Iowa Bull Clinics: Selection Decisions 2005
The commercial bull selection process continues to be one of the most
important decisions made in a beef operation. However, you can be
overwhelmed with the abundance of expected progeny differences (EPD's) and
gene markers as you try to find the right bull to fit your herd and meet new
market demands. The Iowa Beef Center at ISU is hosting Bull Clinics:
January 18, 1-4 p.m., Cronk's
January 19, 12:45-3:45 p.m., Clay County Regional Events Center
The meetings will address three
questions: What kind of cattle should be produced in the next 3 to 5 years?
How and when should DNA and gene markers be used? How do you target the
EPD's for bull selection?
With more and more EPD's, producers
are struggling with selecting the EPD's most important in their breeding
programs. A new computer sire sort program will be demonstrated. This
program can help producers develop breeding program goals and selection
decisions for their own herds.
Fee ($15/person at Denison and $20 /person at Spencer) to be paid at the
door. For a brochure, contact Dennis (712-336-3488), Beth (712-472-2576),

Fixed-timed estrus synchronization systems are one of the hottest topics
today with progressive cow-calf producers. These systems allow a producer
to breed cows on an appointment basis. The Iowa Beef Center (IBC) is
offering a webcast program to discuss fixed-time estrus synchronization on
January 27, 7-9 p.m. The program can be viewed at the following NW Iowa
Emmet Co Extension Office, 26 S 17th St., Estherville
Humboldt, Co Extension Office, 727 Sumner Ave
Ida Co Extension Office, 207 Main St., Ida Grove
O'Brien Co Extension Office, 340 2nd St. SE, Primghar
The program will also cover new
methods of estrus control, a hands-on demonstration of IBC's new "Estrus
Synchronization Planner" software, and breeding female evaluation for synch
systems. The software (available for purchase) offers 22 estrus
synchronization systems, recommendations of various systems for cows and
heifers, a daily calendar of activity and a budgeted cost analysis of the
various synchronization systems. Registration fee for the webcast is $15
per person. For more information, contact Dennis, Beth or a county hosting

Northwest Iowa Sheep Producers annual meeting will be held January 3 at
Pete's Steak House, Hartley. Special speaker will be Dr. John Thomson, DVM,
newly appointed Dean of the Iowa State University College of Veterinary
Medicine. Registration begins at 6 p.m., leg of lamb dinner at 6:30 p.m.
Price of meal is $5/person with reservations due to Arlene Meerdink at
Selecting Breeding Stock
over 35 years, sheep genetic research at MARC has emphasized the evaluation
and use of breed resources. A total of 19 breeds and 3 composite flocks
provide an extensive range of performance for economically important traits
such as survival, longevity, seasonality, puberty, conception, prolificacy,
growth, carcass merit and meat quality.
Commercial sheep production profitability and efficiency could be improved
markedly by greater industry use of EPDs from NSIP genetic evaluations. Dr.
Kreg Leymaster, Research Geneticist; Roman L. Hruska, U.S. Meat Animal
Research Center, Clay Center, Nebraska; Dr. Dan Morrical ISU Extension Sheep
Specialist; Mr. Jerry Sorensen, West Cyclone Farms; Harlan and Dennis
DeWitt, ISU Extension Livestock Field Specialist, Spirit Lake will be
providing information for producers to "Select Breeding Stock for
Economically Important Traits." The program will be on Thursday, January 20
at Pete's of Hartley, Iowa. Pre-registration of $20 is due by January 17.

Lambing Time Workshop
Tuesday, January 25 will be the Lambing Time Workshop in the Lambing
barn of Mark and Lori Loutsch, LeMars. There will be two sessions, one
beginning at 1:00 p.m. and the second at 6:00 p.m. For sheep flock
biosecurity, reservations are required by contacting the Plymouth County
Extension Office 712-546-7835. Cost is only $15/person with balance being

Iowa Pork Congress
Weiss - ISU Extension Swine Field Specialist
Iowa Pork Congress will have a new look this year as well as a lot of good
information relating to the pork industry. The Congress will be held
January 26 - 27, 2005 at the Iowa Events Center, a newly constructed
facility that is connected to Veterans Memorial Auditorium in Des Moines.
Show hours will be Wednesday, January 26, 9:00 a.m.- 5:00 p.m. and
Thursday, January 27, 9:00 a.m.- 4:00 p.m. The trade show will consist of
over 300 companies in nearly 500 booth spaces located in the new exhibit
Seminars will begin both days at 10 a.m. Topics are: Environmental Issues,
Swine Health, Meat Quality, Employee Management, Sow Productivity, Market
Information, Feed Mill Management, Managing Finishing Pigs, and Weaning Age.
There will also be other company sponsored seminars.
Many of your ISU
Extension State and Field specialists will be there to visit with you and
answer any questions you may have. See you there.
Asian Soybean Rust -
What Do We Need To Do Now?
by Paul Kassel, ISUE Crops Field Specialist
1. Consider available
fungicides. Fungicides that we need to use are classified as preventative or
fungicides are applied to the foliage of the soybean plant before the spores
of Asian rust germinate. This would be somewhat analogous to applying a
pre-emergence herbicide to the soil to prevent weeds from germinating. The
preventative fungicides include Headline and Quadris in the class of
fungicides called strobilurins. The strobilurins inhibit spore germination
and need to be applied prior to infection. They are not systemic (do not
move within the plant). Headline and Quadris have a full federal label.
fungicides are applied to the foliage of the soybean plant and actually kill
the ’body’ of the Asian soybean rust fungus. This would be somewhat
analogous to applying a post-emergence herbicide to kill emerged weeds in a
crop. Curative fungicides include Folicur, Laredo, and propiconazole (propiconazole
is Tilt, Bumper, PropiMax and others). Folicur, Laredo and Tilt are in a
class of fungicides which are called triazoles. The triazoles kill the
vegetative part of the fungus, but have no effect on spore germination. They
are systemic products, to a certain extent. Folicur, Laredo and Tilt have
section 18 emergency labels.
Combination products include Stratego and Pristine. Stratego is
expected to receive a section 18 label before the 2005 season. Stratego
contains a triazole and a strobilurin, therefore it offers the advantage of
preventative and curative mode of actions.
2. Consider your spray
requires relearning of the application of contact products. The
strobilurins have limited systemic activity and therefore good coverage of
all soybean foliage is essential for the chemical to be effective. The
triazoles are more systemic, but still require good spray coverage.
Application of a
fungicide requires spray pressures and nozzles that provide a lot of very
small droplets. Most of the fungicide labels suggest 10 to 20 gallon per
acre carrier volume and spray pressure “for adequate coverage and canopy
penetration.” Other labels are less specific, suggesting only to use
sufficient water and pressure to ensure adequate coverage.
This means that most
farmers will want to apply 15 to 20 gallons per acre of spray mix at 30 to
40 PSI pressure. Twin-jet nozzles are preferred, but flat fan nozzles can
also be used to ensure adequate coverage of the soybean plant. Nozzles and
pressures that have been used for glyphosate (Roundup) herbicide
applications will not provide adequate spray coverage.
It is difficult to
predict when fungicide applications will be needed. It is possible that a
first application may be needed in the first part of July and then possibly
again in August. The July application will likely be easily accomplished
with the sprayer that most farmers already own. The August application will
likely require more crop clearance. High clearance tractor tires, and/or
sprayer tires may be needed to avoid damage to the soybean crop. Otherwise
the second application may need to be custom applied.
Aerial application will
be an option also. Labels for the above mentioned fungicides describe
aerial applications. Aerial applications of fungicides, at first, may seem
to be inadequate in terms of spray coverage, but experience with
aerial applications with other contact
products have proven very satisfactory.
3. Consider the
following decision timeline.
The potential severity
of Asian soybean rust will not be known until next spring. By March of
2005, we should have a pretty good idea of how well the Asian soybean rust
over-wintered in the southern United States. That will give us an idea of
the potential amount of the spores that may be available to be delivered to
the upper Midwest.
By April and May we will
have information on the incidence of Asian soybean rust in the soybean crop
in the southern US. There also will be some predictions on the likelihood
of weather conditions that would bring the rust problem to the upper
Therefore, by soybean
planting time in northwest Iowa, we will have some idea of the potential for
Asian soybean rust. While these may be largely predictions based on weather
conditions, it should allow us time to react to a problem that requires
fungicide applications in early July.
Manure Applicators Meetings
