 en Environmental impact of an orchard winter wash and early season pesticide applications on both a beneficial and a pest mite species in Bramley apple orchards
A. G. S. Cuthbertson and A. K. Murchie

Abstract

Apple orchards often receive winter-washes to help aid invertebrate pest control. These can have detrimental environmental consequences. The application of winter-wash increased Aculus schlechtendali check for this species in other resources numbers while a decrease in numbers of the beneficial mite Anystis baccarum check for this species in other resources was observed. The application of early season pesticide treatments produced mixed results in relation to A. schlechtendali. Pirimiphos-methyl had no apparent detrimental effect on A. baccarum, whereas pirimicarb and phosalone reduced A. baccarum populations. The potential to incorporate an orchard winter-wash and early-season pesticide applications within integrated pest management strategies is discussed.
