A kind of cotton defoliant

Abstract

The invention discloses a cotton defoliation agent. It belongs to the technical field of pesticides. The defoliant comprises the following components in parts by mass: 20-30 parts of cyclopropanamide, 30-50 parts of fomesafen, 10-15 parts of glyphosate and 10-15 parts of sodium bicarbonate. Compared with the prior art, the beneficial effects obtained by the present invention are as follows: the composition of the present invention exhibits a synergistic effect, and the defoliation effect is far better than that of using a certain component alone; it can promote cotton defoliation, accelerate cotton boll opening, Improve cotton yield without affecting cotton quality; good activity and defoliation effect can still be maintained in an environment lower than 20°C; less dosage will not pollute the environment.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a cotton defoliation agent. Background technique [0002] Cotton is an important economic crop. It can be made into fabrics of various specifications and can also be used to extract edible oil. It plays an important role in my country's agricultural economic pattern. However, in recent years, the shortage of labor resources and the sharp increase in labor costs have significantly reduced the economic benefits of cotton. In order to reduce costs and improve the benefits of cotton planting, it is an inevitable choice for the development of the cotton industry to realize fully mechanized cotton picking. Defoliation and accelerated ripening is an important prerequisite for mechanical cotton picking. Defoliation and ripening mainly uses plant growth regulators to intervene in the physiological and biochemical processes of cotton, accelerate plant aging, and achieve defoliation. ...

AI Technical Summary

Problems solved by technology

However, the cost of thiadizuron is higher, and the defoliation speed is slower, and the ability to withstand low temperature is poor

The effect of ethephon on ripening is good, but the effect of defoliation is poor, which in turn affects the impact of mechanical harvesting on cotton quality
