CHEMICAL WEED CONTROL METHODS FOR GROWER TRIAL


 IN VEGETABLE CROPS ON ORGANIC SOILS OF

 THE EVERGLADES

 (Supersedes EES Mimeo Report 57-6)

 J. R. Orsenigo


 Chemical methods of weed control are gaining popularity as production tools
in vegetable crops. Alone, these chemicals do not insure a record crop; but,
the herbicidal treatments listed below offer timely, effective, and economical
weed control for certain vegetables. As with any practice, the best results are
obtained by using: THE RIGHT CHEMICAL FOR THE CROP AND WEEDS: IN THE RIGHT
AMOUNT: IN THE RIGHT WAY: AT THE RIGHT TIME: and IN THE RIGHT PLACE.

 The recommendations and suggestions in this report are intended for grower
guidance and familiarization with herbicides, application methods, and the
potential of weed control chemicals under each grower's situation. It is
suggested that initial trials be restricted to limited acreage and that the
precautions and indications of the manufacturer's label be carefully followed.

 Herbicide rates are expressed on a per-covered-acre basis in terms of
active ingredient. A brief glossary of herbicides and herbicide terminology
is given on page 3 and is followed by illustrations of methods of herbicide
application.

RECOMMENDED herbicidal treatments (chemical, rate, and manner of application)
are those considered generally reliable for commercial production when used as
specified. It is recommended that growers without prior herbicide use experience
confine their initial applications to a limited acreage.

SUGGESTED herbicidal treatments may represent promising materials which have not
been fully tested locally or materials which do not have current FDA approval
for the crops indicated. Growers may wish to utilize suggested treatments on
a trial basis on a very limited acreage.

 GREEN BEANS: PRE EMERGENCE

RECOMMENDED: DINITRO, 9 to 12 lbs./A. (Rate should be cut to
 3 Ibs./A. if beans are breaking ground)

SUGGESTED: EPTAM 4 to 6 lbs./A.
 RA.DOX 4 to 6 lbs./A.
 VEGEDX 4 to 6 lbs./A.

 CABBAGE: DIRECT-SEEDED: PRE-EMERGENCE

RECOMMENDED: RANDOX 4 to 6 lbs./A. (more effective on grasses)
 VEGEDEX 4 to 6 lbs./A. (more effective against broadleaf
 weeds)
