白术疫病拮抗菌与化学杀菌剂复配及其协同增效作用
Synergistic Effect of Combination of Antagonists and Chemical Fungicides on Atractylodes macrocephala Blight Disease
摘要
Abstract
In order to investigate the synergistic effect of different antagonistic bacteria,Streptomyces and their combination with chemical fungicides on Atractylodes macrocephala blight disease,the compatibility of different antagonists and chemical fungicides was measured by dilution plate and drug-containing plate method at first.Then the plate confrontation method and growth rate method were used to evaluate the inhibition effect of antagonists compound solution and antagonists+chemical fungicides compound on Phytophthora sansomeana AMPH-1,which was the pathogen of A.macrocephala blight disease.The results showed that the Bacillus BZX-2,BZX-11 and X-119 strains had good compatibility with dimethomorph.The combination of BZX-2+BZX-11+X-119 had the best inhibition effect,and the inhibition rate reached 75.45%,which was lower than that of the treatment using X-119 alone.When the ratio of antagonist combination of Bacillus strains and dimethomorph was 1∶2,the inhibition effect reached 68.61%,which increased 16.83%and 13.59%compared with dimethomorph treatment and antagonists treatment,respectively.By the pot experiment in greenhouse,it was found that the greenhouse control efficiency of BZX-2+BZX-11+X-119 combination with equal proportion mixing was 72.72%on A.macrocephala blight disease,which was 45.45 percentage points higher than that of BZX-2 treatment.Above results provided effective basis for the new strategy of A.macrocephala blight disease control.关键词
