The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Posterity fungicide for suppression of Fusarium internal rot on greenhouse pepper and Botrytis grey mould in Canada. Posterity fungicide was already labeled for disease control on a wide range of crops in Canada. These minor use proposals were submitted by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) as a joint project with the United States Department of Agriculture (USDA) IR-4 project as a result of minor use priorities established by growers and extension personnel.
The following is provided as an abbreviated, general outline only. Users should be making disease management decisions within a robust integrated disease management program and should consult the complete label before using Posterity fungicide.
