鲜食玉米草地贪夜蛾绿色防控技术
Green Control Technology for Management of Spodoptera frugiperda on Fresh Corn
摘要
Abstract
Green control technology for management of Spodoptera frugiperda in the autumn fresh maize in Anhui province was explored through evaluation of the control efficiency,fresh ear yield,and yield increase rate in treatments at seedling,heart leaf and silking stages so as to reduce chemical use and recover yield loss.The results showed that the seedling emergence rate of seeds coated with 40%cyantraniliprole·thiamethoxam FS increased by 19.25%,and the control efficiency reached 74.48%at 14 d after seeding.When G033A microgranules were applied at the early whorl stage and 10%emamectin·chlorantraniliprole SC was applied at the late whorl stage,the control efficiency reached 90.62%at 21 d after treatment.The control efficiency of the combination of PS3 WP and 25%spinetoramWG(reduced by 20%)at the spinning stage reached 78.42%at 21 d after treatment.Compared with the farmers'self-control fields,chemical use was reduced by 4 times in the whole season,one of which was replaced by biological pesticides.The highest average grain weight per spike was 253.82g,representing a yield gain of 5.69%.The highest yield of fresh ear was 16243.70kg/hm2,representing a yield increase of 4.86%.Therefore,the green control technology for the fall armyworm in fresh corn in autumn is effective and safe,and can effectively reduce chemical use and increase yield.关键词
