Assessing the Impact on the Southeast Alabama Cotton Crop from Hurricane Irma
on 9/28/2017 1:20 PM
Category:Agronomy Series

​Hurricane Irma came through Southeast Alabama during September 10th and September 11th, 2017.  After the storm passed through it was obvious that the Cotton crop was to bear most of the damage from this storm.  During the storm in Southeast Alabama, wind speeds ranged mostly from 30 to 35 miles per hour.  However, I have heard of some reports of 50 to 65 mile per hour gusts being recorded. We are very fortunate that the cotton crop was not impacted any more than what it has been from Irma.  However, the consensus from my observations and grower input is that the negative impact from Irma is a loss of around 50 to 100 dollars an acre.  This is from cumulative impacts as described in the summary. Certainly this is damaging to our Cotton farmers, who exist on narrow margins to begin with.

Potassium Deficiency in Cotton Production
on 9/20/2017 12:18 PM
Category:Agronomy Series

Potassium is a Macronutrient, which means that the nutrient is needed by the plant in larger quantities. ie over 20 pounds per acre of the nutrient for plant production. Potassium (K) is an essential nutrient for normal plant growth and development, which plays a particularly important role in fiber development. Potassium defi­ciency results in decreased fiber quality and lowered yields. If K is limited during active fiber growth, there is a reduction in the turgor pressure of the fiber result­ing in less cell elongation and shorter fibers at maturity. Anything which restricts root growth, such as disease, insect damage, nematodes, root pruning, poor drainage, soil acidity, or compaction, reduces nutrient uptake and may increase K deficiency. Information about recognizing K deficiency is described in the attachment.Potassium deficiency in cotton TI.pdf

Disaster Preparation for Livestock Operations
on 9/6/2017 9:30 PM
Category:Animal Sciences Series; Disaster Recovery Series

Due to the vulnerability of Alabama to hurricanes and their potential to cause widespread damage due to high winds and flooding, disaster preparedness is essential for livestock operations. Advanced planning can help producers minimize the loss of animal lives and the health problems associated with disasters. Although help may be available from many sources following a disaster, producers themselves are ultimately responsible for the welfare of their animals and should prepare accordingly. At the end of the attached Timely Information Bulletin is a checklist for livestock producers to consider when preparing for a potential disaster such as a hurricane.

Potomac Horse Fever recently diagnosed in Alabama
on 7/19/2017 11:37 AM
Category:Animal Sciences Series

Potomac Horse Fever (PHF) was originally identified in the late 1970's as a disease affecting horses in the eastern United States near the Potomac River. However, since then, the disease has been diagnosed in other locations in the United States and Canada, but never in Alabama until recently. This summer, PHF was diagnosed in Alabama horses that had not travelled to regions typically associated with PHF, indicating natural transmission of the disease in Alabama. Potomac Horse Fever is a potentially fatal disease for horses, but is curable if treated early. The attached Timely Information Bulletin contains additional information about PHF to help protect horses from this potentially deadly disease.

Sulfur in Cotton on Sandy to Sandy Loam Soils
on 7/7/2017 3:22 PM
Category:Agronomy Series

​There are 16 essential plant nutrients for plant growth. Some of those nutrients are derived from the environment such as Hydrogen, Carbon and Oxygen.  Then there are the macro nutrients which are used in much larger amounts such as Nitrogen, Phosphorus and Potassium.  The micro nutrients, which are used in very small amounts in plant growth and development, are Iron, Manganese, Boron, Chlorine, Copper, Zinc and Molybdenum.  Lastly, there are the secondary nutrients used in moderate amounts, Magnesium, Calcium and Sulfur.  Sulfur is often overlooked because many have adopted the practice of adding Sulfur to the fertility program when fertilizing Cotton. Sulfur deficiency is recognizable by the yellowing of younger leaves while older foliage maintains its deep green color.

Target spot control in cotton with fungicides
on 7/3/2017 11:10 AM
Category:Plant Pathology Series

Target spot is a common and sometimes damaging disease of cotton.  In field trials at the Gulf Coast Research and Extension Center (GCREC), yield losses up to 400 pounds of lint per acre of have recorded on the target spot susceptible variety Phytogen 499 WRF.  The majority of other commercial cotton varieties from Deltapine, Phytogen, and Stoneville/Fibermax have partial disease resistance, thereby making them less prone to significant yield loss than Phytogen 499 WRF as well as fail to respond to fungicide inputs.  Other varieties that have suffered significant but smaller target spot-incited yield losses when compared with Phytogen 499 WRF include Deltapine 1252 B2RF and Fibermax 1944 GLB2.  Factors increasing the risk of damaging target spot outbreaks include excessive nitrogen fertilization and irrigation coupled with frequent July and August showers, while dry and hot weather during this same period will slow and in some cases prevent disease development. Target spot damage is much more likely in cotton grown across the southern third of Alabama and adjacent counties in the Florida Panhandle.  While significant defoliation is sometimes seen in Central AL cotton, yield losses have not been as consistent nor as high as those observed further south, particularly in SW AL.  To date, target spot defoliation in North AL irrigated cotton has been minimal and yield impacts negligible. Fungicides, which delay target spot-incited defoliation, can reduce disease-related yield loss.  The best yield protection with fungicides has been seen in Coastal and South AL in intensively managed cotton.  High risk fields in Central AL but not North AL occasionally benefited from protective fungicide treatments.  Given the relatively slim profit margin for cotton, fungicides are a costly input that should only be considered in high-yield (2.5+ bale/A) potential cotton in high risk settings.  Sizable yield gains from fungicide inputs are unlikely in cotton, particularly outside of SW AL, with a yield potential below 2 bales/A.  The most consistent yield gains have been obtained with Priaxor followed by Headline, Quadris, Twinline, Elatus, and Topguard.  Application rate does not greatly impact the efficacy of any of the above fungicides.
