GENERAL INFORMATION
This package contains PRIAXOR DS, a broad-spectrum fungicide. PRIAXOR DS contains two active ingredients, fluxapyroxad and pyraclostrobin, belonging to the carboxamide (SDHI) group of fungicides and strobilurin group of fungicides, respectively.
PRIAXOR DS inhibits spore germination, mycelial growth and sporulation of the fungus on the leaf surface. PRIAXOR DS can be applied in either pre- or post-infection situations. However, optimum disease control is achieved when PRIAXOR DS is applied preventatively in a regularly scheduled spray program and is used in a rotation program with other fungicides.


DIRECTIONS FOR USE (See specific sections for each crop group)
Apply recommended rates of PRIAXOR DS as instructed in the following series of crop application rate tables. Apply PRIAXOR DS with ground or aerial spray equipment as specified. Equipment should be checked frequently for proper calibration.
As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.

Instructions for Aerial Applications
Apply only by fixed-wing or rotary aircraft equipment which has been functionally and operationally calibrated for the atmospheric conditions of the area and the application rates and conditions of this label. Label rates, conditions and precautions are product specific. Read and understand the entire label before opening this product. Apply only at the rate recommended for aerial application on this label. Where no rate for aerial application appears for the specific use, this product cannot be applied by any type of aerial equipment. Ensure uniform application. To avoid streaked, uneven or overlapped application, use appropriate marking devices.

Use Precautions
Apply only when meteorological conditions at the treatment site allow for complete and even crop coverage. Apply only under conditions of good practice specific to aerial application as outlined in the National Aerial Pesticide Application Manual, developed by the Federal/Provincial/Territorial Committee on Pest Management and Pesticides.

Operator Precautions
Do not allow the pilot to mix chemicals to be loaded onto the aircraft. Loading of premixed chemicals with a closed system is permitted. It is desirable that the pilot have communication capabilities at each treatment site at the time of application. The field crew and the mixer/ loaders must wear chemical resistant gloves, coveralls and goggles or face shield during mixing/loading, cleanup and repair. Follow the more stringent label precautions in cases where the operator precautions exceed the generic label recommendations on the existing ground boom label. All personnel on the job site must wash hands and face thoroughly before eating and drinking. Protective clothing, aircraft cockpit and vehicle cabs must be decontaminated regularly.

Product Specific Precautions
Read and understand the entire label before opening this product. If you have questions, call the manufacturer at 1-877-371-BASF (2273) or obtain technical advice from the distributor or your provincial agricultural representative.

ENVIRONMENTAL HAZARDS
TOXIC to aquatic organisms, small mammals and non-target terrestrial plants. Observe buffer zones specified under DIRECTIONS FOR USE.
The use of this chemical may result in contamination of groundwater particularly in areas where soils are permeable (e.g. sandy soil) and/or the depth of the water table is shallow.
Fluxapyroxad is persistant and may carryover. It is recommended that any products containing fluxapyroxad not be used in areas treated with this product during the previous season.


RESISTANCE-MANAGEMENT RECOMMENDATIONS
For resistance management, please note that PRIAXOR DS contains both a Group 7 (fluxapyroxad) and Group 11 (pyraclostrobin) fungicide. Any fungal population may contain individuals naturally resistant to PRIAXOR DS fungicide and other Group 7 and Group 11 fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but are specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay fungicide resistance:
Adhere to the label instructions regarding the use of PRIAXOR DS fungicide or other Group 7 or 11 fungicides as stated in the Crop-Specific Restrictions and Limitations section of the label. DO NOT make sequential applications of PRIAXOR DS before alternating to at least one application of a fungicide with different mode of action other than Group 7 and Group 11.
PRIAXOR DS use should be based on an IPM program that includes scouting, historical information related to pesticide use, crop rotation and considers cultural, biological and other chemical control practices.
Monitor treated fungal populations for resistance development. If disease continues to progress after treatment with this product, do not increase the use rate. Discontinue use of this product, and switch to another fungicide with a different target site of action, if available.
Contact your local extension specialist, or certified crop advisers for any additional pesticide resistance-management and/or IPM recommendations for specific crops and pathogens.
