Herbicide for weed control in corn

MINOR USE LABEL EXPANSION

CALLISTO 480SC HERBICIDE FOR THE LATE POST- EMERGENCE CONTROL/SUPPRESSION OF LABELLED WEEDS ON CORN IN EASTERN CANADA AND BRITISH COLUMBIA

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion for Callisto (mesotrione) for the 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 much 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. The value data to support the registration resulted from work conducted under projects MU03-WEED1 and MU03-WEED2, as part of the PMC’s Minor Use Research 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.

The sponsors wish to thank the personnel of Syngenta Crop Protection Canada, Inc. for their support of this registration.
