Epidemiological Study of Chilli Anthracnose

The present research investigation, Epidemiological Study of Chilli Anthracnose, the experiment was conducted in Randomized Block Design (RBD) to know the influence of weather parameters on disease development in the field located at Namakkal district of Tamil Nadu. For the prediction of disease occurrence, the percent disease index (PDI) was correlated with six meteorological parameters statistically. The Correlation matrix showed that the disease severity was positively and significantly correlated with Wind Speed (0.814). Factors like RH max (-0.871) and RH min (– 0.850) were negatively and significantly correlated. T min (–0.48) and DP (–0.381) were also negatively correlated, though they were not significant. T max (0.257) was found to be positively correlated but non-significant.
