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
60 g / L Tebuconazole Compound Seed Coating Agent (produced by Shandong United Pesticide Industry Co., Ltd., registration number PD20098358), used to prevent and control wheat and corn viruses, but there is no report on the prevention and treatment of cotton diseases
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; the duration of the above three seed coating agents can control the occurrence of cotton blight or cotton aphids, but they cannot both , the control effect of other seed coating agents on cotton blight or cotton seedling aphids is not as good as the above three agents

Embodiment 1

[0032] Examples 1 to 6 are specific implementations of the compound seed coating agent containing pyraclostrobin, tebuconazole and dinotefuran and its application according to the present invention, of which Example 1 is the best example. The composition ratio of the stainless sand in Examples 1-6 is shown in Table 1. In the preparation method, the equipment used for shearing is a shear mixer, and the equipment used for grinding is a grinder. The preparation raw materials used in Examples 1-6 are 98% pyraclostrobin original drug and 98% tebuconazole original drug. YUS-207K dispersant is produced by Takemoto, Japan.

Abstract

The invention discloses a compound seed coating agent containing pyraclostrobin, tebuconazole and dinotefuran, and an application thereof, and belongs to the technical field of pesticides. According to the compound seed coating agent, pyraclostrobin is a mitochondrion respiration inhibitor, tebuconazole is capable of inhibiting the biosynthesis of ergosterol of fungi, the two single pesticides have different action mechanisms, and have a synergistic effect and are capable of inhibiting the resistance growth of cotton rhizoctonia solani with regard to the two bactericides and expanding the prevention and treatment range of the compound preparation after being mixed; and dinotefuran is the third-generation chloronicotinyl insecticide, and is superior to the traditional chloronicotinyl insecticides of imidacloprid and the like in prevention and treatment effect and lasting period for the pests of cotton aphid, plant hopper, leafhopper, thrips, whitefly and the like due to different structures, the three bactericides all have the characteristic of long lasting period, and are suitable for being used as effective components of the seed coating agent, and the compound seed coating agent is capable of controlling the cotton aphid and damping-off in the seeding stage of cotton during seed dressing, realizing the purposes of carrying out seed dressing in one process and treating both diseases and pests, and greatly reducing the pesticide usage amount and the prevention and treatment cost for the diseases and pests in the seeding stage of cotton.

Description

technical field [0001] The invention relates to a compound seed coating agent containing pyraclostrobin, tebuconazole and dinotefuran and an application thereof, belonging to the technical field of pesticides. Background technique [0002] Pyraclostrobin is a new type of broad-spectrum fungicide with a long duration of action. The mechanism of action is a mitochondrial respiration inhibitor, which has the functions of protection, treatment and leaf penetration. Tebuconazole is a high-efficiency, broad-spectrum, systemic triazole fungicide with three functions of protection, treatment and eradication. It has a wide bactericidal spectrum and long-lasting effect. Conazole can inhibit the biosynthesis of ergosterol in fungi. Dinotefuran (dinotefuran) is a third-generation neonicotinoid insecticide. 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 c...
