摘要
使用高效、低毒、低残留农药防治害螨对于茶叶生产十分重要.在泸州市纳溪区选择不同树龄的3个茶园进行喹螨醚防效试验.结果表明:每667m2用200g/L喹螨醚SC 33mL及10%喹螨醚EC 67mL对茶叶害螨均有良好的防效,施药后3,7,14,21d前者防效分别达到70.56%,79.00%,78.59%,87.20%,后者分别为64.08%,80.39%,77.93%,88.14%,均显著优于目前我区茶叶生产上使用的主要药剂73%炔螨特EC.同时,喹螨醚具有触杀和胃毒双重功效,药效时间较长,不但能杀死幼若螨、成螨,还可直接杀死螨卵,是一个防治茶叶害螨较理想的新药.
With efficiency, low toxicity and residual pesticide to prevent against mites for tea production are very important. Field efficacy of Fenazaquin has been studied in 3 tea gardens of different tree age on the Naxi District, Luzhou City. e results indicate that every 667 m2 with 200g/L Fenazaquin SC 33 mL or 10% Fenazaquin EC 67 mL to prevent against mites to all had goodly control efficacy, the former control effect differentially are 70.56%, 79.00%, 78.59%, 87.20% and latter 64.08%, 80.39%, 77.93%, 88. 14% after applying pesticide 3, 7, 14 and 21 day, besides, are significantly better than 73% Propargite EC which is the main drug for tea production on the Naxi District.
