| Abstract: | Control experiment of compound of Beauveria bassiana,Meatarhizium spp.and Sendebao on Dendrolimus punctatus in pinus forests was conducted through orthogonal test design.The experimental results indicated that the optimum combination of three biological pesticide was A3B1C3,namely 400 g/667m2 Beauveria bassiana with spore content is 90 billion/g mixed with Meatarhizium spp.with spore content is 50 billion/g and 1000 g/667m2 Sendebao,the control effect was 94.15%,which showed significant synergistic effects.... |
