The compatibility of both Gvirens and B.firmus was researched. The fermentation filtrate of Gvirens , under the concentration of 70%, had not distinct inhibitory activity to B.firmus, the biomass of B.firmus would decrease with above the 70% filtrate of Gvirens, but the fermentation filtrate of B.firmus had not inhibitive role to Gvirens. 7, The cooperation control of both Gvirens and B.firm to the pine needle blight was explored:(1) Pathogen inoculation happened prior to the bio-control treatment for 7 days, however, the disease index and control effect had not distinct differences in any treatments even if combination of the two antagonists, but the susceptibility for different kind of pine were different.(2)when antagonist and pathogen were inoculated at the same time, some control effect to the pine needle blight, including certain extent cooperation control of both Gvirens and B.firm were proved, but it wasn't distinct when two antagonists used separately, and the change of the antagonist concentration had little effect to the control effect.

G.virens与B.firmus对松赤枯病的协同控制显示：(1)预先接种病菌后(7天)再进行生物防治处理，不管那种情况，感病指数和防治效果在处理间差异不明显，浓度影响无显著差异，即使是两种生防制剂联合作用也未显著提高其防效，但不同树种间的感病性有明显差异；(2)领抗菌与病原菌同时接种，对松赤枯病有一定防治效果，两菌联合有一定的协同作用，两菌分别单独施用防效差异不显著，浓度变化对防效影响不大；(3)预先接种颇抗菌能显著提高防治效果，两菌联合处理防效更优，感病树种的感病指数可降至13一15，抗病树种的感病指数可控制在3%左右；在同一浓度下B.f1'r功US、叹叮厂即s间无显著差异，在同一领抗菌下，浓度愈高，防效愈高：松，(4)三种生防接种方式的平均效果分析表明，叹F行ens最高平均防效49.5%黑 B。
