What is Eating My Tomato Plant Stalk

Tomato plants are a popular addition to any garden, but they can be targeted by pests that can damage or destroy the plants. One of the most common problems gardeners face is damage to the tomato plant stalk. There are several potential culprits behind this type of damage, and it is important to identify the cause in order to take appropriate action.

Cutworms

One of the most common causes of damage to tomato plant stalks is cutworms. These pests are caterpillars that feed on the stems of plants at or just below the soil surface. They typically attack young plants, and will often completely sever the stem, killing the plant. Signs that cutworms are the culprit behind your damaged tomato plant may include plants that are wilting, yellowing, or simply collapsing. Some gardeners may spot the caterpillar itself if they inspect the plant closely.

Cutworm Prevention and Treatment

The best way to prevent cutworm infestations is to take steps to keep them out of your garden in the first place. This may involve tilling soil thoroughly in the fall to reduce the number of eggs that overwinter in the ground. Additionally, using a barrier of some sort, such as a collar made of cardboard or pipe wrap, can be effective in keeping cutworms away from your plants. If your plants are already under attack, removing the caterpillar and placing it in a bucket of soapy water can help to control the infestation.

Borers

Another potential source of damage to tomato plant stalks is borers. These pests are the larvae of certain types of moths, and typically bore into the stem of the plant, where they feed on the internal tissue. Signs that borers are the cause of your problem may include wilted or dead branches, or tiny holes in the stem where the borers have entered.

Borer Prevention and Treatment

To prevent borers, be sure to keep your garden tidy and free of debris, as this can harbor overwintering larvae. Additionally, taking steps to attract beneficial insects, such as parasitic wasps, can help to control borer populations. For plants that are already under attack, removing the infested section of the plant and destroying it can help to control the spread of the problem.

Rodents

In some cases, rodents such as rats, squirrels, or mice can be responsible for damage to tomato plant stalks. These animals may chew on the stalk or simply invade the soil around it, causing damage to the root system. Signs of a rodent infestation may include holes in the soil near the plant or droppings around the base of the plant.

Rodent Prevention and Treatment

To prevent rodents, be sure to keep your garden clean and tidy, with no food or debris that can attract these animals. Additionally, using a physical barrier such as chicken wire around the base of the plant can be effective in preventing rodents from accessing the plant. Trapping or extermination may be necessary if an infestation is already present.

In Conclusion

Identifying the source of damage to your tomato plant stalk is important in order to take the appropriate steps to prevent or control the problem. Whether the culprit is cutworms, borers, or rodents, there are steps you can take to protect your plants and keep them healthy all season long.
