| Abstract: | to evaluate the controlling effectiveness of Ruijinte and Avermectin B1 mixed application on Cnaphalocrocis medinalis, an experiment was conducted and the results showed that in larva peak period, 10ml, 15ml, 20ml, 25ml 5 %-Ruijinte mixed with 8ml, 12ml, 16ml, 20ml 1.8 %-Avermectin B1/ 667m^2 respectively were applied on controlling the pest and the controlling effectiveness could reach 85. 29% --98. 12%, among them, 25ml Ruijinte mixed with 20ml Avermectin B1 had the best result and 15ml Ruijinte mixed with 12ml Avermectin B1 had a lower cost and better effectiveness by 91.61%, which was 28.34 points higher than the application of 300ml 18 %-dimehypo （P 〈 0.05）and can be extended in large scale. |
