Abstract
Blights, blasts and leaf spot diseases of rice limit the grain yield and deteriorate the produce quality. A field study was carried out for evaluating various fungicides to manage paddy diseases; brown leaf spot, blast & sheath blight under field conditions at research area of Adaptive Research Farm Sheikhupura, Punjab Pakistan during crop season kharif 2018 & 2019. An experiment was conducted in RCB design with three repeats and five treatments including control. Treatments comprised of four different fungicides viz: Azoxystrobin + Difenoconazol, Kasugamysin + Copperoxychloride, Copper Hydroxide & Trifloxystrobin + Tubeconazol @ 500 ml, 625 ml, 625 g & 160 g ha-1 respectively and a control (untreated check plot). Among the chemical fungicides Azoxystrobin + Difenoconazol @ 500 ml ha-1 was found effective against brown leaf spot and sheath blight with 84.6 % & 81.7 % decrease over control along with 37.4 & 36.7 percent higher yield than check plot followed by Trifloxystrobin + Tubeconazol with 74.8 & 74.3 percent protection values as compared to control during years 2018 & 2019 respectively. In case of paddy blast the fungicide containing Kasugamycin + Copperoxychloride showed better results with 82.5% & 79.4% decrease over control. Maximum incidence level of Brown leaf spot, paddy blast and sheath blight were found in control (non-treated plot) during both years. So, azoxystrobin+ difenoconazol and kasugamycin containing fungicides could be suggested for management of brown leaf spot, sheath blight and paddy blast.
