Cold-fogging crop protection products in greenhouses is an easy to handle and time and labour saving method. However measurements of depositions on commercial tomato and eggplant crops in two greenhouses in Switzerland revealed that active ingredients distribution in the greenhouses was very uneven. Furthermore there were spots where unacceptably high residues were found on harvested fruit. Cold-fogging application method must and can be improved through technical measures. The choice and the dosage of the products should rely on solid data sets made available to the extension service.
