Fruiting Vegetables - Diseases
formulations of copper (Badge, Champ, Kocide) are labelled
for use. See label for directions. Copper-resistant strains of
the bacterial spot pathogen are common in the Midwest.
Mancozeb products (e.g., Dithane, Manzate, Penncozeb)
when tank-mixed with copper products, allow more copper to
become available on the leaf surface and so may help manage
copper-resistant bacterial strains. REI: 4 to 48-hour. PHI: 0day.
FRAC M01. OMRI-listed.
LifeGard WG (Bacillus mycoides isolate J) Eggplant,
Pepper, Tomato | 1-4.5 oz. per acre. 1-4.5 oz. per acre or 4.5
oz. per 100 gals. water. Suppression only; can be used in a
rotational program with effective fungicides to reduce
synthetic fungicide use REI: 4-hour. PHI: 0-day. FRAC 44.
OMRI-listed.
Regalia (5) (Reynoutria sachalinensis extract) Eggplant,
Pepper, Tomato | 1-4 qts. per acre. Use in a program with
copper products. For damping-off, | For Fusarium, Pythium,
Rhizoctonia spp., use 1-4 qts. per acre. On greenhouseproduced
seedlings, drench planting medium with 1-2 qts. per
gal. water or dip seedlings in solution of 1-2 qts. per 100 gal.
water immediately before transplanting. REI: 4-hour. PHI: 0day.
FRAC P05. OMRI-listed.
Serenade Opti (26.2WP) (Bacillus subtilis strain QST713)
Eggplant, Pepper, Tomato | Use Serenade Opti at 14-20
fl. oz. per acre, or Serenade ASO at 2-4 qts. per acre. Can be
used in a rotational program with effective fungicides to
reduce synthetic fungicide use. REI: 4-hour. PHI: 0-day.
FRAC 44. OMRI-listed.
streptomycin products (Streptomycin sulfate) Pepper,
Tomato | Use 17% products at 16 oz. per 100 gals of water, or
50% products at 5.3 oz. per 100 gals. of water to maintain a
concentration of 200 ppm. Apply one or two times to
seedlings, alternated with a fixed copper product compound
beginning at the two-leaf stage. Not labeled for use after
transplanting (greenhouse only). REI: 12-hour. FRAC 25.
Tanos (DF) (famoxadone, cymoxanil) Pepper, Tomato |
Tomato: Early blight at 6-8 oz. per acre. Late blight and
anthracnose at 8 oz per acre. For suppression of bacterial
diseases of tomato, 8 oz. For late blight, tank-mix with a
contact fungicide with a different mode of action. Pepper:
Anthracnose at 8-10 fl. oz. REI: 12-hour. FRAC 11, FRAC
27.
Buckeye Rot of Tomatoes - Phytophthora
Oomycete
These diseases are favored by heavy rains and waterlogged
soils. Symptoms include discolored fruit and declining plants.
Consider fungicide drench. Regular fungicide schedule may
lessen impact of buckeye rot.
Non-Pesticide
Tomato | Rotate to non-Cucurbit, non-Legume, and nonSolanaceous
crops for 3 years. Use raised beds, staking, and
mulch to improve drainage, air flow, and reduce splashing.
Prompt destruction of the finished crop with tillage to rapidly
breakdown tissue is an important method to prevent disease
build-up. Anaerobic soil disinfestation (ASD) is an effective
sterilization method for greenhouse and high tunnel soils that
contain this pathogen.
Pesticide
azoxystrobin products (azoxystrobin) Tomato | Use 2 lb.
a.i. per gallon formulations (Acadia, AFrame, Arius, A-Zox,
AzoxyStar, Azoxyzone, Dexter, Quadris, Satori, Tetraban,
Willowood Azoxy) at 6.0-15.5 fl. oz. per acre. Use 3.3 lb. per
gallon formulations (AZteroid FC 3.3) at 3.9-9.7 fl. oz. per
acre. REI: 4-hour. PHI: 0-day. FRAC 11.
copper products (copper hydroxide, copper octanoate,
copper oxychloride, copper sulfate, copper diammonium
diacetate complex, cuprous oxide) Tomato | Several
formulations of copper (Badge, Champ, Kocide) are labelled
for use and may improve efficacy of fungicides against
Phytophthora blight when tank mixed at labeled rates. See
label for directions. REI: 4 to 48-hour. PHI: 0-day. FRAC
M01. OMRI-listed.
Gavel 75DF (zoxamide, mancozeb) Tomato | 1.5-2 lbs. per
acre. REI: 48-hour. PHI: 5-day. FRAC 22, FRAC M03.
Orondis Opti Premix (SC) (oxathiapiprolin,
chlorothalonil) Tomato | 1.75-2.5 pt. per acre. REI: 12-hour.
PHI: 3-day. FRAC 49, FRAC M05.
Orondis Ultra Premix (SC) (oxathiapiprolin,
mandipropamid) Tomato | 5.5-8.0 fl. oz. per acre. Alternate
with fungicides that have a different mode of action. Use
either soil applications or foilar applications of
oxathiapiproplin products, but not both. REI: 4-hour. PHI: 1day.
FRAC 49, FRAC 40.
Quadris Opti (SC) (azoxystrobin, chlorothalonil) Pepper,
Tomato | 1.6 pts. per acre. REI: 12-hour. PHI: 0-day. FRAC
11, FRAC M05.
Ridomil Gold Copper (WSB) (mefenoxam, copper
hydroxide) Tomato | For processing tomatoes: apply 1 pack
per 3.7 acres plus 0.8 lb. a.i. per acre of mancozeb. For fresh
market tomatoes: apply 1 pack per 2.5 acres plus 0.8 lb. a.i.
per acre of mancozeb. REI: 48-hour. PHI: 14-day. FRAC 04,
FRAC M01.
