Reduced Risk Status:
IPM Compatibility: PER REQUESTOR VERY GOOD FIT, LOW HUMAN TOXICITY COMPARE TO PARAQUAT; SHORT-TERM SOIL LONGEVITY MAY ELIMINATE CONTAMINATION IN HOP CONES THROUGH THE SOIL DUST LIKE IS LIKELY OBSERVED IN PARAQUAT; RESISTANCE MANAGEMENT IN THE WESTERN USA AS GROUP 14 CASES ARE NOT YET PRESENT AND IN OREGON MANAGEMENT OF GLUFOSINATE-RESISTANT RYEGRASS;
Reasons for need: CANADA THISTLE, ITALIAN RYEGRASS, KOCHIA OTHER ANNUAL DICOTS, AND MONOCOTS; POTENTIAL REPLACEMENT FOR PARAQUAT IN HOPS ACTIVITIES IN GRASSES WILL IMPROVE WEED CONTROL COMPARED TO CARFENTRAZONE
