minimal intervention.

Core Components of IPM

1. Monitoring: Regular inspection of your plants is key. Early detection means smaller problems and easier solutions. I make it a ritual to walk through my garden every morning with a cup of coffee, just looking for anything out of place.
2. Prevention: This is your first and best line of defense. Healthy plants are more resilient, and good cultural practices can stop many pest issues before they start.
3. Cultural Controls: These are the practices you employ to make your garden less appealing to pests.
4. Biological Controls: Unleashing nature’s warriors – beneficial insects and microorganisms – to fight your battles.
5. Chemical Controls (as a last resort): When other methods aren’t enough, judicious use of appropriate pesticides.

Preventative Measures and Cultural Controls (Your First Line of Defense)

Before you ever even consider a spray, let’s talk about the bedrock of a healthy tomato patch. These are the steps I take in my own garden that make a world of difference.

• Healthy Soil and Proper Watering: Strong, vigorous plants are less susceptible to pest attacks. Provide well-draining, nutrient-rich soil. Water deeply and consistently at the base of the plant to avoid stressing the foliage and to prevent fungal issues that can weaken plants and make them more vulnerable.
• Good Air Circulation: Proper spacing between plants helps air move freely, reducing humidity and making it less hospitable for many pests and diseases, especially spider mites and whiteflies. Pruning lower leaves and suckers also helps.
• Crop Rotation: Don’t plant tomatoes (or any other solanaceous crops like peppers, eggplants, or potatoes) in the same spot year after year. This breaks the life cycle of soil-borne pests and diseases that might be hanging around.
• Resistant Varieties: When buying seeds or starts, look for varieties labeled “VFN” (Verticillium, Fusarium, Nematode) or other disease/pest resistance codes. While not perfect against all pests, it’s a great head start.
• Weed Control: Weeds aren’t just competition for nutrients; they can harbor pests. Keeping your garden beds clean reduces hiding places for many undesirables.
• Pruning: Removing yellowing, diseased, or lower leaves (especially those touching the ground) improves air circulation and can eliminate hiding spots for pests. Just don’t go overboard and remove too much foliage, as the leaves are essential for photosynthesis and protecting ripening fruit from sunscald.
• Physical Barriers: For young seedlings susceptible to cutworms, a simple cardboard collar around the stem at soil level can save them. Floating row covers can protect young plants from flea beetles and early season aphids, just remember to remove them when flowers appear for pollination.
• Sanitation: Clean up plant debris at the end of the season. Many pests and their eggs can overwinter in dead leaves and stems, ready to re-emerge next spring.

Biological Controls: Nature’s Own Pest Patrol

This is where the magic really happens for me. Encouraging beneficial insects is like hiring a tiny, tireless security force for your garden. It’s a truly organic and sustainable way to keep pest populations in check.

• Beneficial Insects:
  • Ladybugs (Lady Beetles): Both adult and larval ladybugs are voracious eaters of aphids, spider mites, and other soft-bodied insects.
  • Lacewings: The larvae of green lacewings are often called “aphid lions” for good reason; they devour aphids, whiteflies, and other small pests.
  • Parasitic Wasps: These tiny wasps lay their eggs inside or on pests like aphids or hornworms, with the developing wasp larvae consuming the host from the inside out. Don’t worry, they’re not interested in stinging you!
  • Syrphid Flies (Hoverflies): Their larvae are also excellent aphid predators.
• Encouraging Biodiversity: Plant a diverse array of flowers and herbs among your tomatoes. Many beneficial insects are attracted to small-flowered plants like dill, fennel, cilantro, cosmos, and sweet alyssum, which provide nectar and pollen. Creating a habitat for them means they’ll stick around.
• Introduction of Beneficials: You can purchase beneficial insects online or from garden centers. Release them in the evening when temperatures are cooler and they’re less likely to fly away immediately. Make sure your garden isn’t contaminated with broad-spectrum pesticides first, or you’ll just be feeding them to the chemicals.

When Pesticides Become Necessary: A Closer Look

Sometimes, despite your best efforts with IPM, a pest problem just gets out of hand. Maybe you missed an early infestation, or an especially aggressive pest population has moved in. This is when pesticides might be needed, but always as a last resort and with careful consideration.

Decision-Making Checklist: When to Consider Pesticides

Before you spray, ask yourself these questions:

1. Is the pest correctly identified? (Crucial for choosing the right product.)
2. Is the infestation severe enough to warrant intervention? (Are there a few bugs, or is the plant truly suffering?)
3. Have I tried all non-chemical and biological options? (Hand-picking, water sprays, attracting beneficials.)
4. Are there beneficial insects present that I might harm? (Check for ladybugs, lacewing larvae, etc.)
5. What is the harvest stage of my tomatoes? (Consider “days to harvest” on product labels.)
6. Do I understand the pesticide label completely? (This is non-negotiable!)

Types of Pesticides for Tomato Plants

Organic/Natural Options

These options are generally considered safer for the environment and beneficial insects, but “organic” doesn’t mean “harmless.” Always use them responsibly.

• Neem Oil:
  • How it works: Derived from the neem tree, it acts as an anti-feedant, growth regulator, and repellent. It disrupts the life cycle of many insects (aphids, whiteflies, spider mites, hornworms in early stages).
  • Application: Mix with water according to label instructions and spray thoroughly, covering all leaf surfaces, especially undersides. Reapply every 7-10 days if needed.
  • Pros: Low toxicity to mammals, birds, and most beneficial insects once dry. Effective on a broad range of pests. Safe for use up to day of harvest.
  • Cons: Can harm beneficials if sprayed directly. Best applied in the evening to allow it to dry before bees are active. Can be less effective on very heavy infestations.
• Insecticidal Soaps:
  • How it works: These are specialized soaps that disrupt the cell membranes of soft-bodied insects, causing them to dehydrate and die. They are contact-only, meaning they must directly hit the pest to be effective.
  • Application: Mix with water and spray thoroughly, ensuring direct contact with pests like aphids, whiteflies, and spider mites.
  • Pros: Very low toxicity, minimal residue, breaks down quickly. Safe for use up to day of harvest.
  • Cons: Only effective on direct contact. No residual effect, so repeat applications are often necessary. Can cause leaf burn if applied in direct sun or high temperatures.
• Horticultural Oils (e.g., dormant oil, summer oil):
  • How it works: These highly refined petroleum or vegetable oils smother insects (eggs, larvae, adults) by blocking their breathing pores.
  • Application: Mix with water and apply thoroughly. “Summer oils” are lighter and can be used on foliage during the growing season.
  • Pros: Effective on aphids, whiteflies, spider mites, and scale. Relatively safe for beneficials once dry.
  • Cons: Can cause phytotoxicity (plant damage) if applied when temperatures are too high or if the plant is stressed. Must achieve thorough coverage.
• Bacillus thuringiensis (Bt):
  • How it works: Bt is a naturally occurring bacterium that produces toxins specifically harmful to certain insect larvae when ingested. The Bt ‘kurstaki’ strain (Bt-k) is highly effective against caterpillars like tomato hornworms.
  • Application: Mix and spray on foliage where caterpillars are feeding.
  • Pros: Extremely specific, only affecting susceptible caterpillars. Harmless to humans, pets, beneficial insects, and other wildlife. Safe for use up to day of harvest.
  • Cons: Only works if ingested, so it won’t affect sucking insects. Breaks down in sunlight, so reapplication might be needed after a few days or after rain.
• Pyrethrin (natural):
  • How it works: Derived from chrysanthemum flowers, natural pyrethrin is a fast-acting contact insecticide that disrupts the nervous system of many insects (aphids, whiteflies, flea beetles).
  • Application: Spray directly onto pests.
  • Pros: Fast knockdown, breaks down relatively quickly in sunlight.
  • Cons: Can be harmful to beneficial insects (including bees) if sprayed directly. Use with extreme caution. Not suitable for regular use in an IPM strategy focused on preserving beneficials.
• Diatomaceous Earth (DE):
  • How it works: Food-grade DE is a finely ground powder made from fossilized diatoms. On a microscopic level, it’s very sharp and abrasive. When insects crawl over it, it scratches their exoskeletons, causing them to dehydrate and die.
  • Application: Dust it lightly on plants and around the base. Reapply after rain.
  • Pros: Mechanical action means pests can’t develop resistance. Effective against slugs, snails, cutworms, flea beetles, and some crawling insects.
  • Cons: Can be irritating to eyes and lungs (wear a mask). Must be dry to be effective. Can also harm beneficial crawling insects, so use sparingly and precisely.

Synthetic/Conventional Options (Use with Caution)

In extreme cases, or for certain persistent pests, a synthetic pesticide might be considered. However, the risks to beneficials and the environment are generally higher, and adherence to label instructions is absolutely critical.

• Why sometimes necessary: For widespread, uncontrollable infestations where organic methods have failed, and the crop is at severe risk. For example, a heavy infestation of stink bugs might require stronger intervention to salvage fruit.
• Pyrethroids (synthetic versions, e.g., Permethrin, Cyfluthrin):
  • How they work: These are synthetic versions of natural pyrethrin, often more stable and longer-lasting. They act as broad-spectrum neurotoxins.
  • Pros: Highly effective on a wide range of insects, fast-acting.
  • Cons: Highly toxic to beneficial insects, fish, and aquatic life. Can persist in the environment longer. Requires strict adherence to safety precautions and harvest intervals. I rarely, if ever, recommend these for home vegetable gardens unless absolutely necessary and with extreme care.
• Carbaryl (Sevin):
  • How it works: A broad-spectrum carbamate insecticide that affects the nervous system.
  • Pros: Effective against many chewing insects like flea beetles, hornworms, and some stink bugs.
  • Cons: Highly toxic to bees and many other beneficial insects. Requires significant caution and adherence to strict pre-harvest intervals. I typically avoid this one in my home garden because of the potential collateral damage.
• Malathion:
  • How it works: An organophosphate insecticide that is a broad-spectrum nerve agent.
  • Pros: Can be effective against aphids, spider mites, and whiteflies.
  • Cons: Strong odor, can be toxic to beneficials and aquatic life. Has stricter handling and pre-harvest interval requirements. Generally not recommended for home gardeners due to safer alternatives.
• Systemic vs. Contact Pesticides:
  • Contact Pesticides: Kill pests only when the chemical directly touches them. Most organic options fall into this category. They have little to no residual activity once dry.
  • Systemic Pesticides: Are absorbed by the plant and move through its tissues, making the plant itself toxic to feeding insects. While convenient, they can be problematic as they may make pollen and nectar toxic to pollinators and beneficials. I generally steer clear of systemic pesticides for edible crops like tomatoes in my garden.

Applying Pesticides Safely and Effectively

If you’ve decided a pesticide is necessary, the application process is just as important as the choice of product. This is where attention to detail really pays off, both for efficacy and safety.

1. Read the Label! (Every Single Time): I cannot stress this enough. The label is the law and your most important guide. It tells you:
   • What pests it controls.
   • What plants it can be used on (and which it can’t).
   • Correct mixing ratios.
   • Application methods and rates.
   • Safety precautions (PPE).
   • Re-entry interval (REI): How long you must stay out of the treated area.
   • Pre-harvest interval (PHI): How many days must pass between application and harvest.
   • Storage and disposal instructions.
2. Proper Protective Gear (PPE): Even for “organic” products, wear appropriate gear. At minimum, this usually means long sleeves, long pants, gloves, and eye protection. For stronger chemicals, a respirator might be required.
3. Timing of Application:
   • Time of Day: Apply in the early morning or late evening when temperatures are cooler and winds are calm. This reduces drift, minimizes evaporation, and, crucially, avoids spraying during peak pollinator activity (saving your bees and other beneficials).
   • Before Harvest: Always observe the pre-harvest interval (PHI) on the label to ensure any residues have broken down to safe levels.
   • Weather: Avoid applying before rain, which can wash off the product, making it ineffective and potentially polluting waterways.
4. Targeting the Pest, Not Beneficials: Focus your spray on the affected areas and the pests themselves. If you’re dealing with aphids on the undersides of leaves, aim there, rather than broadly spraying the entire plant.
5. Mixing and Calibration: Don’t guess! Measure accurately. Too little, and it’s ineffective; too much, and you risk plant damage and environmental harm. Clean your sprayer thoroughly after each use.
6. Disposal: Never pour leftover pesticides down the drain or onto the ground. Follow label instructions for proper disposal, which often involves taking them to a hazardous waste facility.

My Personal Take on Tomato Pest Management

After many seasons of dirt under my fingernails and plenty of triumphs (and a few disappointments!), my philosophy on the “best pesticide for tomato plants” has really solidified. It’s not about finding that single magic bullet, but rather becoming a savvy steward of your garden ecosystem. I’ve learned that patience and observation are my most powerful tools.

I always start with prevention – healthy soil, good spacing, attracting those wonderful ladybugs and lacewings. When I spot a problem, my first instinct is to try the most benign method: hand-picking hornworms, blasting aphids with a strong stream of water, or simply squishing a few stink bugs. If those steps aren’t enough, I’ll move to targeted organic solutions like neem oil or insecticidal soap, making sure to apply them responsibly and at the right time of day to protect my pollinators.

The satisfaction of harvesting a basket full of blemish-free, sun-warmed tomatoes, knowing I nurtured them responsibly, is truly unparalleled. It’s a testament to the fact that you *can* have a thriving, productive tomato garden without resorting to harsh chemicals from the get-go. It’s all about balance, continuous learning, and a good dose of persistence!

Frequently Asked Questions (FAQs)

Is it safe to eat tomatoes sprayed with pesticides?

Yes, generally, it is safe to eat tomatoes sprayed with pesticides, provided you follow the product label instructions diligently. The key is to observe the “Pre-Harvest Interval” (PHI) listed on the pesticide label. This indicates the minimum number of days that must pass between the last application of the pesticide and the harvest of the crop. This interval ensures that any pesticide residues have degraded to levels deemed safe for consumption by regulatory agencies.

Furthermore, regardless of whether you’ve used pesticides or not, it’s always a good practice to thoroughly wash your tomatoes before eating them. This helps remove any surface residues, dirt, or potential pathogens. For organic pesticides, residues are generally minimal and break down quickly, but proper washing is still recommended.

How often should I spray my tomato plants?

There’s no fixed schedule for spraying tomato plants; it entirely depends on the specific pest, the product you’re using, and the severity of the infestation. My rule of thumb is to spray only when necessary and not as a routine. Here’s a general guideline:

First, identify the pest and assess the infestation level. For light infestations, hand-picking or a strong water spray might be enough. If you opt for a pesticide, always refer to the product label for specific reapplication intervals. For instance, insecticidal soaps might need to be applied every 5-7 days for an active infestation because they have no residual effect, while neem oil might be every 7-10 days. Avoid over-spraying, as this can harm your plants, build pest resistance, and kill beneficial insects. Regular monitoring is your best tool to determine when a reapplication might be warranted.

Can I make my own homemade pesticide?

Many gardeners experiment with homemade pest remedies, and some can be effective for very minor issues. Common homemade sprays include mixtures of dish soap and water, garlic sprays, or chili pepper concoctions. These might deter certain soft-bodied insects or provide a repellent effect.

However, I always urge caution with homemade solutions. The concentration of active ingredients can be inconsistent, leading to either ineffective treatment or, worse, phytotoxicity (plant damage) from too strong a mixture. Dish soaps, for example, are not the same as insecticidal soaps; they can strip natural waxes from plant leaves, causing damage. When using any homemade solution, test it on a small section of a leaf first and wait 24-48 hours to observe for adverse reactions before applying to the entire plant.

What’s the difference between organic and synthetic pesticides?

The primary difference lies in their origin and chemical structure. Organic pesticides are derived from natural sources, such as plants (like neem oil or pyrethrin), minerals (like diatomaceous earth), or microorganisms (like Bacillus thuringiensis). They are generally less persistent in the environment and often target pests through non-toxic means (e.g., suffocation by oils, gut disruption by Bt). They tend to break down more quickly and often have lower toxicity to non-target organisms once dry.

Synthetic (or conventional) pesticides are manufactured chemicals created in a lab. They are often designed to be highly effective and long-lasting against a broad spectrum of pests. While powerful, they can have a greater potential for environmental persistence, harm to beneficial insects, and stricter safety protocols due to their chemical properties. The choice between the two often comes down to your personal gardening philosophy, the severity of the pest problem, and your commitment to Integrated Pest Management principles.

When is the best time of day to spray?

The best time of day to spray pesticides (whether organic or synthetic) is typically in the early morning or late evening. There are a few critical reasons for this:

• Reduced Wind: Winds are usually calmer during these times, which minimizes spray drift. This ensures the product lands on your intended target and not on neighboring plants, beneficial insects, or yourself.
• Cooler Temperatures: Applying sprays during the cooler parts of the day reduces the risk of phytotoxicity (leaf burn) to your plants, especially with oil-based products or insecticidal soaps. High temperatures can cause chemicals to volatilize too quickly or intensify their effect on plant tissue.
• Protecting Pollinators: Bees and other beneficial pollinators are generally less active in the early morning or late evening. Spraying during these times allows the product to dry on the foliage before pollinators begin their foraging activities, significantly reducing the risk of harming these vital insects.

Are there any “systemic” organic pesticides?

When most people think of systemic pesticides, they usually picture synthetic chemicals that are absorbed by the plant and move throughout its tissues, making the entire plant toxic to feeding pests. In the traditional sense, truly systemic organic pesticides that work in this exact manner are not widely available or common for home gardeners.

However, some natural products can have a “quasi-systemic” or translaminar effect, meaning they can penetrate the leaf surface and provide some protection within the leaf tissue, or they can be absorbed to a very limited extent. Neem oil is a good example; while primarily a contact and anti-feedant, its active compounds (azadirachtin) can be absorbed by the plant and translocated in a very limited way, contributing to its effectiveness against certain pests that feed on plant sap. Still, this is not the same widespread systemic action as many synthetic chemicals. For edible plants like tomatoes, relying on contact organic pesticides and robust IPM is generally preferred over anything with true systemic action.

How do I know if I have a pest problem before it’s too late?

The secret here is regular, diligent observation, folks! I recommend making it a daily habit to stroll through your tomato patch, truly looking at your plants. Here’s what to look for:

1. Inspect Leaf Undersides: Many pests, like aphids, whiteflies, and spider mites, love to hide on the undersides of leaves where they’re protected from sun and rain. Use a magnifying glass if you have trouble seeing tiny critters.
2. Check New Growth: Pests often target tender new shoots and buds. Look for distorted growth, curling leaves, or sticky residue (honeydew).
3. Spot Unusual Holes or Chewing: Large chunks missing from leaves can signal hornworms. Tiny, round holes are often flea beetles. Look for their tell-tale droppings (frass) too.
4. Webbing: Fine, delicate webbing between leaves or in leaf axils is a dead giveaway for spider mites.
5. Discoloration: Yellowing, bronzing, or stippling on leaves can indicate sap-sucking insects like spider mites or aphids.
6. Sudden Wilting: While often a sign of watering issues or disease, it can sometimes indicate root-feeding pests or stem damage (like from cutworms).
7. Shake and See: Gently shake a branch over a white piece of paper. Tiny specks that fall and start crawling are likely pests.

Early detection is truly your best friend. Catching a problem when it’s just a few bugs is far easier to manage than waiting until your plants are overrun!

Ultimately, the “best pesticide” for your tomato plants isn’t a single product, but a well-thought-out, adaptable strategy centered on Integrated Pest Management. By combining preventative measures, encouraging beneficial insects, and using targeted, least-toxic solutions only when absolutely necessary, you’ll be well on your way to harvesting delicious, healthy tomatoes season after season. Happy gardening!
