Eelworm
Eelworm, very small you can't see them with the unaided eye. Most eelworms are .1 to .5 millimeters long making them very hard to study and find. They are all over the world! They live off plants as their host, tomatoes one of the most critically affected. Eelworms thrive in very moist conditions in soil. They require water around the soil before they are able to move, and the eggs can't hatch without water. Eelworms are parasites that live off the cells of their host. They excrete enzymes that make plant cells bigger, make lumps ranging from 1mm to 10mm in diameter. They can cause plant death in some cases.
