Abstract: Based on the field experiments of 2013-2014, the ‘Red Chief’ apple was used for studying the control efficiency of fourteen fungicides against apple alternaria leaf spot. The results showed that the effect of 10% difenoconazole WG, 430 g/L tebuconazole SC and 70% propineb WP against apple alternaria leaf spot were the best. In 2013 and 2014, the control effects of the three treatments were 81.65%, 81.24%, 79.97% and 82.36%, 86.14%, 83.42% respectively in spring-growth and were 76.22%, 77.83%, 73.84% and 81.80%, 82.18%, 75.58% respectively in autumn-growth. The control efficiency of 50% captan WP, 50% cyprodinil WP and 10% polyoxin WP against apple alternaria leaf spot were also satisfying. In 2013 and 2014, the control effects of the three treatments were 78.35%, 78.17%, 77.34% and 81.89%, 82.03%, 81.88% respectively in spring-growth and were 73.47%, 72.58%, 74.45% and 78.73%, 74.69%, 77.44% respectively in autumn-growth. But the effect of 80% mancozeb WP against apple alternaria leaf spot was poor and lower than other fungicides. By analysis of variance, significant difference was found between triazole fungicide 10% difenoconazole WG and protective fungicide 80% mancozeb WP in two years.
