Does
soybean cyst nematode
promote other diseases?
[OCT.
26, 2002]
URBANA — Although soybean
cyst nematode, SCN, ranks as the top cause for yield losses in
Illinois soybean fields, recent research indicates that it also
plays a role in the development and spread of other major diseases,
such as sudden death syndrome, SDS, and possibly brown stem rot, BSR.
|
"That’s bad news for Illinois farmers,
considering that SCN occurs in more than 80 percent of the soybean
fields in the state," said Terry Niblack, nematologist in the
Department of Crop Sciences at the University of Illinois. "While
SDS is fully capable of acting on its own, it now appears that SCN
hastens the development of symptoms from that disease and increases
the severity, leading to even greater yield losses."
She notes that BSR also has become more
widespread and severe in Illinois than in the past. Once again, it
appears likely that SCN has played a role in those changes
Such an interaction between the fungus
that causes BSR and SCN was not considered likely until recently,
when researchers at Iowa State University found that SCN can
actually break resistance to BSR.
"In addition, we have found that BSR is
now moving farther south in the state, at the same time that SDS has
been moving farther north," Niblack said. "Our old rules of thumb —
that BSR is only a northern problem and SDS is only a southern
problem — have been showing signs of breaking down."
To meet the challenge, collaborative
efforts are under way among researchers from the Department of Crop
Sciences and educators from University of Illinois Extension to
address the problems posed by those soybean disease interactions.
Work in the laboratory, greenhouse and the field at a number of
locations is focused on studying the interactions between SCN and
the fungi involved in SDS and BSR.
Major collaborators in the project on
SDS are plant pathologists Wayne Pedersen and Glen Hartman. Niblack
is also working on BSR with plant pathologists Dean Malvick and
Darin Eastburn. Soybean breeder Brian Diers is also contributing
resistant lines for the research project. Primary funding is
provided by the Illinois Soybean Checkoff Board.

this article]
|
"In this research, we will be looking
at how SCN infection affects the development of foliar symptoms from
SDS and BSR," Niblack said. "We especially hope to find out exactly
how and why this interaction occurs."
Another part of the research will focus
on determining whether the interaction depends on the number of
nematodes present, the genotype of the fungus, the pedigree of the
soybean variety in a field or other factors that have not yet been
identified.
"We especially would like to find out
how the disease interactions affect management practices," Niblack
said. "Growers need to understand whether it is more important to
choose a variety with resistance to the nematode or to the fungus
that causes one of the other diseases. Even more problems would
arise if we determine that all three pathogens can interact in the
same field."
Based on the research up this point,
Niblack recommends that growers with SCN and SDS or BSR in the same
field should take care of the SCN problem first by growing a
resistant variety.
"This
strategy is based on the simple fact that SCN is always present in
the field reducing yields, regardless of the environment," she said.
"At the same time, SDS and BSR do not develop every year. As the
work on this problem continues, we should come up new management
practices that will help control the problem of interaction between
SCN and other soybean diseases."

Low production may hamper
exploitation of higher prices
[OCT.
25, 2002]
URBANA — Relatively higher
grain prices compared with those in the past few years may not
offset lower yields caused by Illinois’ adverse weather conditions
this growing season, warned a University of Illinois Extension farm
management specialist.
|
"While the summer’s price upswing has
been welcomed by producers, some may find that the higher prices may
not completely offset lower revenue caused by lower yields as a
result of adverse weather conditions," said Dale Lattz. "In
addition, higher grain prices will reduce the amount of farm program
payments. There most likely will be limited loan deficiency
payments, and no counter-cyclical payments are scheduled for this
fall."
Further aggravating the potential
economic bad news is the fact that the new farm bill does not
include provisions for market loss assistance and oilseed payments
that have been paid out in the past few years.
"Higher grain prices will offset much
of the drop in farm program payments for producers with average or
above-average yields," said Lattz. "This will not be the case for
producers with a shortfall in production.
"Even for producers with normal yields,
their cash flow will be altered considerably this year due to the
drop in farm program payments. Others who had been in the practice
of prepaying expenses before the end of the year may decide not to
this year."
[to top of second column in
this article]
|
Lattz outlined the situation in a Sept.
30 report, "Cash Flows Tight on Many Grain Farms This Year Because
of Reduced Government Payments," that is part of the "Farm
Economics: Facts and Opinions" series from the University of
Illinois College of Agricultural, Consumer and Environmental
Sciences. The report is available at
http://www.farmdoc.uiuc.edu/manage/
newsletters/fefo02_18/fefo02_18.html.
He noted, however, that a significant
drop in grain prices could change the developing scenario.
"For some producers, crop insurance
proceeds will offset some of the loss in revenue due to lower
yields," said Lattz. "The drop in farm program payments also has
cash flow and income tax planning ramifications that producers need
to examine."
The full report includes tables
comparing estimated farm program payments for 2001 and 2002 for a
central Illinois grain farm. Lattz noted that differences in farm
program payments between 2001 and 2002 will vary from farm to farm
depending upon a number of factors.
"These
factors include base acres and yields for different program crops,
crop rotations, and actual yields," he said.

The next big step: a nitrogen
applicator with 20/20 vision
[OCT.
24, 2002]
URBANA — The fertilizer
applicator moving across the University of Illinois agricultural
engineering farms passed a crucial test in the past year — an eye
test.
|
U of I’s fertilizer applicator
possesses something that you don’t usually find on farm machinery.
It has a high-tech eye, a single camera mounted roughly 12 feet in
front of the boom. Researchers tested the vision sensor last year
and found that it was extremely accurate in determining whether
plants are under stress due to a lack of nitrogen.
According to agricultural engineer Qin
Zhang, the sensor’s ability to detect nitrogen stress in plants was
comparable to leaf tests using a SPAD meter.
This year, Zhang said, the goal is to
merge the sensor with variable-rate technology. The result will be a
machine that uses its high-tech eyesight to scan the plants as it
moves across the field. The resulting data is then sent to a
computer that controls the variable-rate applicator. The applicator
varies the rate of fertilizer according to the nitrogen needs of
different plants. And it does the job on the fly in real time.
As Zhang and fellow agricultural
engineer Alan Hansen put it, such machines are the next big step for
variable-rate technology.
Currently, Hansen explained, farmers
must map the field in a separate pass, either aerial or on-ground.
Then the map is plugged into a computer and used to vary the rate of
fertilizer. But there is a considerable delay between creating the
map and actually applying the nitrogen.
With this new system, the images are
taken and processed literally seconds before the fertilizer is
applied.
To determine nitrogen stress in corn
plants, the applicator-mounted sensor analyzes the reflectance of
light coming from the plants, Hansen said. But this is no easy task.
The sensor must be able to distinguish the light bouncing off the
plant from the light bouncing off the background soil. What’s more,
it must be able to do the job under all kinds of environmental
conditions.
[to top of second column in this
article] |
"If you have a cloudy day, your camera
will see the crop differently," he pointed out. Therefore, the
sensor must be able to take into account the effect of a cloudy day
on light reflecting from the plants.
According to Zhang, the variable-rate
sprayer is able to change the rate of nitrogen being applied by
individual nozzles, making it possible to vary the rate on different
rows. The key is making sure that the right nozzle hits the right
plants with the right amount of fertilizer as determined by the
on-board sensor and computer.
U of I work on this project dates back
to 1997, when it was started by professors John Reid and Shufeng Han
with funding from the Case Corporation. Zhang is now leading the
effort to create a prototype applicator by 2003 — a machine that is
fully capable of scanning the crop, determining nitrogen stress and
varying the rate of fertilizer applied, all in a single pass. This
work is being funded by the Illinois Council on Food and
Agricultural Research.
According to Hansen, the new
developments in sprayer technology may have the potential of
reviving interest in variable-rate technology. As he explained, the
first wave of enthusiasm over variable-rate equipment in the 1990s
has waned because of economic considerations.
The selling point has always been more
accurate applications with variable rates. Increased accuracy would
bring savings in chemicals, not to mention less risk to the
environment.
"But there’s still some skepticism as
to the economic benefits of this technology," Hansen said.
Since the
early days, however, the technology has become more reliable and
computing power has soared, he added. Combine those advances with an
ability to vary rates on-the-go in real time, and the variable-rate
system may eventually find itself riding a new wave of interest.

Soil temperature maps help with timing of nitrogen fertilizer
application
[OCT. 23, 2002]
Illinois farmers have a tool
to help them determine when to apply post-harvest nitrogen
fertilizer since daily maps of soil temperatures across Illinois are
available on the Web, at
http://www.sws.uiuc.edu/warm/soiltemp.asp,
from the Illinois State Water Survey, a division of the Illinois
Department of Natural Resources.
|
The maps are based on continuous
observations of soil temperatures at selected Illinois Climate
Network sites and are updated by 4 a.m. each day. "These maps serve
as a guide to general soil temperatures within a given region and
reflect existing temperature trends across the state as the fall
season progresses. Given the variability of temperatures within a
local area, it is important that farmers and applicators verify the
soil temperature of each field before applying nitrogen fertilizer
in the fall," says ISWS meteorologist Bob Scott.
The maps represent soil temperatures
observed between 9 and 10 a.m. the previous day across Illinois at a
depth of 4 inches below a bare soil surface and daily (midnight to
midnight) 4-inch bare soil maximum and minimum temperatures at the
same locations.
The Illinois Agronomy Handbook,
available from the University of Illinois College of ACES, states
that fall soil temperatures determine when ammonium-containing
nitrogen fertilizer may be applied without the occurrence of
excessive nitrification. The rate of nitrification is reduced at
soil temperatures of 50 degrees and below. Application of anhydrous
ammonia with a nitrification inhibitor can begin at soil
temperatures below 60 degrees. The soil temperature at 10 a.m. each
day is used in making the determination.
[to top of second column in
this article] |
Map users should be aware of current
soil temperatures and short- to long-term weather forecasts.
According to Scott, "Soil temperature fluctuations during fall may
result in periods with soil temperatures below the accepted
threshold for nitrogen application followed by an extended period
with soil temperatures above the accepted threshold. The date of the
first soil temperature below 50 each fall is often several weeks
before the last soil temperature above that value."
Other maps on the site show average
dates when soil temperatures drop and remain below 60 and 50,
respectively. Due to occasional periods of warm weather in winter,
the handbook does not recommend fall application of nitrogen south
of Illinois Route 16, roughly the southern third of the state.
The Web
resource, created through a grant from the Illinois Department of
Agriculture Fertilizer Research and Education program, also includes
soil temperatures at 4 and 8 inches under sod, air temperatures, dew
point temperatures, wind speed and direction, solar radiation,
potential evaporation, and precipitation in map and table formats.

Weekly outlook
Cattle
prices
[OCT.
22, 2002]
URBANA — While live cattle
prices are currently several dollars above cash prices, the latest
USDA Cattle on Feed report will provide incentives for futures to
move even higher, and cash prices are likely to follow — at least in
the short run, said a Purdue University Extension marketing
specialist.
|
"Finished cattle prices should push
into the higher $60s in November and perhaps to near $70 by the end
of the year," said Chris Hurt. "Further strength is now expected
early in 2003, as beef production finally begins to decline.
"Prices are expected to reach the
mid-$70s by late March or early April. Supplies are expected to
remain about 2 percent to 3 percent below year-earlier levels for
the remainder of 2003, with prices continuing to average in the low
to mid-$70s in the summer."
Hurt’s comments came as he reviewed the
September report that made cattle price prospects shine a bit
brighter, as the number of cattle in feedlots was down 6 percent on
Oct. 1.
"After a year of larger cattle
slaughter and heavy weights, some moderation in slaughter runs can
be anticipated by early 2003," he said. "Monthly cattle-on-feed
numbers have been 5 percent to 7 percent below year-earlier levels
since July. This means that supplies of slaughter cattle will likely
begin to drop in early 2003 and will continue to be smaller through
next year."
Prior to the report, there was an
anticipation that the number of cattle placed in September would be
up by 11 percent. However, placements were up only 2 percent. In
addition, September marketings, at 2 percent higher than last year,
were greater than pre-report anticipations. Other encouraging
information from the report was that placements of heavyweight
cattle were down. As an example, September placements of 800-pound
and heavier cattle were down 16 percent, indicating a potential gap
in fed supplies in the first quarter of 2003.
"The number on feed is lower in areas
more severely impacted by drought and higher in areas with normal or
high corn yields," said Hurt. "Drought-impact states with fewer
cattle on feed include Idaho, Kansas, Oklahoma and Texas. Iowa, with
an excellent corn crop, has more cattle on feed."
So far this year, beef production has
been up 3.8 percent. This is composed of about 1 percent more
marketings and nearly 3 percent greater weights. In the third
quarter, total production was up by 5.6 percent, with the head count
up about 3.1 percent and weights up by 2.5 percent. In the third
quarter, dairy cow slaughter was up about 11 percent, indicating a
relatively quick reaction by the dairy industry to rising feed
prices and low milk prices.
"This means that dairy cow numbers will
likely be down a few percentage points in the January inventory
report," said Hurt. "Beef cow slaughter was up only 1 percent in the
summer, as cows from drought areas in the western Plains and
Mountain States were primarily moved further east to pasture rather
than heading to slaughter."
[to
top of second column in this article]
|
Weights remain the thorn in the side of
the industry, Hurt noted. After Sept. 11, 2001, the rapid drop in
finished cattle prices caused feedlot managers to withhold cattle in
the first seven weeks after the event. By the end of 2001, weights
had risen by about 3 percent and continued to rise into March 2002,
when they were up 5 percent. During the coming year, weights are
expected to moderate due to higher feed prices and higher fed-cattle
prices. However, weights may not come down to year-earlier levels
until next spring.
"With the large beef supplies this
year, prices have been disappointing," said Hurt. "In the first
three quarters of 2002, prices for Nebraska choice steers averaged
$66.35 per hundredweight, compared with $74.83 for the first three
quarters of 2001.
"Prices have dropped about 3 percent
for each 1 percent increase in beef supplies — a large reaction of
prices to changes in supply."
For the year 2003, beef supplies are
expected to drop by about 3 percent, pork supplies are expected to
be down by 2 percent, and total poultry supplies may rise by less
than 2 percent. As a result, 2003 appears to be a year of recovering
prices and much better profit prospects for livestock producers.
The depressed live cattle market and
higher feed costs also took a toll on feeder and calf prices. In the
first three quarters of 2002, 750- to 850-pound feeder steers at
Oklahoma City averaged only $79, a full $10 below the average in the
same period in 2001. For calves, the decline was even more severe.
The price of 500- to 550-pound steer calves averaged $94 per
hundredweight, $12 below the average in the same period in 2001.
Improved finished cattle prices are
expected to be supportive to feeder cattle prices, averaging in the
low $80s in the last quarter of 2002 in Oklahoma City and improving
to the mid- to higher $80s by spring. Steer calf prices are expected
to average in the higher $90s in late 2002 before moving up to the
$103-$105 range in the spring at Oklahoma City. Prices in the
eastern Corn Belt tend to be about $3 to $5 below Oklahoma City.
"By the fall
of 2003, strong finished cattle prices and the potential for
moderating feed costs point to even stronger calf and feeder
prices," said Hurt. "Maintaining brood cow numbers, or even moderate
expansion, seems to be the most favorable management strategy."
