"Field trials were conducted from 2005 to 2007 at two locations in southwestern Ontario to investigate how weed control in corn was affected by the time of day that herbicides were applied. Weed control following the application of six POST herbicides (atrazine, bromoxynil, dicamba/diflufenzopyr, glyphosate, glufosinate, and nicosulfuron) at 06:00, 09:00, 12:00, 15:00, 18:00, 21:00, and 24:00 h was assessed," scientists in Harrow, Canada report.
"For many weed species herbicide efficacy was reduced when applications were made at 06:00, 2 1:00, and 24:00 h. Velvetleaf was the most sensitive to the time of day effect, followed by common ragweed, common ...
