Need to renew your pesticide license??? Several categories are offered at our "CEU Variety Pack" on Wednesday, March 27, 2013
Attend the afternoon and core sessions to get your 4 CEUs for renewal for lawn/turf and ornamental categories.
Aquatic, Right-of-way, Natural Areas + others also available.
You can select 2, 4 or 6 CEUs.
To register go to this link: http://ceu-variety-pack-eorg.eventbrite.com/#
AGENDA 9:30-10:00 Check-in
10:00-10:50 Herbicides Modes of Action and Resistance Management
Dr. Bill Haller
Herbicide resistance is a major concern in all herbicide applications. Applicators become comfortable with certain herbicides and herbicide mixes and use them repeatedly year after year. During this presentation, Dr. Haller will give examples of herbicide resistance and how to prevent or best manage to minimize the development of resistant weed populations.
10:50-11:40 Weed Control in Florida’s Waters and Natural Areas
Dr. Lyn Gettys
Dr. Gettys will discuss the common pathways for weed introduction in Florida, present historical accounts of the state’s invasion by hydrilla, waterhyacinth, Brazilian pepper and other weeds and cover management options for controlling the “10 most-wanted list” of Florida’s aquatic, upland and natural areas weeds.
Morning session CEUs: Aquatic (2), ROW (2), NA (2), Demo & Research (2), Private (2),
Comm L & O (1), Lmt. L & O (1), LCLM (1), O & T (1),
11:40-1:00 Turn in survey, receive CEU form and Lunch on own
12:45 – 1:00 Check-in for afternoon session
1:00-1:50 Preventing Herbicide Failures
Dr. Brent Sellers
Dr. Sellers will describe the most common reasons for herbicide failures or reductions in efficacy and how to tailor treatment programs to get the most “bang for your buck” – attaining optimum weed control while minimizing pesticide use and exposure.
1:50-2:40 Equipment Calibration
Dr. Brent Sellers
Dr. Sellers will discuss the importance of equipment calibration and will describe the protocols that should be followed to reduce pesticide use and exposure. This talk will provide valuable information to licensed pesticide applicators of all categories.
Afternoon session CEUs: Aquatic (2), Demo & Research (2), Natural Areas (2), Private (2), Regulatory (2), Right-of-Way (2), Comm. L & O (2), Lmt. L & O (2), LCLM (2), O & T (2)
2:40 turn in survey, receive CEU attendance forms, check-in for CORE
CORE session: 2 CEUs
3:00-4:40 FDACS Vehicle Inspection
Paul Mitola, FDACS Field Training Coordinator
4:40 Turn in survey, receive CEU attendance form, adjourn.
Dr. Bill Haller is a Professor of Agronomy at the University of Florida in Gainesville, specializing in Aquatic Weed Science. His research is focused on aquatic weed management; in addition, Dr. Haller is also the Acting Director of the UF IFAS Center for Aquatic and Invasive Plants.
Dr. Brent Sellers is an Associate Professor of Agronomy at the University of Florida Range Cattle Research and Education Center in Ona, specializing in Weed Science. His focus areas include identifying problematic weeds in pastures and rangeland and implementing economically and environmentally sound control measures, examining weed biology and ecology as related to pasture and rangeland management strategies, and weed control in fence rows and pasture borders.
Dr. Lyn Gettys is an Assistant Professor of Agronomy at the University of Florida Ft. Lauderdale Research and Education Center in Davie, specializing in Aquatic and Wetland Plant Science. Her focus areas include identification, biology and control of invasive aquatic and wetland species, plant propagation and development of novel techniques to increase the success of aquatic restoration and mitigation projects.

If you see some beefy populations (call before they get treated, please). Dr. Eileen Buss' office number is 352-273-3976, and email is firstname.lastname@example.org. No chinch bug will be turned away (unless it's already dead).
She would love to get a couple populations from Georgia, Alabama, and Texas, if possible, too. Have truck, will travel (or pay for FedEx)... :)

Have you been applying iron to turf during the summer N & P fertilizer ban? Do you apply manganese along witht the iron?
There may be a link between applications of iron (Fe) without applications of manganese (Mn) promoting manganese deficiency. The ratio of Fe:Mn should not be less than 2:1. Mn deficiency seems to make the turf more susceptible to take-all root rot.
Please let me know of your experience out in the field. This may change UF recommendations for turf growing on high pH soils, or those irrigated with alkaline water. Post your comment below. Thanks.

These invasive pests are devastating our natural environment and threatening the things we value.
The United States Department of Agriculture is asking for everyone's help to stop the unintended introduction and spread of invasive pests. They urge you to visit www.HungryPests.com to learn more about invasive pests.
Here are a few actions people can take today:
1. Buy firewood where you burn it - transporting wood can spread invasive pests.
2. Plant carefully - buy plants from reputable sources and avoid using invasive plant species. Remove invasive species. See the Florida Exotic Pest Plant Council list of invasive plants: http://www.fleppc.org/list/list.htm
3. Never release aquarium fish and plants into a waterway. Return them to an aquarium shop if possible.
4. Keep it clean - wash outdoor gear and tires between fishing, hunting or camping trips.
5. Learn to identify - if you see signs of an invasive pest, write down or take a picture of what you see and then report it at www.HungryPests.com
6. Only pack and send agricultrally inspected fruits, veggies or plants across state lines.
It is up to all of us to prevent and reduce the spread of invasive species.

Azaleas, magnolias and Indian hawthorn with no spring flowers, shrubs with gaping holes and naked bottoms, trees with multiple trunks or few interior branches are all cause for concern. But before you pull out the pruners, chainsaws and loppers, your plants will be happier if you learn the basics of proper pruning. Here are some things you can do to prune like a professional.
First of all, it’s about timing. Pruning done in the late fall or early winter stimulates new growth, especially if we have a mild winter. This new growth is very tender and is easily damaged, even by a light frost. It is much better to wait until spring bud-break before pruning. This will reduce the risk of cold damage.
Plants that produce their flowers on last year’s growth, such as azaleas, magnolias and Indian hawthorn, must be pruned after they bloom in the spring, and pruning must stop after June when the new buds start to form.
Plants that produce flowers on this year’s growth are usually pruned while still dormant (January/February), or just before the spring growth flush. These plants include hibiscus, allamanda, plumbago, frangipani and rose. To encourage the most plant growth, prune just prior to the first spring growth flush. To slow growth and keep plants smaller, prune just after each growth flush. Most evergreens, such as podocarpus, holly, ligustrum, juniper and wax myrtle, can be pruned anytime.
Secondly, it’s about the cut. There are only two proper cuts. One is called a reduction cut and it removes a larger branch back to a smaller side branch. The second is called a removal cut and it removes a side branch from a larger branch. Flush cuts and topping are harmful and should not be done. When removing branches that are an inch and a half in diameter or larger, use the three-cut method. This keeps the branch from ripping down the side of the trunk. This method starts with a cut on the underside of the branch about 15 inches from the trunk. The second cut is made downward from the top of the branch a few inches out from the first cut. The third cut is the removal of the stub that is left.
