摘要
研究了0.6%苦参碱水剂防治茶尺蠖(Ectropis oblique hypulina Wehrli)的田间效果。结果表明,在茶园病虫防治时,推荐使用0.6%苦参碱水剂600倍稀释液(1 125.00 m L/hm^2),在茶尺蠖1~2龄幼虫期每公顷对水675 kg于傍晚均匀喷雾到茶树全株,既节约成本,又达到最佳防效。
The field effect of 0.6% soluble matrine formulation on Ectropis obliqua hypulina Wehrliwas was observed. Results showed that,for E. oblique management,it was recommended to use 0.6% matrine as 600 times diluentsolution （1125.00 mL/hm2） with 675 kg water per hectare and spray to tea plants evenly in the evening when tea geometrid was 1~2 instars, which resulted in both low cost and the optimum high control effect.
