Current pesticide recommendations in Ontario specify the weight of material per acre to be applied and leave the volume of diluent to be specified by the sprayer manufacturer (Anonymous 1978). As the volume of liquid applied decreases, the potential for coverage should also decrease for any given concentration of suspension and degree of atomization. Laboratory studies have shown that the percent mortality obtained from residual deposits of pesticide is a function of its stain diameter and distribution as well as total active ingredient per unit area (Fisher et al. 1974)and (Fisher and Menzies 1976, 1978). This study investigates the effect of application rate per hectare and volume median diameter (VMD) on the uniformity of coverage in apple trees.
