摘要
甘蔗二点螟以幼虫滞育和休眠两种方式越冬 ,每年发生 1- 4代 ,赤腐病是普遍发生的茎叶病害 ,而凤梨病是低温季节种苗的毁灭性病害 ,马唐和香附子是蔗田的两种恶性杂草 ,同属 C4 植物。采用农业防治为主体 。
Millet borer (Chilo infuscatellus) in sugarcane winters by larva dormancy and stagnancy, occurres from 1 to 4 generations per year. Colletotrichum falcatum is the disease which universally occurres in the stems and leave of sugarcane. Ceratocystis paradoxa is crushing disease of seedcane in low temperature season.
