-
摘要: 2013年在水稻进入穗期以后,部分稻田黑尾叶蝉聚集穗部危害,严重的出现了“黑穗”现象。据初步调查与田间试验,受害稻谷粒质量比健穗粒质量下降5%~11%,并随“黑穗”程度的加重损失增加;呋虫胺、烯啶·噻嗪酮、烯啶虫胺、噻虫嗪和吡虫啉等药剂可用于对黑尾叶蝉的田间防治。Abstract: After the rice into the heading in 2013,Nephotettix cincticeps(Uhier)gathered harm together on the rice ears in part of the rice fields,and the serious phenomenon was‘black ears’.According to preliminary investigation and field experiment,results showed that the rice grain weight reduced by 5%~10% than the healthy-ear grain,and with the‘black’degree aggravating loss increases.Dinotefuran,Nitenpyram-Buprofezin,Nitenpyram,Thiamethoxam and Imidacloprid could be used to control the rice leafhoppers.
