India: Macmillanc2006  ap. 325-334.  aAFITA/WCCA 2006.  aThis paper discusses about problem-solving treatment tasks in a general framework that supports the tasks of diagnosis, investigation and treatments of disorders in plantations. In this paper we focus on the use of a framework that incorporates concepts of abductive inference, fuzzy set logic and decision theory for the tasks of treatment, with an illustration in corn plantations. Here, the knowledege is modeled as graphs in which the arcs are from treatments to diagnoses and inference is also abductive. This framework also models time durations and intensity of manifestations as fuzzy sets, and, in the partucular case of agriculture, it takes into account the favorable conditions for the development of a given disorder and the severity of its manifestations to recommend a treatment, together with other important factors such as risk and cost.  aAgriculture  acontrol methods  aFuzzy logic  aPlant diseases and disorders  aplant pathology  aAgricultura  aAbductive inference  aDesordens  aDoença da planta  aInferência abdutiva  aMétodos de controle1 aSANDRI, S.1 aWAINER, J.1 aMORANDI, M.
