What to Put on Tomato Plants for Insects

1. Neem Oil

Neem oil is a natural insecticide that is effective against a range of insects that can affect tomato plants. It works by disrupting the nervous system of insects, causing them to stop feeding and eventually die. Neem oil is also safe to use around humans and pets because it is non-toxic. To use, mix 1 tablespoon of neem oil with 1 gallon of water and apply the mixture to the tomato plants using a sprayer.

2. Diatomaceous Earth

Diatomaceous earth is a powder made from the fossilized remains of diatoms, a type of algae. It is effective against insects by absorbing their moisture, which leads to dehydration and death. To use, apply a thin layer of diatomaceous earth around the base of the tomato plants. It is important to wear a mask when applying diatomaceous earth because the fine particles can be harmful if inhaled.

3. Garlic Spray

Garlic is a natural insecticide that can be used on tomato plants to repel insects. To make a garlic spray, crush a few garlic cloves and mix them with water. Allow the mixture to sit overnight, then strain it and pour it into a sprayer. Apply the garlic spray to the tomato plants, making sure to cover both the tops and bottoms of the leaves.

4. Insecticidal Soap

Insecticidal soap is a ready-to-use spray that can be used on tomato plants to control a range of insects, including aphids, spider mites, and whiteflies. It works by disrupting the outer cells of the insect, causing it to dry out and die. To use, spray the insecticidal soap directly on the tomato plants, making sure to coat both the tops and bottoms of the leaves.

5. Beneficial Insects

Beneficial insects, such as ladybugs and lacewings, can be introduced to the garden to control insect populations. These insects eat a variety of insects that can damage tomato plants, including aphids and thrips. To attract beneficial insects, plant flowers such as marigolds and cosmos in your garden. You can also purchase live ladybugs or lacewings and release them into your garden.

In conclusion, there are several options available for controlling insect populations on tomato plants. Whether you prefer natural or chemical solutions, there is a product or technique that can help keep your tomato plants healthy and insect-free. With a little effort, you can enjoy a bountiful crop of tomatoes without the hassle of insect damage.
