Evaluation of simple and complex coffee rust forecasts to time fungicide application :
The net survival ratio values for the monocyclic process (NSRMP) of Hemileia vastatrix were calculated as a product of the parameters: inoculum, yield, and monocyclic process equivalent for environment (MPEE), as determined at three locations during 1982-84. A protective fungicide, copper-oxychloride, was applied when NSRMP major and equal 0.00012 during 1982-83 and NSRMP major and equal 0.00015 during 1983-84. The MPEE values were quantified (complex forecast) or preestablished values were used (simple forecast). During the second cropping season, in addition to copper-oxychloride, triadimefon (systemic) was applied as based on complex forecast. During the first year, based on complex forecast, only two applications of copper-oxychloride was made in one location; whereas, in the other, no application was required. During the second year, in one location, three applications were required as based on complex forecast, and four when based on simple. In the other location, it was necessary to make only one application of copper-oxychloride, based on both simple and complex forecasts. Only one application of triadimefon was required, at each location, based on complex forecast. Local recommendations required four applications of copper-oxychloride per year to be made at fixed times.
