Abstract

The invention relates to a defoliation agent, especially a mixture containing thiadizuron and tyramid, and its application in cotton crops. Contains active ingredients thiadizuron and tyramid, wherein the weight ratio of thiadizuron to tyramid is 1:1-500:1. The weight percentage of the thiadizuron and tyramid in the composition is 1%-50%. Contains thiadidiuron, tyrazolin and one or more preparation auxiliary agents. The defoliant is used for defoliation of plants. The defoliant is used to reduce plant regrowth. The plant is a cotton plant. The cotton plants are transgenic or non-transgenic cotton plants.

Description

technical field [0001] The invention relates to a defoliation agent, especially a mixture containing thiadizuron and tyramid, and its application in cotton crops. Background technique [0002] Cotton is the most widely used textile fiber. It is planted in most parts of our country and is a very important economic crop. The unlimited growth habit of cotton and the drop of ambient temperature in the late growth period often lead to the late formation of peripheral bolls and upper bolls that cannot be opened and matured normally, which affects yield and fiber quality. This late-maturing phenomenon of cotton is ubiquitous, and chemical ripening is the application of ripening agents to solve the late-maturing problem of cotton. Harvesting is an important link in cotton production, but the leaves remaining on the cotton plant not only affect the harvesting speed (especially mechanical harvesting), but also affect the grade of cotton. Chemical defoliation is to make most of the l...
