Final Project Results

Updated March 25, 2019:
The survey results and information on our current Palmer amaranth and waterhemp distribution and abundance were included in presentations made available to OSU Extension educators for use in pesticide applicator and other training. This information was also presented by Mark Loux, extension weed specialist, to Ohio growers and agribusiness at several other meetings in November and December. We also conducted hands on training of OSU Extension educators on identification of pigweed species at a December inservice training. - Mark Loux and Bruce Ackley developed a folder of information that is being provided by OSU Extension educators to clientele at pesticide recertification and local agronomy meetings this winter. We made 8000 folders available for distribution. New fact sheets developed for this purpose – stewardship of dicamba in Xtend soybeans and a completely revised marestail control fact sheet. guide to identification of Ohio pigweed species, and a fact sheet that summarizes the nature of the palmer amaranth problem, with an emphasis on guidelines for prevention of new infestations. The folders also included updated fact sheets on management of LibertyLink soybeans and Palmer amaranth in Ohio overview, an updated herbicide site of action chart, an amaranth identification fact sheet, and a USB Take Action fact sheet on waterhemp control in soybeans. - Seeds of Amaranthus spp. collected during the fall 2017 survey of soybean fields, or submitted by clientele, were cleaned and placed in cold room. The cold conditions promote germination when these seeds are planted later in winter for screens to determine herbicide resistance.
