Home Orchards: Table 4.7. Pesticide Recommendations for Apples

If the weather is dry, the time between spray applications can be increased to 21 days; if the weather is wet, sprays should be applied every 10 to 14 days. To avoid harming bees, do not use an insecticide in sprays applied during the bloom period. Due to a wide array of various products containing the same active ingredient for insecticide recommendations, when appropriate, the active ingredient is listed instead of the name of formulated product. Follow all instructions and application rates listed on pesticide labels.

CAUTION: Broad-spectrum insecticides (those with a large number of pests listed on the label) have significant potential to be harmful to non-target organisms such as bees and other beneficial or predatory insects.

Notes

a. Match pesticide efficacy against problem pests before selecting spray materials (see Tables 4.5 and 4.6)
b. Where powdery mildew is a problem, add wettable sulfur in prepink through late-June sprays. Do not apply sulfur if the temperature is predicted to be 80°F or higher on the day of application.
c. Safer Soap will probably russet fruit.
d. If cork spot or bitter pit is a problem, the addition of calcium chloride can help reduce their occurence.
e. Summer oil can not be used 14 days before and after captan application or fruit russeting will occur.
