How to get rid of cutworms on tomato plants: Spray

Tomato plants are a great addition to any garden, but they are also prone to pests such as cutworms. These insects have a voracious appetite for the young tomato plants, and if left unchecked, can cause significant damage to the crop. Thankfully, there are several ways to effectively get rid of cutworms on tomato plants, with the use of spray being one of the most popular. Here's how to do it:

What is a cutworm?

Before we dive into the solution, it's important to understand what a cutworm is. Cutworms are actually the larvae of several species of moths belonging to the family Noctuidae. These pests usually appear during the early spring and late fall months. Cutworms are primarily nocturnal and often stay underground during the day, which makes it difficult to spot them. When they do come out, they can cause significant damage to tomato plants by cutting through the stems near the soil line.

Using spray to get rid of cutworms:

Sprays are one of the most effective ways to control cutworms on tomato plants. There are several types of sprays that you can use, including organic and chemical options. Here's how to get started:

Step 1: Identify the signs of a cutworm infestation

The first step is to identify if your tomato plant has been infested with cutworms. Signs that you may have a cutworm problem include wilting, yellowing or flopping leaves, and the presence of small chew marks on the stem of the plant. Cutworms are usually nocturnal, so it's essential to check your plants during the night.

Step 2: Choose a spray

Once you have identified the infestation, you need to choose a spray that is appropriate for your needs. Organic options include neem oil, insecticidal soap, and Bacillus thuringiensis (Bt), a bacteria that specifically targets cutworms. Chemical options include carbaryl, with Bacillus thuringiensis being the most effective.

Step 3: Preparation

Before you start spraying your tomato plants, it's essential to prepare them correctly. This includes removing any debris, such as plant material or mulch, from the base of the plant. This will help expose the cutworms and ensure that the spray reaches them. Additionally, you should also remove any plants that are already dead or dying, as they may attract more cutworms.

Step 4: Spray the tomato plants

Once you've prepared your tomato plants, it's time to start spraying. Apply the spray liberally to the entire plant, including the base of the stem. Make sure you follow the manufacturer's instructions and wear protective clothing when applying chemical sprays. Repeat the spray every week until you've completely eradicated the cutworms.

Preventative measures

In addition to using sprays to control cutworms, you can also take preventative measures to reduce the risk of infestation. One option is to use physical barriers such as collars, made from cardboard or paper, around the base of the tomato plant. This will help prevent cutworms from crawling up the stem. Additionally, maintaining good garden hygiene, such as removing dead plant material and rotating crops, can also help keep cutworms at bay.

Conclusion

Cutworms can cause significant damage to your tomato crop, but with the use of sprays, you can effectively control their spread. Remember to follow the manufacturer's instructions when using chemical sprays and take preventative measures to reduce the risk of infestation. With these steps in place, you can enjoy a bountiful tomato harvest without the worry of cutworms.
