Cotton defoliating agent

Abstract

The invention relates to a cotton defoliating agent. The cotton defoliating agent comprises, by weight, 8 to 20 parts of thidiazuron and 80 to 92 parts of magnesium chlorate. The cotton defoliating agent is used when cotton bolls crack at about 70%, defoliation is started after 3 days, the cotton leaf defoliating rate reaches over 85% after 6 days, the cotton leaf defoliating rate reaches a peak after 10 days, and the cotton leaf defoliating rate reaches over 95%. The cotton defoliating agent is free of harm to a plant and boll opening is normal.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a cotton defoliant. 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 ...

Problems solved by technology

However, it also has disadvantages, such as: thibenzone is slow to act, especially at low temperatures, so it is not recommended to use it when the daily average temperature is lower than 21°C

Among all the harvesting aids, Thidiazuron requires the longest time without rain after spraying (24h), indicating that its absorption is slow
