Drought conditions pose various healthcare and management challenges for horse owners and managers. Conditions associated with drought such as, high temperatures, limited water, and scarce forages, create a harsh environment for horses to thrive in. Fortunately, there are ways to help horses maintain good health despite severe weather. Preparation is key! The following new timely information sheet, " Drought Preparedness for Horse Owners" addresses management strategies and drought preparedness for horse owners in further detail:

The following species of Verbena are present in Alabama, as documented in the Alabama Plant Atlas (Alabama Herbarium Consortium and The University of West Alabama).
Are there many species of Verbena? Approximately 80 species of Verbena or Vervain occur in the world, while most species are found in the South.
Is verbena an annual or perennial? Depending on the species of verbena, they can be annual or perennial. For example, Verbena hastata is a perennial while Verbena officinalis is an annual.
What are distinguishing characteristics of Verbena? They have square, hairy stems and grow to a height of 2-4 feet tall. Most species will have a purple inflorescence on a candelabra-like spike that produces flowers from April to September. The leaves are opposite, simple, lanceolate to ovate-lanceolate; pinnately lobed, dissected or 3-lobed and pubescent.
How does Verbena reproduce? Perennials spread by rhizomes while annuals reproduce by seed.
What areas is it adaptable? Verbena prefers moist soil conditions and partial to full sun. It will grow on roadsides, field borders, wastelands, and pastures.
Is Verbena toxic? There is no information regarding Verbena being toxic to animals.
How do I control Verbena? Verbena may be controlled both mechanically and chemically. Mowing the plants off prior to seedhead formation will reduce stands approximately 75% if the season is dry. Several herbicides are very effective on Verbena if applied when they are less than 5 inches tall including 2,4-D, Weedmaster, Grazon P+D, and GrazonNXT. If the opportunity is missed to spray small, Verbena plants, then mechanically mowing plants before seedhead production will be the best option.

Slobber syndrome ("slobbers"), or slaframine toxicosis, is a chemical irritation and mycotoxicosis resulting from the consumption of Rhizoctonia species-infected legumes, in which excessive salivation is the characteristic sign. However, it is important to note that "Sobbers" may also appear in horses from mechanical irritation, which may be caused by other plants with spines, burrs, or sharp awns on the seeds.

Facet L herbicide: Frequently Asked Questions
Joyce A. Tredaway, Ph.D., Department of Crop, Soil, and Environmental Sciences, Auburn University
March 27, 2017
What hay species can I use Facet L on? Facet L is labeled for most warm-season and cool- season established grasses grown for pasture and hay. The cool-season grasses that Facet L is labeled on are meadow bromegraass, smooth bromegrass, smooth x meadow bromegrass, European dunegrass, fine fescue and tall fescue, Junegrass, Kentucky bluegrass, needle and thread, green needlegrass, orchardgrass, annual ryegrass, Indian ryegrass, perennial ryegrass, bluebunch wheatgrass, bluebunch wheatgrass X quack cross, crested wheatgrass, fairway wheatgrass, fairway X crested wheatgrass, intermediate wheatgrass, pubescent wheatgrass, Siberian wheatgrass, slender wheatgrass, tall wheatgrass, thickspike wheatgrass, Western wheatgrass, Altai wildrye, basin wildrye, beardless wildrye, Dahurian wildrye, mammoth wildrye, and Russian wildrye. The warm season grasses that Facet L is labeled include bermudagrass, big bluestem, little bluestem, sand bluestem, buffalograss, Eastern gammagrass, blue gramma, side-oats gramma, Indiangrass, lovegrass, prairie sandreed, and switchgrass.
What is the recommended application timing? Facet L should be applied early postemergence to small, actively growing weeds and grasses for optimum control. Allow 7 days after application prior to cutting for hay (may graze immediately) so Facet L may translocate through plants effectively to provide control.
What is the recommended rate? Facet L has a application rate range of 22 – 32 fl. oz./acre. However, 32 fl. oz. is the primary use rate necessary for consistent performance on tougher to control labeled broadleaf weeds and grasses.
What about sequential applications? Sequential applications may be used, but no more than 64 fl. oz./acre may applied per year.
Do I need to add anything to Facet L to make it work better? Crop oil concentrate (COC) at 2 pints/acre or 1 to 2 pints/acre of methylated seed oil (MSO) must be added to Facet L for better uptake and enhanced weed control. A nitrogen fertilizer source such as ammonium sulfate (AMS) or urea ammonium nitrate (UAN) can be added for better uptake and enhanced weed control. Facet L may be tank-mixed with other herbicides labeled for use in pasture unless prohibited by the other herbicide label. The most restrictive label applies to tank mixes ie. adjuvant selection. For instance, when Facet L is tank mixed with other herbicides that restrict the use of oil additives, an 80% active nonionic spray surfactant (NIS) at 1 quart per 100 gallons and a nitrogen fertilizer source (AMS or UAN) must be used. However, this may limit the expected performance. Good moisture conditions and actively growing weeds is particularly necessary for Facet L to achieve the best weed control.
Can I use Faced L on newly established hayfields or pastures? NO, Facet L is only labeled for established grass pastures.
Will this injure my forage grass like imazepic containing herbicides such as Plateau, Impose or Panoramic? No, it is very safe on forage grasses in which it is labeled.
What are the grazing/haying restrictions for Facet L? There are 0 days grazing and 7 day haying restriction regardless of rate on Facet L. The reason for this restriction is due to weed control since Facet L is a systemic herbicide which needs to translocate through the weeds to provide complete control.
What weeds does Facet L control? Annual grass weeds controlled postemergence (POST) include barnyardgrass, junglerice, large crabgrass, broadleaf signalgrass, annual foxtails (green, giant, yellow). Knotroot foxtail (Setaria parviflora) is a perennial, warm season grass. Currently, the most recommended herbicide treatments only provide suppression, not complete control and pastures show noticeable stunting and discoloration, particularly
with bermudagrass. Facet L, however, has exhibited significant promise for Knotroot foxtail management in trials over the last several years. Additionally, virtually no pasture response has been observed.
The broadleaf weeds that Facet L controls include clovers, prickly lettuce,morningglory species, hemp sesbania and suppresses common and giant ragweed, Russian thistle, dandelion, sowthistle, and Canada thistle. For best result broadleaf weeds and grasses should be 2 inches or less in height at the time of application.
Does Facet L have residual soil activity? Yes, Facet L provides residual control and can be applied PRE before weeds emerge. However, POST applications to weeds are more effective and consistent.
What does Facet L cost? Retail value of Facet L for 32 fl. oz is approximately $25.00.

Alabama counties have experienced increased levels of drought throughout this past summer and fall. To successfully survive drought conditions, producers must develop a plan that considers not only the present, but also the future. Developing a plan to preserve next year's calf crop is a key part of planning for a successful future. This article will explain the nutritional requirements of beef cows for reproduction and explore management strategies to help preserve next year's calf crop in the current drought situation.
Requirements for Reproductive Success:
Beef cows should be managed to calve at a minimum body condition score (BCS) of 5 to ensure that they have adequate flesh to return to cycling and establish pregnancy. BCS allow producers to estimate the fat stores on their cattle and range from 1 to 9, with 1 being extremely emaciated and 9 being extremely obese. Cows of a BCS 5 will have a good overall appearance, with some fat covering over their spine, ribs, hips, and around their tailhead. As BCS drops below 5, bones become less and less covered by fat and become more visible.
Determining your cows' BCS and managing animals to maintain a BCS ≥5 is essential to ensuring reproductive success. BCS and nutritional status at both calving and during the breeding season affect reproductive success, so it is important to know where your cows are in their production cycle and manage them accordingly. Cows' BCS/nutritional status at calving affects the length of time it takes for them to return to cycling after calving, with cows of low nutritional status at calving taking longer to return to cycling post calving. Once the breeding season is entered, low levels of nutrition and BCS<5 cause reduced pregnancy rates. To survive the drought with next year's calf crop intact, cows must be fed to maintain their BCS.
Cows require different levels of nutrition at different stages of production. Understanding cow nutrient requirements will help producers meet the needs of their cows to maintain a BCS ≥5.
Reference this timely information sheet to learn more about supplementing beef cows on stored hay.
Recognize that your cows' needs are the highest in early lactation. This is the time period when we also need cows to return to cycling and become pregnant. Corners should not be cut during this important time period. Furthermore, note that it's easiest to put weight on cows after weaning. If you currently have thin, dry, pregnant cows it is a good idea to use this time to allow them to gain weight necessary to increase their BCS to 5. As a rule of thumb, you can expect to gain 1 BCS with each 80 lbs of weight gain in mature beef cows.
Pregnancy examination is essential in all years, but is extremely important this winter as we continue or recover from drought. If cows have not been examined for pregnancy, consider having a veterinarian palpate your cows and cull open cows that have weaning age calves. This will allow for added income and less mouths to feed through the winter and early spring. As you complete this year's breeding season, pregnancy check your cows. Since resources were limited, there is a chance that BCS dropped too low and more cows than usual may be open at the end of the breeding season. It is essential to identify and cull these individuals.
Additional Strategies in Times of Extreme Drought:
By taking care to manage cattle to nutritional levels necessary for pregnancy success, a producer can preserve next year's calf crop through drought situations.
As Alabama continues to experience drought conditions across the state, many cattle producers are thinking about how they can economically feed cattle through the winter months. With limited rainfall, forage production potential is low, which means most producers will rely on stored forage and supplement to meet the nutritional needs of the herd. Initial hay reserves left over from the 2015 season have now been exhausted, and most are feeding this year's crop. Limited rainfall over the spring and summer months in 2016 reduced the number of hay harvests this year. In the best cases, some producers averaged three to four cuttings. However, those in areas of extreme drought may have only been able to harvest one or two cuttings at best. Strategies for managing the nutritional needs for cattle now are going to be based off of these supplies and require some forward thinking into projected conditions for spring 2017.
Three Things Producers Can Do Today
Three Things Producers Must Consider Now for Later
As Alabama continues with below average rainfall and above average temperatures, the drought is taking its toll on the pastures and hayfields. In drought situations, animals will eat plants that they normally probably wouldn't because of the lack of forage availability. This leads to many animals eating toxic plants that are normally not eaten by them, although they have always been present in the field. Toxic plants may be found in fields, in shade areas, or on fence lines, and although not normally palatable, animals eat them for survival. Unfortunately, toxic plants contain nitrates, cyanide, tannins, and certain alkaloids and glycoalkaolids that when eaten, can cause neurological, physiological, and even death.
Some common toxic plants that are present in Alabama include perilla mint, jimsonweed, pigweed, ragweed, pine trees (tannin in the needles), nightshades, groundcherry, johnsongrass, goldenrod, Canada thistle, corn, wheat, oats, sudangrass, sorghum-sudangrass, brackenfern, mountain laurel, oaks, poison hemlock, pokeweed, crotalaria, and wild cherry. This is only a partial list of the toxic plants that are present in Alabama but are very common.
The age-old question of "why are my forages dying but my weeds are healthy and surviving?" is becoming more and more prevalent as the drought continues. Weeds, unlike improved forages, have the ability to adapt to droughty conditions. They have the ability to keep water inside and maintain it, close off their stomates so that no water escapes, grow longer roots to find water, and even change their leaves so that they will keep more water. Unfortunately, improved plants that have been bred for different characteristics don't have this innate ability. Therefore, that is why your forages are dying while your weeds are still alive.
The question is how do I control these weeds in a drought? Since stomates must be open for a plant to "take in" a herbicide, and in a drought, stomates are closed, herbicide applications for these plants are not advised. Until there are several rains and the drought is lifted is only when a herbicide application would be advised. The only practice that is recommended is to mow selectively the toxic plants (not the forage), making sure to get all of the seed head, which is often the most toxic. If the high temperatures continue, a frost will be delayed however, if normal temperatures start to occur, a frost can help to kill your toxic plants and aid in the control of some of them. However, a frost can also cause nitrate levels to increase in plants, which may cause more toxicity to occur.
It would be nice if we could be done with fall armyworms for the year. But they will be around until the first hard frost. Please keep looking for fall armyworms in your forage crops. On the bright side, as the weather cools down it will take longer for the armyworms to complete a generation.
I am especially concerned about small grains that are planted early for forage, wildlife, or cover crops, such as wheat, oats, and rye. These small grains should be scouted from emergence through the first hard frost. These newly planted grains should be scouted frequently, at least once a week, by visually examining the plants. A sweep net can be used as a first detection tool in overseeded areas where the perennial grass is still green. The sweep net is not useful in row crop areas until the wheat gets about 4 inches tall. On the smaller plants, look for signs of something feeding on the plants. Also look for the small caterpillars under any crop debris in the field. They tend to hide during the day. Scouting early in the morning or late in the increases the chances of seeing the caterpillars on the foliage. Pay close attention to any bare spots in the field, which could be a sign that something isdefoliating the seedling grain.
A reasonable threshold to use in fall planted small grains is 1 caterpillar per square foot. This is adjusted downward from the 2-3 per square foot threshold we use for established grass forages.
Insecticides are available to control the fall armyworms on wheat and other small grains. However, they are not all the same as those used on grass forages. So here is the link to the small grain IPM Guide:
Small Grain IPM Guide - IPM-0458. The insecticides recommended for use for fall armyworms are listed in Table 5 starting on page 7. Only one trade name for each active ingredient is listed in Table 5. So you may need to check Table 6, which starts on page 12. This table contains a list of most of the generic insecticides. Some insecticides labeled on small grains are not labeled for perennial grass pastures and hayfields. So in situations where the small grain has been overseeded into perennial grass sod,be sure to pickan insecticide thatis alsolabelled for perennial grass forages (see 2016 Insect and Weed Control Recommendations - IPM-0028). Remember, it is not legal to apply an insecticide to a site unless that site is listed on the label.
As with our summer forages, choosing an insecticide with a longer residual will provide more protection from fall armyworms. The insecticides labeled on small grains that have the longest residual for fall armyworm control are Prevathon (active ingredient chlorantraniliprole) and Besiege (active ingredients chlorantraniliprole and lambda-cyhalothrin).
Early planted small grains are also subject to infestation by Hessian fly and by aphids that spread Barley yellow dwarf and cereal yellow dwarf virus. I did a webinar yesterday that discusses management strategies for these problems, as well as for fall armyworm.
