| IPM Compatibility: |
PER REQUESTER: VERY GOOD FIT; HERBICIDE OPTIONS IN HOPS FACE RESTRICTIVE MAXIMUM RESIDUE LEVELS IN KEY EXPORT MARKETS LIKE THE EUROPEAN UNION AND HERBICIDE RESISTANCE SPECIES LIKE KOCHIA SCOPARIA. BIOLOGICAL HERBICIDES HAVE THE POTENTIAL TO HELP ADDRESS BOTH OF THESE PROBLEMS BECAUSE OF THEIR FAVORABLE TOXICOLOGY AND NEW MODE-OF-ACTIONS. MBI015 IS AN EXPERIMENTAL BIOLOGICAL HERBICIDE THAT CONTAINS COMPOUNDS PRODUCED DURING FERMENTATION BY BURKHOLDERIA RINOJENSIS STRAIN A396. MBI-015 CONTROL KOCHIA, PRICKLY LETTUCE, AND OTHER BROADLEAVES. HOWEVER, IT DOES NOT CONTROL GRASSES. THE MIXTURES OF MBI-015 WITH TIAFENACIL OR GLUFOSINATE MAY IMPROVE WEED CONTROL EFFICACY WHILE ALLOWING GROWERS TO USE LOWER RATES OF GLUFOSINATE, FOR INSTANCE, TO MEET THE TARGET MRLS FOR EXPORT MARKETS:08/22

| Reasons for need: |
KOCHIA, PRICKLY LETTUCE, AND OTHER ANNUAL BROADLEAVES; NEW MODE OF ACTION AND FAVORABLE ENVIRONMENTAL FATE TO IMPROVE WEED MANAGEMENT OPTIONS
