July 28 , 2005 – Each year in mid to late July weeds begin to poke their heads through the soybean canopy, therefore tempting farmers to load up the sprayer for one last trip across the field.
Although they realize much of the impact of the weeds on crop yields may have already occurred, they feel they may still be able to reduce weed seed production and reduce harvest problems. This ariticle summarizes research investigating the impact of late-season applications on weed seed production (Clay, P.A. and J. L. Griffin. 2000. Weed seed production and seedling emergence responses to late-season glyphosate applications. Weed Sci. 48:481-486.).
