Tomatoes and Marigolds Pest Control

Pest control is an essential part of gardening. There are many methods to control pests, including the use of pesticides. However, pesticides can be harmful to the environment and human health. In recent years, natural pest control has gained popularity as a safer and more sustainable option. In this article, we will discuss how tomatoes and marigolds can be used for natural pest control.

Why Use Tomatoes and Marigolds?

Tomatoes and marigolds are two common plants in gardens. They have been found to repel certain insects and attract beneficial insects. This makes them ideal for natural pest control.

Repelling Insects

Tomatoes contain a chemical called solanine, which is toxic to some insects, including aphids and whiteflies. Marigolds contain a chemical called pyrethrin, which repels many insect pests, including mosquitoes, whiteflies, and nematodes.

Attracting Beneficial Insects

Tomatoes and marigolds also attract beneficial insects that prey on garden pests. For example, ladybugs and lacewings are attracted to marigolds and feed on aphids, mealybugs, and other soft-bodied insects. Parasitic wasps are attracted to tomato plants and lay their eggs on tomato hornworms, which then hatch and kill the hornworms.

How to Use Tomatoes and Marigolds for Pest Control

Here are some ways to use tomatoes and marigolds for natural pest control:

Planting Marigolds Around Tomatoes

One way to use marigolds for pest control is to plant them around tomato plants. This can help repel pests and attract beneficial insects. Plant marigolds in a border around the tomato plants, or interplant them among the tomatoes.

Using Marigold Extracts

Marigold extracts can also be used as a natural insecticide. To make a marigold extract, chop up marigold flowers and leaves and soak them in water overnight. Strain the mixture and spray it on your plants to repel pests.

Interplanting Tomatoes with Herbs

Another way to use tomatoes for pest control is to interplant them with herbs that repel pests. For example, basil and mint repel mosquitoes and other flying insects. Plant these herbs around your tomato plants to help keep pests away.

Using Companion Planting

Companion planting is the practice of planting certain plants together to benefit each other. Tomatoes and marigolds are an example of companion planting for pest control. Other examples include planting beans with corn to fix nitrogen in the soil, or planting carrots with onions to repel carrot flies.

Other Natural Pest Control Methods

In addition to using tomatoes and marigolds for natural pest control, there are other methods you can try:

Hand-Picking Pests

One effective method of pest control is to simply remove the pests by hand. This works well for larger insects like caterpillars and beetles. Check your plants regularly for signs of pests and remove them as soon as you see them.

Using Insecticidal Soap

Insecticidal soap is a natural insecticide made from potassium salts of fatty acids. It works by breaking down the protective coating on insects, causing them to dehydrate and die. Insecticidal soap is safe for humans, pets, and beneficial insects.

Introducing Beneficial Insects

You can also introduce beneficial insects into your garden to help control pests. Ladybugs, lacewings, and parasitic wasps are all beneficial insects that prey on garden pests. You can buy them online or at your local garden center.

Tomatoes and marigolds are two common plants in gardens that can be used for natural pest control. They repel certain insects and attract beneficial insects, making them an effective and sustainable option for pest control. By using these plants along with other natural pest control methods, you can keep your garden healthy and pest-free without harming the environment.
