Abstract :In this study, the effects of time and doses of potassium bicarbonate (KHCO3) on mycelial growth and sclerotial germination of Botrytis cinerea was evaluated by mathematical modeling with multi regression analysis. All equations produced for mycelial growth and sclerotial germination of B. cinerea were derived as affected by doses and times. ANOVA and multi-regression analysis showed a close relationship between actual and predicted mycelial growth and sclerotial germination of B. cinerea. The models developed to predict mycelial growth and sclerotial germination were, respectively, MG=(a)–(b x T2) + [c x (D x T)] and SG=(a)+(b x T)–[c x (D x T)]+[d x (D² x T)], where a, b, c and d represent co-efficients obtained through multi regression analysis, T represents time and D represents dosage. R2 values of mycelial growth and sclerotial germination were 0.83 and 0.81, respectively. Standard errors were found to be significant at p<0.001.
