The aim of the research was (i) to evaluate white and cream strains of A. bisporus yields when challenged or not with the pathogen L. fungicola, (ii) to identify the more aggressive pathogen isolates, and (iii) to develop a diagrammatic scale of spot symptoms on infected mushrooms. The experiment was carried out using two strains of A. bisporus (white and cream strains, ABI 19/01 and PB 19/01, respectively) and four isolates of L. fungicola (LF 19/01, FL 19/02, LF 19/03, and LF 19/04). The A. bisporus white strain (ABI 19/01) reached a higher yield of healthy mushrooms compared to the cream strain (PB 19/01) with values of 23.8 and 14.1%, respectively. The LF 19/03 pathogen was most aggressive, reducing the yield of healthy mushrooms by up to 64% for the PB 1/01 strain, and 49.6% for the ABI 19/01 strain. Additionally, for the same isolate, larger mushroom areas were affected, while also displaying symptoms precociously during the second flush. Finally, using the set of visually displayed symptoms assessed in this study, we were able to construct a diagrammatic scale to assist commercial mushroom growers for managing diseased crops.

用于定量双孢蘑菇培养中真菌 Lecanicillium funicola 病害的有用图表量表的设计

该研究的目的是 (i) 评估白色和奶油色双孢霉菌株在受到病原体 L. funcola 攻击或未受到攻击时的产量，(ii) 确定更具攻击性的病原体分离株，以及 (iii) 开发图解受感染蘑菇的斑点症状规模。使用两种双孢杆菌菌株（白色和奶油菌株，分别为 ABI 19/01 和 PB 19/01）和四种真菌 L. 菌株（LF 19/01、FL 19/02、LF 19 /03 和 LF 19/04）。与奶油菌株 (PB 19/01) 相比，双孢蘑菇白色菌株 (ABI 19/01) 的健康蘑菇产量更高，分别为 23.8% 和 14.1%。LF 19/03 病原体最具侵略性，PB 1/01 菌株的健康蘑菇产量减少了 64%，ABI 19/01 菌株减少了 49.6%。此外，对于相同的隔离，较大的蘑菇区域受到影响，同时在第二次冲洗期间也早熟地表现出症状。最后，使用本研究中评估的一组视觉显示症状，我们能够构建一个图表规模，以帮助商业蘑菇种植者管理患病作物。
