不同杀菌剂对柑橘煤烟病菌的室内毒力测定
Effectiveness of different fungicides on citrus fuliginous pathogen
摘要
Abstract
of the present study was to screen the highly efficient, low toxic and non-residual fungicides for controlling citrus fuliginous pathogen for alternative use in citrus production. [Method]Toxicity effects of six fungicides on citrus fuliginous pathogen were investigated by measuring the growth rate of fungus. [ Result ]The six fungicides differed in their effects on mycelium growth of citrus fuliginous pathogen. 50% carbendazim WP showed the best antibacte rial activity with 1.8165×10-4 μg/mL EC50 value followed by 70% thiophanate-methyl WP and 80% mancozeb WG with 0.2051 and 1.3470 μg/mL EC50 values, respectively. The effect of 75% chlorothalonil WP was found as worst with 348.2487 μg/mL EC50 value. [Conclusion]The three fungicides, viz., 50% carbendazim WP, 70% thiophanate-methyl WP and 80% mancozeb WG showed better inhibitory effects on citrus fuliginous pathogen, their application may be recommended in plantations affected with citrus fuliginous pathogen.关键词
