This study, we isolated and evaluated the antagonistic bacteria from healthy corn plant, 10 bacterial antagonists from 310 strains were mixed synthetic medium for preliminary test with corn borer. The Cut young corn pod that dipped with antagonistic bacteria suspension in CRD design were investigated under plastic box conditions, compared to plants treated with synthetic insecticide (cypermetrin). Fifty corn borer per plant arranged in CRD design were investigated under control conditions. The treatment with strain BCA2 BCA4 BCA7 BCA8 and BCA10 provided the highest mortality of corn borer with 100 percent reduction after 6 hr and BCA4 BCA8 and BCA10 showed the highest mortality of corn aphid with 100 percent reduction at 48hr after treated. Moreover, the... |
