Abstract
Studies determined the effect of common lambsquarters, goosegrass, and a mixture of these on ‘Beauregard’ and ‘Jewel’ sweetpotato transplant production with or without polyethylene bed covers. Effects of herbicides on Beauregard in propagation beds were also studied. Black and infrared transmissible (IRT) plastic covers gave near 100% control of goosegrass and common lambsquarters, resulting in the greatest number and weight of Jewel transplants per plot. Common lambsquarters reduced transplant number and weight per plot with Jewel under clear plastic covers when compared with black and IRT plastic covers. Beauregard transplant number was not affected by row cover treatment. However, with data combined over all covers, Beauregard transplant weight per plot was lowest for treatments with weeds compared to weed-free plots. With the exception of DCPA, no significant (10% or greater) injury to Beauregard was observed with diphenamid, napropamide, chloramben, or chloramben plus fluazifop.
