| IPM Compatibility: |
PER REQUESTER: UNKNOWN IPM FIT; A POSTEMERGENCE HERBICIDE IN A WEED MANAGEMENT PROGRAM WILL CONTROL WEEDS THAT ESCAPE CULTURAL OR MECHANICAL WEED CONTROL OPTIONS; THIS IS A UNIQUE MODE OF ACTION AMONG THE HERBICIDES BEING CONSIDERED FOR HEMP AND HAS VERY FEW RESISTANT WEED SPECIES; EARLY POSTEMERGENCE APPLICATION WHEN THE WEEDS ARE SMALL ALLOWS FOR THE BOOM HEIGHT TO BE LOWERED AND REDUCE THE RISK OF DRIFT:08/19; PER 2019 WSR NOMINATION COMMENT: GOOD IPM FIT; ADDING A CHEMICAL WEED CONTROL OPTION FOR HEMP WILL AID IN OVERALL WEED MANAGEMENT PRACTICES INCLUDING CULTURAL AND MECHANICAL CONTROL; CHEMICAL CONTROL WILL PROVIDE ANOTHER WEED MANAGEMENT TOOL; USE OF MULTIPLE METHODS OF WEED CONTROL IS CONSISTENT WITH GOOD INTEGRATED WEED MANAGEMENT PRACTICES:09/19
|
| Reasons for need: |
BROADLEAF WEEDS; NO POSTEMERGENCE HERBICIDES ARE LABELED IN HEMP; PER MT ME-TOO REQUEST, WEED CONTROL IS THE PRIMARY ISSUE IN HEMP IN MT, AND GROWERS NEED TOOLS FOR DICOT WEEDS
