Cotton defoliant and preparation method thereof

Abstract

The invention discloses a cotton defoliant and a preparation method thereof. The cotton defoliant is prepared through mixing the following components in parts by weight: 35-45 parts of magnesium chlorate, 5-7 parts of thidiazuron, 3-5 parts of Dailon, 6-10 parts of 8-hydroxyquinoline, 1-3 parts of a 888 pesticide synergist, 5-15 parts of chlorate and 10-12 parts of calcium oxide. The cotton defoliant disclosed by the invention has the characteristics of being small in particles, large in active surface, high in osmotic force, free from dust during compounding, low in cost, high in drug effects, capable of preventing cold and freeze, and the like.

Description

technical field [0001] The invention relates to a pesticide, in particular to a cotton defoliant and a preparation method thereof. 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. The cotton defoliant provided by the invention has not only the function of physiological defoliation, but also the adjustment function of adjusting the opening degree of stomata on the leaf surface, which can...
