Problems solved by technology

[0003] At present, there are many kinds of defoliants, mainly including thiadiuron, defophos, glyphosate, paraquat, diuron, shedding treasure, etc., which accelerate the leaf shedding by inducing the formation of petiole detachment layer, but the spraying concentration is too high Or improper spraying time will seriously affect the yield and fiber quality of cotton, and there is no compound that can both defoliate and ripen

Embodiment 1

[0030] Example 1: 25% water dispersible granules

[0031] Formula (weight ratio): Thidiazuron 5%, Diquat 10%, Methionine 10%, Sodium Lauryl Sulfate 10%, SP-2836 Polycarboxylate Dispersant 5%, Sodium Sulfate 2%, Kaolin 20 %, diatomaceous earth makes up 100%.

[0032] Preparation method: firstly dilute methionine with warm water, then add thiadidiuron and diquat in turn to obtain a mixed solution, then add additives, pulverize through a jet mill and granulate to obtain water-dispersible granules.

Embodiment 2

[0033] Embodiment 2: 42% water suspension concentrate

[0034] Formula (weight ratio): thiadizuron 10%, diquat 12%, methionine 20%, fatty alcohol polyoxyethylene ether 5%, dispersant NNO 10%, ethylene glycol 2%, xanthan gum 1%, water Make up 100%.

[0035] Preparation method: first dilute methionine with warm water, then add thiadizuron and diquat in sequence to prepare a mixed solution, then add auxiliary fatty alcohol polyoxyethylene ether, dispersant NNO and ethylene glycol, grind and mix with xanthan Glue mixing, high-speed shearing and mixing to obtain a water-suspended dosage form.

Embodiment 3

[0036] Example 3: 35% dispersible oil suspension concentrate

[0037] Formula (weight ratio): Thidiazuron 15%, Diquat 8%, Methionine 12%, YUS-110 Emulsifier 15%, Sodium Lignosulfonate 8%, Ethylene Glycol 2%, Xanthan Gum 1%, Epoxidized soybean oil 2%, silicone oil 1%, vegetable oil (soybean oil) supplemented to 100%.

[0038] Preparation method: After mixing the raw materials, high-speed shearing disperses, and then sanding with a sand mill to obtain a dispersible oil suspension formulation.

Abstract

The invention discloses a compound synergetic defoliation ripening agent and application thereof. An effective ingredient of the defoliation ripening agent is prepared by compounding thidiazuron, diquat and methionine. The compound synergetic defoliation ripening agent has the advantages that besides good defoliation and maturity, the content of leafy chip in cotton is reduced and the quality andthe efficiency of mechanized cotton mining operation are improved; in addition, the yield of the cotton is improved and the pesticide use cost is reduced; the compound synergetic defoliation ripeningagent has no adverse effects on the quality of cotton fibers.

Description

technical field [0001] The invention relates to but not limited to the technical field of pesticides, and relates to a compound synergistic defoliation ripening agent and application thereof. Background technique [0002] In recent years, the mechanized planting and processing of cotton has been popularized and applied on a large scale, while the development of mechanized cotton picking is relatively slow, which has become the main factor restricting the development of the national cotton industry. Cotton harvesting requires a lot of manpower and material resources. Especially in recent years, the rural labor force structure is changing, labor is in short supply, and the cost of manual cotton harvesting is increasing year by year. Therefore, the realization of cotton mechanical harvesting is the future development direction. However, mechanical harvesting has higher requirements on the defoliation rate and boll opening of cotton. In order to increase the yield and variety of...
