The atmosphere is known to be a good pathway for the worldwide 2007 by Taylor Francis Group LLC. dissemination of pesticides. Pesticides can enter into the atmosphere by spray drift during application postapplication volatilization from soils and leaves and by wind erosion when pesticides are sorbed to soil particles and entrained into the atmosphere on windblown There are few data on the significance of this pathway and on the quantitative effects of soil and environmental factors that influence this This process is most important for herbicides as they are applied either at pre-emergence or postemergence at an early growth stage of the crops . summer cereals maize when .
