无人机防治马尾松毛虫药剂及剂量研究

Study on the UAV Aerial Spraying Pesticides and Dosages for Control of Dendrolimus punctaius

本文以大疆植保无人机(型号T30)为施药机具,以市售1%苦参碱水剂、2.5%溴氰菊酯乳油及尿素为防治药剂,研究了松毛虫不同施药剂量及不同药剂组合的防治效果。结果表明,若松毛虫的虫龄比较整齐,且为1~2龄的低龄幼虫时,苦参碱防治即可;若虫龄不齐或为高龄幼虫时,以1%苦参碱水剂+2.5%溴氰菊酯乳油组合防治为佳。试验结果可为松毛虫防治工作提供参考。

In this paper,a study was made on the effects of the commercial pesticides 1%matrine aqueous solution,2.5%deltamethrin emulsion and urea of different doses and combinations in controlling Dendrolimus punctaius using DJI Plant Protection Drone(Model T30)for aerial spray.The results showed that matrine could be applied to control the pest larvae at unified 1 and 2 instars.The pest at diversified instars and older larvae could be best controlled with combination of 1%matrine aqueous solution and 2.5%deltamethrin emulsion.The study could provide reference for the pest control.
