Abstract

The invention discloses a root-knot nematode preventing pesticide. The root-knot nematode preventing pesticide is prepared from the following materials, by weight percentage, 1-2% of albendazole, 50-70% of solvent and 28-49% of auxiliaries. The albendazole is a market raw pesticide with a content of 98%; the solvent is composed of organic solvent and inorganic solvent, wherein the organic solvent is dimethyl formamide or dimethyl solfoxide, and the inorganic solvent is water; the auxiliaries are composed of emulsifier and penetrant, wherein the emulsifier is dodecyl benzene solfonate or alkylphenol polyoxyethylene, and the penetrant is hypertonic azone or market anhydrous penetrant T. The preparation method of the root-knot nematode preventing pesticide comprises dissolving the raw albendazole with the organic solvent, and then adding in and uniformly stirring the emulsifier and the penetrant inside the solution; performing filtering, discarding filter residues, filling the filtered solution into bottles and performing packaging and storage to obtain the root-knot nematode preventing pesticide. The root-knot nematode preventing pesticide achieves significant root-knot nematode killing effects and is safe in application and applicable to preventing root-knot nematode in vast rural areas.

Description

technical field [0001] The present invention relates to insecticides, specifically, belongs to insecticides containing organic compounds, and furthermore, belongs to insecticides for preventing and controlling root-knot nematodes. technical background [0002] Root-knot nematode (Meloidogyne) is a highly specialized omnivorous plant pathogenic nematode. [0003] Nematodes that are known to damage vegetables mainly include root-knot nematode high pedicle, root-knot nematode peanut, root-knot nematode northern and root-knot nematode southern. Root-knot nematode has a wide range of hosts and often harms more than 30 kinds of vegetables such as melons, solanaceous fruits, beans, radishes, carrots, lettuce, and cabbage. It can also spread some fungal and bacterial diseases. [0004] Prothiol, also known as albendazole ( Albendazole ), is a benzimidazole derivative, and is an efficient, safe and broad-spectrum imidazole insecticide. [0005] In recent years, the problem of prev...
