Abstract

Applications each year over a 3-year period of four bi-weekly sprays, containing insecticides fungicides, to apple nursery trees increased tree vigor and tree grade considerably. Sulfur was the most effective fungicide, while demeton-DDT or lindane-DDT provided excellent control. The effects of adequate insect and disease control appeared to be cumulative over the 3-year period. Considerable differences were evident in trees of different apple varieties in response to adequate insect and disease control as indicated in tree growth. Less vigorous apple varieties showed a greater benefit from spraying than the more vigorous varieties, but significant gains from spraying were obtained with all varieties.
