Botrytis blight caused by Botrytis gladiolorum is the most devastating disease under North Indian conditions. The development and spread of this disease is favoured by cool and moist weather conditions generally prevailing in the months of February and March under Punjab conditions. The spatial and temporal dynamics of any disease provide valuable information on development of disease epidemics. The current experiments were planned to measure spatial and temporal development of Botrytis blight in susceptible (Sancerre) and resistant varieties (Nova Lux and Jacksonville Gold) of gladiolus under natural field conditions. It was observed that there was an increase in spread of the disease with time in both the susceptible and resistant varieties. The spread of disease in the varieties Sancerre, Jacksonville Gold and Nova Lux, varied from -500 to 425, -37.. View More»
