GENERAL INFORMATION: Actigard 50WG is a selective, systemic
compound used for the control of downy mildew of cole crops
and leafy vegetables, bacterial leaf spots of tomatoes, and
blue mold of tobacco. Actigard 50WG is an inducer of host
plant resistance. Actigard 50WG exhibits an unique mode of
action which mimics the natural systemic activated
resistance (SAR) response found in most plant species.
Actigard 50WG has no direct activity against target
pathogens. For best performance, always follow these
directions: Actigard 50WG should be applied to plant foliage
preventively, before disease is observed in the field.
Actigard 50WG moves systemically within the plant; however
uniform spray coverage is essential for best performance.
Apply Actigard 50WG in sufficient water to ensure uniform
coverage (see specific water volumes for each crop in
directions for use tables). An Actigard application mimics
the SAR response in plants. Maximum disease control is
normally obtained 4 days after an Actigard application.
Actigard 50WG provides protection against certain diseases
in the crops listed on this label. Actigard pro-vides
sufficient protection to reduce disease levels but should be
tank mixed with other registered products with curative
activity if disease is present at the time of application,
to ensure adequate disease control or to broaden the
spectrum of disease control.
Resistance Management:
Actigard 50WG exhibits a mode of action unique from
currently available fungicides and bactericides. Since
Actigard 50WG has no direct activity on plant pathogens, the
likelihood of pathogen development of insensitivity is low.
However, plant pathogens are known to develop tolerance to
host plant resistance and to products used repeatedly for
control. Because insensitivity development cannot be fully
predicted, the use of this product should conform to
sensitivity management strategies established for the crop
and use area. Such strategies may include rotating and/or
tank mixing with products with different modes of action as
well as the use of good cultural practices. If insensitivity
to this product develops in your area, this product or other
products with a similar mode of action may not provide
adequate control. If you experience difficulty with control,
and insensitivity is a likely cause, consult your local
Novartis Crop Protection representative, local agricultural
extension office, or pest control advisor for the best
alternative method of control. Novartis encourages
responsible product stewardship to ensure effective long-
term disease control.
Some restrictions:
(1) Do not apply Actigard to plants that are stressed due to
drought, excessive moisture, cold weather, or herbicide
injury, etc.
(2) Do not apply Actigard to tobacco in plant beds or in
greenhouses/plant houses.
(3) Do not apply Actigard with foliar fertilizers and crop
oils.
(4) Avoid spray overlap because injury may result.
(5) Do not apply by air.
(6) Do not apply more than 1 oz. of Actigard per acre per
season. Allow 21 days between the last application and
harvest.
Rotational (Plantback) Restriction: Do not plant any crop
within 30 days after the last application of Actigard 50WG,
except for the crops listed below: Tobacco, leafy vegetables
including cole (brassica) crops, and fruiting vegetables.

SouthEast:
Warmer and more humid weather settled into the Ohio River
Valley this past weekend allowing late staked tomatoes to
continue to ripen. Both mature green and vine ripes are
being harvested.
Cover crops are continued to be sown on vegetable ground
recapturing nutrients and attempting to improve organic
matter. Additional weedy ground is being sprayed with
glyphosate (Round-up) in an attempt to control thistle and
Johnson grass. Cover crops will be sown later in the month
on this ground. Attempting to get a couple growers into
considering no-till pumpkins for next year planting thus
allowingthe field to remain in cover crop until June 2001
instead of the traditional plowing under of the field in
winter.
Fusarium rot is being noticed in pumpkin patches.
Amazingly, those patches that have not had vine crops in the
pass couple of years are not being affected. Continuous
pumpkin fields are seeing losses near 80-90%. OSU's
recommendation of rotating pumpkin ground so ground is
planted in pumpkins only once in every three or four years
has another believer in Meigs County.
Plans are underway for the Meigs Washington Winter Vegetable
School to be held on December 13, 2000 from 9:30a.m. to 3
p.m. at the Meigs County Extension office located at
Mulberry Heights, Pomeroy Ohio. Further information will be
forthcoming.
SouthWest:
Rains have slowed field work today ( 9/12) 1/2 to 1 inch,
and this past weekend 9/9 and 9/10, with 1/2 to 1 inch
rainfalls.
Harvest of sweet corn, tomatoes, fresh market peppers,
processing red bell peppers, cucumbers, pickles, cabbage,
green beans, 1/2 runner beans, melons, watermelons,
eggplant, summer squash, winter squash, hot peppers
continues but is diminishing in terms of supply. Shipping
point prices for most summer produce items are averaging at
or above normal. Green beans and half runners at the
Bainbridge Produce auction have been ranging from $15 to $30
a bushel with strong buyer demand. Sweet corn prices have
been ranging from $1.50 to 2.50 a dozen with strong demand.
Pumpkin harvest began about 2 weeks ago, with many chain
stores wanting pumpkins in stores early September. Wholesale
Pumpkin prices have been averaging $2 each for 13 to 18 lb
pumpkins at the Bainbridge Wholesale Produce Auction.
Harvest for retail sales began last weekend and should be in
full swing this weekend. Many miniature pumpkins are showing
severe virus symptoms in terms of green streaking and
discoloration of fruit.
Phytopthora has caused damage in pumpkin fields that have received heavy rainfalls the past 8 weeks. Powdery mildew pressure remains strong. Stink bug and cucumber beetles continue to plague untreated squash and pumpkin fields. Harvest of fall cauliflower, broccoli and cabbage fields has begun.

To gather reliable, objective information about pesticides
used on vegetable crops, the National Agricultural
Statistics Service (NASS) of the U.S. Department of
Agriculture (USDA) will be surveying vegetable growers in 21
states late this year. The Vegetable Chemical Use Survey
will be conducted by the Ohio Agricultural Statistics
Service. The information gathered from growers will be used
to set state and national estimates of producers' use of
pesticides on 34 vegetable crops.
"USDA has an obligation to provide reliable data on
pesticide use, and this survey gives NASS the information
necessary to do that," said Jim Ramey, state statistician.
Ramey added that accurate and complete responses from
farmers will provide information on which pesticides are
used and how they are used.
A local interviewer from the Ohio Agricultural Statistics
Service will contact vegetable producers over the next
several weeks to gather information on vegetable crops--
chemicals used, acres treated and rates applied. Individual
grower information is strictly confidential, and individual
reports are combined to set state and national estimates.
The survey gives growers an opportunity to tell how they use
agricultural chemicals responsibly to produce a safe and
abundant food supply. The survey results are official USDA
estimates and help to clarify the facts about chemical use
in agriculture. Accurate and timely information on actual
usage is used in the decision-making process for the Food
Quality Protection Act (FQPA) which has an impact on the
product registration, re-registration and product
alternatives.

Growers with ripe pumpkin fruit in the field should frequently check them for cuke beetle feeding on the rind if they do not plan on harvest in the near future. I have noticed some feeding on pumpkin fruit in several locations. The feeding looks like tan or buff colored scuff marks usually on the shoulders but the whole fruit can be affected making most fruit unmarketable. After feeding, the injured skin forms callus tissue and is more noticeable.
Symptoms of cuke beetle feeding on pumpkin fruit.
Closeup of fruit and beetle scarring.
Entire fruit heavily damaged with beetle scarring.
Growers should use their normal insecticide program to control late season beetle problems.
