Recently, there have been several attempts to introduce new pesticide dosing methods for fruit orchards and vineyards. However, in Southern Europe, these new methods have not been adopted. This is mainly because farmers lack confidence in the new methods. This lack of confidence partly results from the failure of the new dosing methods to take into account tree leaf density. For this reason, the most common dosing method is the traditional one which is used to control the concentration of the pesticide solution to be sprayed. In this context, farmers tend to spray a greater volume than is necessary and therefore frequently overdose their orchards. A method for estimating the Leaf Area Index was developed. This methodology was then implemented in a decision support system and validated over four seasons, 2009-2012. The decision support system allowed significant reduction in the volume of pesticide sprayed while maintaining the same level of biological efficacy. This system could provide the basis of a universal dose method for pesticide spraying in tree crops.
