1 CAUTION: Do not use Captan or combinations involving Captan, with oil or within 4 days of an oil application. Check for tank-mix compatibility of dodine with oil. Some sporadic resistance of scab to dodine has occurred where used heavily for several years.
2 See Rally label for rate per acre
adjustment based on tree height. When used in an
after-infection strategy a follow-up application should be made a
week later to kill the fungus in the lesion. Do not combine
Merivon with emulsifiable concentrate solvent-based formulation
products. Do not combine Merivon with crop oil
concentrate or methylated seed oil adjuvants.
3 CAUTION: The EBDC fungicides (mancozeb and Polyram) are registered for limited usage on apples for control of scab, rusts and some summer diseases. The grower is given the option of using one of two schedules:
A. Apply 6.0 lb of the 75DF or 80DF formulations per acre per application from green tip stage through bloom, maximum 24 lb per acre per year.
B. Apply 3.0 lb per acre from green tip stage through second cover or up to 77 days to harvest, maximum 21 lb per acre per year.
The above schedules are not to be combined, so you must decide before the first spray which schedule best fits your needs. Because EBDCs have been most beneficial for summer disease control (especially bitter rot) and in applications which require a broad spectrum fungicide which is compatible with oil, the second option (3 lb per acre up to 77 days to harvest) is listed here as the preferred usage pattern. When used in the early cover sprays (or up to 77 days to harvest) EBDCs may have benefits for residual early summer disease control and compatibility in programs where oil is used with Sevin as a thinner. The 3.0 lb per acre EBDC rate cannot be relied on by itself for early season or summer disease control.Combinations with sterol-inhibiting fungicides (Indar, Inspire Super, Rally, Procure and Topguard) have been well tested and are recommended for early season disease control (apple scab, rusts, powdery mildew); the benzimidazoles (Benlate and Topsin-M) are compatible with EBDCs and provide supplemental control for Brooks spot, sooty blotch, fly speck, black rot and white rot, but not for bitter rot. Captan and ziram are protectant fungicides that provide supplemental summer disease control. Incompatibilities among combinations of captan, ziram, mancozeb or Polyram are not anticipated but are not well tested. Captan is incompatible with oil. See the additional note about EBDCs under the second cover spray.
4 CAUTION: Sovran, Flint, Luna Sensation,and Merivon are strobilurin fungicides that will require a selected use strategy because of concern about development of resistance. These fungicides have benefits for early season and summer disease management; however, they should not be used in more than two consecutive sprays. They should be tank mixed with a protectant fungicide and alternated with two or three applications of non-strobilurin fungicides from other chemical classes for control of all diseases concerned. These fungicides may not provide curative activity under heavy rust pressure. Areas with heavy rust pressure will need to rely on sterol-inhibiting fungicides during periods of peak rust activity.
5 Do not combine Merivon with
emulsifiable concentrate solvent-based formulation products.
Do not combine Merivon with crop oil concentrate or
methylated seed oil adjuvants.

1 See notes (silver tip - green tip spray).
2 RAA is the most important aphid to control at this time. SA can be controlled effectively later in the season (by natural enemies and/or sprays). But action taken now for RAA will also control SA.
3 Where ERM eggs are abundant and Stethorus punctum is present, Stethorus adults will begin to move into trees.
4 RBLR eggs are only killed if in direct contact with Lannate spray.
5 Defoliating caterpillars include tent caterpillars, cankerworms, and cutworms.
6 Pyrethroids should be applied at most once per season, preferably at 1/2 green but no later than tight cluster-prepink.
7 May be applied once per season, until 45 days before harvest; petal fall application is preferred.
May be applied once per season, until 28 days before harvest; petal
fall application is preferred. Do not apply in less than
