Fungicide Rotation Tips
• Use the FRAC numbers to your advantage – Products will work better and longer if they are rotated
more often • Back to back applications
– Although they are allowed this is not optimal
• Calibrate your application equipment
– The best products will not make up for poor applications
• Use labeled rates – Cutting rates increase the chances for resistance

Things To Remember About Merivon
• Systemic Properties – Continuous redistribution throughout the plant – Movement is in the Xylem
• Broad Spectrum Disease Control – PM, Botrytis, Anthracnose, Rhizopus
• Post Harvest Disease Control – Protecting the berries in and out of the field.
