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


Lorsban: Apply at half-inch green. If using with oil, liquid formulations are preferred. Do not make more than one application of chlorpyrifos per year.

petroleum oil- dormant: Oil is indispensible for an integrated mite control program. See also information in Special Programs, Horticultural Mineral Oils, Dormant or Delayed Dormant Use.

captan: Do not use captan on pink through blossom stages. When possible, tank-mix captan with other single-site fungicides to help reduce fungicide resistance development.

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

Flint and Sovran: 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 (mode 11) labeled for use on pome fruits.

Inspire Super: Inspire Super contains an active ingredient similar to the one found in Vangard 75WG. These two products should not be used in rotation.

Luna Sensation: Do not use  before or after Fontelis to minimize fungicide resistance development in FRAC group 7. Luna Sensation contains an active ingredient similar to the one in Flint or Sovran. Do not follow-up Luna with either product.

Rally 40WSP: Place Rally into solution before adding oil. Apply no sooner than half-inch green.

lime sulfur/calcium polysulfide: This material is toxic to pest and predatory mites; destroying apple rust mites, the alternate prey of predatory mites, may predispose the orchard to later spider mite problems.

Topguard: Topguard may cause a mild phytotoxicity on Braeburn apple leaves.
