Preparing for the Fall/Winter blueberry season

Dormex. Growers should decide soon whether or not they will use Dormex, and if so, how much they will need. A review
of current Dormex research in Florida, and information on placing Dormex orders, will be provided at the Fall Short Course. If
you are not able to attend the Blueberry Short Course, you can contact Mr. Rick Hill by phone at (813) 781-0902 to place
your order. A discussion of use of Dormex on Florida blueberries can be found at: http://www.hos.ufl.edu/jgwweb/
Click on "past issues". Look at the Winter 2001 issue. There are a few updates that should be noted since that article
was written. The Dormex label now calls for rates of 1.5% to 3.0% (v/v). However, our research has shown that rates of
3.0% or greater have resulted in substantial flower bud injury and reduction of crop load. In one recent experiment, a rate of
2.5% (v/v) caused considerable flower bud damage in a potted study, but not in a grower's field trial. Care should be
exercised when applying rates higher than 2.0%. Further discussion of rate responses can be found in the Winter 2001 issue
of Blueberry News Several cultivars such as 'Sharpblue', 'Windsor' and 'Primadonna' have shown greater than average
sensitivity to Dormex resulting in significant flower bud damage. Emerald, Jewel and Star have generally responded well to
Dormex in north-central Florida but many other newer cultivars have not been thoroughly tested. The following statement
was taken from the Dormex label "It is the grower's responsibility to identify varieties that are tolerant to the higher
rates before any larger acreage is treated. To do this, take a small group of plants to be treated at the appropriate rates under
the anticipated growing conditions and observe for phytotoxicity symptoms before treating large numbers of plants".
Our research and observations in Florida have also indicated that thorough coverage is very important for a good
Dormex response. Spray volumes of 50 to 100 gpa are called for by the label and are usually required for good coverage in
typical Florida blueberry fields. Remember that Dormex is a restricted-use pesticide with many specific requirements
for handling and application. Growers without a certified pesticide applicators license, or without the proper equipment
for handling and application, should consider having Dormex custom applied by a certified applicator.
Freeze protection. Virtually all early-season blueberry fields in Florida are subject to late winter or early spring freezes.
This year's Fall Short Course will feature a detailed presentation on freeze protection by Dr. Dorota Haman. Even before
the short course, there are a few things growers can begin to think about with regards to winterizing their blueberry fields.
I have reproduced a useful list of activities below that was taken from an article by Mike Mainland in the North
Carolina Blueberry News, Vol. 7, No. 1.
Reinstall suction lines and check primers.
Test and service the pumping unit, replace filters and have spare filters available.
Treat diesel tanks for water and algae.
Check lines and sprinklers in the field for leaks and clogged nozzles.
Check water pressure on ends of distant lines.
Make sure drainage in and around fields is adequate. Make sure roadways around and through the fields will withstand
traffic at night during irrigation.
Have a high-intensity spotlight ready to plug into the truck to check sprinkler operation
Make sure drainage in and around fields is adequate.
Put shielded minimum thermometers in cold, average, and warm areas of fields.
Hang some ribbons on trees or poles around fields to detect slight breezes.
Identify a good source of agricultural weather information and watch it closely. Consider subscribing to a weather service
that issues freeze warnings.
Consider purchasing a monitor that calls you when the temperature gets low.
Consider purchasing a hand-held wind meter or anemometer to measure wind speed.
Consider purchasing a sling psychrometer to measure wet bulb and dry bulb temperatures, relative humidity, and dew
point. An excellent discussion of these terms and their importance in cold protection can be found at http://edis.ifas.ufl.edu/
Have rain suits and boots available for everyone responsible for checking the irrigation system.
Have wires available to unclog nozzles.
Have tools and replacement parts that are necessary to exchange nozzles and/or sprinklers.
