Hawthorn cultivation is one of the main industries of Shannan Zhangzhuang in Shanyin Village, Luquan District, and it has become an important source of income for farmers' household income. However, with the rapid development of the economic circle in Shijiazhuang, young people leave the rural areas to make money, leaving the elderly to become the chief manager of the hawthorn industry. Due to the weather this year, the occurrence of powdery mildew in mountain areas has increased and Zhang Xiying, a technical instructor, has found out that he has directed the villagers to take measures to prevent and control hawthorn powdery mildew. Hawthorn powdery mildew is also known as curved neck or face. The main damage leaves, shoots and fruits. The white leaves on both sides of the primary leaves of the diseased leaf were spotted. In severe cases, the white powder covered the entire leaf, and the surface grew black with small spots. The newly emerged infected pink diseased lesions, the late disease covered with white powder, the growth of new shoots weakened or internode shortening, the upper blade twisted and curled, severe withered. Young fruit infected with fruit surface covered with a layer of white powder, the diseased part of the hardened, cracked, leading to deformity; fruit damage in the near-mature period, resulting in red-brown lesions, rough surface. Powdery mildew reinfected by airflow. Warm and droughty springs and cool and rainy summers are easily endemic. Partial application of nitrogen fertilizer, planting too dense incidence. Seedlings are susceptible to disease. Prevention and control measures: First, plucking the tree trays in winter and spring, plowing the tree line, eradicating the self-generated roots, wild hawthorn trees, removing the leaves, diseased branches, fallen leaves, fruit drops under the trees, and burning or burying them together. Control the fertilizer and water, do not apply nitrogen fertilizer, do not make the garden soil excessive drought, reasonable sparse, sparse leaves. Second, the hawthorn sprouting leaves, you can spray protective agent, to prevent the incidence of disease infection, you can use l:2:240 times Bordeaux fluid, 50% of the special WP wettable (Fumei Shuang Fu Mei Zinc Fu Mei Jia Li) 500 to 800 times liquid, 80% anthrax fume wettable powder 600 times, 75% chlorothalonil wettable powder 800 times, 70% mancozeb wettable powder (Fumei Shuang Fu Mei Zinc) 600 to 800 times liquid, 65% Propylene Zinc Wettable Powder 600 to 800 times, 30% Basic Copper Sulphate Rubber Suspension 300 to 500 times, 53.8% Copper Hydroxide Suspension 800 times, evenly sprayed. Third, the early stage of hawthorn powdery mildew should be controlled in time, it is best to apply protective agents and therapeutic agents mixed to prevent the disease from further expansion. In the middle and late April (bud stage), late May (fruit setting period) and early June (young fruit period), spray 1 time, 70% Mancozeb WP can be used 600 to 800 times liquid + 20% Oxazolone EC 800 ~ 1 000 times, 75% chlorothalonil wettable powder 800 times liquid + l 2.5% diniconazole wettable powder 2000 times, 75% chlorothalonil wettable powder 800 times + 20% o-allylphenol wettable powder 1 000 times, 70% mancozeb wettable powder 600 to 800 times liquid 70% thiophanate-methyl wettable powder 500 times, 50% carbendazim Wet powder 600 times liquid + 65% dexamethasone wettable powder 500 times liquid, 75% chlorothalonil wettable powder 800 times liquid + 40% fluorosiliconazole cream 2 000 times liquid and so on. Fourth, when the disease is severe, one can use 15% triadimefon WP 600 times, 40% fluorosiliconazole EC 4000 to 6000 times, and 12.5% ​​diniconazole WP 1000 to 2000 times. 10% difenoconazole water dispersible granules 1500 to 3000 times, 5% hexaconazole suspension 800 to 1 500 times, 5% imidazole wettable powder 600 to 700 times, 25% propiconazole L000 times liquid, 25% chlordiazep EC 800 to 1 000 times evenly sprayed.
