Risk index

Presented below is a risk index that takes into account of the various management options/decisions and their relative importances.  This index is provided for the most severe production season either fall or spring depending upon where the production occurs.  Except for South Florida, whiteflies and TYLCV incidences are a major problem in the fall season in the remaining areas of the Southeastern United States.  As mentioned in the other tabs, none of the management options are capable of functioning as stand alone options, but using them effectively could help avert risks.  Econometric analyses with cost-benefit factors indicated that at low risk category there is at least an eighty percent chance for obtaining profits.
