The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for APROVIA® TOP Fungicide for control of Alternaria blight (Alternaria panax) on ginseng in Canada. APROVIA® TOP Fungicide was already labeled for management of diseases on a wide range of crops in Canada.
This minor use proposal was 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 APROVIA® TOP Fungicide.
| Crop(s) | Target | Rate (mL product/ha) | Application Information | PHI (days) |
| Ginseng | Alternaria blight (Alternaria panax) | 643 – 967 | Begin applications at emergence and re-apply on a 10-14-day interval when weather is favourable. A minimum spray volume of 200 L/ha is recommended. Increase water volumes as the canopy density increases. Do not apply more than 3.9 L/ha/season. | 14 |
APROVIA® TOP Fungicide contains a new active ingredient for ginseng in FRAC Group 7 – benzovindiflupyr (solatenol) and difenoconazole which is in FRAC Group 3. It is similar in its activity to Miravis Duo, which contains a different Group 7 (pydiflumetofen) and the same Group 3 (difenoconazole) fungicide. While both products should provide effective control, there is more data to show that APROVIA® TOP is effective on Alternaria specifically on ginseng.
APROVIA® TOP Fungicide is toxic to aquatic organisms, certain beneficial insects, and non-target terrestrial plants. Benzovindiflupyr and Difenoconazole are persistent and may carryover. Do not apply this product or allow drift to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers.
Follow all other precautions, restrictions and directions for use on the APROVIA® TOP Fungicide label carefully.
