Management of powdery mildew in cumin through chemicals

India is the leading country in the world for cultivation, production and consumption of seed spices in general and cumin (Cuminum cyminum L.) in particular. The diseases such as blight, powdery mildew and wilt are the major constraints of low productivity of cumin. Among them, powdery mildew (Erysiphe polygoni L.) is very destructive disease of cumin and may cause loss in yield and quality deterioration, if proper and timely measures are not taken. At Seed Spices Research Station, Sardarkrushinagar Dantiwada Agricultural University, Jagudan (Gujarat), extensive research works for each of the chemicals have been carried out on powdery mildew management in cumin during last decade. The foliar application of metiram 55% + pyraclostrobin 5% WG @ 900 a.i.g ha (1500 g ha ) was found effective for the management of -1 -1 powdery mildew disease and increasing seed yield of cumin (2011). Two sprays of tebuconazole 25 WG @ 750 g ha proved its superiority against powdery mildew disease of cumin and it's also reported that -1 tebuconazole 25 WG is non-phytotoxic to cumin crop (2016). Two foliar sprays of difenoconazole @ 250 ml ha were found effective against powdery mildew of cumin (201 ). A combination of fungicides, -1 6 tebuconazole 50% + trifloxystrobin 25% WG @ 350 g ha proved its superiority against powdery mildew -1 disease of cumin with increase in the yield (2018). On the basis of the two years of investigation it has been concluded that captan 70% + hexaconazole 5%WP @ 750 g ha was found effective against powdery -1 mildew of cumin. Higher dose of captan 70% + hexaconazole 5% WP@ 3000 g ha did not produce any -1 phytotoxic symptoms on cumin crop at different crop stages during sprays as captan 70% + hexaconazole 5% WP is non-phytotoxic to cumin crop (2018). The hexaconazole 5 EC @ 1000 ml ha was found -1 effective against powdery mildew disease in cumin (2021). Foliar application of kresoxim methyl 50 SC @ 375 ml ha were found effective against and powdery mildew disease of cumin with higher seed yield -1 (2023)..
