【摘要】 本研究在云南、四川、贵州、陕西、重庆5个省(市)共18个县市进行葡萄酸腐病、炭疽病和黑曲霉病害调查,调查发现,5省市葡萄酸腐病发生严重,在陕西省和重庆市部分地区发病率可达到35%以上;葡萄炭疽病发病率最高的地区是四川省成都市和重庆市璧山县,其发病率分别达到49.0%和45.0%,并且重庆市璧山县炭疽病的病情指数高达32.6;葡萄黑曲霉病发生普遍,陕西省西安市、四川省、重庆市发病率均高于20.0%,其中陕西省西安市发病率已达46.0%。5省市针对葡萄病害防治药剂主要集中在18种杀菌剂,主要防治葡萄炭疽病、白腐病、灰霉病和白粉病,酸腐病和黑曲霉病的防治技术比较缺失。通过调查,期望给当地提供合理的病害防控及药剂选择建议。更多还原

【Abstract】 Occurrence of grape sour rot, ripe rot and black Aspergilli was investigated in 18 counties and cities in Yunnan, Sichuan, Guizhou, Shaanxi and Chongqing. The results showed that sour rot occurred in five provinces(municipality), and the incidence rate in Shaanxi and Chongqing was over 35%. The highest incidence of grape ripe rot was 49.0% in Chengdu, Sichuan province, and 45.0% in Bishan, Chongqing city, and the disease index of grape ripe rot in Bishan, Chongqing municipality was as high as 32.6%. The occurrence of grape black Aspergilli was common, with the incidence of over 20% in Sichuan and Chongqing and 46.0% in Xi’an, Shaanxi. 18 kinds of fungicides have been applied to control grape diseases in five provinces(municipality), mainly including grape ripe rot, white rot, gray mold and powdery mildew, which the control technology for sour rot and black Aspergilli is relatively lacking. Through the survey, it is expected to provide reasonable suggestions for the prevention and control of disease and the choice of fungicides.更多还原
