Abstract

The invention relates to a water-dispersible particle which can be used in disinfection. The invention is prepared from following components that 0.4-10 deals of cnidium fruit extractive, 2-20 deals of mixture solvents, 1.5-15 deals of mixture emulsifier, 4-15 deals of mixture lagging cover, and 40-90 deals of corn material. The inventive production is based one multiply adsorptions and lagging technique, while it can disinfect and adjust the growth, with little organic solvent.

Description

Technical field [0001] The present invention relates to the field of pesticides, and more specifically, to a new type of insecticidal and sterilizing water dispersible granules. Background technique [0002] The extract of Cnidium monnieri is a Chinese herbal medicine Cnidium monnieri after cold leaching or hot refluxing to extract alcohol-soluble or ester-soluble substances. It can also be extracted by carbon dioxide critical point extraction. Cnidium extract mainly contains osthol, and it also contains several biologically active compounds such as xanthotoxin, limonene, and ostial. A large number of experimental data have proved that Cnidium extract and Osthole have a strong antifungal effect, and have strong antifungal effects on dozens of insect larvae of Lepidoptera, Homoptera, Diptera, Coleoptera, and protozoa such as Trichomonas. The killing effect. Therefore, Cnidium extract and Osthole have been registered as agricultural pesticides and agricultural fungicides in my coun...
