为了明确5.2%阿维菌素·毒死蜱颗粒剂、0.5%阿维菌素颗粒剂、5%毒死蜱颗粒剂、3%辛硫磷颗粒剂分别撒施对当归麻口病的防治效果,进行了田间试验。结果表明,在移栽当归苗之前撒施4种颗粒剂,均可有效降低当归麻口病的病情指数,并最终提高当归的产量与品质。其中,5.2%阿维菌素·毒死蜱颗粒剂45.00 kg/hm~2处理对麻口病的防效最高,病指防效达78.08%,增产率为106.05%;防效居次为3%辛硫磷颗粒剂,病指防效达69.62%,增产率为123.39%。
In order to clarify the control effect of 5.2% abamectin-chlorpyrifos granules, 0.5% Abamectin granules, 5% chlorpyrifos granules and 3% test. The results showed that applying 4 kinds of granules before transplanting Angelica sinensis seedlings could effectively reduce the disease index of angelica mackii and eventually increase the yield and quality of Angelica sinensis. Among them, 5.2% abamectin · chlorpyrifos granules treated with 45.00 kg / hm ~ 2 had the highest control effect on Maikou disease, the disease index was 78.08% and the yield was 106.05%; the control effect was 3% Sulfur granules, disease means 69.62% control efficiency, yield was 123.39%.
