If anything positive can be taken from this scenario it is the fact that producers have time to scout their READ FULL ARTICLE Ryegrass Management: Scout Now for Fall Control Donnie Miller and Daniel Stephenson LSU AgCenter Each year producers in Louisiana fight a constant battle against weed species bent on robbing yields and shrinking profit margins. Due to the widespread adaptation of the Roundup Ready technology and subsequent overuse of only glyphosate for weed management, confirmation of weed resistance to glyphosate takes READ FULL ARTICLE The battle within the battle: Glyphosate Resistant Palmer amaranth BY: Dr. Daniel Stephenson, Weed Scientist, LSU AgCenter The recent cool, wet weather can influence herbicide application decisions for weed management in corn. Numerous acres of corn in Louisiana were damaged by frost this past weekend and a majority of that corn ranges V3 to V5 (3 to 5 visible collars).
