White button mushrooms yield instability in artificial cultivation, often caused by crop diseases. The main disease is wet bubble disease. The appearance of its causative agent, , may lead to total yield loss. The microbiocontrol of is focused on casing soil antagonist use. Since no industrial producer strains of polyfunctional biologics have been used in previous studies, our research goal was to characterize the effect of B-10 and M-22 on a mycopathogen and reveal its control possibilities. The reason for B-10 and M-22 use in mycopathogen control has been revealed by interactions between producer strains and the studying of . The suppression of development by producer strains was established, indicating a prolonged B-10 and M-22 effect on the mycopathogen. High biological efficacy in both strains at the early stages of mycopathogen development upon introducing them into the wells and spraying was shown: B-10-50.9-99.6% and M-22-57.5-99.2%, respectively ( ≤ 0.05). Significant differences between producer strains were not revealed, although during the first day of exposure to developed colonies, M-22 showed greater activity. The high efficiency of preventive treatment when producer strains completely suppressed mycoparasite development permits us to recommend them both for introducing when preparing casing for control.
白蘑菇人工栽培产量不稳定，常由作物病害引起。主要病害是湿泡病。其病原体的出现可能导致总产量损失。对其微生物防治主要集中在使用覆土拮抗剂。由于以往研究未使用过多功能生物制剂的工业生产菌株，我们的研究目标是表征B - 10和M - 22对一种真菌病原体的影响，并揭示其防治可能性。通过生产菌株之间的相互作用以及对……的研究，揭示了使用B - 10和M - 22防治真菌病原体的原因。确定了生产菌株对……生长的抑制作用，表明B - 10和M - 22对真菌病原体有持久作用。将它们引入孔中并喷雾后，在真菌病原体发育早期，两种菌株均显示出高生物活性：B - 10为50.9 - 99.6%，M - 22为57.5 - 99.2%，分别（P≤0.05）。虽然在接触已发育的……菌落的第一天，M - 22显示出更大活性，但未发现生产菌株之间有显著差异。当生产菌株完全抑制了真菌寄生物的生长时，预防性处理的高效率使我们推荐在为……防治准备覆土时引入这两种菌株。
