Cotton defoliant

Abstract

The invention relates to a cotton defoliant. The cotton defoliant comprises the following raw materials in parts by weight: 60-70 parts of ethephon, 5-15 parts of thidiazuron, 60-80 parts of magnesium chlorate and 1-2 parts of an 888 pesticide synergist. The cotton defoliant can effectively prevent cotton defoliation from being influenced by activity reduction of thidiazuron at low temperature, speeds up cotton defoliation and improves the defoliation rate.

Description

technical field [0001] The invention relates to a cotton defoliation agent. Background technique [0002] Cotton was once an important strategic material in my country and played a pivotal role in the agricultural economic structure. my country's cotton production ranks among the top in the world. It is a large textile country and the largest cotton consumer. There are 23 provinces, municipalities and autonomous regions that produce cotton. The cotton industry occupies an important position in the national economy. [0003] Due to the unlimited growth habit of cotton and the limitation of climatic conditions, especially with the development of summer sowing cotton, in most cotton areas in my country, when the frost comes, there are always many cotton bolls that are too late to open bolls, and some of them are not grown in late autumn. Some cotton bolls that can barely mature also become post-frost flowers. After frost, the flower quality is very poor, and the use value is v...
