Andy's Advice:Results Of Intended Herbicide Injury At The Winter Test Site

摘要

Recently seed potato treated with glyphosate and dicamba were sent to the warm climate in Florida at the North Dakota Winter Test for seed potato certification. One of the challenges this year in Florida was too much rain. Because of all the rain there was a poor stand due to seed rotting, similar to what happened in spring 2013 in North Dakota andMinnesota. The purpose of the trip was to evaluate the effect of glyphosate and dicamba in potato seed that was intentionally sprayed. We wanted to determine if dipping seed in gibberellic acid would change theway herbicide-affected seed would respond, evaluate the effects of herbicide injury in the winter test, and help inspectors identify the effects of herbicide residues in seed potatoes.
