The Pest Management Regulatory Agency (PMRA) recently approved two minor use label expansion registrations for Flint fungicide for suppression of powdery mildew on edible honeysuckle (haskaps), and suppression of botrytis leaf blight and purple blotch on bulb vegetables (CG 3-07 A & B) in Canada. Flint 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 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 Flint fungicide.

Rate (g of product / ha) |
Application Information |
PHI (days) |
Edible Honeysuckle (Haskap) |
Suppression of Powdery Mildew |

Begin applications preventatively and continue on 7-14 day interval. Use the higher rate and shorter application interval when conditions favour development of severe disease pressure. Use sufficient water to obtain thorough coverage (min 300L/ha). DO NOT exceed 3 total applications of FLINT Fungicide per season. |

Bulb Vegetables (CG 3-07 A & B) |
Suppression of Botrytis Leaf Blight and Purple Blotch |
