Cotton defoliant

Abstract

The invention discloses a cotton defoliant, which is formed by mixing of the following components by weight: 40-50 parts of ethephon, 20-40 parts of pyraflufen-ethyl, 2-4 parts of hydroxyquinoline, 1-3 parts of carrageenan, 6-8 parts of chlorate, and 10-20 parts of water. The product provided by the invention has the characteristics of small particle, high surface activity, strong penetration, no dust during dispensing, low cost, high efficacy, cold protection and frost resistance, etc., increases the yield and improves the level, and is an ideal drug for mechanical harvesting and artificial rapid harvesting.

Description

technical field [0001] The invention relates to a pesticide, in particular to a cotton defoliant. Background technique [0002] As one of the main economic crops, cotton is planted in a wide range in my country, and the production of cotton is closely related to people's daily life. Therefore, increasing cotton production and improving cotton quality are of great significance to the development of my country's light textile industry and the improvement of people's living standards. The unlimited growth habit of cotton and the decline in ambient temperature in the late growth period often lead to the formation of later peripheral bolls and upper bolls that cannot Normal boll opening is mature, so that the yield and fiber quality are affected. 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 for the leaves re...
