Mixed pesticide capsule preparation for preventing and treating nematode and soil-borne disease

Abstract

The invention relates to a composition comprising soil fumigant iodomethane and chloropicrin in reasonable proportions and a processing method of a capsule preparation corresponding to the composition. The preparation is suitable for preventing root-knot nematodes and other soil nematodes on crops, such as beans, fruits including strawberries in orchards and grapes in vineyards, flowers, vegetables including asparagus, celery, carrots and sweet potatoes,, Chinese medicinal herbs, and the like, and the compound can favorably prevent soil-borne pathogens, such as the Fusarium spp., Phytophthora spp., and the like.

Description

technical field [0001] The present invention relates to utilizing compound iodomethane (common name is iodomethane, chemical formula CH 3 1) Control root-knot nematodes and other soil nematodes on protected crops such as vegetables, strawberries, flowers, melons, etc., the compound has a good inhibitory effect on soil-borne pathogen Fusarium (Fusarium spp); spp), Phytophthora (Phytophthora spp) fungi also have a good control effect. Chloropicrin can effectively control fungi of the genus Rhizobasidiomycetes, Spinosa, Cylindromyces, Fusarium, Phytophthora, Septoria, Pythium, Rhizoctonia, and Verticillium , It is also effective against Agrobacterium bacteria, and it also has certain effects on underground pests and soil nematodes. Methyl iodide has high activity but high cost, and chloropicrin is less effective in controlling root-knot nematodes, so the mixed use of chloropicrin and methyl iodide improves the control effect on soil nematodes. The specific method is to mix the...
