AI Technical Summary
In the existing technology, the use of biocontrol agents alone has limited control effects on Pseudomonas syringae pv. kiwifruit, Pseudomonas syringae pv. tomato, Erwinia amylovora and Xanthomonas citrus pv. citrus. There is no literature report on the synergistic effect of the combination of Chinese herbal extracts and biocontrol agents, and its antibacterial effect is difficult to predict.
Bacillus polymyxa is compounded with gallnut extract to form an agricultural composition, which is used to prevent and control the above-mentioned diseases. The mass volume ratio of gallnut extract to Bacillus polymyxa is 400:1, which significantly enhances the antibacterial effect on the target pathogens.
The combination of Paenibacillus polymyxa and gallnut extract exhibits good antibacterial effect on the above-mentioned pathogens, which is significantly better than the effect when used alone. It has broad biocontrol potential and is suitable for the prevention and control of various plant diseases.
