Embodiment 1

[0023] Get 2.4 parts by weight of thiadizuron, 25 parts by weight of isoproturon and 15 parts by weight of ethephon, mix homogeneously, be mixed with the composition suspension that mass fraction is 42.4% (that is, in the composition suspension, thiadizuron accounts for 2.4 wt%, isoproturon accounts for 25wt%, and ethephon accounts for 15wt%).

Embodiment 2

[0025] Get 2.4 parts by weight of thiadidiuron, 50 parts by weight of isoproturon and 15 parts by weight of ethephon, mix homogeneously, be mixed with the composition suspension that mass fraction is 46% (that is, in the composition suspension, thiadizuron accounts for 2.4 wt%, isoproturon accounts for 50wt%, and ethephon accounts for 15wt%).

Embodiment 3

[0027] Get 7.2 parts by weight of thiadizuron, 25 parts by weight of isoproturon and 15 parts by weight of ethephon, mix homogeneously, be mixed with the composition suspension that mass fraction is 47.2% (that is, in the composition suspension, thiadizuron accounts for 7.2% wt%, isoproturon accounts for 25wt%, and ethephon accounts for 15wt%).

Abstract

The invention discloses a defoliating ripening composition, which comprises an active component A and an active component B. The active component A is a composition of thidiazuron and ethephon, the active component B is isoproturon, the mass ratio of the active component A to the active component B is (0.1-0.9): 1, and the mass ratio of the thidiazuron to the ethephon is (0.1-0.9): 1. The invention further discloses application of the cotton defoliating ripening composition. Test results show that the defoliating ripening composition can well promote cotton defoliating, accelerate cotton bollopening and increase the cotton yield, and the fiber quality of cotton is not affected.

Description

technical field [0001] The invention belongs to the technical field of pesticides, relates to the field of pesticide compositions and applications thereof, in particular to a cotton defoliation and ripening acceleration composition containing thiadidiuron and isoproturon and applications thereof. Background technique [0002] Spraying defoliants before cotton harvesting can promote the shedding of cotton leaves and concentrated boll opening, reduce the impurity content of cotton, and improve the efficiency of cotton mechanized harvesting operations. At present, there are 87 cotton defoliant products approved and registered in my country within the validity period, including 45 single agents and 42 mixed agents. The single agent is mainly thiadizuron, there are 43; the other 2 are metazachlor. The mixture is mainly thiadiuron·diuron, there are 40 of them, and the other two are thiadiuron·ethephon and diuron·thiadiuron·ethephon. Therefore, the active ingredients of cotton de...
