Abstract
Some problems about Curvularia leaf spot of maize were studied in Jilin province.The results showed that the diseased leaves stored for 1-3 years in the room and overwintered outside room in one year both had the ability to produce spores;Growth stage of maize has obvious effect on infection capacity to hosts,maize was higher resistant to the pathogen in early stage and lower resistant in late stage of growth;K fertilizer reduced infection rate,but N and P fertilizer had no significant effect on infection of pathogen;Some cultivars and inbred lines such as Jiyu106,CM1,Jidan No.7,Ji846,5002 were resistant to the disease;Effective chemicals had been selected,among the chemicals,thiophanate-methl is the best,ziram-thiram,and procymidone were better than mancozeb,their control effect are 91.59%,88.37%,82.98% and 78.37% respectively.
