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 ...
Heterorhabditis bacteriophora is a species of entomopathogenic nematode known commonly as beneficial nematodes. They are microscopic and are used in gardening as a form of biological pest control . They are used to control ants , fleas , moths , beetles , flies , weevils , and other pests.
They have been used in companion planting as pest control in agricultural and garden situations, and in households. Certain plants have shown effectiveness as topical repellents for haematophagous insects, such as the use of lemon eucalyptus in PMD , but incomplete research and misunderstood applications can produce variable results.
Biological control agents of weeds include seed predators, herbivores, and plant pathogens. Biological control can have side-effects on biodiversity through attacks on non-target species by any of the above mechanisms, especially when a species is introduced without a thorough understanding of the possible consequences.
Meloidogyne occurs in 23 of 43 crops listed as having plant-parasitic nematodes of major importance, ranging from field crops, through pasture and grasses, to horticultural, ornamental and vegetable crops. [4] If root-knot nematodes become established in deep-rooted, perennial crops, control is difficult and options are limited. [citation needed]
The specific chemical control utilized is nematicide toxins, including Aldicarb, Enzon, Oxamyl, and Cadusafos (Rugby). The most effective nematicide against Meloidogyne javanica is Rugby in a dosage of 8 ppm (Soltani 2013). The chemical control can be used throughout the nematodes life cycle, as the nematicide can kill the nematode at any stage.
