Gall nematodes

These pests of tomatoes, although small, but very numerous (the female debugs about 2000 eggs). Different species of these parasites can choose the most diverse places for their habitat: stems, leaves, roots and even seeds. They damage plant tissues, feeding on their beneficial substances. Nematodes in large quantities accumulate in the ground when planting tomatoes every year in the same place. Pests can form thickened roots in the roots, laying eggs in them, so the roots do not perform their functions at full capacity. The disease of plants is initially imperceptible, but after a while can be of a massive nature. Damaged by nematodes, the plant has weak immunity, so it easily succumbs to various diseases.

Preventive control of nematodes should include a crop rotation.
