依据茶毛虫幼虫四龄前有规律地分布在茶丛两侧中下部叶片背面,并在20多天内,其垂直和水平活动范围保持相对稳定的特点,设计了茶毛虫低位侧向快速喷药防治技术。本文着重报道利用低位侧向快速防治技术大田喷施茶毛虫NPV毒力稳定性测定和大田单用NPV及其与农药混用的试验结果。 Based on the fact that the larvae of the larvae were regularly distributed on the back of the middle and lower leaves on both sides of the tea clump before the 4th instar and the vertical and horizontal activity range remained relatively stable within 20 days, technology. This article focuses on the use of low-speed side-by-side rapid control technology in the field spraying tea coccidian NPV virulence stability test and single field NPV and its mixed with pesticides test results.
