Dear Friends.

I would like to emphasize a topic featured in
this month's Florida Cattleman's Magazine. It is the new Con-
sumer Web Site funded through the Beef Check-Off program. I
am impressed by this site and strongly believe it answers the
questions that an increasing number of Americans are asking:
where, how and by whom is their food produced. This site gives
visitors a virtual view into the daily lives of the nearly 1 million
men and women who make up the U.S. beef industry. The web-
site is easy to navigate and quite comprehensive, including top-
ics on the beef production process, animal welfare, food safety,
nutrition, the environment, government regulations, cooking tips
and recipes. It even describes the choices consumers face when
deciding between grain-fed, grass-finished, certified organic, and
natural/branded beef! I am very impressed with this site and its
creative way to create informed consumers. The web address for
this site is: I highly encour-
age you to check it out!
One more item of importance. For cattlemen and cattle-
women, please be sure to look at the enclosed brochure regard-
ing the 1st Annual Range Cattle Research & Education Center

Extension Tour. This educational program is designed to provide important, timely information to Florida
producers. Dr. Joe Vendramini will discuss current management considerations for Florida pastures; Dr.
Maria Silveira will discuss soil fertility and water quality issues facing Florida cattlemen; Dr. Brent Sellers
will discuss weed management at establishment and for established pastures; and special topics will be
covered by UF Beef Cattle Extension Specialist, Dr. Todd Thrift. The tour is coming to the Hillsborough
County Extension Office Tuesday- April 3rd, 2007. Please refer to the included brochure and register by
March 30th, 2007 to ensure a dinner reservation. We look forward to seeing many of you there. The
greater the turnout, the higher the chance they will choose our county for a tour stop again next year!
Warm Regards,
Steffany L. Dragon oogon ogn

If this plant looks all too familiar and you have found it invading your
pastures recently, you are not alone. It was actually brought in
through Central America; anecdotal evidence suggesting via Mexi-
cans crossing the border...hence the common name. It is a winter i *
annual. Plants show up around October and die off on their own
during the summer. They are known to flower and become most
noticeable March through May. At this time of year, they have al-
ready set next year's seed, so chances are you will see them again.
Since they are annuals, they go to seed quickly in order to secure
the next generation. If killed before
allowing to do so, you will be able to
get them under control. Therefore,
scout for them early this upcoming
fall and as soon as you see them
emerge, zap them with herbicide. 2,4 D or Weedmaster (2,4 D and Dicamba) should
be effective if you get them early enough and before they set the next year's seed.

A few more things to consider:
> Mexican Prickly Poppy is found in disturbed areas and old fields. Proper pasture management, ensuring proper soil
pH and fertilization should allow the desirable species to out-compete them.
> These plants are toxic only if large quantities are eaten. They are not considered to be palatable to livestock & the
'prickly' stems usually deter animals from consuming them.

Teaweed (Sida acuta L.) : A Wildlife Forage

Believe it or not, although Sida (teaweed, ironweed, etc.)
is considered a weed and a detriment to agriculture,
researchers at the University of Florida have found that this
plant can be a benefit to native wildlife...particularly white-
tailed deer, turkeys, and quail. For example, white-tailed
deer require at least 16% protein in the plants they consume
to reach optimum body size and antler growth. Research
shows that even on areas not fertilized, Sida had over 16%
protein. Studies even show that applying 100 pounds of am-
monium nitrate fertilizer raised the crude protein content of
Sida about 3 percent (Williams, R. & Baxley, T.). Over a period of 2 years, browsing amounts
ranged from 193 to over 1,800 Ibs per acre. Deer foraged between 30% and 80% of the available
Sida depending upon the time of year. These are interesting
findings since Sida is not generally listed as a beneficial wildlife for-
age in wildlife management books.

Sida has all the usual characteristics of a weed: drought
resistance, adapability to a wide variety of soil conditions, and the
ability to tolerate heavy browsing by animals. The fact that Sida
can be combined with clovers to create a year long source of forage
for wildlife is perhaps the greatest benefit this plant can provide to
deer, turkey and quail habitat. While Sida seeds are not readily
available for purchase, you will most likely be able to find some
plants on your property or a neighbors'! Hillsborough
county is no stranger to this invasive weed and while
finding a use for it certainly helps make use of what
resources we have available, if you do decide to plant
this plant as a wildlife forage make sure you control it
from spreading to neighboring sites. When in the wrong
place at the wrong time...this plant truly does become a
nuisance and may lead to economic losses to livestock
producers who depend so heavily on healthy pastures.
For more information, please visit the online publication,
"A Native Growing Season Forage for Wildlife-Teaweed,
Sida acuta Burm.f." by Rick Williams & Tim Baxley at: 68.
Additional photos and information can be viewed at the following Web site:


Sida acuta, commonly referred to as teaweed, ironweed, or southern sida, is a woody
shrub that can grow to a height of 3 feet. It is classified as a summer annual but often times
acts as a perennial, persisting throughout the winter months in central and south Florida. It has
small yellow flowers that produce hundreds of seeds throughout the growing season. Sida rap-
idly infests overgrazed areas and usually begins its invasion near troughs, gates, or underneath
shade trees. Then it generally spreads rapidly throughout the pasture. The University of Florida
recommends herbicides with the active ingredients: triclopyr + fluroxypyr (trade name-
PastureGard) or metsulfuron (trade name-Cimarron). Cimarron will kill bahiagrass pastures
and is therefore only recommended for Bermudagrass pastures. PastureGard provides ex-
cellent control of teaweed on bahiagrass pastures and 3 pt/Acre is the recommended rate. Re-
peat applications may be necessary as long as you do not exceed 8 pts/Acre in one season. A
non-ionic surfactant (NIS, sometimes termed a "wetter-spreader") should be added to the spray
mixture at a 0.25% v/v quantity. Let's say for example, that you have a 100-gallon tank. Your
calculation would be .0025 X 100g = .25 gallons (1/4 of a gallon) or 1 quart, since there are 4
quarts in a gallon. Many people make the mistake of calculating 25% instead of 0.25% v/v
which would be incorrectly calculated as 25 gallons of the NIS!
While we are on the subject of non-ionic surfactants (NIS), which brand is best? Dr. Jay
Ferrell, University of Florida Weed Science Specialist admits that he uses them interchangea-
bly and advises that any product with greater than 80% active ingredient will generally be effec-
tive. As a rule of thumb, use 1 qt. per 100 gallons in your tank mix (.25% v/v). Occasionally,
you will see labels for .5% v/v but just be aware that percentages above that are not signifi-
cantly more effective. For example, you will probably see no difference between a .8% v/v NIS
than you will see with a .5% v/v NIS. Dr. Ferrell also recommends steering clear of NISs that
claim equal control at reduced herbicide rates, products that 'reduce regrowth', and cocktails
(spreader+sticker+compatibility, etc.). Remember that products that sound too good to be true
probably are. Oh, and Dawn dishwashing detergent is not a quality NIS!

"Forget organic. Eat local." That's the headline on the cover of the March 12, 2007 issue of
TIME. The cover story's author, John Cloud, says the best food you can eat may be in your own
backyard. The story is billed as "one man's quest for the perfect apple." You can read the full
story at this site:,9171,1595245,00.html
Cloud's six-page feature raises some questions about America's food system that confirms a
growing consumer trend. "What's the most efficient way to grow food?" he asks. "How do our
food choices affect the environment? What tastes better?" The debate Cloud wrestles with (he
lives in an apartment in New York) is whether to buy "organic" apples or "conventionally raised"
local apples. When asked whether a consumer should favor local products, one source told
Cloud, "I don't know what local means. Do they use local pesticides?" Much of the article fo-
cuses on produce, but it also describes a 250-mile diet, which means eating food produced
within 250 miles of where you live. Produce, at least seasonally, can fit such a 250-mile diet for
most Americans. Beef and other proteins, however, are more of a problem. The vast majority of
beef sold at retail and foodservice is transported several hundred miles, which means that a lot
of fossil fuel is burned to get it to your table, and, theoretically, it' bad for the planet. However,
Cloud's article does note that there's plenty of debate about the benefits of organic vs. conven-
tional foods. "'s not clear, for instance, that the low levels of pesticide typically found on con-
ventional produce cause cancer." G.H. Drover's Alert, March 2, 2007

Attention Horse Owners!! "One person's trash is another man's treasure!" We are
setting up a program to help horse owners achieve an economically and environ-
mentally sustainable way to dispose of their mounds of manure while providing
rich soil amendment for gardeners. Aside from making transportation arrange-
ments, manure can usually be exchanged at no cost, since its removal and utili-
zation is desired by each respective party. Please call the Hillsborough County
Extension office at 813-744-5519 ext. 127 to be put on the "Manure Wanted" or
"Manure Available" database. While ma-
nure is in demand, compost is often pre-
ferred, provides benefits to the equine op- OATS
eration (killing weed seed and parasite -
eggs, ETC.), and makes an excellent fertil- '
izer. Composting involves extra work for
the supplier, so most often is associated
with a fee. However, many feel that it is
very well worth it. Please contact me at
the above number for information on how
to compost your manure.
