Georgia Cotton Scout Schools

Posted by romeethredge on April 30, 2012

Cotton Scout Schools: Tifton June 11, and Midville June 19, 2012

Cotton insect scouting schools are annually held at various locations in Georgia. These programs offer general information on cotton insects and scouting procedures and will serve as a review for experienced scouts and producers and as an introduction to cotton insect monitoring for new scouts. The annual Cotton Scout School in Tifton will be held on June 11, 2012 at the UGA Tifton Campus Conference Center. The Midville Cotton Scout School will be will be held on June 19, 2011 at the Southeast Georgia Research and Education Center. The training programs at each location will begin at 9:00 a.m. and conclude at 12:30 p.m according to Dr.  Phillip Roberts, UGA Extension Entomologist.

Interval Between Applying Direx for Burndown and Planting Has Finally Changed for Georgia Growers

Posted by romeethredge on April 30, 2012

Diuron Plantback Interval has changed according to Dr Stanley Culpepper, UGA Extension Weed Scientist.

For years, the single most common cotton question that I have been asked has been “why do we have to wait 15 days after applying Direx at burndown before we can plant cotton”.   The answer was always simple “I have no idea but that is what the label says”.  Well this week, because of tremendous support from Makhteshim-Agan (special thanks to James Whitehead), we have a new label allowing growers a 0 to 7 day plant back interval depending on production practices.  All of the needed information is provided below for the 24(c) label.

 

DIREX® 4L HERBICIDE      EPA REG. NO. 66222-54

FOR CONTROL OF MANY ANNUAL AND PERENNIAL GRASSES AND HERBACEOUS WEEDS

EPA SLN NO. GA-120001 24 (c) SPECIAL LOCAL NEED

SHORTENED PRE-PLANT INTERVAL FOR USE ON COTTON

FOR DISTRIBUTION AND USE ONLY IN THE STATE OF GEORGIA

DIRECTIONS FOR USE

 It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

 All applicable directions, restrictions, and precautions on the EPA registered label are to be followed.

 This labeling must be in the possession of the user at the time of pesticide application.

Expiration Date: December 31, 2012

 

SHORTENED PRE-PLANT INTERVAL FOR COTTON  

Apply Direx 4L at 0.5 to 1.0 quarts per acre. If strip tillage has been done prior to the application, wait 7 days after application before planting. If strip tillage has been done after the application but before planting, no plant back interval is required. Refer to the table below for use rates in preplant applications. Do not apply Direx in a preemergence application if it has been used in a preplant burndown application with this shortened plant back interval. Do not exceed suggested use rates for individual soil textures shown in the table below. If less than the maximum rate of application for a given soil is applied preplant, subsequent preemergence applications of Direx 4L may be made. However, the total combined application rate for Direx 4L applied preplant and preemergence may not exceed the maximum suggested use rate for either application method.

 

Direx 4L Alone

Soil Texture                                     Max Rate/Acre

Sandy Loam, Loam, Silt Loam, Silt      0.8 quart

Sandy Clay Loam, Clay Loam, Silty Clay Loam, Sandy Clay  1.0 quart

Silty Clay, Clay         1.0 quart

Question of the Week – Tree Swallows

Posted by romeethredge on April 27, 2012

Last week we had the birds that are often seen swooping over the wheat fields here chasing insects and they are Tree Swallows.  Hopefully they are doing some good biological control of insects for us.

This week I want to know what weed this is that a lady brought in to me to identify and what are its uses?

Cotton Planting on Dryland

Posted by romeethredge on April 27, 2012

Cotton was being planted early this week on dryland plots after last week’s rain.  This cotton that Jeffery Braswell and I were checking was about an inch deep and was in the moisture early in the week, but after heated up days and high winds, the soil is drying and he stopped planting cotton yesterday.  There are some reports of crusting on cotton planted before the rains, we are hopeful that it will emerge.

Peanut Planting

Posted by romeethredge on April 27, 2012

We are thankful for last week’s rains that are letting us plant dryland crops. Here is Will Hornsby checking behind their new John Deere twin row planters. His goal is 3 seed per foot on each twin to equal 6 peanut seed per foot of row based on 36 inch rows. He has good moisture right now but dry weather is in the forecast.  He’s planting Ga O6G variety peanuts.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

James Childree and Brandon Franklin are filling up these Cole twin row peanut planters. They run them slowly and they do well.

Dryland Pigweed Control PPI

Posted by romeethredge on April 26, 2012

In dryland cotton we often have problems getting herbicides activated in time to keep pigweed infestations from going on. Here’s info from Dr.Stanley Culpepper, UGA Extension weed scientist, about incorporating some of our Reflex herbicide before planting.

Problems with Bermuda Pastures and Hayfields

Posted by romeethredge on April 25, 2012

Bermudagrass Decline Issues according to Dr.Dennis Hancock, UGA Forages Scientist


We have seen a LOT of poor spring green-up in bermudagrass in the Southeast. Almost the exact same scenario is showing up all over Georgia, Alabama, and North and South Carolina (that I know of, and I’m sure it is happening elsewhere, too). There are several issues that are at play here.

First… Poor spring green-up in bermudagrass is usually a combination of several causes + one “straw that broke the camel’s back.” Usually, the biggest issue is the soil test K values are marginal (and in the subsoil it is almost certainly REALLY low). When this is combined with a low soil pH (which even for bermudagrass should be > 6.3 for best results), the plant becomes extremely stressed. K is critical to plant vigor, stolon and rhizome health, drought tolerance, winterhardiness (which should also be thought of as spring emergence), and disease resistance. Given the cadre of problems we’ve had in the past several years (drought, late freezes, high pest pressure, and greater disease incidence), it is a wonder that the bermudagrass growing in even extremely fertile sites isn’t having problems. So, really, it shouldn’t be a surprise that bermudagrass is suffering in less fertile sites (but it is a surprise, even to those of us who see this all the time).

A common situation is that “the straw that broke the camel’s back” this year was a dormant spray on the bermudagrass… only, the bermudagrass wasn’t very dormant.  This additional stress, when it is in its most vulnerable state (i.e., when breaking of winter dormancy), is enough to push it over the edge. Burning it back with a herbicide (even one like paraquat that doesn’t translocate) at that stage will sting bermudagrass SEVERELY. Research in the turf world suggests that using just 1 pt of glyphosate on bermudagrass during a “dormant spray” can cause severe spring stunting if the bermudagrass has >10% green-up at the time of application.

However, let me emphasize… the later is just the straw that broke the camel’s back. Had the soil fertility been in good shape, the lack of spring green-up would be very short term.

If you have a stand that has not yet greened up, you may be asking yourself the “well, what do I do now?” question. The only reasonable thing to do now is wait. No, check that… if the pH is off, add the recommended lime and then wait. If it is needed, the sooner the lime goes out, the better. If the bermudagrass has begun to show some signs of green-up, address the soil pH and K deficiencies. Put out K at a 1:1 ratio with the N. No shortcuts. No excuses. K is a heck of a lot cheaper than re-sprigging.

If the stand is still struggling to emerge (i.e., little or no signs of emergence) begin making plans to replant or rotate out of bermudagrass for a year or two. There is a very real possibility that this stand is now dead. You can put it to a little bit of a test by digging a few plants and looking for green (or at least white) tissue at the plant base/crown. If it is brown or decomposing, that plant will not recover. If more than 50% of the plants you dig aren’t going to recover… well, the good news is you’re going to get a chance to incorporate your lime and fertilizer. If it doesn’t green up by the end of April, then it is dead. Sorry, there’s nothing for it.

Question of the Week – Palmer Amaranth

Posted by romeethredge on April 19, 2012

Palmer Amaranth is the weed that was blooming when very tiny. It’s quite adaptable and will grow differently depending on several factors.  It’s very common with short photoperiod times during late fall or very early spring for it to bloom early.

See my other post today concerning pigweed for more info.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This week my question is about these birds. They are often seen swooping in wheat fields like these are.  What are they?

Later,

Wheat – Some Falling

Posted by romeethredge on April 19, 2012

Wheat has been falling (lodging) for a month or more in parts of fields. This is sometimes due to too much Nitrogen fertilizer and some varieties have been more susceptible to it in the past, but this year there is more going on and some is falling that I know doesn’t have excessive N.

I asked UGA Grains Scientist, Dewey Lee, about it and these are his comments.

“You can cite so many events and reasons for the wheat lodging or falling this year.  Which one is the majority portion of the equation….who knows.  Warm winter, high tillering rate, thin cell walls, too much N uptake, rapid growth, cold damage, variety characteristics, high winds, …….they all contribute in some form or fashion.

The yield penalty will be dependent on how mature the crop is and the degree of lodging.  Though there is no way I can tell, I expect the scenario to follow previous years.  As the crop matures to grain fill, the less it will stand up and the greater the test weight loss.  The more the grain has filled prior to lodging, the less yield impact (except test weight) lodging has on the plant itself.  However, field losses are greater simply due to harvesting difficulties. Plants in fields where lodging took place earlier this year stood back up to about a 45 degree angle and most likely will suffer some loss.”

Here's an aerial photo of wheat that has fallen. Thanks to Wade Spooner.
