Abstract

\r\n  Vegetable producers in Arkansas have relatively few options for weed control.  Arkansas' 3,000 acre sweet potato crop is in need of more registered herbicides to address this issue.  A research effort was established to evaluate the effects of Dual Magnum herbicide in a sweet potato weed control program for use in Arkansas.  In conjunction with the Extension Weed Specialist a protocol was developed and trials were established in Lonoke County in a producer’s field. Plot size was 5’ x 20’ and the experimental design was a randomized complete block with four replications.  Plots were sprayed at transplanting utilizing a CO2back pack sprayer and handheld boom. University of Arkansas recommendations for fertility and crop management were utilized in all trials. Control ratings will be taken at standardized timings. Yield data and weed control results were analyzed using ANOVA techiques and means were seperated using Duncan's Multiple Range Test.  Results of this study will be presented to fellow agents and producers.
