Aphids: this recommendation will be effective on apple aphid, apple grain aphid, and rosy apple aphid, but less so on woolly apple aphid

Cutworms: Apply thoroughly to lower trunk and base of tree.

Leafrollers (Pandemis): While too early for obliqebanded leafrollers, this timing is appropriate for Pandemis


Bacillus thuringiensis subsp. kurstaki: Bts are stomach poisons so complete coverage is very important for control. Two or three applications are usually required. Apply when forecasts predict a warm weather pattern, above 65 degrees, for 3 or more days.

Apple mildew: DO NOT APPLY lime sulfur or calcium polysulfide WHEN TEMPERATURES EXCEED 75F. Other fungicides may be used at higher temperatures. Treat mildew-susceptible varieties only.

Dithane M45 80W: Do not apply after bloom. See label for restrictions.

Flint and Sovran: Flint and Sovran are from the same chemical group. To limit the potential for development of fungicide resistance, do not make more than four applications of strobilurin fungicides per season. Do not make more than two sequential applications of strobilurin fungicides. This limitation is inclusive to all strobilurin fungicides labeled for use on pome fruits.

Fontelis: Fontelis and Luna Sensation are from the same chemical group (7). Apply one of them ONLY at the same growth stage.

Inspire Super: Inspire Super and Vangard are from same chenical group. Use one of them ONLY.
