July 14, 2009 – The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion for Callisto (mesotrione) herbicide.
The label expansion covers late post-emergence control/suppression of labeled weeds on seed and sweet corn in Eastern Canada and British Columbia.
Callisto 480SC herbicide is a suspension concentrate (SC) that provides selective control of annual broadleaf weeds in corn. It is a new mode of action for post emergence broadleaved weed control that has shown to be very effective in field corn. The herbicide is already registered in Eastern Canada (PCP # 27833) for pre-emergence use in field, seed, and sweet corn, and post emergence use in field corn for control of annual broadleaf weeds namely, lamb’s-quarters, redroot pigweed velvetleaf, wild mustard and common ragweed (suppression).
This label expansion will provide corn growers with a needed post-emergence weed management tool for seed corn and sweet corn. This minor use submission was compiled by the Agriculture and Agri-Food Canada, Pest Management Centre (AAFC-PMC) Minor Use Pesticide Program.
This label expansion, achieved through the User Requested Minor Use Label Expansion (URMULE) process of PMRA, was sponsored by AAFC-PMC in response to minor use priorities established by corn producers, processors, extension personnel and researchers in Canada.
