摘要
调查发现云南澳洲坚果树一种新的果实病害,暂定为澳洲坚果黑果病;经形态学和分子生物学鉴定,病原菌为假毛丛赤壳菌(Nectria pseudotrichia);药剂毒力测试表明,50%多菌灵、450 g/L咪鲜胺、250 g/L丙环唑乳油等3种农药在25℃时抑制菌丝生长的效果达到极显著,推荐用于田间防治试验。
A new fruit disease has been found in Yunnan macadamia orchard based on survey, it is called tentatively as macadamia black fruit disease. The pathogen was identified asNectria pseudotrichia of scab through morphological and molecular biological analysis. The virulence test showed that three pesticides of 50% carbendazim, prochloraz (450 g/L),propiconazole emulsifiable (250 g/L) at 25 ℃ have extreme inhibiting effect on mycelial growth. It is recommended to put into use in field.
