↵a TSBpel, TSB amended with pelargonic acid; TSBMg, TSB supplemented with Mg; TSBpelMg, TSB amended with pelargonic acid supplemented with Mg. Data were generated with USDA IPMP 2013 (25, 26). Parameter estimates are

*Y*, maximum population density;_{max}*μ*, maximum growth rate; λ =_{max}*h*_{0}/*μ*, lag-phase duration. Different letters denote statistically significant differences among treatments at a_{max}*P*value of <0.05. The performance of the model was further assessed using the statistical parameters of the root mean square error (RMSE), the residual standard deviation (standard deviation of errors), and the Akaike information criterion (AIC).
