Abstract: Efficacy tests of insecticides for controlling the RBB were determined in both of laboratory and paddy field in 2008. Results showed that the application rate of 40 milliliters per 20 liters of water of ethiprole (Curbix 10 percent SC) and 6 grams per 20 liters of water of clothianidin (Dantosu 16 percent WG) were most effective under lower than economic threshold of RBB densities condition. Means of insect densities obtained from those two spray treatments were not significantly different from the recommended
carbosulfan (Posse 20 percent EC) at the rate of 80 milliliters per 20 liters of water with percentage of the efficacy of 53.5 and 51.5 percent and were higher than those of recommended one (44.7 percent). In the other hand, efficacy of dinotefuran (Starkle 10 percent WP) with application rate of 10 grams per 20 liters of water and thiamithoxam (Actara 25 percent WG) at the rate of 2 grams per 20 liters of water were 36.0 and 25.3 percent respectively and indicated of less effective than the recommended insecticide.
