Introduction

Tomatoes are an essential part of many people's diets and are quite easy to grow. However, cutworms can be a significant issue for tomato plants. These small, brownish larvae can chew through the stem of the plant at the soil level, killing it before it can produce any fruit. It is essential to take steps to prevent cutworms from attacking your tomato plants to ensure a healthy and bountiful harvest. Here's how to prevent cutworms on tomato plants.

Using Physical Barriers

One of the easiest ways to prevent cutworms from attacking your tomato plants is to use physical barriers. Cutworms primarily feed on young plants, so placing a collar of paper or cardboard around the base of your tomato plant will create a barrier they cannot easily penetrate. You can also use plastic wraps or even toilet paper rolls to create these barriers. It Is essential to make sure that these barriers are flush with the soil surface and are not blown away by the wind.

Companion Planting

Another way to prevent cutworms from attacking your tomato plants is through companion planting. Planting chamomile, dill, or parsley in the same bed as your tomato plants can attract beneficial insects, such as parasitic wasps, that prey on cutworms. Additionally, marigolds repel cutworms and can be planted in between your tomato plants to keep them at bay. Remember to provide adequate spacing between tomato and other plants to prevent overcrowding.

Biological Control

Another effective way to prevent cutworms from destroying your tomato plants is through biological control. Bacillus thuringiensis is a naturally occurring soil bacterium that can kill cutworms, and it is available in spray or powder form for application in your garden. Using nematodes to control cutworms is another effective biological control method. Nematodes are tiny worms that naturally occur in soil and are effective predators of cutworms. They can be purchased and applied to your garden to help control cutworm populations.

Cultural Practices

Practicing good cultural habits in the garden can also help prevent cutworm infestations. Tilling the soil in the autumn exposes cutworms to the cold temperatures, which can help control their populations come spring. Using crop rotation practices can help break the breeding cycle of cutworms. Failure to practice crop rotation can lead to cutworm populations re-establishing in the same area year after year. Lastly, ensure that you clean the garden beds well from any dead plant debris that can harbor cutworm eggs during the off-season.

Conclusion

In conclusion, cutworms can be a significant problem for tomato plants. However, using physical barriers, companion planting, biological control methods, and good cultural practices can help prevent cutworms from attacking your tomato plants. By following these tips, you can have healthy tomato plants and a bountiful harvest all season long.
