Abstract
The invention discloses a composition for preventing and treating soybean downy mildew. The composition for preventing and treating the soybean downy mildew is prepared from the following raw materials in parts by weight: 20 to 30 parts of chlorfenapyr, 10 to 20 parts of acorone, 130 to 150 parts of glycerin, 350 to 370 parts of water and 6 to 8 parts, in total, of butyl methacrylate and magnesiumsulfate which serve as synergists, wherein the ratio of the butyl methacrylate to the magnesiumsulfate, in parts by weight, is (5 to 7): 1. The composition provided by the invention can be used for preventing and treating the soybean downy mildew, and can be developed into a pesticide for preventing and treating the soybean downy mildew; prevention and treatment effects are relevant to the ratio of the butyl methacrylate to the magnesiumsulfate, which serve as the synergists, in parts by weigh, in the raw materials; when the ratio of the butyl methacrylate to the magnesium sulfate, in parts by weight, is (5 to 7): 1, the prevention and treatment effects are the best. Moreover, the composition provided by the invention is small in spraying volume, and is not easy in residing.
Description
technical field [0001] The invention belongs to the field of pesticides, in particular to a composition for preventing and treating soybean downy mildew and a preparation method thereof. Background technique [0002] Chlorfenapyr is a new type of pyrrole compound, which acts on the mitochondria of cells in insects, acts through multifunctional oxidases in insects, and mainly inhibits the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). Adenosine triphosphate stores the energy necessary for cells to maintain their vital functions. The drug has stomachtoxicity and contact action. It has strong permeability on the leaf surface, has a certain systemic effect, and has the characteristics of broad insecticidal spectrum, high control effect, long-lasting effect and safety. Resistant pests can be controlled. [0003] Soybean downy mildew is widely distributed in soybean producing areas of the world. It was first discovered in Northeast China in 1921. I...
