Compounded seed coating agent containing pyraclostrobin, thifluzamide and dinotefuran and application

Abstract

The invention discloses a compounded seed coating agent containing pyraclostrobin, thifluzamide and dinotefuran and application, and belongs to the technical field of pesticide. The pyraclostrobin is a strobilurin fungicide, the thifluzamide is a thifluzamide fungicide, the objects and the ranges of control diseases are different, and if the pyraclostrobin and the thifluzamide are mixed and matched, the synergism effect is achieved, resistance increasing of cotton rhizoctonia to the two fungicides can also be inhibited, and the control range of a compounded preparation is enlarged; the dinotefuran is a third-generation chloronicotinyl insecticide, as the structure is different, the control effect and the lasting period on pests such as cotton aphids, plant hoppers, leafhoppers, thrips and whiteflies are better than the control effect and the lasting period of a traditional chloronicotinyl insecticide such as imidacloprid; the pyraclostrobin, the thifluzamide and the dinotefuran have the advantage of being long in lasting period and are suitable for serving as effective constituents of the seed coating agent, cotton aphids and damping off in the cotton seeding stage can be controlled when seeds are stirred with the compounded seed coating agent, the aim that diseases and pests are controlled through once seed stirring is achieved, and meanwhile the pesticide using amount and the control cost for diseases and pests in the cotton seeding stage are greatly reduced.

Description

technical field [0001] The compound seed coating agent containing pyraclostrobin, thifluzamide and dinotefuran and its application belong to the technical field of pesticides. Background technique [0002] Dinotefuran (dinotefuran) is a third-generation neonicotinoid insecticide, and its control effect and duration are better than those of imidacloprid and other second-generation neonicotinoid insecticides. Dinotefuran is very safe for mammals. It can control aphids, planthoppers, leafhoppers, thrips, whiteflies and their resistant strains on wheat, rice, vegetables, cotton, fruit trees and other crops. Thiofuramide, also known as tifluzamide, belongs to the thiazole amide fungicides, with strong systemic conductivity and long-lasting effect; Thiofuramide is effective against Rhizoctonia, Puccinia, Pathogenic fungi such as Powdery mildew, Pleurophora, and Sclerotinia are active, especially for diseases caused by Basidiomycetes, such as sheath blight and damping-off. Pyracl...

Problems solved by technology

[0005] First of all, in the existing technology, cotton aphids need to be sprayed 3 to 7 times by spraying at the seedling stage. The amount of pesticide used is large, the workload is heavy, and the cost is high, and a large amount of pesticides seep into the ground during the spraying process, resulting in environmental pollution

Secondly, the existing seed coating agent has an unsatisfactory control effect on cotton blight, and the dosage is large and the control effect is poor. In the prior art: pyraclostrobin compound seed coating agent is used to prevent and control cotton blight, damping sick

240 g / L Thiofuramide Suspending Concentrate (Shandong Zhaofengnian Biotechnology Co., Ltd., registration number PD20151827), used to prevent and control wheat and corn viruses, but there is no report on the prevention and treatment of cotton viruses

Thirdly, the control effect of existing seed coating agents on cotton aphids is not ideal. In the prior art, 60% dinotefuran seed treatment dispersible powder (produced by Anhui Fengle Agrochemical Co., Ltd., registration number LS20160047) is used to prevent and control wheat aphids. Aphids, leafhoppers, and planthoppers on various crops such as rice, cotton, vegetables, fruit trees, and tobacco leaves
