测试了不同的碳源和氮源以及辅助物质，以确定它们对桃枝枯病病原体、Monilinia laxa 及其三种拮抗剂（青霉、紫青霉和黑附生菌）生长和孢子形成的影响，因为通过真菌拮抗剂处理进行枝枯病生物防治的成功取决于添加到桃枝枯病病原体中的营养物类型。 拮抗剂制剂。从这些实验室实验中选择了蔗糖-酒石酸铵、葡萄糖-(NH4)3PO4-叶酸和乳糖-KNO3的组合，因为它们分别增强了常绿假单胞菌、紫红假单胞菌和龙葵的生长和孢子形成，但不增强松毛假单胞菌的生长和孢子形成。在温室实验中，施用拮抗剂与相应增强营养素的混合物后，枝枯病减少了。
Different carbon and nitrogen sources and accessory substances were tested to determine their effect on the growth and sporulation of the peach twig blight pathogen, Monilinia laxa, and of three of its antagonists (Penicillium frequentans, Penicillium purpurogenum and Epicoccum nigrum), since the success in twig blight biological control by treatments with the fungal antagonists depends on the type of nutrients added to the antagonist formulation. Combinations of sucrose-ammonium tartrate, glucose-(NH4)3PO4-folic acid and lactose-KNO3 were selected from these laboratory experiments because they enhanced the growth and sporulation of P. frequentans, P. purpurogenum and E. nigrum, respectively, but not M. laxa. In glasshouse experiments, twig blight was reduced following the application of mixtures of antagonists with the corresponding enhancing nutrients.
