Insect Biocontrol Agent for Waterbyacinth

A new insect that will help control the invasive weed waterhyacinth
has been released by Aqzricultural Research Service (ARS) scientists
and cooperators.

Waterhyacinth is a free-floating aquatic plant native to South
America that is no stranger to citrus growers. Dense populations of
waterhyacinth can affect water quality, infrastructure for pumping,
water use and biodiversity. Other problems include fish kills due to
low oxygen levels and increases in populations of vectors of human
and animal diseases.


M. scutellaris is a small planthopper native to South America whose
nymphs and adults feed on the sap of waterhyacinth. Nymphs are
active and readily hop, even off the surface of the water. The
insect's population increases rapidly, which will enable it to quickly
impact the waterhyacinth population.

Herbicides are the primary method for reducing waterhyacinth, but
their use directly interferes with the biocontrol agents currently
deployed against this weed. The scientists believe M. scutellaris may
integrate better with existing herbicide programs because of its
mobility, which should improve its survival in such highly managed

Citrus Black Spot Monogement Timing Schedule
Dr. Megan Dewdney, CREC, Lake Alfred has authored a new CBS
Management Timing Schedule, Plant Pathology document PP 277.
The front side of this document details recommended fungicides
and application timing to control CBS. The back side of the
document is entitled Foliar Fungal Management Program and charts
out the recommended application timing windows for all the
common citrus fungal diseases. Handy laminated versions of this
document will be available at various citrus programs and at my
office in the near future.

Medfly Found in Palm Beach County
The first major outbreak of the Mediterranean Fruit Fly in Florida since
1998 has occurred in Boca Raton in the southeast portion of Palm
Beach County. FDACS inspectors have subsequently trapped a

number of wild flies in mango, loquat and sour orange trees in the
immediate area of the initial find.
According to an FDACS news release, "the Mediterranean fruit fly
(Medfly) is considered the most serious of the world's fruit fly pests
due to its potential economic harm and threat to our food supply. It
attacks more than 250 different fruits, vegetables and nuts, including
oranges, grapefruit, lemons, apples, guava, mango, tomatoes and
peppers. The flies' eggs are laid in the fruit and develop into
maggots causing the fruit to rot. They then emerge as adults once
the fruit falls to the ground. Medflies breed continuously when host
fruits are available. Population growth may be explosive, as females
are capable of producing hundreds of eggs".

Additional trapping operations and spot sprays on host trees in the
area are being conducted at this time. For more information on this
potentially serious pest, click on the following link:

New FAWN Site for Indian River County
Due to the efforts of the Indian River Citrus League and a number of
growers, it appears that we will have a new FAWN (Florida
Automated Weather Network) site west of vero Beach on 122nd Ave.
The Ft. Pierce FAWN site at the IRREC is generally 2 -5 degrees
warmer than the agricultural areas to the west and this new site will
give us much more representative live and saved data during cold
weather events. The site is not up and running at this time but should
be available by the time winter rolls around.

2010 Citrus Expo
Preregistration is now open for the 2010 Citrus Expo to be held on
August 18 & 19, 2010 at the Lee Civic Center in Ft. Myers. Growers
who register online (saves time standing in line for a badge at the
show and helps plan for numbers for lunch) will be eligible in a
drawing for a great big John Deere gun safe. The Citrus Expo
registration page has postings for the participating host hotels and
also information on a new Casino Night Fundraiser for FFA. Could be
a fun night for a great cause!

It appears that the planning committee has scheduled an applied
lineup of presentations for the Citrus Expo Seminar, with more time for
each speaker to hone in on their subject. Click on the following link
to preregister for the program, review the program and find lots of
other useful information:

2011 International Research Conference on HLB
Another research conference on HLB has been scheduled for
January 10-14, 201 1 in Orlando. Similar to the conference held
almost 2 years ago, many researchers, regulatory agency
representatives and commercial industry leaders from around the
world will gather to present the latest information, knowledge,
concepts and ideas related to HLB. Click on the following link to
access the conference website:

Stone Fruit and Blueberry Workshop Presentations
We had about 60 interested participants at this workshop which was
held on June 15, 2010 at the IRREC. The presentations by IFAS
Extension Specialists Drs. Mercy Olmstead and Jeff Williamson and
additional stone fruit and blueberry information are located at the
following web address:

Just for Fun
Nugene skipped work at the sawmill one day and took his son fishing.
While they were out in their boat, the boy suddenly became curious
about the world around him. He asked his father, "Dad, how does this
boat float?"

The father replied, "Don't rightly know son."

A little later, the boy looked at his father and asked, "Dad, how do fish
breath underwater?"

Once again the father replied, "Don't rightly know son."

A little later the boy asked his father, "Dad, why is the sky blue?"

Again, the father replied, "Don't rightly know son."

Finally, the boy asked his father, "Dad, do you mind my asking you all of
these questions?"

To which Nugene replied, "Of course not, son. If you don't ask questions,
you'll never learn nothing. "

Virgil headed down to the creek as he did every morning to draw a
bucket of water so his mom could wash the breakfast dishes. Five minutes
later, he came running back as if he'd seen a ghost, with the empty
bucket in his hand.

""What's the matter, Virgil?" asked his mother.
"I'd just waded out into the creek to get a nice, clean bucket of water, "
he gasped, "when I looked up and saw a six foot alligator just layin' there
looking' at me."
"Ah shoot," said his mother, "a gator that size is probably more afraid of
you than you are of it."
"If that's true," said Virgil, "there's no point in me going back, a'cause
that water ain't fit for washin'!"
