Wheat powdery mildew is a worldwide disease, and it is distributed in all major wheat producing countries. China's Shandong coast, Sichuan, Guizhou, and Yunnan are widespread and the damage is heavy. In recent years, the disease has become increasingly serious in the northeast, north, and northwestern wheat regions. Specific prevention measures are as follows:
First, reasonable field management measures. Reasonable dense planting, precision semi-precision sowing, appropriate late sowing, improve plant disease resistance; pay attention to the rational use of nitrogen fertilizer, formula fertilization, timely drainage and irrigation.
Second, biological control. Can choose 1 billion CFU Bacillus subtilis 1000-1500 times the liquid, even before the onset of the disease or the early stages of the foliar spray, according to crop growth and disease severity, appropriate increase or decrease the amount of drug, depending on the disease prevention and treatment 2-3 times, the control effect is significant.

Fourth, in the wheat growing season, spraying 200 kg/ml paclobutrazol solution per acre 30 kg, can make the plant dwarf, increase lodging resistance, and can also treat wheat powdery mildew, improve the plant's absorption and utilization of nitrogen.
Fifth, wheat earing and heading stage, when the diseased plant rate reaches 15%-30% or the diseased leaf rate reaches 8%-15%, 15% triadimefon wettable powder 50g or 20% triadimefon emulsifiable concentrate 40g/mu can be used per acre. 10 kilograms of water is sprayed, and the disease can be controlled by 1 control.
