Apple tree disease control has been based on the use of pestcides, a practce that may bring some consequences such as environmental contaminaton, increased producton costs, and risk of developing fungicide resistance. Thus, a strategy to replace the schedule-based applicatons of agrochemicals for preventng diseases is the adopton of warningand forecast systems, which help fruit growers making decisions on fungicide spraying tme. The ratonal use of agrochemicals can reduce producton costs and environmental contaminaton and enable the maintenance of single-site fungicides for a longer period. Therefore, in this review, we will describe the positve and negatve aspects, as well as the perspectves for the use of warning systems in the State of Santa Catarina, addressing its current applicaton on integrated management of apple tree diseases.
