Abstract: Peanut Bud Necrosis Disease (PBND) is a major viral disease affecting the yield levels of groundnut infected by Peanut Bud Necrosis Virus (PBNV) and transmitted by principal vector Thrips palmi. The present study was attempted to assess the pattern of PBN disease incidence using continuous probability distributions for the secondary data collected from ARS, Pavagada, Tumkur for the period of 5 years (2015-2019). Descriptive statistics gave the summary of the data. One-way Analysis of Variance (ANOVA) was adapted to test the significant difference of mean disease incidence percentage among the study years during Kharif season and Duncan’s Multiple Range Test (DMRT) was used to group the yearly mean incidence percentage. Specifically, Weibull, gamma, Exponentiated Exponential (EE), normal and lognormal distributions were examined to evaluate their suitability to represent the measured PBN disease incidence. Akaike’s Information Criterion (AIC) and Bayesian Information Criterion (BIC) measures were used to test the accuracy of the above distributions. Kolmogorov-Smirnov goodness of fit test was used to evaluate the suitability of each of the above distributions.
