Funing County, a reader phone: This year's epidemic trend of wheat head blight, what drug control effect is good?
Jin Hengxing sent WeChat: I am a large farmer in Pei County. What medicine for wheat scab is effective, and when is the best?
Wang Shouming sent a micro-letter on April 6: I am a farmer in Anhui. I would like to ask what is the best medicine for the prevention and treatment of wheat scab.
According to the prediction of Jiangsu Plant Protection Station, in 2016, the predicted degree of wheat scab in the province is Grade 4; in South Jiangsu, along the river, in the Lixia River and along the Huaihua, there are 5 levels; in the Huainan region, it is 1 level higher than in 2015; if the wheat heads Rainy weather, high temperatures, high humidity, or hazy weather are numerous and the degree of occurrence will increase.
Fusarium head blight usually has the highest infection rate in wheat flowering to full flowering stage, followed by the heading period, and the infection rate of the milk during ripening period is obviously reduced. The bacteria can not be invaded after the ripening period. The best period for controlling wheat scab is early flowering (5% to 10% of the young plant), and the principle of applying “see flower to fight†can be mastered in the production. Wheat in the field begins to bloom and is used for drug control. Wheat heading, flowering and rainy days or varieties susceptible to disease, the first time after the application of pesticide control interval of 5 to 7 days. If the heading date of wheat is more than rainy, there is a prevalence of head blight, and the spraying of pesticides will sooner rather than later, and it will not be possible to wait until the weather is fine or when wheat is sprayed. Spraying should be repeated before rain or in the rain gap. The time of first application of pesticides with good suction and long duration can be advanced to the ear of wheat.
Applicable to the control of wheat scab disease drugs cyanoxuron, tebuconazole, carbendazim, thiophanate-methyl, prochloraz, nymphaclide and so on. In regions where fulvic acid produces a high level of resistance to carbendazim, cyanogenate, tebuconazole and other drugs and their mixtures should be used for prevention and control. From the perspective of production applications, a single dose of cyanocastrobin (Jinhuo) and its mixture with tebuconazole and hexaconazole, Jinxing 48% cyanene tebuconazole suspension, 20% cyanene Hexiconazole alcohol suspension, tebuconazole and carbendazim, prochloraz mixed agent carbazole carbendazim (Long Deng Fu Lian, etc.), temizole prochloraz (Zammer, etc.) and other drugs, is the prevention and treatment of wheat red Highly effective moldy mildew, adequate use of appropriate period of time has good control effect on wheat scab. These drugs can be used preferentially in production to control wheat scab. Pay attention to the amount of water in the foot and the amount of water and focus on evenly spraying the wheat ears.
