Defoliating agent for cotton

Abstract

The invention discloses a defoliating agent for cotton. The defoliating agent is prepared by mixing the following components by weight: 40 to 50 parts of ethephon, 6 to 8 parts of magnesium chlorate, 20 to 40 parts of hydroxyquinoline, 1 to 3 parts of a pesticide synergist, 2 to 4 parts of chlorate and 10 to 20 parts of water. The defoliating agent provided by the invention has the characteristics of a small particle size, a large active surface, great penetration force, no rising of dust during agent dispensing, low cost, high effect, cold-proof and anti-freezing performance, etc. The defoliating agent has advantages of both wettable powder and missible oil, can be wetted by water, has good suspensibility when diluted by water and can be directly made into spray liquid for usage. The defoliating agent can effectively prevent unfavorable-delayed senescence, promote blow-of-cotton of cotton bolls, increase the proportion of flowers before frost, boost yield and raise the grade of cotton, and is an ideal drug for mechanical harvesting and rapid manual 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 is of great significance to the development of my country's light textile industry and the improvement of people's living standards. [0003] 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 o...
