Spray drift from Knapsack sprayers : a study conducted within the framework of the Sino-Dutch Pesticide Environmental Risk Assessment Project PERAP

Drift from the application of crop protection products can cause damage to neighboring crops, ecosystems and human health. In this report, estimations of spray drift with reference to Chinese agricultural systems are provided, based on data from literature and a modeling study. As knapsack sprayers make up the most important tool for pesticide application in China, this study focussed on drift from knapsack sprayers. The results presented in this report will be used to model a pesticide drift and conduct an environmental risk assessment of pesticides in Chinese agricultural systems, as part of the Sino-Dutch Pesticide Environmental Risk Assessment Project PERAP.
