Gentlemen:

This is the time for the Branch Experiment Stations and the Main Station to
begin preparing for their Vegetable Field Days.

Here are the dates and times of the ones that have been set:

Plantation Field Laboratory, Ft. Lauderdale, Florida
Thursday, April 16, 1959 at 1:30 P.M.


Indian River Field Laboratory, Ft. Pierce, Florida
Wednesday, April 29, 1959, at 1:30 P.M.


Everglades Experiment Station, Belle Glade, Florida
Thursday, May 7, 1959, at 9:00 A.M.


Central Florida Experiment Station, Sanford, Florida
Thursday, May 14, 1959, at 1:30 P.M.
Zellwood Friday, May 15, 1959, at 9:00 A.M.


Gulf Coast Experiment Station, Bradenton, Florida
Probably the first or second week in May but will be confirmed later


Main Station, Gainesville, Florida
First week in June but will be confirmed later


There are several things that need to be brought out in vegetable production
and we would like to pass them on for your information.

First, we have had numerous requests for information on the effectiveness of
insecticides mixed in fertilizer on sweet potatoes for control of sweet potato
weevils. It is not effective on the weevil. The weevil itself is not a soil
insect. They lay eggs on the soil in the vicinity of the sweet potato roots and
the larvae hatch and migrate through the soil cracks made by the sweet potato
roots as they grow. The only effective control is by applying the insecticide
to cover all of the soil surface around the plants. Complete instructions for
both plant bed and field treatment are found in Extension Circular 152, Extension
Circular 97B or Extension Circular 160.






Here is another one which we have already "cooled off", if not, would you
please explain it to your pepper and tomato growers? We have no field research
evidence that powdered milk will control viruses. There has been a lot of
powdered milk used by pepper growers in south Florida this spring. We are of
the strong opinion at this time that they are wasting their money. This use
of sprays with powdered milk was influenced by a research report appearing in
the Plant Disease Reporter issued by the USDA for February 15, 1959. The
research was sound and the results look promising; however, it was a laboratory -
greenhouse experiment and has not been tried in the field. The only virus used
was tobacco mosaic. We do not know how effective milk is on the other viruses
which are more of a problem than TMV on peppers and tomatoes in Florida. Do not
advise the use of milk on these crops. If and when it is proven to be effective
and economical we will advise you.

Another approach to control of these viruses on peppers is being worked on
in Florida. The plant breeders at the Agricultural Experiment Station now have
pepper breeding lines which are resistant to potato Y virus, tobacco mosaic virus
and etch virus. It shouldn't be too long before we will have varieties available
which are resistant to these viruses.
