A Message From the President

Fellow Growers,

Well, we have weathered through summer and fall is upon us. Buds are setting, final fertilizer applications
are being made, as well as final fungicide sprays. I hope you have been blessed with just the right amount
of rain that kept you from having to irrigate as much as we have during the past couple of summers.

Fall is also the time for our biennial blueberry growers meeting. This year the meeting will be held in Bartow
at the Polk County Agricultural Center in the Stuart Center. We will be hearing a terrific line up of topics.
There will be a silent auction as well as raffle tickets available for purchase to raise money for blueberry
research. So come prepared to support "the cause" and maybe walk away with some really nice prizes.

See you there,
Jerry Mixon, Jr
Mixon Family Farm and FBGA President




Fire Ant Test

By Paul Lyrene, Horticultural Sciences, Dept., University of Florida, Gainesville, Fla.

This test is based on the book: Fire Ants, Stephen Welton Taber. 2000. Texas A&M University Press, College
Station, TX. Order from: http://www.tamu.edulupress/BOOKS/2000/taber.htm

This is a great book accurate, complete, and fun to read, with numerous useful and interesting
illustrations. The answers to the test can be found on pages 3 4. Any mistakes are probably mine and not
that of Stephen Welton Taber. Test your fire ant IQ by marking the following true or false.

1. There is only one species of fire ant.

2. Fire ants can raise the pH of the soil while increasing phosphorous and decreasing organic matter.

3. Fire ants can kill citrus trees by girdling the bark.

4. Most of the damage done by fire ants to soybeans, corn, and okra is due to feeding on the roots.

5. Grits sprinkled on the ground will cause fire ants eating them to explode.

6. The Argentine fire ant which was introduced through the port of Mobile in 1918 has nearly been
eradicated from the U.S.


7. Fire ants feed primarily on liquids.






8. Fire ant mating is extremely hard to observe in nature.


9. Fire ant queens live less than one year.

10. There are two forms of social organization in fire ants a form with only one functional queen per colony
and a form which sometimes has tens of thousands of egg-laying queens per colony functioning
simultaneously.

11. Multiple-queen colonies are more resistant to Amdro than monogyne colonies.

12. A single polygyne colony can bud into eight in less than half a year.

13. Amdro, a popular fire ant bait, contains a fluorinated hydrocarbon mixed with grits and soybean oil.

14. A substance present in okra flowers is so attractive to fire ant foragers that it is being studied for
possible use in fire ant baits.

15. Amdro is more effective than Mirex, which was banned in the U.S. in 1978.

16. Fenoxycarb (Logic) sterilizes fire ant queens.

17. When using a drench against a fire ant nest, you should sneak up on the mound without causing the
ground to vibrate with heavy footfalls.

18. Phorid flies, introduced from Brazil to control fire ants, can decrease ant foraging by 80%, even if they
kill only a few ants.

19. In citrus, fire ants pack soil into the wounds they make on the stems where they feed, and can thereby
introduce fungal pathogens into the plant.

20. Fire ants are known to feed on blueberry roots.

21. Fire ants can befriend the blueberry farmer by feeding on root weevils and other potentially serious
insect pests.




Meet Steve Blount: Our Featured Blueberry Grower

I began planning my blueberry farm in 1989. I went to various other farms to get ideas on the best planting
practices to incorporate into the initial planting of my farm which would prevent high maintenance
requirements down the road. I received valuable input in the initial planting concerning drainage and plant
spacing as well as plant varieties from Dr. Paul Lyrene from the University of Florida, and Dick Kearley and
Tim Logan from the blueberry farm known as Florida Blueberries, Inc.

I cleared the land which is a loamy type soil and bedded the various rows in order to get additional
drainage. I then laid a plastic mat ground mulch for weed control which I had found to be one of the biggest
problems in the various fields I had observed.

I had purchased some plants and maintained them under a sprinkler system in the first block of my field. A
friend told me about a blueberry farm which had closed down and pulled all the plants up out of the pine
bark mulch rows and stacked them under a makeshift sprinkler system. I made a deal with the farm owner
and potted the approximately 11,000 plants and transported and planted them on my farm.

Although I have dealt with the same natural occurrences that other farmers have dealt with, my farm
continued to be profitable with a minimum amount of maintenance. My advice to someone contemplating
planting a blueberry farm is to start off with a small planting and try different varieties to see which
reforms best on your soil and in your area. Also, be prepared to weather the various natural occurrences
which you will certainly have to deal with.








Comparison of Methods for Detecting Blueberry Gall Midge in 2002


By Dr. Oscar Liburd and Erin Finn, Entomology and Nematology, University of Florida

Blueberry gall midge, Dasineura oxycoccana Johnson, is an important insect pest that feeds on floral and
vegetative buds of blueberry bushes. Female midges lay their eggs when bud scales start to separate
during the spring. Eggs hatch into larvae (maggots) within a few days, and the emerging maggots feed on
plant juices within the buds. Symptoms of infestation include premature floral bud abortion, leaf curl,
stunted growth, and blackened leaf tips. In response to grower concerns, entomologists in the Small Fruit
and Vegetable laboratory at the University of Florida focused their attention on ways to provide early
detection of blueberry gall midge within blueberry plantings. During 2002, various colors of sticky
monitoring boards were evaluated because of their wide use in similar agricultural programs for monitoring
insect pests. Preliminary results indicate that sticky boards were ineffective in providing early detection of
gall midge adults. Several reasons prevented sticky boards from being practical for use in blueberry
plantings. First, gall midges were difficult to distinguish from other insects on the boards. Secondly, the
sticky glue on the board surface often disturbs characteristic antennal segments and fine hairs on the
wings of midges that are useful in making a positive identification. Two other methods for detecting
blueberry gall midge as possible alternatives to using colored sticky boards including larval-adult
emergence and bud dissection techniques were evaluated. Emergence and dissection methods performed
equally well for detecting larvae (maggots) in the buds. However, the dissection method was the only
technique capable of detecting blueberry gall midge eggs and it appears to be more reliable when gall
midge populations were low.




Answers to Fire Ant Test

1. There are many. Our worst is the red imported fire ant, native in central and western Brazil. When it
arrived at the port of Mobile sometime between 1933 and 1945, it began to rapidly out-compete and replace
the black Argentine fire ant, which had been introduced into Mobile in 1918. There are also the wide-spread
tropical fire ant, 3 fire ants native in the U.S., and at least 12 species still in South America that have not
made it to the U.S.

2. Yes, at least in Louisiana pasture land.

3. True.

4. True.

5. False.

6. True, but not by us. The red Brazilian fire ant, introduced later, has driven the Argentine black fire ant to
the extreme northern limits of where it can survive, near Memphis, Tennessee.

7. True. They suck the juices out of insects and plant material.

8. True. Just before mating, the sexual ants begin leaving the nest at rates up to 100 per minute. They mate
on the wing, at altitudes of about 1,000 feet. Probably only 1 in a thousand mated queens survives to found
a successful nest.

9. False, fire ant queens can live up to 7 years.

10. True.

11. True.


12.True.





13. True.

14. True.

15. False. Mirex was more effective. Widely used in the U.S. from 1965 to 1978, its registration was canceled
because it was highly persistent in the environment and there was evidence that it could cause liver
damage in mice. By contrast, Amdro is considered less toxic to mammals, it degrades rapidly, it is only
slightly soluble in water, and it has a 95% kill rate.

16. True.

17. True. If the workers hear you coming, they will move the queen to safety deeper down in the nest.

18. True. The ants stop moving when phorids are in the area.

19. True.

20. True. This was reported in 1993 in J. Entomol. Sci. 28:236-39 for rabbiteye blueberries.

21. True. Fire ants consume large numbers of insects of many kinds. They do, however, make scale insects
worse on blueberries by farming them.
