Embodiment 1

[0010] Example 1: 55% Cyanoprostrobin·Benthiamid Water Dispersible Granules

[0011] 5g of cyanobacteryl, 50g of fenthioprine, 4g of sodium lauryl sulfate, 2g of sodium lignosulfonate, 4g of ammonium sulfate, 2g of gum arabic, and kaolin to make up to 100g to obtain 55% cyanobacteryl benzene Thiapyrim water dispersible granules.

Embodiment 2

[0012] Example 2: 55% Cyanoprostrobin·Benthiamid Water Dispersible Granules

[0013] 50g of cyanobacteryl, 5g of benthiyl, 4g of sodium lauryl sulfate, 2g of sodium lignosulfonate, 4g of ammonium sulfate, 2g of gum arabic, and kaolin to make up to 100g to obtain 55% cyanobacteryl benzene Thiapyrim water dispersible granules.

[0014] According to the formulas of Examples 1 and 2, the active ingredients, auxiliary agents and fillers are mixed, and after stirring evenly, the master powder is obtained by pulverizing, and the master powder and the binder are mixed uniformly, and then granulated, dried and sieved, that is, It can be used to prepare cyanobacteryl·benthiamid water dispersible granules.

Embodiment 3

[0015] Example 3 : 50% Cyanostrobin and Benthiamid WP

[0016] 25g of cyanobacteryl, 25g of Benthiamid, 4g of sodium lauryl sulfate, 4g of sodium lignosulfonate, and kaolin make up 100g. The 50% cyenostrobin·benthiamid wettable powder was prepared.

Abstract

The invention discloses a fungicide composition containing cyprostrobin and benthiazil, which belongs to the technical field of pesticides. The weight ratio of the two components based on the active component is 1:10-10:1. Its ingredients also contain additives and fillers, of which cyclostrobin and benthiazil account for 5%-60% of the total weight of the fungicide, additives account for 5%-30% of the total weight of the fungicide, and the rest are fillers . The fungicide of the invention has been tested in practice and has remarkable control effect on wheat scab. Compared with conventional wheat scab fungicides, the compound fungicide of the present invention has the following advantages: compared with a single agent, the variety has obvious synergistic effect on wheat scab, and can significantly improve the control effect; Toxic fungicides can reduce dosage, reduce environmental pollution and residues of agricultural products; it can delay the resistance of wheat head blight to a single fungicide, and has the advantage of long-lasting effect. Compared with a single agent, it can reduce the cost.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a fungicide for preventing and treating wheat scab. Background technique [0002] Wheat head blight is a worldwide epidemic disease, which can lead to yield reduction, and mycotoxins remain in wheat, posing a huge threat to wheat production. The disease occurs seriously in the winter wheat region in the middle and lower reaches of the Yangtze River and the spring wheat region in Northeast China, where there is much rain at the heading stage and the climate is humid. It also occurs frequently in other wheat regions, causing great losses. Since the main varieties planted in large-scale production are susceptible or moderately resistant varieties, chemical control is still an important means to control head blight. In production, the main agents used to prevent and control the disease are benzimidazole and triazole fungicides, and drug resistance has emerged after years of use. ...
