Abstract

The invention discloses a spreading oil insecticidal composition containing chlorpyrifos and buprofezin. The insecticidal composition is prepared from a mixture of chlorpyrifos and buprofezin, emulsifier, solvent, nonionic surfactant, cosolvent and water dispersing agent. A preparation method for the insecticidal composition comprises the following steps of: mixing the chlorpyrifos and the buprofezin in the emulsifier, heating to be at the temperature of between 20 and 80 DEG C, preserving heat, adding the solvent, the nonionic surfactant, the cosolvent and the water dispersing agent under a stirring condition, fully mixing uniformly, and standing, so as to obtain an spreading oil agent. When the composition is used, water or soil is not required, any plant protection instrument is not required, and pesticide liquid is directly dropped into a paddy field, can be quickly and uniformly dispersed in the whole field to form a pesticide film layer and upwards climbs for 20 centimeters from the base of rice stems, so that an aim of preventing and controlling pests is fulfilled; and the composition has the characteristics of high efficiency, long-acting effect, low toxicity, safety, convenience for use, reduction of labor and cost and the like.

Description

technical field [0001] The invention relates to a preparation method of a film spreading oil insecticidal composition containing chlorpyrifos and buprofezin and its application in controlling rice pests. Background technique [0002] Chlorpyrifos and Buprofezin are two commonly used insecticides. [0003] The molecular formula of chlorpyrifos is: O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) phosphorothioate. [0004] Application: Generally, chlorpyrifos has formulations such as emulsifiable concentrate, microemulsion, and granule. It is an organophosphate insecticide with contact killing, stomach poisoning and fumigation effects. The residual period on the leaves is not long, but the residual period in the soil is longer, and the control effect on underground pests is better. It is suitable for cotton, leafy vegetables, apples, citrus, rice, sugarcane and other crops. [0005] Control objects: rice leaf roller, rice thrips, rice gall midge, rice planthopper, rice leafhopper....
