向日葵黄萎病是内蒙古地区向日葵生产中主要病害,并呈现发病面积逐年加大、病情加重的态势。2016年在内蒙古巴彦淖尔市临河区选用5个向日葵品种、4种抗重茬菌剂开展对向日葵黄萎病防治试验。结果表明:人工穴播法的防治效果显著高于机械沟施法;不同抗重茬菌剂的粉剂防治效果好于颗粒剂;在施入抗重茬菌剂后进行浇水处理的防治效果高达84.4%,而浇水后施入抗重茬菌剂的防效达73.9%;同时选用抗病品种SH363加抗重茬菌剂处理对黄萎病的防效达79.5%,而感病品种LD5009加抗重茬菌剂的防治效果仅为33.5%。因此,选用抗重茬菌剂的粉剂,采用人工穴播法,结合后续的灌水处理和选用抗病品种,能够显著提高抗重茬菌剂对向日葵黄萎病的防治效果,防治效果达79.5%以上。
Verticillium wilt is the main disease in the sunflower production in Inner Mongolia, and presents the situation that the disease area increases year by year and aggravates. In 2016, five sunflower cultivars and four anti-recurring agents were selected for the prevention and treatment of sunflower wilt in Linhe, Bayannur, Inner Mongolia. The results showed that the control effect of artificial hole-sowing method was significantly higher than that of mechanical furrow method. The control effect of different antibacterial agents was better than that of granule. The control effect of water-repellent treatment was 84.4% After watering, the anti-recurring fungicide was applied with the control efficiency of 73.9%. At the same time, the control effect of resistant variety SH363 plus anti-recurring agent was 79.5% on Verticillium wilt, while the susceptible variety LD5009 plus anti-recurring agent Control effect is only 33.5%. Therefore, the selection of anti-recurring agent powder, artificial breeder method, combined with the follow-up irrigation treatment and the selection of resistant varieties, can significantly improve the anti-recurring agents Verticillium wilt prevention and control effects of prevention and treatment of up to 79.5%.
