Abstract

A composite microemulsion used as plant growth regulator for wheat, soybean, peanut, paddy rice, etc contains mepiqnat chloride, uniconazole, cosolvent, emulsifier, stabilizer and water.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and the invention relates to a microemulsion of a plant growth regulating composition, in particular to a plant growth regulator containing mepiperium and dinoconazole as active ingredients, which is prepared by adding other inert ingredients of microemulsion. Background technique [0002] The prosperity and lodging of crops such as wheat, soybeans, peanuts, and rice have brought great losses to crop production, and also limited the further improvement of yields. Patent EP127944, Duan Liusheng et al. (Journal of Pesticides, 2002) disclosed that mepiperinium and paclobutrazol were mixed to prevent wheat from lodging, but paclobutrazol remained in the soil for a long time, and there were environmental unsafe factors. Uniconazole is a triazole plant growth regulator, its physiological activity is about 5-12 times that of paclobutrazol, and its safety is better than that of paclobutrazol. Mixed...
