通过粉拟青霉菌对板栗剪枝象、板栗二斑栗实象的感病致死力 ,致病机制 ,致病力与土壤含水率关系的研究 ,以及用粉拟青霉菌防治板栗剪枝象和二斑栗实象的大田试验。结果表明 ,粉拟青霉菌是一种高效微生物杀虫剂。其田间防治板栗剪枝象、板栗二斑栗实象的平均感病死亡率分别为 77 3%和 77 8% ,说明该致病菌适合在生产上应用。
Through the Penicillium funiculatus to chestnut pruning elephant chestnut chestnut chestnut real image of the lethality, pathogenic mechanism, the relationship between pathogenicity and soil moisture, as well as the use of powdery mildew fungi chestnut pruning and Field test of two real chestnut. The results showed that Penicillium chrysogenum is a highly effective microbial insecticide. The average mortality rate of chestnut pruning in chestnut and chestnut chestnut in field was 77.3% and 77.8%, respectively, indicating that the pathogen was suitable for production application.
