Embodiment 1

[0054] Embodiment 1: 60% water suspension concentrate

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

[0056] Preparation method: firstly dilute glyphosate with water, then add thidiazuron to obtain a mixed solution, then add auxiliary dispersant NNO, ethylene glycol and fatty alcohol polyoxyethylene ether, grind and mix with xanthan gum, high-speed shear Cut and mix to obtain the water suspension dosage 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] Preparation method: first dilute glyphosate with water, then add thidiazuron to obtain a mixed solution, then add additives, pulverize through a jet mill, and then granulate to obtain a water-dispersible granule dosage form.

Embodiment 3

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

[0061] Formula (weight ratio): Thidiazuron 5%, Glyphosate 50%, Sodium Lignosulfonate 10%, YUS-110 Emulsifier 12%, Ethylene Glycol 3%, Xanthan Gum 1%, Epoxidized Soybean Oil 2%, silicone oil 1%, and vegetable oil (soybean oil) to make up to 100%.

[0062] Preparation method: Weigh thiadizuron and glyphosate into a container, add emulsifier, dispersant and soybean oil, mix and disperse at high speed, then grind with a sand mill, filter to obtain dispersible oil Suspension 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 composition for accelerating the ripening of cotton defoliation and an agent for accelerating the ripening of cotton defoliation. Background technique [0002] Cotton is a multi-purpose important economic crop. It can be made into fabrics of various specifications and edible oil can be extracted through certain processes. Therefore, cotton plays an important role in my country's agricultural economic pattern. [0003] Cotton has an unlimited growth habit, but affected by weather conditions, when the dry frost comes every year, there are still many cotton bolls that cannot be opened in most cotton areas in my country. Cannot be guaranteed. Nowadays, mechanical harvesting of cotton is the trend of the times. In order to ensure the quality of cotton during machine harvesting, it is necessary to timely defoliate and accelerate the ripening of cotton. At present, the types of si...
