核盘菌的存活在很大程度上取决于菌核的产量和生活力。减少菌核的产生对于控制病原体是至关重要的。对一株哈茨木霉和两株解淀粉芽孢杆菌进行了体内外生物防治试验。菌核研究表明，T. harzianum和B.解淀粉菌抑制菌丝和菌核的生长和产生。当地分离物、T. harzianum和B.在体外研究中，解淀粉杆菌似乎分别表现出真菌寄生和寄生。作为拮抗菌，这些菌株对番茄、南瓜和茄子幼苗的保护率均在80%以上。菌核T. harzianum和B.与两种商品化产品PlantShield和SoilGard相比，根据作物植物，核盘菌的生长速率相似或略低。(C)2008爱思唯尔有限公司保留所有权利。
The survival of Sclerotinia sclerotiorum, to a large extent depends on the production and viabilty of sclerotia. Reduction in the production of sclerotia is essential in the control of the pathogen. A local Trichoderma harzianum isolate and two Bacillus amyloliquefaciens isolates were evaluated in vitro and in vivo as potential biological control agents (BCAs) against S. sclerotiorum. The study showed that T. harzianum and B. amyloliquefaciens inhibited the growth and production of mycelia and sclerotia. The local isolates, T. harzianum and B. amyloliquefaciens appeared to exhibit mycoparasitism and antibiosis, respectively, in the in vitro study. As antagonists, these isolates protected over 80% of tomato, squash and eggplant seedlings inoculated with S. sclerotiorum. The efficacy of T. harzianum and B. amyloliquefaciens compared with two commercial products, PlantShield and SoilGard in the control of S. sclerotiorum was similar or slightly lower depending on the crop plant.
