What to Spray on Tomato Plants for Worms

Tomato plants are highly susceptible to infestations by various types of worms, including tomato fruitworms, corn earworms, and cabbage loopers. These tiny pests can cause significant damage to the leaves, stems, and fruits of the tomato plant if left unchecked. Fortunately, there are several effective sprays that can help control worm infestations in tomato plants.

1. Neem Oil

Neem oil is a natural insecticide derived from the seeds of the neem tree. This organic pesticide effectively repels worms and other insects by disrupting their feeding and reproductive patterns. To use neem oil, mix one tablespoon of neem oil with one gallon of water and a few drops of dish soap. Spray the mixture on the tomato plants, making sure to cover the leaves and undersides of the foliage. Neem oil is safe for humans and pets and can be used up until harvest time.

2. Bacillus Thuringiensis

Bacillus thuringiensis (Bt) is a naturally occurring bacteria that produces a toxin that is lethal to many types of worms, including tomato fruitworms and corn earworms. Bt is available in both a dust and a liquid form and is best applied directly to the affected areas of the tomato plant. Bt is safe for people, pets, and the environment, but be sure to follow the manufacturer's instructions carefully when applying it on tomato plants.

3. Spinosad

Spinosad is an organic pesticide that is derived from a soil microbe. It works by affecting the nervous system of the worms, causing paralysis and ultimately death. Spinosad is available in both a liquid and a powder form and can be mixed with water to create a spray. To use spinosad on tomato plants, mix one tablespoon of the powder or liquid with one gallon of water and a few drops of dish soap. Spray the mixture directly onto the tomato plants, coating the leaves and fruits. Spinosad is safe for pets and people but should be used with caution on beneficial insects like bees and butterflies.

4. Pyrethrin

Pyrethrin is a natural insecticide that is derived from the chrysanthemum flower. It works by targeting the nervous system of the worms, causing paralysis and death. Pyrethrin is available in both a liquid and a powder form and can be used as a spray on tomato plants. Mix one tablespoon of pyrethrin with one gallon of water and a few drops of dish soap. Spray directly onto the tomato plants, making sure to cover the leaves and fruits. Pyrethrin is generally safe for people and pets but can be harmful to beneficial insects like bees and butterflies.

Conclusion

Worm infestations can wreak havoc on tomato plants and their fruits. Using natural insecticides like neem oil, Bacillus thuringiensis, spinosad, and pyrethrin can help control these pests without harming the environment. Always follow the manufacturer's instructions for proper use and application, and be sure to wear protective clothing and gloves when handling these insecticides. With the right treatment, tomato plants can thrive and produce healthy, delicious fruits.
