Abstract:

In rice production, the problem of insecticide resistance of Chilo suppressalis has become more and more serious, and the damage has increased year by year. Lumivia is a suspension seed treatment agent, which can be used as a rice border, its active ingredient is 50% chlorantraniliprole, which is mainly used to control Chilo suppressalis. In order to explore the rational and safe use of the pesticide and achieve the control effect, a field experiment of Lumivia seed coating treatment on rice germination, seedling emergence, the quality of the rice seedlings and the control effect of Chilo suppressalis were carried out, at the same time, field demonstrations were conducted. The results showed that Lumivia was a safe seed coating agent, which could be treated with dry grain or bud grain without affecting the elongation of seed buds, seed rooting and seedling quality. Seed dressing of Lumivia is labor-saving and efficient. It could reduce the number of times of applying medicine at least once during the tillering stage of rice （from sowing to 60 days after sowing）, and didn’t increase the occurrence of withered sheaths and cores of rice, and showed significant resistance to leaf roller borer.

摘要：

水稻生产中，二化螟的抗药性问题日益突出，为害逐年加重。路明卫是一种防治水稻螟虫的悬浮种子处理剂，其主要成分是50%氯虫苯甲酰胺。为合理安全使用该农药，达到预期防治效果，开展了路明卫种子包衣处理对水稻发芽、出苗、秧苗素质以及二化螟防效的田间试验，同时进行了田间示范验证。结果表明，路明卫安全可靠，用其（10 mL/667 m²）处理干谷或芽谷，不影响种芽的伸长、种子发根和秧苗素质；且省工高效，用路明卫拌种后可减少水稻分蘖期间（播种至播后60 d）1次二化螟农药防治，不增加水稻枯鞘、枯心的发生，还表现出显著的抗卷叶螟优势。
