Problems solved by technology

[0009] With the long-term and extensive use of these selective fungicides with a single mechanism of action, drug resistance has emerged in the natural pathogenic fungal population, and the use effect has declined year by year
Through nearly 30 years of drug resistance monitoring, the inventor found that Fusarium fungi resistant to carbendazim and other benzimidazole fungicides in East China have formed a dominant group, and commonly used benzimidazoles such as carbendazim and thiophanate Fungicid

Embodiment 1

[0129] Embodiment 1: 42% agricultural fungicide suspension concentrate of the present invention controls wheat disease test

[0130] Test time and place: April 2015, Jiangsu Xinyang Farm

[0131] Test material: wheat, variety: Huaimai No. 33.

[0132] experiment method:

[0133] Sample preparation method: mix epoxiconazole and Jinggangmycin original drug according to the weight ratio of 1:20, 1:6, 5:16, 5:2 and 6:1, and then process according to the research V method described in the instruction manual of this application to obtain 42% different proportions of agricultural fungicide suspension test samples. Use 25 milliliters, 50 milliliters, 100 milliliters of composition preparations per mu. Spray with water in the early stage of wheat flowering, spray the second medicine every 5 days, and spray 50 kg of water per mu. At the same time, the corresponding dose of wettable powder single agent and sprayed water were used as the control, and carbendazim was used as the contro...

Embodiment 2

[0139] Embodiment 2: 64% agricultural fungicide suspending agent wettable powder of the present invention prevents and treats wheat disease test

[0140] Test time and place: April 2015, Jiangsu Yanjiang Agricultural Science Institute (Rugao)

[0141] Test material: wheat. Variety: Yangmai No.4.

[0142] Test method: Mix epoxiconazole and Jinggangmycin at a weight ratio of 1:1, and prepare a 64% wettable powder test sample according to the method of research VII described in the specification of this application. Wettable powders containing 4-20 grams of active ingredients of Jinggangmycin and epoxiconazole were used for each mu. Spray water at the early flowering stage of Yangmai No. 4 wheat, and spray the second medicine every 5 days, with a water spray volume of 45 kg per mu. Use the dosage of 20% single agent wettable powder in mixed use and spray clear water as contrast, set 50% polyketone wettable powder 60 g / mu as contrast agent. Each treatment was repeated 3 times,...

Embodiment 3

[0147] Embodiment 3: 20% agricultural fungicide wettable powder of the present invention prevents and treats wheat diseases and reduces toxin pollution test

[0148] Test time and place: In April 2015, Jiangsu Yanjiang Agricultural Science Institute (Rugao), the test was arranged in the same field as Example 2.

[0149] Test material: wheat. Variety: Yangmai No.4.

[0150] Test method: After mixing epoxiconazole and Jinggangmycin original drug at a weight ratio of 1:1, add 10% kaolin carrier by weight, 2% sodium lignosulfonate additive, 2% carboxymethyl cellulose, 1% Alkylphenol polyoxyethylene ether phosphate and 2% polyvinyl alcohol, and finally add light calcium carbonate carrier to 100%, pulverize through a sand mill and pass through a 300-mesh sieve. A sample for the experiment of the agricultural fungicide wettable powder of the present invention with a content of 20% was prepared. Wettable powders containing 20, 15, and 6 grams of active ingredients of Jinggangmycin ...

Abstract

The invention relates to a pesticide composition used for preventing and treating wheat head blight. The pesticide composition is prepared from the following components in parts by weight: 1-150 parts of validamycin and 1-20 parts of epoxiconazole. The pesticide composition provided by the invention has a remarkable synergistic effect when used for preventing and treating wheat head blight, the effect of preventing and treating head blight can be remarkably improved, and the capability of preventing and controlling wheat head blight of human beings is improved; the pollution level of DON toxins of grains is remarkably reduced, the chemical consumption is reduced, the cost is reduced, the environmental pollution and the pesticide residue are reduced, the pesticide resistance on epoxiconazole of wheat pathogenic fungi is delayed, and wheat head blight is prevented and treated; the lasting period of validamycin is prolonged, the frequency of pesticide application is reduced, wheat powdery mildew, rust disease, leaf blight and banded sclerotial blight can also be treated, the use cost of pesticides is reduced, the use dosage of chemical pesticides is greatly reduced and the epoxiconazole-containing pesticide composition is environmentally friendly.

Description

[0001] The present invention takes the priority of the Chinese invention patent application CN201610244423.7 submitted on April 19, 2016. 【Technical field】 [0002] The invention belongs to the technical field of pesticides. More specifically, the present invention relates to a pesticide composition for preventing and treating wheat head blight, and also relates to the use of the pesticide composition. 【Background technique】 [0003] Wheat and barley are the most important cultivated cereal crops in the world and one of the main food crops in China. Cereal crops are often threatened by fungal diseases such as scab, powdery mildew, sheath blight, rust and leaf blight. These diseases occur in the cereal growing areas of the world, seriously affecting the yield and quality of cereal agricultural products, especially the wheat head blight caused by Fusarium can not only cause devastating yield loss, but also in infected grains Produces toxins such as deoxynivalenol (Trichothec...
