Missouri Director of Agriculture Chris Chinn on Thursday issued a notice of release from the statewide stop sale, use or removal order for Engenia, XtendiMax with VaporGrip Technology and FeXapan Herbicide Plus VaporGrip Technology. New rules put additional rules and regulations on who can spray the products and the hours of day they can be sprayed. The move follows similar rules announced for use of dicamba products in Tennessee. Arkansas has instituted a ban on in-crop agricultural uses of dicamba products for the remainder of the growing season.The new rules come on the heels of reports of injury in sensitive crops and plants and formal complaints that have been filed with state pesticide regulatory agencies.
