In order to protect the roots and leaves of plants from the above-mentioned pathogens, and ensure the plants can grow healthily.

The role of nematodes There are two sides to everything, and the same goes for nematodes. Let me talk about the positive side first. Soil nematodes play a very important role in the decomposition of organic matter, nutrient conversion and energy transfer, and are an important part of the soil ecosystem. For example, nematode excreta can contribute 19% of the dissolved nitrogen in the soil. At the same time, nematodes are also used as soil indicator organisms to evaluate the ecosystem biological effects, soil health, ecosystem succession, or disturbance levels. Almost every plant can be parasited or harmed by one or more nematodes. Some nematodes feed on plants and are commonly referred to as ‘eelworms’ in the British-speaking world. Most plant …
