Definition - What does Nematode mean?

Nematodes are the most numerous microscopic worm in the world, with 20,000 known types. A handful of soil may contain thousands of nematodes. The free-living variety is the most abundant, with many of them feeding on fungi, bacteria, or even other nematodes.

Nematodes contribute to the decomposition process by feeding on and breaking down organic matter. Although many varieties are beneficial, there are those that are parasitic pathogens infecting humans, animals, and plants.

MaximumYield explains Nematode

Nematodes are highly adaptable to nearly every environmental condition and location. They’re found on every continent, including Antarctica. Nematodes are present in seawater, deserts, and the frozen tundra. In almost every environment they live, nematodes outnumber all other multi-celled animals.

Parasitic nematodes can infect plants and will eat virtually any part of it, including roots, stems, leaves, flowers, and seeds.

Plants infected by parasitic nematodes may be unable to support their own weight and possess weak stems and yellowed or spotted leaves. Nematodes that feed on the roots also deprive the plant of nutrients and water, resulting in a droopy, sick-looking appearance.

There are many products on the market for the treatment of parasitic nematodes and many non-chemical treatments such as diatomaceous earth.
