Soil steaming is an efficient method to kill nematodes before planting a crop, but indiscriminately eliminates both harmful and beneficial soil fauna. The golden nematode Globodera rostochiensis is a particularly harmful pest that has resulted in quarantines and crop failures worldwide.
Nematodes are spread through the soil and through infested banana plantlets. The best option is to ensure that banana corms are free of any nematodes prior to planting. Researchers in Hawaii found that a hot-water treatment at 50 °C for 10 minutes was enough to kill all nematodes in a corm 2–6 inches thick.
Foliar nematodes occur throughout the United States in greenhouse and nursery settings. Foliar nematodes travel in films of water, swimming up the stems of plants and entering leaf tissue through stomata. The nematodes are transmitted plant to plant by splashing, overhead irrigation, rainfall, and other forms of dripping water. They can also be ...
Nematodes play an astoundingly wide range of ecological roles that scientists are only beginning to understand. Word from the Smokies: Scientist uncovers secret life of soil through study of nematodes
They exist in soil in areas with hot climates or short winters. About 2000 species of plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss. [1] Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthate and ...
However, increasing levels of anthelmintic resistance have been observed, driving the search for new treatment and prevention options. [4] Larvae of animal-pathogenic nematodes are found in soil. [4] The prospect of treating contaminated soils with nematode pathogenic fungi such as H. anguillulae has shown potential to reduce nematode ...
