H. M. Kelly, D. L. Wright, N. S. Dufault, and J. J. Marois

May 2015

Research

The objectives of this research were to: (i) develop simple fungicide decision models based on presence of P. pachyrhizi on soybean or kudzu, and leaf wetness duration or rain events; and (ii) evaluate the models and applications based on crop growth stage and non-treated controls by way of disease severity and yield.
