Problems solved by technology

These products only have a single defoliating function, are used in large quantities, and are highly toxic to humans and animals, and are gradually being eliminated by the market
Thidiazuron, a new pollution-free, multi-target, slow defoliation agent, is becoming the main product for cotton defoliation, but Thidiazuron has the disadvantages of low ripening effect on cotton and slow defoliation speed

Embodiment 1

[0015] 35% fentrazone·thiadizuron SC;

[0016] Weigh 10g of the original drug of thiadiuron (calculated in hundreds, the same below), and 25g of mefentrazone, add the two original drugs into water, stir in a stirring tank to a homogeneous liquid, add dispersant (sodium lignosulfonate) 0.5 % ~ 10%, wetting agent (alkyl naphthalene sulfonate) 0.5% ~ 10%, after stirring evenly; under mechanical stirring at 60 ~ 120rpm / min, slowly add thickener (polyvinyl alcohol) 0.1% diluted with water ~5%, antifreeze agent (ethylene glycol) 0.1%~5%, defoamer (silicone oil) 0.01%~3%, make up to 100g with water, use air compression pipeline to transport material liquid during grinding, and use 4 sets of sand in series The mill (filled with fine zirconia beads and coarse zirconia beads) was sanded continuously to make 35% mefentrazone·thiadizuron SC (suspension concentrate).

Abstract

The invention relates to an efficient cotton defoliation method, particularly to an efficient cotton defoliation method using synergistically effective amounts of carfentrazone-ethyl and thidiazuron,wherein a weight ratio of carfentrazone-ethyl to thidiazuron can be changed within a wide range, and is most preferably 1:8.

Description

technical field [0001] The invention belongs to the field of agricultural growth regulators, and more specifically relates to a high-efficiency cotton defoliation method containing mefentrazone and thiadizuron. Background technique [0002] Cotton is the main economic crop in our country, with a wide planting area, and occupies an important position in the daily life of the people. According to incomplete statistics, in 2010, the national cotton planting area reached 85.35 million mu, and the total annual lint output was 6.32 million tons. According to the forecast of relevant parties, the domestic cotton gap will continue to expand. Vigorously developing cotton production and maintaining the basic position of domestic cotton in the demand for textiles is not only an objective requirement to give full play to the advantages of my country's cotton production country, but also an inevitable choice to improve the international competitiveness of my country's textiles. The com...
