2001 Corn Herbicide Trial at Hettinger. 

(Eriksmoen) 

Pre-plant incorporated treatments were applied on May 17 and then planted on the same day. Post applied treatments were applied to 4 leaf corn and to 1 to 5 leaf wild oats and to 1 inch to 6 inch field bindweed on June 12 with 57 deg. F, 74% RH, cloudy sky and 6 mph wind. Treatments were applied with a tractor mounted CO2 propelled plot sprayer delivering 17 gpa at 40 psi through 8001 flat fan nozzles to a 5 foot wide by 20 foot long area. The experiment was a randomized complete block design with four replications. The trial sustained severe hail damage on June 18. Evaluations were on July 3 and on July 18 for weed control. The trial was not harvested.
