T.
A. Zitter FEB 2009
A. Powdery Mildew (occurs every
year)
Beginning when lesions are
1st detected, and the PM sprays should include:
All
strobilurin (Group 11) fungicides have been removed due to fungicide
resistance. 11Amistar, Quadris, Ouadris Opti, Sovran,11
+ 7Pristine
• 13Quintec (only currently registered on muskmelon, spec. melons and watermelon);
begin usage early in the PM cycle and see below).
Use
the following in an alternating program:
· M2Sulfur (good protectant, alone or tank-mixed
with Quintec or those below)
• 3Rally Hi rate 5 oz + M5Bravo (or OLP)
or
• 3Procure Hi rate 8 oz + M5Bravo (or OLP)
• or alternated with other protectants like JMS Stylet mineral oil, coppers, etc.)
B. Most seasons when
moisture is adequate after fruit set (end July, beginning Aug), and if rotation
of less than 2 years is practiced then --
Gummy
Stem Blight/Black rot sprays should include:
• M5Bravo (or OLP) 11Amistar, Quadris, Ouadris Opti, Sovran,11 + 7Pristine,
• 1Topsin M (OLP) + M5Bravo (or OLP)
C. If Plectosporium has previously
been found in Zucchini Squash or Pumpkins, and less than 2 year rotation is
practiced, and if July-August rains occur (wet soils) then Plectosporium sprays (for these crops
only) should include:
• M5Bravo (OLP) or M3 maneb or
• M3mancozeb (not Pumpkin or Winter Squash) Alt. with 11Cabrio, Flint, or Amistar)
D. If Phytophthora has previously
occurred on your farm (utilize disease management practices) or
forecasts exist for Downy Mildew airborne
from Michigan, Ontario, Pennsylvania or New Jersey --then
DM
(DM)/Phytophthora (P) sprays should include:
• #=Six top DM choices,
used preventatively: #28Previcur Flex (DM) + protect)
• #21Ranman (DM, P)
• #11+27Tanos (DM, P
suppression + protect)
• #27Curzate (DM) + protectant
• #22+M3Gavel (not Pump or W. Squ)(DM, P)
• #43 Presidio (fluopicolide) Not Registered
• Alternate with40Acrobat (Forum)(DM,P) or
• 11Reason (DM) or
• 33Phosphoric acids Agri-Fos, Fosphite, Fungi-Phite, ProPhyt, Kphite, Phostrol, Rampart, Topaz (DM, Phytophthora, Pythium) or
• 4+M5 Ridomil Gold Bravo (Resistance issue of mefenoxam for *DM*); coppers; Revus (suppression for
both)
E If SCAB SHOULD BE AN ISSUE:
· M5Bravo or OLP
· M1 fixed coppers some
are labeled
