There may be several factors that could be infesting your tomatoes. Some common pests that may infest tomato plants include aphids, whiteflies, spider mites, and cutworms. These pests can cause damage to the plant by feeding on the leaves, stems, and fruit. They can also introduce diseases that can further weaken the plant.
Aphids are small, soft-bodied insects that suck sap from the plant, causing stunted growth, curled leaves, and a decline in fruit production. Whiteflies are tiny insects that feed on the underside of leaves, causing yellowing and wilting. Spider mites are very small pests that feed on the plant’s sap, causing yellow stippling on the leaves.
Cutworms are larvae of various moth species that feed on the stems of young plants, cutting them off at the soil line. This can lead to the plant wilting and dying.
To control these pests, it is important to regularly inspect your plants for signs of infestation. Remove any affected leaves or stems, and consider using insecticidal soap or neem oil to treat the plant. You can also attract natural predators like ladybugs or lacewings to help control aphids and other pests.
Proper watering and fertilization can also help keep your plants healthy and more resistant to pest infestations. By taking proactive measures, you can help protect your tomato plants from infestation and ensure a healthy harvest.
