甘薯麦蛾是为害甘薯的重要害虫,以往由于使用化学农药,致使害虫抗药性增强,同时也杀伤了天敌,并污染了甘薯和环境,为此,我们采用省农科院生物技术中心生产的生物农药天霸防治甘薯麦蛾。 防治甘薯麦蛾应用的是生物农药天霸粉剂800倍液,根据监测预报,在幼虫发生初期进行喷药,时间以下午4—5时为宜,用背负压缩式喷雾器进行喷雾,做到叶面、叶背喷雾均匀、周到,防止遗漏。
Sweet potato moth is an important insect pest damage to sweet potato, the past due to the use of chemical pesticides, resulting in enhanced pest resistance, but also kill the natural enemies, and polluted the sweet potato and the environment, for which we use the Provincial Academy of Agricultural Biotechnology Center production of biological Pesticide Tianba control sweet potatoes moths. Prevention and control of potato sweet potato moth application biological pesticide Tianba powder 800 times the liquid, according to the monitoring and forecasting, early larvae spraying, the time 4-5 pm is appropriate, with a compressed spray nebulizer, so foliar , Leaf spray back evenly, thoughtful, to prevent omissions.
