| Abstract: | In order to select best pesticides to control Rice Scirpophaga incertulas （Walker）, a selection experiment was conducted and the results show that 150,200g/666.7m^2 added with 50 kg of water, 20% Awei EC＇s effectiveness can be 90.47% and 95.24% respectively, better than the controlled treatment, the same effectiveness as the Jinpentou WP of 100g/666.7m, so that 20 % Awei EC and Jinpentou are recommended. The recommended amount for 20% Awei EC are 150- 200ml/ 666.7m^2 and 100g/666.7m^2 for Jinpentou （liquid application amount： 50kg/666.7m^2. |
