Embodiment 1

[0024] Example 1: Preparation method of 2% tefluthrin·clothianidin·pyraclostrobin granules.

[0025] Active ingredients by weight tefluthrin 0.5%, clothianidin 0.5%, pyraclostrobin 1%, light calcium 5%, carboxyethyl cellulose 2%, sodium lignosulfonate 3%, polyvinyl alcohol 0.5%, butadiene resin film former 3%, active red 4%, kaolin to 100%. Mix tefluthrin, clothianidin, and pyraclostrobin evenly and crush them with air flow, then put them into a closed blending kettle and mix evenly, granulate by coating method, and dry at 110°C-120°C until The water content of the granules is less than 3%, sieved, and the particle size ranges from 2000 μm to 4000 μm. After passing the inspection, the required granules can be obtained.

[0026] In order to better verify the actual application effect of the present invention, the field efficacy test of the granule of the present invention is illustrated below with examples.

Embodiment 2

[0027] Embodiment 2: Test of preventing and controlling corn pest disease.

[0028] Test agent: 2% tefluthrin·clothianidin·pyraclostrobin granules (tefluthrin 0.5%; clothianidin 0.5%; pyraclostrobin 1%).

[0029] Control agent 1: 0.5% tefluthrin granules.

[0030] Control agent 2: 50% clothianidin water-dispersible granule.

[0031] Control drug 3: 25% pyraclostrobin EC.

[0032] This test was carried out in Xincun, Renshan Town, Huidong County, Huizhou City, Guangdong Province. The treatment chemicals were applied before corn sowing. The test results are shown in Table 1.

[0033] Table 1. Field efficacy test results of 2% tefluthrin·clothianidin·pyraclostrobin granules for controlling corn pests.

[0034]

[0035] As can be seen from Table 1, the 2% tefluthrin · clothianidin · pyraclostrobin granule of the present invention has a control effect of 96.82% and 87.37% on corn cutworm and root rot, and the effect is obviously better than 0.5% Three single doses of tefluth...

Abstract

The invention relates to a tefluthrin, clothianidin and pyraclostrobin containing pesticide composition. The composition is prepared from the following components in percentage by weight: 0.01 to 10% of tefluthrin, 0.05 to 20% of clothianidin, 0.01 to 10% of pyraclostrobin, 5 to 50% of auxiliaries, and 20 to 95% of carriers. The pesticide composition is prepared into granules according to the existing pesticide preparation process and is sprayed to prevent and control maize cutworm and root rot. The pesticide composition has synergism or adding effect for cutworm and root rot, is wide in prevention and treatment scope, low in labor intensity, and low in energy consumption.

Description

technical field [0001] The invention belongs to a pesticide composition, in particular to a combination of tefluthrin, clothianidin and pyraclostrobin as active ingredients, which is used for preventing and treating corn cutworm and root rot. Background technique [0002] Corn cutworm and root rot are insect pests of corn with strong damage, high incidence, many times of control and wide occurrence area, resulting in reduced or even extinction of corn production. Generally, farmers need to control pests and diseases 2 to 3 times from corn sowing to corn harvesting, especially before corn sowing, they need to use a variety of single pesticides in combination, which may easily lead to medication errors or poor mixing ratios, resulting in poor results, high labor intensity, and resources. waste. [0003] The mixing of different pesticide varieties is a common method to prevent and control agricultural insect pests and expand the scope of control. Through the scientific combin...
