Abstract

The invention relates to the technical field of pesticides, in particular to a multi-effect pesticide composition, which is prepared from the following components in parts by weight: 0.001-1 parts ofbrassinolide, 1-25 parts of mepiquat chloride, 2.5-30 parts of paclobutrazol, 1-3 parts of strigolactone, 1-5 parts of a corn stigma extracting solution and 1-5 parts of liquorice root extract. The invention also relates to application of the multi-effect pesticide composition in a cotton or peanut planting process. The application can be used for solving the problems of cotton flower falling, budfalling and boll falling and promoting bud falling regeneration. The problems of vigorous growth and lodging of the overground parts of the peanuts can be effectively controlled, the maturing rate and the grain plumpness rate of the peanuts are increased, a good yield increasing effect is achieved, and the influence of residues of paclobutrazol in soil on next-stubble crops is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a multi-effect pesticide composition and its application. Background technique [0002] For decades, in the process of cotton planting and production in my country, the rate of falling flowers, buds and bolls has been around 60%, which is a persistent problem affecting the high yield of cotton. , The core problem of Baoling. [0003] Peanut is an important oil crop, cash crop and foreign exchange earning crop in my country. It plays an important role in the supply of edible oils and fats, food processing, export earning foreign exchange and farmers' income increase. South China is the main production area of ​​peanuts in my country, which has important resource advantages and location advantages. The prior art uses mepiperium and uniconazole as microemulsions as active ingredients, which can effectively regulate the growth and development of peanuts, control the e...
