大蒜普遍发生且危害最为严重的当属根部虫害,根部害虫危害最猖獗。永年县每年大蒜种植15万余亩,由于连年重茬种植,大蒜虫害逐年加重,田块发生率达60-70%,导致大蒜减产30-40%,甚者达60%以上。是制约大蒜发展的一大因素,给当地蒜农造成了很大的经济损失。我们通过两年的探索实践,针对根部害虫的生物学特性及发生发展规律,对其采取综合防治的措施,使防治区蒜头虫 The most common occurrence of garlic and the most serious is undoubtedly the root pest, the most harmful root pests. Yongnian County, planting more than 150,000 acres of garlic each year, due to continuous cropping year after year, garlic pests increased year by year, the incidence of field reached 60-70%, resulting in 30-40% reduction in garlic, even more than 60%. Is a major factor constraining the development of garlic, causing great economic losses to local garlic farmers. Through two years of exploration and practice, we aimed at the biological characteristics of root pests and the occurrence and development of the law, to take comprehensive measures to prevent and control garlic
