Products used for Disease Control for Suppression on Grapes

Use this table as a guide but refer to product label for specific information.

The preharvest interval (PHI) is the number of days between the last spray and first harvest.

The restricted entry interval (REI) is the minimum interval that must be observed between the application of the pesticide and work in the treated crop without protective equipment. When the REI for hand harvest exceeds the PHI, follow the REI.

The maximum applications is the labelled maximum number or product amount applied for the growing season and may be higher than what is recommended for resistance management.

Preharvest Intervals: Contact processors and wineries directly regarding their preharvest interval policy. Preharvest intervals listed are taken from product labels. In some cases, regulations on residues in finished products are much more stringent. Many processors require longer preharvest intervals than stated on product labels. Some processors and wineries also have special restrictions for certain pest control products regarding number of applications or application after a certain crop stage. Consult your grape purchaser for more details.

Products listed as potentially organic may be acceptable for organic use based on MAPAQ. Réseau d’avertissements phytosanitaires. 2022. RAP – Réseau Général. Bulletin d’information N° 1, Spécial phytoprotection bio. 14 juillet 2022, or a letter of certification provided by the registrant. Check with certifying body to verify the acceptability of any product prior to using it.

M = Multi-site fungicides. BM = Biologicals with multiple modes of action. NC = Not classified by FRAC, or group not indicated on product label. P = Plant defence inducers. UN = Mode of action has not been determined. — = Information is not specified on the product label. * = Potentially organic. Check with certifying body.

Contact = stays on surface of plant. Locally systemic = Moves into plant but does not move to other plant parts. Systemic = Moves into plant and to unsprayed plant parts as they develop. SAR = systemic acquired resistance: Moves into plant and activates resistance genes.
