Spraydrift is the loss of Plant Protection Products due to climatic effects and/or a poor application practices Spraydrift is a complex process that depends on the application conditions, spray, type of crop, atmospheric conditions andphysicochemical properties of the agrochemical Due to the large number of factors that affect spray drift, anexperimental evaluation of the risk of drift for all operating conditions, spray equipment and climatic factorscorresponding to a given application is very difficult to carry out In this context, mathematical models are a key tool tothe phenomena that lead to spray drift and find appropriate application conditions that lead to minimize thecontamination risksInthis work, a mathematical model to predict the spray drift produced by an agricultural spray nozzle is presented Themodel is based on continuous distribution functions The model is implemented on gPROMS software
