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 ...
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. It can be controlled, however.
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 ...
The chemical control can be used throughout the nematodes life cycle, as the nematicide can kill the nematode at any stage. Additionally, a more recent development in the management of Meloidogyne javanica is seed treatment.
Nematode-trapping fungi are mostly concentrated in the upper part of the soil, in pastures, leaf litter, mangroves and certain shallow aquatic habitats. They employ techniques such as adhesive hyphal strands, adhesive knobs, adhesive nets formed from hyphal threads, loops of hyphae which tighten round any ensnared nematodes and non-constricting ...
They usually live in soil and many species trap or stun nematodes (nematophagous fungus), while others attack amoebae or collembola. Fungi that grow on the epidermis, hair, skin, nails, scales or feathers of living or dead animals are considered to be dermatophytes rather than carnivores. Similarly, fungi in orifices and the digestive tract of ...
