Embodiment 1

[0054] Example 1: 60% water suspension

[0055] Formula (weight ratio): thidiazuron 20%, glyphosate 40%, dispersant NNO 10%, fatty alcohol polyoxyethylene ether 4%, ethylene glycol 2%, xanthan gum 1%, water supplement 100%.

[0056] Preparation method: firstly dilute glyphosate with water, then add thidiazuron to prepare a mixture, then add the auxiliary dispersant NNO, ethylene glycol and fatty alcohol polyoxyethylene ether, mix with xanthan gum after grinding, high-speed shear Cut and mix well to obtain water suspension form.

Embodiment 2

[0057] Example 2: 75% water dispersible granules

[0058] Formula (weight ratio): Thidiazuron 50%, Glyphosate 25%, Sodium Lauryl Sulfate 8%, SP-2836 Polycarboxylate Dispersant 5%, Sodium Sulfate 2%, Kaolin 10%, Diatom Soil make up 100%.

[0059] The preparation method: firstly dilute the glyphosate with water, then add thidiazuron to prepare a mixed solution, and then add the auxiliary agent, pulverize with a jet mill, and then granulate to obtain the water dispersible granule form.

Embodiment 3

[0060] Example 3: 55% dispersible oil suspension concentrate

[0061] Formula (weight ratio): thidiazuron 5%, increased glyphosate 50%, sodium lignosulfonate 10%, YUS-110 emulsifier 12%, ethylene glycol 3%, xanthan gum 1%, epoxy soybean oil 2%, silicone oil 1%, vegetable oil (soybean oil) make up to 100%.

[0062] Preparation method: weigh thidiazuron and glyphosate into a container, add emulsifier, dispersant and soybean oil, mix and disperse at high speed, then sand with a sand mill, and filter to obtain dispersible oil Suspended dosage form.

Abstract

The invention especially relates to a defoliation and ripening composition for cotton, and a defoliation and ripening agent for cotton, belonging to the technical field of pesticides. The defoliationand ripening composition is composed of, by weight, 0.1 to 80 parts of thidiazuron and 0.1 to 80 parts of glyphosine. The effective components of the defoliation and ripening composition in the invention include thidiazuron and glyphosine, and have obvious synergistic effect on defoliation and ripening of cotton through a variety of different action modes, and the effect of the composition is significantly better than the effect of single thidiazuron, single glyphosine, a thidiazuron-diuron preparation and the like; and the composition is effective in reducing the dosage of different reagentssuch as thidiazuron and capable of accelerating the process of ripening and defoliation and reducing production cost.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to a cotton defoliation and ripening composition and a cotton defoliation and ripening agent. Background technique [0002] Cotton is an important multi-purpose economic crop. It can be made into fabrics of various specifications, and edible oil can also be extracted through certain processes. Therefore, cotton plays an important role in my country's agricultural economy. [0003] Cotton has unlimited growth habit, but it is affected by weather conditions. When the frost comes every year, most cotton areas in my country still have many bolls that cannot finish spitting. In late autumn, some bolls cannot mature, and some become flowers after frost, resulting in the quality of cotton. Cannot be guaranteed. Nowadays, mechanical harvesting of cotton is the general trend. In order to ensure the quality of cotton during mechanical harvesting, cotton needs to be defoliated and ripened in a tim...
