A nematicide is a type of chemical pesticide used to kill plant-parasitic nematodes. Nematicides have tended to be broad-spectrum toxicants possessing high volatility or other properties promoting migration through the soil. Aldicarb (Temik), a carbamate insecticide marketed by Bayer CropScience, is an example of a commonly used commercial ...
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. Soil solarization, or heating and insulating of the soil, can cause nematode death although heat may not penetrate deep enough to kill all nematodes. Cover crops such as sunn hemp and some species of ...
This list of pest-repelling plants includes plants used for their ability to repel insects, nematodes, and other pests.They have been used in companion planting as pest control in agricultural and garden situations, and in households.
Chitosan, a natural biocontrol, elicits plant defense responses to destroy parasitic cyst nematodes on roots of soybean, corn, sugar beet, potato, and tomato crops without harming beneficial nematodes in the soil. [66] Soil steaming is an efficient method to kill nematodes before planting a crop, but indiscriminately eliminates both harmful and ...
These chemicals then kill the nematodes by active suppression because they are toxic to the nematode. Crop rotation is another form of control for X. americanum. It has been shown that certain non-host plants may deny the nematode population an adequate food source for reproduction, and thus greatly reduce its population in the soil.
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 ...
Tylenchulus semipenetrans, also known as the citrus nematode or citrus root nematode, is a species of plant pathogenic nematodes and the causal agent of slow decline of citrus. T. semipenetrans is found in most citrus production areas and diverse soil textures worldwide. Their feeding strategy is semi-endoparasitic and has a very narrow host ...
The nematode moves through pores in the soil, and finds a root to feed on. It inserts its stylet into an epidermal cell on the plant, feeds for a certain amount of time, then moves along to a different locations, and feeds on a different root.
