Dose expression for “3D” crops represents one of the most controversial aspects linked with a proper and optimised use of pesticides. Researchers, regulatory bodies and private companies have been working in the last years in order to find a reasonable, logical, objective and harmonized method to express the amount of pesticide to be applied in crops as vineyard and orchards. This workshop is addressed to go a step forward in this challenge topic, combining experiences from different stakeholders and providing possible improvements to the subject.
