The objective of Cornell University's research program is to develop a successful integrated system to control pine and meadow vole damage in the apple orchards of the Hudson Valley. This is being accomplished by determining the effect of habitat manipulation and rodenticides on vole populations. We are also doing research to quantify the amount of damage apple trees sustain from various densities of pine voles. By coupling the results of these two avenues of research, we hope to provide growers with a cost-effective pest management plan. Efficacy of Chlorophacinone (Chempar, Inc.) and Brodificoum (ICI Americas, Inc.) in various populations and treatments were evaluated in 1980 and 1980 (Table I).
