The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of New World screwworm (Cochliomyia hominivorax) in a stray dog near Homestead, Florida. The dog was isolated and his infested wounds were treated. Federal and state officials have started active surveillance in the area.

This is the first confirmed case on Florida’s mainland. Screwworm was first confirmed on October 3, 2016 in Key deer from National Key Deer Refuge on Big Pine Key, Florida. This initial presence of screwworm was the first local detection in the United States in more than 30 years and Florida’s Commissioner of Agriculture, Adam Putnam declared an agricultural state of emergency in Monroe County, Florida.

Since October, 13 Keys had known infestations mostly in the key deer population, with five confirmed infestations in domestic animals. Animal health and wildlife officials at the state and federal levels have been working aggressively to eradicate this pest. Extensive response efforts have included fly assessments to determine the extent of the infestation, release of sterile flies to prevent reproduction and disease surveillance to look for additional cases in animals. Officials have received significantly fewer reports of adult screwworm flies in the area and fewer cases of infected Key deer. To date, fly assessments have been conducted on 40 Keys. USDA has released over 80 million sterile flies from 25 ground release sites on twelve islands and the city of Marathon. The initial epidemiology report on the Florida Keys infestation may be viewed at https://www.aphis.usda.gov/stakeholders/downloads/2017/nws-epi-report.pdf.

Life cycle of New World Screwworm from Fernandez and White, 2010. Investigation into Introduction of New World Screwworm into Florida Keys

Residents who have warm-blooded animals (pets, livestock, etc.) should watch their animals carefully. Florida residents should report any potential cases to 1-800-HELP-FLA (1-800-435-7352) or non-Florida residents should call (850) 410-3800.  Visitors to the area should ensure any pets that are with them are also checked, in order to prevent the spread of this infestation.

While human cases of New World screwworm are rare, they have occurred, and public health officials are involved in the response. No human cases have been reported in Florida. For more information about this disease in humans, please contact your local public health department. Using fly repellents and keeping skin wounds clean and protected from flies can help prevent infection with screwworm in both people and animals.

New World screwworm are fly larvae (maggots) that can infest livestock and other warm-blooded animals, including people. They most often enter an animal through an open wound and feed on the animal’s living flesh. While they can fly much farther under ideal conditions, adult flies generally do not travel more than a couple of miles if there are suitable host animals in the area. New World screwworm is more likely to spread long distances when infested animals move to new areas and carry the pest there.

In the 1950s, USDA developed a new method to help eradicate screwworm using a form of biological control, called the sterile insect technique, which releases infertile flies in infested areas. When they mate with wild females, no offspring result. With fewer fertile mates available in each succeeding generation, the fly, in essence, breeds itself out of existence.  USDA used this technique to eradicate screwworm from the U.S. and worked with other countries in Central America and the Caribbean to eradicate it there as well. Today, USDA and its partners maintain a permanent sterile fly barrier at the Darien Gap between Panama and Colombia to prevent the establishment of any screwworm flies that enter from South America.

There are over 1000 springs identified in Florida. In the Panhandle, the majority of the springs are karst or artesian springs rising deep from the Floridan Aquafer System within the states limestone base.  Springs are unique and can be identified by perennial flows, constant water temperature and chemistry, high light transparency.  This yields a freshwater ecology dependent on these features.  Springs are classified based upon the average discharge of water but can exhibit a lot of variability based on water withdrawals and rainfall. These springs are some of our most precious water resources, supplying the drinking water our communities rely on, as well as providing great recreation opportunities.

Morrison Springs is a popular spring in northwest Florida and is one of 13 springs flowing into the Choctawhatchee River Basin. It is a large, sandy-bottomed spring surrounded by old growth cypress.  The spring pool is 250 feet in diameter, discharges an average of 48 million gallons of water each day from three vents into the Choctawhatchee River as a second magnitude spring.  The spring contains an extensive underwater cave system with three cavities up to 300 feet deep and is popular for scuba diving, swimming and snorkeling, kayaking, canoeing and fishing.  Historically, it was privately owned and was a popular swimming hole for locals.  In 2004, the state of Florida purchased the land containing the spring in the Choctawhatchee River floodplain.  The land was leased to Walton County for 99 years.  The county created a 161-acre park with a picnic pavilion, restroom facilities and a wheelchair-accessible boardwalk.  A down-stream boat ramp provides access to the river away from swimmers and divers.  There is no entrance fee.

Morrison Spring is filled with abundant fish and plant life. Fish include largemouth bass, spotted bass, hybrid striped bass, bluegill, sunfish, redbreast sunfish, warmouth, black crappie, striped bass, catfish, alligator gar, bowfin, carp, mullet and flounder or hogchoakers (freshwater sole).  It is also home to some nocturnal freshwater eels that swim around the vent and delight the divers. Most are gray, about an inch in diameter and maybe a foot or two long.  The spring supports many trees, plants, and grasses including bald cypress, live oak, red maple, pawpaw, red and black titi, Cherokee bean, sweetbay, blackgum, juniper, red cedar, southern magnolia, laurel oak, tupelo, hickory, willow, wax myrtle, cabbage palm, saw palmetto blueberry, hydrangea, St. John’s wort, mountain laurel, water lily, pickerelweed, pitcher plant, broad leaved arrowhead, fern, and moss.

Morrison Springs was previously considered one of the cleanest springs in Florida until 2010 (Florida Springs Initiative). All of Florida springs are currently at risk as the state population continues to increase.  Spring flows are decreasing as the result of increasing extraction of groundwater for human uses.  Development, and the resultant over pumping, and nitrogen pollution from agriculture both have impacts on the aquifer recharge areas.  Existing groundwater pumping rates from the Floridan Aquifer in 2010 were more than 30% of average aquifer recharge (Florida Spring Initiative).  The University of Florida IFAS Extension Agents in the Panhandle occasionally conduct interpretive guided tours of the Springs to help citizens understand the importance of protecting this unique water source.

Bay County Deploys First Super Reefs in Panama City Beach

Bay County Deploys First Super Reefs in Panama City Beach

Super Reef Deployment Location Graphic

Earlier this year, Bay County completed an artificial reef project in Gulf waters approximately 3 nautical miles (nm) south of the Panama City Beach Pier (Pier Park) and 11 nm west of St Andrew Bay Pass in Small Area Artificial Reef Site D. On May 14, five Super Reefs were deployed, each weighing approximately 36,000 lbs and rising 18 feet from the ocean floor. Typical artificial reef modules are only about 8 feet tall. This was the first time Super Reefs were deployed in western Bay County in the Panama City Beach area. The project provides marine habitat comparable to sinking a large vessel.

Mexico Beach Artificial Reef Association (MBARA) supported Bay County and Walter Maine during the deployment efforts. MBARA provided this YouTube video documenting the deployment and post-deployment dive survey. During the survey, divers noted baitfish already utilizing the new habitat. The Super Reef module coordinates and details were verified as follows:

 

Patch Reef # Latitude Longitude Depth (ft) Permit Area
BC2015 Set 17 (1) 30° 10.196N 85° 54.607 W 74 SAARS D
BC2015 Set 18 (2) 30° 10.179 N 85° 54.567 W 75 SAARS D
BC2015 Set 19 (3) 30° 10.176 N 85° 54.603 W 75 SAARS D
BC2015 Set 20 (4) 30° 10.153N 85° 54.594 W 73 SAARS D
BC2015 Set 21 (5) 30° 10.138 N 85° 54.602 W 73 SAARS D

Previous monitoring and research suggest it takes 3 to 5 years for new reefs to reach full development of the associated marine ecosystem. Bay County will work with local anglers, divers, reef associations, and agencies to evaluate the performance of the new reef materials and the reef design.

Bay County artificial reef projects seek to use material that meets program goals and objectives. In this case, larger reef materials were selected to support larger reef fish such as amberjack, grouper, and snapper. Individual reef modules were spaced to support fish forage areas and accommodate multiple users including anglers and divers.

Funding for this $ 60,000 project was provided by Florida Fish and Wildlife Commission’s Artificial Reef Program. Additional reef projects were deployed by the Mexico Beach Artificial Reef Association earlier in the week. The Bay County Artificial Association (BCARA) is also planning new reef deployments in Bay County. Learn more about Bay County’s public artificial reefs at http://x.co/reefm.

Ergot: A Fungal Disease in Argentine Bahiagrass Found in Jackson County

Several calls have come in to the Jackson County Extension Office recently from producers regarding something unusual in their “Argentine” bahiagrass fields.  A parasitic fungal disease called ergot (Claviceps paspali) is growing on the seedheads (racemes) of Argentine bahiagrass, in fields that have been allowed to reach maturity for seed production or delayed hay harvest.  The weather conditions lately have certainly been favorable for fungal disease:  cloudy days, high humidity, and frequent rainfall.  If you have Argentine bahiagrass pastures, you should be familiar with the symptoms of this fungal disease, so you can monitor it and manage accordingly.  There are two major concerns with ergot:  1) ergot spores contain a toxin that affects livestock and 2) ergot decreases seed production. The fungus actually prevents flower fertilization and seed formation, so the main issue for seed producers is just a mild to serious loss in overall yield.  Ergot toxicity from bahiagrass is very rare, but could become an issue under the right conditions.

Ergot Identification

Argentine bahiagrass is much more commonly infected with ergot than the “Pensacola” cultivars (Tifton-9, TifQuik, UF Riata).  The “Pensacola” cultivars on the other hand are more susceptible to dollar spot (Sclerotinia homoeocarpa), which is a fungal disease of the leaf tissue.  Ergot spores are spread by wind, insects, or animal movement.  The fungus first infects the bahiagrass flowers and then grows in place of the seed.

Ergot frequently infects grasses in the genus Paspalum (bahiagrass) in the southern United States. The infection cycle begins with sexual spores (ascospores) spread by wind or possibly insects. The fungus infects the pistil of the flower at the time of flowering by colonizing the styles of susceptible plants, and a few days later the content of the ovary is replaced by fungal tissue.  The sign of ergot infection appears at flowering (anthesis) when a sugar-rich honeydew (exudate) is produced on infected flowers (florets). The honeydew makes seed heads feel sticky, and the exudates contain the asexual spores (conidia) that are responsible for initiating secondary infections (Fig. 1 A and B). Disease development is correlated to environmental conditions of high humidity, cloudy days, and warm temperatures, after which the disease cycle ends by forming a mass of dark fungal tissue (sclerotium) that replaces the seed and forces the glumes apart (Fig. 1 C and D). Additionally, ergot-infected seed contains alkaloids that are poisonous to animals.  Ergot Resistant Tetraploid Bahiagrass and Fungicide Effects on Seed Yield and Quality

Toxicity

Ergot toxicity is not a common issue with grazing livestock, but is something worth monitoring in Argentine bahiagrass fields, at this time of year.  The fungus only affects the seedheads, so the rest of the plant is nontoxic.  With normal, rotational or continuous grazing, the percentage of mature seedheads in a given pasture is fairly limited.  The greatest concern is turning livestock in to graze a pasture with a high percentage of mature seedheads in mid to late summer.  This might be an issue in a field where seed production or hay production was abandoned and instead utilized for grazing. Or perhaps a pasture that has not been utilized for several weeks, that has become more mature than normal in a rotational grazing system.

The key to livestock poisoning is the amount of toxic spores that are consumed.  The old adage, “The solution to pollution is dilution” is certainly true with livestock. The key is to avoid long, continuous exposure, or feeding toxins in a high percentage of the diet.

Intake of ergot bodies should be <0.1% of the total diet, and concentrations of ergot alkaloids should be <100 ppm in the total diet. Ergotism can be controlled by an immediate change to an ergot-free diet.  Merck Vet Manual

The NRCS Bahiagrass fact sheet contains the following statement:

Caution: Seed heads of the cultivar ‘Argentine’ are often infected by ergot (Claviceps paspali). Pregnant mares can experience abortion problems, if they eat large quantities of infected seed heads. Also, ingestion of infected seeds can produce toxic effects in cattle. USDA NRCS – Plant Materials Center

There are different forms of ergot, depending on the crop, season and location.  According to Ergot as a Plant Disease, the form of ergot (Claviceps paspali) found in bahiagrass and dallisgrass affects the nervous system. The common name for animals affected is “Bahiagrass Staggers” or “Dallisgrass Staggers.”  The ergot that occurs in cool-seson forages or crops such as rye or wheat, and ryegrass (Claviceps purpurea) causes lameness, hoof and tail decay, and even gangrene.  Ergot toxicity can also affect milk production and abortions in pregnant animals.

Animals consume ergot by eating the spores (sclerotia) present in contaminated feed. All domestic animals are susceptible, including birds. Cattle seem to be the most susceptible. The responses of animals consuming ergot are usually quite variable and are dependent on variations in alkaloid content, frequency of ingesting ergot, quantity of ergot ingested, climatic conditions under which ergot grew, the species of ergot involved, and the influence of other impurities in the feed such as histamine and acetylcholine.  Two well-known forms of ergotism exist in animals, an acute form characterized by convulsions, and a chronic form characterized by gangrene. A third form of ergotism is characterized by hyperthermia (increased body temperature) in cattle, and a fourth form is characterized by agalactia (no milk) and lack of mammary gland development, prolonged gestations, and early foal deaths in mares fed heavily contaminated feed. Which form of ergotism is manifested depends on the type of ergot consumed and the ratio of major toxic alkaloids present in the ergot: ergotamine, ergotoxine,and ergometrine. Claviceps purpurea, the common cause of ergot in North Dakota, is usually associated with gangrenous ergotism. Claviceps paspali, an ergot of Paspalum species of plants (bahiagrass & dallisgrass), is most commonly associated with central nervous derangement.  The responses of animals consuming ergot are usually quite variable and are dependent on variations in alkaloid content, frequency of ingesting ergot, quantity of ergot ingested, climatic conditions under which ergot grew, the species of ergot involved, and the influence of other impurities in the feed such as histamine and acetylcholine.  Ergot as a Plant Disease

Symptoms of Bahiagrass Staggers

The same ergot fungus (Claviceps paspali) that affects Argentine bahiagrass also effects dallisgrass, that is more common in other parts of the South.  The following is a description of the symptoms of egrot toxicity from the same fungus that also affects Argentine Bahiagrass.

Clinical signs of Dallisgrass Staggers involve the animal’s nervous system. In the very early stages of the disease, the only sign seen may be trembling of various muscles after exercise. As the disease progresses, muscle tremors worsen so that the animal becomes uncoordinated and may show continuous shaking of the limbs and nodding of the head. When forced to move, this severely affected animal may stagger, walk sideways, and display a “goose-stepping” gait. Incoordination can be severe enough that the animal will fall down when attempting to walk. Some animals may be found down and unable to stand. Diarrhea may also be noted in some affected animals. Death can occur in severe cases, especially in scenarios where cattle are naïve to grazing dallisgrass. There is no cure for ergot poisoning, but removing cows from infected pastures when symptoms are first noticed usually results in uneventful recovery in three to five days. Mowing seedheads to prevent animals from grazing them helps prevent the problem from occurring. Ergot toxicity from dallisgrass hay is very uncommon since the total intake of hay forage dilutes any ergot contained in the hay. Ergot Poisoning and Dallisgrass Staggers

Management of Ergot in Bahia

The intent of this article was not to scare livestock producers, but simply to make them aware of a potentially serious issue. Before turning cattle or other livestock into an Argentine bahiagrass pasture with mature seedheads, it is a good idea to scout the field for the severity of this disease. Once a serious level, >20% of the pasture becomes infected, it would be better to be cautious, mow the seedheads off and wait a few weeks before grazing.  Pregnant animals, particularity mares should be moved to an alternate location, and even stalled if need be, until the severity of the infection in a pasture is reduced. Once the fungal materials are mowed off and the seedheads decay, there is always potential for reinfection, based on the right environmental conditions returning (heavy, continuous rainfall, humidity and mature seedheads).
Most of the cases of livestock fatalities and abortions involved contaminated feeds or bedding straw that were consumed on a regular basis, at fairly high levels.  Ergot toxicity from livestock grazing bahiagrass is not a common occurrence, but conditions at this point in the summer are ideal for the development of this disease, so it is something to keep an eye on.  If you do have animals grazing Argentine bahiagrass, and they seem to be acting strange, have muscle tremors, lack coordination, or are disoriented, the first course of action would be to move livestock to a new pasture immediately to change their diet,  monitor their behavior, and advise your veterinarian of the situation.  If conditions don’t rapidly improve, consult with your veterinarian.  There are other diseases that can cause similar symptoms that may require very different treatment.

Corn Harvest Underway in Jackson County

The combine was running hard harvesting field corn this week near Greenwood, FL at Bishop Farms.

This combine was running hard harvesting field corn this week near Greenwood, FL at Bishop Farms.

Harvest is always an exciting time on the farm.  Months of work, investment, and risk pay off when the crop comes in.  This week several farms in Jackson County started harvesting field corn from both dryland and irrigated fields. Reported yields for dryland fields ranged from 90-130 bushels per acre.  Irrigated corn yields ranged from 200-280 bushels per acre.  It appears that yields will be off a little this year, slightly below average, due to the several weeks of hot dry weather at the end of June and early July.

Ethan Carter, Regional Crop IMP Agent, measured corn to calculate corn yields at Bishop Farms.

Ethan Carter, Regional Crop IMP Agent, measured corn to calculate corn yields at Bishop Farms.

Ethan Carter, Crop IMP Regional Agent, did some yield checks at Bishop Farms at a cornfield near Greenwood, Florida.  Dekalb 6659 was the variety that provided excellent yields in this field.

The National Corn Growers Association offers a national corn yield contest.  For this contest, yields have to be evaluated by an unbiased third party such as your County Extension Agriculture Agent.  The deadline for entry this year was today, July 29, 2016.

Even if you missed the entry deadline for the national contest, doing some spot yield checks is just good information to have.  Typically, yield checks are more accurate than the yield monitors provided in combines.  Having accurate yield records for different varieties can help determine the best varieties to plant in the future.  It also provides valuable information about management decisions made from year to year.  If you would like assistance doing spot yield checks of your field corn, contact your local county extension office.

The following are some highlights from Bishop Farms harvest this past week.  Not only are the harvest equipment running non-stop, but they are also prepping the land and planting a second crop of soybeans right behind the combine.  The first is a short video of the combine in action, and some photos of the process follow.

The Deepwater Horizon (DWH) oil spill occurred about 50 miles offshore of Louisiana in April 2010. Approximately 172 million gallons of oil entered the Gulf of Mexico. Five years after the incident, locals and tourists still have questions. The Okaloosa County UF/IFAS Extension Office invited a Gulf of Mexico Oil Spill Scientist, Dr. Monica Wilson, to help answer the five most common questions about the oil spill and to increase the use of oil spill science by people whose livelihoods depend on a healthy Gulf.

The event was held at the Destin History and Fishing Museum on Monday evening, July 11, 2016. Executive Director, Kathy Marler Blue partnered with the University of Florida to host the event. “The Destin History and Fishing Museum has a vision that includes expanding its programs to include a lecture series,” said Blue. Over 20 interested individuals attended the lecture and the question and answer session was lively. This was the first in what hopes to be an ongoing lecture series, bringing more scientific information to our county.

Dr. Wilson is based in St. Petersburg, Florida with the Florida Sea Grant College Program. Monica uses her physical oceanography background to model circulation and flushing of coastal systems in the region and the impacts of tropical storms on these systems. She focuses on the distribution, dispersion and dilution of petroleum under the action of physical ocean processes and storms. For this lecture, she covered topics such as: the safety of eating Gulf seafood, impacts to wildlife, what cleanup techniques were used, how they were implemented, where the oil went, where is it now, and do dispersants make it unsafe to swim in the water?

The oil spill science outreach program also allows Sea Grant specialists to find out what types of information target audiences want and develop tailor-made products for those audiences. The outreach specialists produce a variety of materials, such as fact sheets and bulletins, focused on meeting stakeholder information needs. The specialists also gather input from target audiences through workshops and work with researchers to share oil spill research results at science seminars that are facilitated by the specialists.

The Destin History and Fishing Museum is a nonprofit organization whose members are dedicated to preserving, documenting, and sharing the complete history of Destin. Please subscribe to their Facebook page for information on upcoming events. The UF IFAS Extension Okaloosa County office also hosts a Facebook page with announcement of upcoming programs.

Spotted Wilt Virus showing up in Jackson County Peanuts

Spotted Wilt Virus showing up in Jackson County Peanuts

Figure 1. Peanut plants stunted by tomato spotted wilt virus in 2016. Pictures were taken on June 10th of peanuts which were planted in late April

Always unpredictable, spotted wilt disease of peanut in the southeast has ebbed and flowed over the years.  For many years, the disease was moderate to severe at the North Florida Research and Education Center near Mariana, Florida.  Then in 2010, the incidence decreased dramatically with only the most susceptible lines showing a few symptomatic plants even under conditions which favor disease development.  While it is unclear what 2016 holds for spotted wilt pressure, it is clear that thrips pressure has been extreme this spring and for the first time in years, we are observing diseased and stunted plants early in the season- by late May to early June.

Diseased plants such as those above in Figure 1 will remain stunted throughout the season and will produce few, if any, peanuts.  Early stunting from spotted wilt is the most devastating symptom of spotted wilt in terms of yield loss, especially if incidence is high.  So far, the incidence is relatively low (less than 10%) in the research plots at NFREC, Marianna, but the season is young and that could change quickly.  Figure 2 below shows a close-up view of the spots on leaves of peanut which are characteristic of spotted wilt disease.

Unfortunately, there are no in-season control measures for spotted wilt.  Everything that can be done to reduce the risk of spotted wilt is done before, or at the time of planting.  Major factors to consider are variety choice, date of planting, seeding density, and in-furrow insecticide.  Fortunately, most of today’s cultivars have better resistance than Georgia Green which should reduce the risk of severe losses.  Similarly, we plant a majority of the peanut crop in the southeast during the latter half of May, which reduces risk.  Achieving a uniform and quick plant stand of at least four plants per foot of row is important to reduce risk.

In the past, there were two common in-furrow insecticides to control thrips- Temik® and Thimet®, but Temik has been withdrawn from the market.  Choices for in-furrow insecticides are becoming more numerous and include CruiserMaxx® seed treatment, Admire® Pro liquid (or Imidacloprid generics) in-furrow, and Thimet® granular in-furrow.  Of these three, only Thimet® has been shown to control thrips AND reduce the risk of spotted wilt.

Spotted wilt may or may not be problematic in 2016, but it is still good for growers to scout their fields so they know how much spotted wilt is out there.  Just because we have been in a lull for the past several years is no reason to think that the disease can’t occur.  It is important to maintain vigilance against spotted wilt and do everything you can to reduce the risk of disease.
