Control Effect of 200 g/L Kangkuan~(TM) against Corn Borer(Ostrinia furnacalis G.)

[Objective] The aim was to study the control method and technology of Ostrinia furnacalis G..[Method] Maize variety Xindan 26 was taken as materials,and the control effects of different dosages of 200 g/L KangkuanTM spraying at bell stage against Ostrinia furnacalis G.were studied.[Result] The 200 g/L KangkuanTM spraying at 375 ml/hm2 had the best control effect against Ostrinia furnacalis G..The infestation plant rate was 7.34% after spraying for 30 days;the infestation straw rate and infestation corncob rate were 2.00% and 10.00% respectively after spraying for 50 days;and the yield of dry corn was 10 827.60 kg/hm2.[Conclusion] The research result provides theoretical basis for the production and application of 200 g/L KangkuanTM and the control of Ostrinia furnacalis G..
