| Popis: | In order to reduce the use of insecticide, the application of Beauveria bassiana may be an alternative control. The objective of this study was to evaluate the efficacy of B. bassiana for controlling mungbean pest. The experiment was conducted in Ngale Research Station from February to May 2017, using randomized block design, seven treatments, four replicates. The treatments were frequency of application; P1= six times, P2= five times, P3= four times, P4= three times, P5= once, P6= full protection using chemical insecticide, and P7= no protection. Application of B. bassiana four to six times can suppress the population of Empoasca sp., Riptortus linearis, and Maruca testulalis, but did not significantly different with the application of chemical insecticide. Based on the seed weight, application of B. bassiana six times (659.7 g/plot) led to significantly high as compare with the application of chemical insecticide (374 g/plot). Application of B. bassiana tended to be secure to natural enemies, especially Coccinella sp., Oxyopes javanus, and Paederus fuscipes. Both of those predators were not found on the application of chemical insecticide. Hence, B. bassiana can be recommended as a biological agent in integrated pest management component on mungbean because of effective and environmentally friendly. |
