摘要
对陕北黄土地区仁用杏主要病虫害进行了无公害防治对比试验。结果表明:用自制石硫合剂防治杏疔病、杏褐腐病和杏球坚蚧效果好,成本低;用灭幼脲Ⅲ号防治卷叶蛾和桃小食心虫效果显著,用药后15 d平均防治率为97.8%;用1.8%阿维菌素防治金龟子、桃蚜和杏仁蜂,防效可达97.6%。
The non-pollution control of main diseases and pests of almond-apricot in the loess region of North Shaanxi was studied. The results showed that the control effects of self-made lime sulphur on boil disease, brown rot disease and Sphaerolecanium prunastri were good and the costs were low. The effects of diehlorbenzaron Ⅲ on leaf roller and peach fruit borer were obvious, and the average control efficiency was 97.8%. The control efficiency of 1.8% avermectin on scarab, peach aphid and almond bee reached 97.6%.
