| 摘 要： | 稻飞虱是宁乡市水稻生产的主要害虫之一,化学防治目前仍然是防治稻飞虱最常用的方法。为了掌握常用化学农药对田间稻飞虱的相对防效,延缓和避免稻飞虱对常用农药产生抗药性,通过田间试验研究了目前市场上几种常用化学农药对稻飞虱的防治效果。结果表明:呋虫胺、烯啶虫胺、毒死蜱、敌敌畏和吡蚜酮对稻飞虱的速效性较好;噻虫嗪、呋虫胺、吡蚜酮和氟啶虫酰胺对稻飞虱的持效性较好;而呋虫胺和吡蚜酮对稻飞虱既有较强的速效性又有较好的持效性,值得在宁乡市推广使用。

| Abstract: | Rice planthopper is one of the main pests in rice production in Ningxiang, chemical control is still the most common method. To command the control effect that the use of chemical pesticides acting on Rice planthopper, delay and avoid the rise of the resistance to the common pesticides, field experiments were carried out to study the control effect which several commonly used chemical pesticides are on the market at present. The results showed that the dinotefuran, nitenpyram, chlorpyrifos, dichlorvos and pymetrozine have good quick availability, thiamethoxam, dinotefuran, pymetrozine and flonicamid poss good durable effect, while dinotefuran and pymetrozin share both, which is worth popularizing in Ningxiang. |
