Effectiveness of different fungicides on citrus fuliginous pathogen

【Objective】Objective 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 antibacterial 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.
