Vegetable Weed Science Research Report
AREC-Belle Glade


Preface

The data reported herein is for herbicide evaluation trials
for vegetable crops grown on organic soils. It is hoped that these
data will be of value to all those interested in weed science. These
investigations of herbicide efficacy and vegetable crop tolerance were
conducted in and around the Belle Glade area during the 1981-82 grow-
ing season.

The experiments reported herein were supported by state and federal
appropriations and commercial gifts and grants from the following agencies:

American Cyanamid Company
American Hoechst Company
BASF Wyandotte Corporation
BFC Chemicals, Inc.
Chevron Chemical Company
Ciba-Geigy Corporation
Eli Lilly and Company
Estech
ICI Americans, Inc.
Maag Agrochemical
Mobay Chemical
Monsanto Ag. Products Company
Rohn & Haas Company
South Bay Growers
A. Duda & Sons, Inc.
Hundley Farms
Roth Farms, Inc.

The support of the AREC-Belle Glade Weed Science Program by these
companies is greatly appreciated.

This work would not have been possible without the assistance of
Mr. Gene Wachter, Biologist I, and Mrs. Elsa Garcia, Laboratory
Technician II

The information contained in this report does not constitute a
recommendation or endorsement and is not for publication without consent
