Pumpkin disease management begins with cul-
tural and preventative controls such as proper site selec-
tion, field preparation and the use of resistant varieties.
Some of the most effective alternative control measures
include planting in well-drained soils on open sites with
good air circulation, away from early cucurbit crops such
as summer squash that may spread diseases, using pow-
dery mildew-resistant varieties, and using deep zone
tillage to improve soil drainage and protect fruit from
rots.
Fungicide Program: Recent experiments at
UConn showed that unsprayed pumpkins yielded less
than half as much as plants with an effective fungicide
program. There are four common and important diseas-
es* you can help manage with a good fungicide pro-
gram: powdery mildew, Plectosporium blight (Plecto),
black rot (BR) and downy mildew. Powdery mildew
(PM) tends to be the most common and the most im-
portant in many years, so we design the spray schedule
around it. The basic idea is to slow disease spread with
the fungicides by limiting spore formation, new leaf in-
fections, and stem and fruit problems, so that you max-
imize your yields and net profits.
To determine when to make the first application
2014 PUMPKIN FUNGICIDE PROGRAM

for PM, scout 50 lower leaves each week after the
plants run, and spray when you find the first small,
round, colony of white powdery mildew spores (usually
on the underside of the leaf). Then, continue to make
applications at 10-day intervals until mid-September.
Systemic fungicides, which move through the
plant or leaves, usually provide the most effective con-
trol of PM because it is impossible for any sprayer to
provide good coverage where the infection first occurs:
on the underside of the lower, older leaves, in a waist-
high pumpkin patch. As part of your PM resistance
management strategy, use each systemic family/group
only one time each season. Unlike protectant fungicides
that have several modes-of-action to stop infection,
systemics tend to have a single mode-of-action which is
easily skirted by the billions of spores encountered by
the product. Add a protectant fungicide to the tank mix
during each application to help slow resistance, and to
provide control of Plecto and BR on fruit.
Currently, there are four effective systemic
groups to choose from for PM control: fungicide re-
sistance groups 3, U6, 7 and 13. So, if you choose one of
the most effective products from each resistance group,
your spray program in 2014 should look something like
this: Torino (U6) + Bravo (i.e. chlorothalonil), Quintec
(13) + Bravo, Procure (3) + Bravo, Pristine (7 & 11) +
Bravo, and then switch to a mix of two protectants for
the remainder of the season (sulfur + Bravo). This pro-
gram uses the most effective systemic groups early in
the disease cycle to restrict spread, and the less effec-
tive later. You could also skip the Pristine application
because it is the most expensive, or mix the Pristine
with a protectant such as sulfur or Dithane, to rest the
Bravo, while still providing good protection against PM,
Plecto and BR. Group 11 products are the most effec-
tive against Plecto if it becomes the major concern in
your field.

NEWA: A NEW FREE MANAGEMENT TOOL FOR CT FRUIT GROWERS
Continued on page 6
By Mary Concklin, UConn Extension Educator, Fruit Production & IPM
We have a new management tool available to fruit growers in CT that you should find very useful with crop
management decisions including irrigation, fruit thinning and pest management. The NEWA system (Network for En-
vironment and Weather Applications) began in New York in 1995 and has evolved to remain current with advances in
pest and weather forecasting. There are 22 weather-based IPM forecast models implemented in NEWA. It is operat-
ed by and funded through the NYS IPM Program and collaborates with the Northeast Regional Climate Center
(NRCC), Department of Earth and Atmospheric Sciences. Weather data is collected via Ethernet from weather sta-
tions on the ground, archived and run through quality control routines prior to calculating and displaying degree day
accumulations and IPM forecast models.
At UConn we were very fortunate to have
received a grant to purchase and install weather sta-
tions this year and link into the NEWA system at Cor-
nell. There will be 41 stations on-line very soon. Pres-
ently there are 16 stations on farms across CT with an
additional 8 to be installed; of those, 2 were pur-
chased and installed by Rogers Orchards last year but
not hooked up to the NEWA system until now, and
one station has been at Lyman Orchards and on
NEWA for several years through a UMass grant. Six-
teen weather stations will be installed at schools.
UConn has had a weather station at the research
farm and that has also been linked to the NEWA sys-
tem. You can access any of the stations free of charge
from your Smartphone or computer by going to
www.newa.cornell.edu.
This system uses interactive insect and dis-
ease forecast models that will automatically compute
and display information beneficial in IPM (organic
and non-organic) decisions. NEWA provides hourly
and daily weather summaries including leaf wetness,
a wide range of degree day tables (which are inter-
preted in the individual insect models), plant disease
forecasts for apple and grape (vegetable and turf as
well) including ascospore maturity charts important
for apple scab decisions, and insect models for apples
and grapes. By using this information to help deter-
mine timing to begin scouting for particular pests
(driven by degree days and weather forecasting), as
well as timing of pesticides applications, growers can
save on pesticide costs. Insecticide and fungicide Photo: Mary Concklin
In the last issue of ‘Crop Talk’ I mentioned that
“there is a computer model (Tom-Cast), based on temper-
ature and leaf wetness time, that can help predict early
blight (EB) infection periods”, as well as Septoria leaf spot
(SLS) and Anthracnose ripe rot (ARR) on tomatoes. There
is actually a second blight cast model (Simcast) that can
help time sprays for late blight (LB). I also said that I was-
n’t a big fan of these models for predicting when to apply
fungicides because scouting has proven itself to be more
reliable over time and capable of alerting you to the pres-
ence of pests that the models can’t. However, I tend to
be a low-tech type of guy…I don’t even carry a cell phone!
Some of you high-tech folks may actually want to monitor
disease development with computer models, and thanks
to Mary Concklin (UConn Fruit IPM) and the folks at Cor-
nell University, you are in luck.
Cornell has set up the Network for Environment
and Weather Applications (NEWA) which provides the
weather data from nearby farms throughout the North-
east to all network users and runs the models for you.
Mary and other members of UConn’s IPM team received a
large grant from USDA EIPM, that allowed her to set up a
network of 41 weather stations here in CT, located at
farms and schools, that are now (or soon will be) linked to
the NEWA system (at least for 2014). This means that
there is now local weather data from locations near you,
and the model predictions from nearby sites should apply
to your farm. How much easier could it be?!!! You don’t
even have to buy and run a weather station, deal with all
the electronic headaches, or pay to link into NEWA (UConn
IPM pays one price for the state to participate). All you
need is an on-line computer and you can get the infor-
mation for free!
Another nice feature of this system is that it will
run degree-day insect development models for certain
pests, such as cabbage and onion maggots, which can help
you determine when each generation of the pest should

occur this year, thus allowing you to more accurately
time your scouting and control procedures. I should
mention that the Tom-Cast and Simcast models also
work for potatoes, because they too have problems with
early and late blight. The site can also help you with on-
ion diseases, downy mildew on cucurbits, and Stewart’s
wilt of corn.
I could just tell you that all the information
about how all these different models work, and how to
interpret them to help time your control procedures, is
available on the NEWA site (www.newa.cornell.edu), but
I’ll give you a little summary of the Tom-Cast, Late blight
and degree day models to entice you into looking at the
site (in case you’re a low-tech type of person like me).
Tom-Cast for timing fungicide applications for
EB, SLS and ARR: This model starts with a caution that it
should not be used if you have a bacterial disease
(canker, spot or spec) in your plantings because the fun-
gicide spray intervals recommended will be too long for
copper (the best bactericide). As mentioned, tempera-
ture and leaf wetness duration are used to calculate dis-
ease severity values (DSV’s), and when you accumulate
enough DSV’s at your site you make a fungicide applica-
tion. For example, it might take only 3-5 hours of leaf
wetness at the near-optimum temperatures for disease
infection of 69-77oF to produce one DSV, while it takes 4-
8 hours between 64-68oF or 78-85oF, and 7-15 hours be-
tween 56-63oF to produce 1 DSV. You can also accumu-
late 2, 3 or 4 DSV’s in the 69-77oF range, or any other
range, with longer wetting periods up to 23 hours. But
you don’t have to worry about that part. The machine
calculates the DSV’s and keeps a running count by date.
You spray for the first time when it accumulates
25 DSV’s starting at transplanting, and then every 20
DSV’s after that if you’re using Bravo, Quadris or Cabrio,
and every 15 DSV’s if you are using a mancozeb-type
product (i.e. Dithane or Manzate). Make an application
IPM SERIES: USING FORECASTING MODELS TO TIME TOMATO FUNCIDICES (AND
INSECT MANAGEMENT)
Continued on next page
IPM SERIES: FORECASTING MODELS (CONTINUED)
Page 5 VOLUME 10 , NUMBER 2, APRIL 2014
just before the next rain if the spray interval is longer than
14 days. Also, make the first application by July 11th if you
haven’t accumulated 25 DSV’s by then.
To use the Tom-Cast model, start by going to the
tomato disease page and read a little about the model.
Then, at the top, select “Pest Forecast”, then on the drop
down menu choose “tomato diseases/Tom-Cast”. Fill in the
date you are interested in and select the CT site nearest to
you from the drop down list. It will provide you with sever-
al columns of data, but the one you are interested in is the
accumulated DSV’s. Note: there is nothing accumulated for
2014 yet, so you will have to choose i.e. June, 2013, Mid-
dlefield, CT (where they had a station running last year) to
see a page of site specific data.
Simcast for timing fungicide applications for late
blight: The LB model is slightly more complicated using
both “Blight Units” to indicate disease severity and
“Fungicide Units” to indicate when your fungicide protec-
tion runs out. It assumes you’re using a chlorothalonil-type
product, such as Bravo, unless you enter a different prod-
uct. It also takes into consideration how susceptible, toler-
ant or resistant your tomato variety is to LB.
To use Simcast, choose the Simcast model instead
of Tom-Cast, then, enter the weather station site nearest
you, the date of your last fungicide application, and your
tomato variety from the drop down list of choices. If your
variety is not on the list, or you have a mix of varieties, as-
sume it is, or they are susceptible, and enter that. Then hit
the “get report” button and you will see accumulated Blight
Units and Fungicide Units by date. The units (numbers) will
turn red when the spray threshold is reached.
Degree-day models for insects: Degree-day mod-
els are a way to predict pest or plant development based
on temperatures. In its simplest form, the degree-day cal-
culation uses the average daily temperature (maximum +
minimum/2) minus the pest’s minimum development tem-
perature (base temp). So, cabbage maggot begins to re-
sume growth or development at 4oC and onion maggot at
40oF. For example, for cabbage maggot, a day in March
might have a high of 8oC and a low of 2oC (8+2/2 =5) mi-
nus base 4oC, would result in just 1 DD accumulating on
that date. The NEWA system actually uses a more accu-
rate degree-day model based on algorithms, but again,
you don’t have to worry about calculating degree-days,
because the NEWA system will do it for you, and just
show you how many have accumulated this year or since
the last generation of the insect.
So for cabbage maggot, the overwintering gener-
ation will start to produce the first adult flies after
161DD. The first generation flight will peak at 251DD and
end at 449DD. You want to apply the first application of
cabbage maggot fly bait (i.e. Seduce) just after 161DD, or
a drench before peak flight because the eggs will begin to
hatch by then. The second, third and fourth generation
flights will end 508, 465 and 399DD after the proceeding
generation. The NEWA system recommends you reset
the accumulating degree days to zero at the end of each
generation’s flight to help keep track of the next genera-
tion. Usually we only have to treat during the first flight
because soil temperatures later in the season will nor-
mally be above 90oF, which will kill the eggs and hatching
maggots (unless prolonged rainy periods suppress soil
temperatures while transplanting later plantings).
To use the degree day models, just choose “pest
forecast” at the top of the page, and “cabbage maggot”
from the drop down menu. Then choose the closest
weather station site from the drop down menu and it will
provide the accumulated DD by date. At this time, you
can’t access the data for the previous year (i.e. 2013) for
the vegetable insects, as you can for some of the fruit
insects, so you can only compare this year to last year for
some insect pests. However, Cornell will be working to
improve the site in the next year or two, so you should
see improvements as you use the system.

charts with information on organic and non-organic
materials, as well as bee toxicity are also on this site
under individual models.
In addition to pest management, the NEWA
system includes information on apple irrigation, fruit
thinning using the carbohydrate model, and critical
temperature charts for tree fruit.
Irrigation timing and amounts of water to
apply can be figured out using the Apple irrigation
section located under the “Crop Management” cate-
gory located along the top menu bar. Choose a
weather station near you on the drop down tab on
the left column. You will need to fill in the blanks and
then hit the calculate button. If you irrigate, add the
number of gal/acre applied and hit calculate again.
This will help you determine the amount of water
needed over and above the rainfall that was received.
The Apple carbohydrate thinning model is
fairly new and is based on the amount of carbohy-
drates in the trees and the impact they have on thin-
ners. Sunny days with cool temperatures lead to reduced
natural drop and less response to thinners while cloudy
days with hot temperatures result in carbohydrate deficits
which leads to a stronger response to thinners. I would sug-
gest you try this model on a small scale and not your entire
orchard until you feel very comfortable with it.
Find a weather station close to you on the drop
down menu and check out the valuable information this
system provides. Note that we are still early in the season
and the more model specific information will be available
as we move into the season.
If you have any questions on how to use this sys-
tem throughout the season, please contact me at
[email protected] or at 860-486-6449.
As you make plans for 2014, you should evaluate the adequacy of your 2013 risk management plan for each segment of your farm
business. USDA offers risk management programs that can help you to manage your risk exposures and secure operating loans.
They include crop insurance available from crop insurance agents (list available at: www.rma.usda.gov/tools/agent.html) and the
Non-insured crop Assistance Program available from the Farm Service Agency (FSA/USDA) serving your County. For more infor-

Since this fungicide program is ineffective against downy
mildew (DM), you usually need to add another mobile fungi-
cide to your spray mix late in the season when (or if) this
disease shows up. DM first appears as widely scattered, yel-
low spots or ¼-1/2 inch, yellow or brown squared-off spots
on the leaves. If more than one DM application is needed,
alternate between two effective products to slow resistance.
Some of the more effective downy mildew products include:
Ranman, Presidio, Previcur Flex, Revus, Tanos, Curzate, and
in some years Dithane or a phosphorus acid-type material
such as ProPhyt. You can also mix sulfur (protectant) and
Tanos (systemic) to control all four diseases. Organic grow- Plectosporium on a pumpkin. Jude Boucher photo.

ers can mix sulfur for PM control with other broad-spectrum products (i.e. Double-Nickel) to minimize fruit rots and
defoliation from DM.
*Recent research shows that you can also reduce problems with Phytophthora blight using preventative soil
and foliar applications of certain fungicides (see ‘Chemical/Microbial Control of Phytophthora Blight’ – this issue).
However, effective chemical control of all five pumpkin diseases may be cost prohibitive.
Page 8
Page 9 VOLUME 10 , NUMBER 2, APRIL 2014
Phytophthora blight (Phyto), also known as the plant destroyer, is the toughest vegetable pest there is, because unlike
other diseases where you generally start with a clean slate each year if you rotate, Phyto will survive for decades, and is a monster
to manage!
Years ago the soil-applied fungicide Ridomil Gold (mefenoxam) provided pretty good control of Phyto on susceptible hosts
such as solanaceous and cucurbit crops (e.g. peppers and summer squash). However, when there is only one chemical option to
control a pest, with constant exposure, it often doesn’t take long for resistance to become a problem. Today most of the Phyto
strains in the Northeast are highly resistant to Ridomil.
Now, recent research from Michigan, and other states, is showing that the old approach of applying some of the newer
fungicides directly to the soil as transplant drenches, or as soil drenches at or after planting, or through trickle irrigations sys-
tems, can substantially reduce the number of plants that die from the crown rot phase of the disease, leading to higher overall
yields. When foliar and fruit infections are also a problem, follow-up foliar applications have proven to be effective. Researchers
recommend making foliar applications with three noz-
zles per row, with the outer nozzles angled in at 45 de-
grees, and with 50 g.p.a. of water so that the product
covers and runs down the stem to protect the plant
crown and roots.
I can’t call these preventative soil and foliar
applications IPM, because one of the principles of IPM is
that you never make preventative pesticide applications
(applications are made only after detecting the pest and
reaching an action threshold). However, the scientists
conducting this research, and most of the fungicide la-
bels, still insist that you need to combine the use of
these chemical controls with the use of cultural controls
and (when possible) resistant varieties as part of an IPM
system.
Cultural controls include strategies such as
avoiding planting susceptible crops in infested soil, limiting the spread of the pathogen to clean fields, and any number of water
management techniques that reduce soil saturation. Some of these include: avoiding planting in low wet holes or areas that will
flood sometime during the season; using raised-beds to reduce soil saturation; aligning the beds with the natural slope of the field
to allow water to run out from between beds; breaking the beds at low points to allow water to leave the field through its natural
course; sub-soiling or zone-tilling to break plow pans and improve drainage both before building beds and between beds after they
are built. Also, you should rogue out sick and dying plants early in the disease cycle so that the pathogen doesn’t spread down the
rows or to adjacent rows.
Some of the newer fungicides that show varying degrees of promise as soil treatments or follow-up foliar treatments in-
clude: Presidio (fluopicolide, resistance group 43), Zampro (ametoctradin + dimethomorph, groups 45 & 40), Revus
(mandipropamid, group 40) and Ranman (cyzofamid, group 21). Presidio and Ranman have supplemental labels that allow drench
or trickle irrigation applications, while Zampro allows these types of soil applications on the main label, but Revus can only be ap-
plied as a foliar treatment. Supplemental labels are available on the CDMS web site (www.cdms.com) and must be in your posses-
sion when soil applications are made.

They have even tested some experimental chemicals (i.e. oxathiapiprolin and others) from different companies that pro-
vided 100% control in field trials when soil applied. Time will tell if these new chemicals receive registrations. If they do get regis-
tered soon, they will help provide options to alternate with to slow resistance so that we don’t repeat what happened to Ridomil.
Labels on all these products limit their use to 3 to 6 applications per season, require alternating between products from different
resistance groups, and call for tank mixing with another product or a surfactant to help combat resistance (see table). These label
restrictions, while extremely important to prevent resistance, make it challenging and expensive to design a spray program that
will protect your crop throughout the season. Here are some effective ways to use these products to fight Phyto.
Of the registered products, soil applications at planting (drenches) of Presidio, followed by foliar sprays of Revus + cop-
per, alternated with Presidio + copper, on a 7 to 10 day interval seems to be the most effective. In 2012 and 2013 trials in MI,
this or similar spray programs completely eliminated, or dramatically reduced, plant death on peppers and produced the highest
yields in the trial. Similar results were achieved on summer squash. When they tried the same type foliar spray programs without
the Presidio soil drench at planting they didn’t work nearly as well.
Transplant drenches of Zampro or Ranman, followed by foliar programs that alternated between products, produced in-
termediate results in the MI studies. So, if you wanted to use an effective all-soil-applied program, you could start with Presidio
at planting, and then alternate every 7-1O days between Zampro, Ranman and Presidio. The Ranman cannot be applied through
a drip system, so it could be put on as a drench with a backpack or boom sprayer. You could also use these same three products
as foliar applications after an initial soil application of Presidio, but the foliar Presidio must be applied with another product for
resistance management and the Ranman and Zampro must be applied with a silicon or non-ionic surfactant. I think you can see
how this program can get expensive. However, don’t think about just using a single drench at planting, because that didn’t work
any better than the untreated control plots in these studies.
What about Microbial products? In one study with summer squash drench applications of either Presidio, BioTam
(Trichoderma asperellum and gamsii), Serenade Soil (Bacillus subtilis), or Actinovate AG (Streptomyses lydicus), applied to the soil
at planting and then every 14 days, the three microbial products reduced plant death by about half compared with the untreated
control plots and improved yields by 3 to 4 fold. Presidio again performed best by reducing plant death by about 85% and improv-
ing yields by about 5.5 fold (Note: this was for experimental purposes, the label does not allow more than 2 sequential applica-
tions). When Presidio was alternated with any one of the Microbial products every 14 days, they did about as well as the Pre-
sidio alone, but with the added advantage of having a resistance management component to the program and less overall
chemical usage.
Most of these studies were conducted by Dr. Mary Hausbeck and her students Rachel Naegele and Charles Krasnow at
Michigan State University. Thanks to Meg McGrath for sharing the results of several studies from different researchers.
