Auburn, Sept. 21---What a difference a year
can make.
This
time last year, many cotton producers were reeling from one of the
worst droughts on record. This year, they are breathing a sign of
relief after dodging a serious late-season threat: too much
rainfall.
Late August and early September are usually
characterized by dry weather, during which fully mature cotton
plants dry out so they can be defoliated and prepared for harvest.
That was not the case this year. Heavy rains raise
the specter of boll rot, which stems from excessively wet conditions
during late summer.
Producers even feared for a time that boll rot would
deprive producers of the drastic rebound they had expected after
weathering the severe 2000 summer drought.
Fortunately for most producers, boll-rot problems
leveled off as drier weather began setting in by mid-September.
"Right now, it’s excellent cotton weather.
Humidity is low, the air is dry and the sun is shining," says
William Birdsong, an area cotton agronomist in Southeast Alabama.
"We have incurred some damage from boll rot, but we would have
faced disaster if humidity and (tropical storm) Gabriel hadn’t
turned away."
In fact, for a time, Southeast Alabama cotton
producers tracked the movement of Gabriel with mortal dread. They
feared the storm would turn north through their region of the state,
creating prime conditions for boll rot and other moisture-related
problems and dashing hopes for a decent harvest.
As it turned out, Gabriel changed directions just in
time, sparing Southeast cotton growers major trouble.
While some early-planted cotton was affected by the
initial rainy weather, Birdsong is expecting a good harvest, barring
any other unforeseen changes in weather between now and harvest.
Even so, there have been some problems associated
with excessively rainy weather, especially in the Southwest Alabama
counties of Mobile, Baldwin and Escambia.
Hard lock, which occurs when the bolls only open
part of the way, has been a persistent problem in this region of the
state. So has another moisture-related problem that occurs when
cottonseed begins sprouting out of the bolls – a problem that has
been especially acute in west-central Dale and Dallas counties.
"With seed sprouting, the bolls just open up
and sit there," says Dr. Dale Monks, an Alabama Cooperative
Extension System plant physiologist. "Then you get plenty of
rain and moisture from hot, humid days, and the seeds (within the
bolls) begin sprouting."
Fortunately for growers in these regions, conditions
improved as dry conditions set in by mid-September.
Tennessee Valley producers also appear to have
rebounded with a few notable exceptions, says Charles Burmester, an
area Extension agronomist in Belle Mina.
"It really depends on where you go,"
Burmester says. "We’ve had pretty good conditions through
most of the valley, and in most cases, the boll-rot problem has
improved."
In Limestone County, for example, vastly improved
weather conditions have enabled producers to get back to the
seasonal chores of defoliating and even harvesting in some cases.
"Once you remove the leaves, problems
associated with moisture are reduced because there is more air
circulating around the bolls," says Curtis Grissom, Limestone
County Extension coordinator.
However, farmers in west Lauderdale County have not
been so lucky.
"Producers were talking about 2-plus bale
yields just a few weeks ago," says Ronny Lane, Lauderdale
County Extension coordinator. "Now they’re talking about no
harvest at all and collecting crop insurance for the damage they’ve
incurred from the rains."
In fact, Lane says farmers in west Lauderdale
County, where more than 70 percent of all cotton in the county is
grown, are expecting about as much as a 40 percent loss.
Ample rainfall in other parts of the Tennessee
Valley has caused regrowth on some plants, making defoliation more
difficult.
Even so, with the exception of Lauderdale County,
experts remain upbeat about the rest of the region.
"If it weren’t for what happened in
Lauderdale County, I could give you a pretty good report,"
Burmester says. "But even despite what’s happened there, we
still have good potential, providing nothing changes until
harvest."
