Embodiment 1

[0027] The preparation of the defoliant (A) in wettable powder dosage form, the preparation method is to fully mix benzisoabscisic acid, thiadizuron and auxiliary agents, and pulverize through a jet mill to obtain wettable powder dosage forms with different active ingredient contents Defoliant for machine-picked cotton. The purity of the original medicine of benzisoabscisic acid is 98%. Thididiuron used was purchased from Jiangsu Hormone Research Institute Co., Ltd., and the purity of the original drug was 98%. In this embodiment, sodium dodecylbenzenesulfonate (chemically pure), sodium lignosulfonate (chemically pure) and kaolin (4000 mesh) are selected as the additives. It should be noted that the percentages in the formulations described in this embodiment are all weight (mass) percentages.

[0028] Defoliant A-1: ​​the mass fraction of benzisoabscisic acid is 0.01%, the mass fraction of thidiazuron is 5%, the mass fraction of sodium dodecylbenzenesulfonate is 10%, the ma...

Embodiment 2

[0033] The preparation of the defoliant (B) in the form of water-dispersible granules, the preparation method is to fully mix benzisoabscisic acid, thiadizuron, and auxiliary agents, pulverize through a jet mill, granulate, dry, and sieve , to obtain a machine-harvested cotton defoliant in the form of water-dispersible granules. The purity of the original medicine of benzisoabscisic acid is 98%. Thididiuron used was purchased from Jiangsu Hormone Research Institute Co., Ltd., and the purity of the original drug was 98%. In this embodiment, the auxiliary agent is selected from sodium dodecylbenzenesulfonate (chemically pure), sodium lignosulfonate (chemically pure), sodium sulfate (chemically pure), sodium carboxymethylcellulose (chemically pure) ) and kaolin (4000 mesh). It should be noted that the percentages in the formulations described in this embodiment are all weight (mass) percentages.

Embodiment 3

[0039] The preparation of the defoliant (C) of water suspension dosage form, its preparation method is that benzisoabscisic acid, thiadizuron, and auxiliary agent are fully mixed, pulverized by jet mill and then ground, then mixed with xanthan gum, shearing, to obtain the machine-harvested cotton defoliant in the form of water suspension formulation. The purity of the original medicine of benzisoabscisic acid is 98%. Thididiuron used was purchased from Jiangsu Hormone Research Institute Co., Ltd., and the purity of the original drug was 98%. In this embodiment, the auxiliary agent is selected from pull-off powder BX (chemically pure), sodium lignosulfonate (chemically pure), ethylene glycol (chemically pure), Kathon (chemically pure), organic silicon defoamer (chemically pure) and kaolin (4000 mesh). It should be noted that the percentages in the formulations described in this embodiment are all weight (mass) percentages.

Abstract

The invention discloses a cotton defoliant compounded from iso-PhABA and thidiazuron. The defoliant comprises iso-PhABA and thidiazuron in the mass ratio being (0.01-30):(5-70). The dosage form of thedefoliant comprises (but not limited) wettable powder, water dispersible granules or a suspension concentrate. The components are compounded reasonably and show a certain synergistic function, so that the defoliant has an excellent defoliation effect and shows better ripening acceleration and boll opening effects, and the yield and quality of cotton can be improved. Meanwhile, the defoliant contains no herbicides and ethephon components, and soil environment pollution and residues caused by heavy use of chemical defoliants and ethephon are reduced.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulators, and relates to a defoliant, in particular to a compound of benzisoabscisic acid and thiadiuron as a defoliant for machine-picked cotton. The defoliant can be used to promote defoliation and / or opening of cotton before harvesting. Background technique [0002] Xinjiang is the center of cotton cultivation in my country. According to the published national cotton production data, the national cotton production in 2017 was about 5.486 million tons, of which the total output in Xinjiang was about 4.082 million tons, accounting for 74.4% of the country. In recent years, the labor cost of growing cotton in Xinjiang has been rising, so the machine-picked cotton planting model is being vigorously promoted due to its low price. However, a series of problems such as the decline in cotton grades and cotton sales prices have followed. [0003] The commodity rate of cotton is affected by man...
