大豆食心虫是大豆生产上的最主要害虫,每年因其危害造成了大豆质量与产量的严重下降。目前在防治大豆食心虫上虽有666、DDT 等化学防治方法,但因施药器械不足,施药时期不易掌握,特别是防治当时大豆已经封垅,作业困难,既影响了药效的充分发挥,也因防治时踩坏部分植株,造成人为损失,为此需要在施药方法上探索新途径。 Soybean moth worms are the most important pests in soybean production, causing a serious decline in the quality and yield of soybeans each year due to their damage. At present, there are 666 and DDT chemical prevention and control methods in the control of soybean beetle. However, due to the lack of facilities for application of pesticides, it is not easy to control the spraying period, especially when the soybean has been sealed and the operation is difficult. This not only affects the full play of efficacy, But also because of trampling some plants when trampled, resulting in human losses, this need to explore ways to apply new drugs.
