This study is conduced to investigate control efficacy of mixture of plant extracts which has been reported to control pest and Bacillus thuringiensis or alone. Control efficacy of 0.025% matrine or mixture of 0.016% matrine and BT () against instar larvae of beet armyworm were best as 98.7% and 93.3%. Treatment of mixture of 0.01% matrine and BT () showed the mortality of 69.3%. In the case of neem, when the mixture of 0.1% neem and BT was applied to larvae of S. exigua, their mortality was 50.0% and weight of larvae were significantly different compare with control and only neem treatment. Therefore For effective control reducing population of beet armyworm and possibility to develop resistance against BT and eco-friendly agents, mixture of 0.016% Matrine and BT () could be used.
