The most common and dangerous pests of potatoes


Perhaps the most common and perfectly known to all gardeners, without exception, potato pests are Colorado beetles. These insects (moreover, both their adults and their larvae) eat tubers and vegetative organs of plants and are especially troublesome in hot weather, which is extremely favorable for their development.

No less dangerous for potatoes are insects such as click beetles, or rather, their larvae that live in the soil and damage the roots, stem bases and tubers of potatoes. It is these pests that gnaw passages in the tubers, which, as a result, leads to their decay and, as a result, a significant decrease in yield. Naked slugs, worm-like mollusks with a body covered with mucus and a hard tongue covered with sharp teeth, gnaw holes in roots, and sometimes they are almost completely eaten by naked slugs. These pests of potatoes cause the greatest harm in wet years and live mainly in clay or loamy soils in low areas.

The largest potato pests are bears, the length of which can reach four to five centimeters. Both the larvae and the adults of this insect are equally dangerous for potatoes and many other plants, because, making passages near the soil surface, they often damage the stems and roots of plants. But potato nematodes are almost microscopic in size, not exceeding one millimeter, but they are no less dangerous for plants. Nematodes parasitize potato tubers and roots and lead to growth retardation of affected plants, leaf fall and the formation of extremely small tubers.
