Effectiveness of hedges and nets in reducing the risk of drift and exposure of local residents during vineyard spraying: initial results

Abstract

IFV and INRAE have used the EoleDrift test rig to measure the drift reduction performance of two types of plot modification (shrub hedges and windbreak nets). Whatever the sprayer used and the type of drift measured (airborne, sedimentary, exposure of mannequins), the reduction rates measured in the presence of physical barriers are relatively stable and high. By combining such barriers with efficient spraying equipment, reduction rates of over 95 % can be achieved.
