Field evaluation of fungicides for management of Alternaria leaf blight in cotton

Author(s): RJ Chaudhari, GM Parmar, SK Parmar, MM Talpada and AC Detroja
Abstract: Field study was carried out to know the effect of nine different fungicides for minimize intensity of Alternaria macrospora.
The hexaconazole 5% + captan 70% WP (0.1%) was the most effective fungicide with 16.49 percent mean disease intensity. The second effective treatment was hexaconazole 5% EC (0.01%) with 20.01 percent mean disease intensity, propiconazole 25% EC (0.1%) was found effective with 20.96 percent mean disease intensity. Highest seed cotton yield was recorded in treatment of hexaconazole 5% + captan 70% WP at 0.1% (2346 kg/ha), which was at par with carbendazim 12% + mancozeb 63% WP at 0.15% (2211 kg/ha). Minimum yield was recorded in control (1490 kg/ha). Maximum avoidable yield loss of 36.49 percent was recorded in treatment hexaconazole 5% + captan 70% WP at 0.1%. Minimum 15.05 percent avoidable yield loss recorded in treatment chlorothalonil 75% WP at 0.1%.
