【摘要】 试验结果表明,棵棵无损5%颗粒剂对甘蔗害虫具有良好的防效和显著的增产增收效果。施1次该药对螟虫的防效是49.1%,绵蚜虫40.0%～97.7%,蓟马42.1%～62.5%;比CK增产10.1%,差异显著性达5%水平,效益增长8.6%。施两次药对螟虫的防效是51.4%,绵蚜虫80%～100%,蓟马45.6%～50.5%;比CK增产14.4%,差异显著性达1%水平,效益增长11.5%。与标准药剂呋喃丹3%颗粒剂相比,不管是施1次药还是两次药对螟虫的防效都差不多,对绵蚜虫和蓟马的防效则表现出较为明显的优势;对蔗茎产量施两次药较高,施1次药稍低,差异不显著。更多还原

【Abstract】 The experimental results showed that 5% Kekewusun was able to control effectively sugarcane pests and significantly increased yield.The control effects to sugarcane stem borer,Ceratovacuna lanigera Zehntner and Baliothrips serratus Kobus were respectively 49.1%,40.0%-97.7% and 42.1%-62.5%,and yield increased by 10.1%,profit increased by 8.6% after applying Kekewusun one time,and the control effects were respectively 51.4%,80%-100% and 45.6%-50.5%,and yield increased by 14.4%,profit increased by 11.5% after two time application.As a result,the control effects to Ceratovacuna lanigera Zehntner and Baliothrips serratus Kobus were superior to that of 3% Furadan.There were significant different for cane yield of 5% Kekewusun application in comparison with the treatment of 3% Furadan.更多还原
