New Federal Label for Engenia, FeXapan, and XtendiMax
on 10/20/2017 11:58 AM
Category:Agronomy Series; Weed Science Series

The EPA approved revised labels for Engenia, FeXapan, and XtendiMax on Friday, October 13th.  They have aligned the labels to coincide with each other which will make it much easier. The biggest change is that now these products are Restricted Use Products (RUP).  This means that only certified applicators, or those under their guidance, will be allowed  to purchase and apply these products. Record keeping is required of all applications. The label will list the full requirements but applicators have 14 days to generate the records and the records must be kept for at least two years. The rainfree requirement is 24 hours between application and either a rainfall or irrigation.  Only daytime applications, between sunrise and sunset, are permitted. Applications are not permitted when the conditions exists for a temperature inversion. The sprayer must be cleaned both before and after application. Cleanout procedures must be documented as part of the RUP (date and method, as a minimum).  Maximum travel speed is 15 mph with a recommendation of 5 mph on field borders. All supplemental labels are now combined into the main label. The use of an approved buffering agent may be warrented if the water source or tank mix components will create an acidic spray solution less than a pH of 5.  In addition, sensitive crop awareness as part of the RUP by documenting that the applicator, at a minimum, surveyed neighboring fields or consulted a sensitive crops registry.

Since Alabama had a 24c last year, some of the same regulations will apply in the new label that were implemented in our 24c label last year. These include that applicators must complete an auxin-specific training, wind speed may not exceed 10 mph with the range being 3-10 mph, and not applying the herbicide when the wind is blowing in the direction of sensitive crops or downwind of the crop.

Alabama may make restrictions in addition to the main federal label. Decisions on this will be made soon and information will be forthcoming.

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.
