一株生防拟盘多毛孢菌B3及其应用
By screening and identifying Polychaete spp. B3, spore suspensions or fermentation broths were prepared, solving the problem of poor control of broadleaf weeds by biocontrol bacteria. This achieved effective control of broadleaf weeds and demonstrated good environmental friendliness and control efficacy.

AI Technical Summary
Existing technologies for controlling broadleaf weeds using biocontrol bacteria are not very effective, and the types of bacteria are limited, making it difficult to effectively solve the environmental problems and threats of resistant weeds caused by chemical herbicides.
A strain of *Pterocarya spp.* B3 is provided for the preparation of microbial agents, especially spore suspensions or fermentation broths, to inhibit the growth of broadleaf weeds such as lambsquarters, cleavers, and mallow.
Polychaete B3 exhibits significant pathogenicity against broadleaf weeds. Spraying with the fermentation liquid can significantly inhibit weed growth, with an incidence rate as high as 62.85%~97.78%. This enriches the microbial control resource pool and provides an environmentally friendly weed control solution.
