EFSA studies S Europe protected crops
There are potential agrochemical emissions to surface water from crops in greenhouses, and these emissions are significantly affected by the climatic conditions of the growing system, concludes a study by the European Food Safety Authority (EFSA). A more controlled climate in the greenhouse can reduce emissions, and temperature has a greater influence than the amount of excess irrigation water, it says. The study focused on greenhouses in the Mediterranean region. It is part of an EFSA project initiated in 2008 that aims to develop specific guidance on risk assessments for pesticides used on protected crops ( Agrow No 590, p 9). Current methods to estimate pesticide emissions only relate to open fields.
