Abstract
Anthracnose and powdery mildew are the two common maladies that attack mango at flowering and inflict heavy loss to fruit
production. Seven organic and one inorganic fungicide were evaluated for their effectiveness against these diseases. In all,
three bloom sprays were made, first at 25% flowering and two later sprays at 15-day intervals. Best results were achieved with
Nativo 75% WDG (Tebuconazol+ Trifloxystrobin) which controlled anthracnose by 92.03% and powdery mildew by 90.19%.
It was followed by Cabriotop 60% WDG (Metiram + Pyraclostrobin) which reduced incidence of these diseases by 89.08%
and 88.04%, respectively, whereas Topsin-M 72% WP (Thiophanate methyl), Score 25% EC (Difenoconazol) and Shincar
50% SC (Carbendazim) provided less than 80% control. Topas 100% EC (Penconazole) and Vangard 25% EC (Tridamenol)
were effective against powdery mildew (89.96% and 91.87%) and Champion 77% WP (Copper hydroxide) was against
anthracnose only (82.64% disease control). In general, all the fungicide treatments significantly reduced incidence of the
diseases and produced higher yield of quality fruits than control in both years.
