Effect of different fungicides on mango red spot disease pathogen.

[Objective]The objective of the present study was to screen the most-efficient chemical fungicides against mango red spot disease pathogen, and to provide theoretical basis for its control. [Method]The antifungal effects of 12 common fungicides against mango red spot disease pathogen were tested by using the growth rate of strain in vitro. Sterilized water was used as control. [Result]The growth of strain was found to be inhibited by 100.00% when treated with 45% prochloraz EW (450 μg/mL), 25% propiconazol EC (250 μg/mL), 12.5% myclobutanil EC (250 μg/mL) and 25% difenoconazole EC (100 μg/mL). While it was only 89.83, 76.34 and 75.79% inhibited by treating plants with 80% mancozeb WP (1600 μg/mL), 12.5% diniconazole WP (73.5 μg/mL) and 75% chlorothalonil WP (1000 μg/mL), respectively. [Conclusion]The above mentioned fungicides may be used alternatively or in combinations for controlling mango red spot disease pathogen.
