RESISTANCE MANAGEMENT
For resistance management, please note that Metconazole 50 WDG Fungicide contains a Group 3 fungicide. Any fungal population may contain individuals naturally resistant to Metconazole 50 WDG Fungicide and other group 3 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 specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed. To delay fungicide resistance: Where possible, rotate the use of Metconazole 50 WDG Fungicide or other group 3 fungicides with different groups that control the same pathogens. Avoid application of more than the maximum number listed in the label and consecutive sprays of Metconazole 50 WDG Fungicide or other fungicides in the same group in a season. Use tank mixtures with fungicides from a different group when such use is permitted. Fungicide use should be based on an IPM program that includes scouting, historical information related to pesticide use and crop rotation and considers host plant resistance, impact of environmental conditions on disease development, disease thresholds, as well as cultural, biological and other control practices. Where possible, make use of predictive disease models to effectively time fungicide applications. Monitor treated fungal populations for resistance development. Notify Valent Canada Inc. if reduced sensitivity of the pathogen to Metconazole 50 WDG Fungicide is suspected. 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 advisor for any additional pesticide resistance-management and/or IPM recommendations for specific crops or pathogens. 

GENERAL INFORMATION

MODE OF ACTION
The active ingredient in Metconazole 50 WDG Fungicide is metconazole, a broadspectrum triazole fungicide that works by inhibiting demethylation and other processes in sterol biosynthesis. Metconazole 50 WDG Fungicide is systemic and is quickly absorbed into plant tissue. Metconazole is absorbed quickly into the plant tissue and can move up, but not down, in the plant. Metconazole has no effect on fungal spore germination, but interferes with other early developmental processes in the life cycle of certain fungi. Although Metconazole 50 WDG Fungicide cannot prevent spore germination, it prevents spore formation and inhibits mycelial growth. Metconazole 50 WDGFungicide is most effective when applied prior to infection. Optimal disease control is achieved when Metconazole 50 WDG Fungicide is applied in a regularly scheduled spray program and used in combination and/or rotation with other effective fungicides that have different modes of action (i.e., non-Group 3 fungicides). Metconazole 50 WDG Fungicide is a sterol biosynthesis inhibitor; avoid rotating with other sterol biosynthesis inhibitors.

RAINFASTNESS
Applications should not be made if rain is expected within 2 hours of application or disease control may be reduced.

SPRAYER PREPARATION
Before applying Metconazole 50 WDG Fungicide, start with clean, well maintained application equipment. The spray tank hoses and booms must be cleaned to ensure no residue from the previous spraying operations remain in the sprayer. The spray equipment must be cleaned according to the manufacturer's directions for the last product used before the equipment is used to apply Metconazole 50 WDG Fungicide. If two or more products were tank mixed prior to Metconazole 50 WDG Fungicide application, the most restrictive cleanup procedure should be followed. Application equipment should be clean and in good repair. Nozzles should be frequently checked for accuracy.

SPRAYER CLEANUP
Clean sprayer equipment each day following Metconazole 50 WDG Fungicide application. After application is complete, use the following steps to clean spray equipment:
1. Completely drain the spray tank, rinse the sprayer thoroughly, including the inside and outside of the tank and all in-line screens.
2. Fill the spray tank with clean water and flush all hoses, booms, screens, and nozzles.
3. Drain tank completely.
4. Remove all nozzles and screens and rinse them in clean water.

MIXING INSTRUCTIONS
1. Fill clean spray tank 1/2 to 2/3 of desired level with clean water.
2. While agitating, slowly add the Metconazole 50 WDG Fungicide to the spray tank. Agitation should create a rippling or rolling action on the water surface.
3. If tank mixing Metconazole 50 WDG Fungicide with other labeled pesticides, add water soluble packets first, followed by dry formulations, flowables, emulsifiable concentrates and then solutions.
4. Add any required adjuvants.
5. Fill spray tank to desired level with water. Agitation should continue until all spray solution has been applied.
6. Mix only the amount of spray solution that can be applied the day of mixing. Apply Metconazole 50 WDG Fungicide within 24 hours of mixing.

SPRAY VOLUME
Apply Metconazole 50 WDG Fungicide in sufficient water to ensure thorough coverage of foliage, blossoms, and fruit. Thorough coverage is required for optimal disease control. For ground application, apply a minimum of 200 L of spray mixture per hectare. For aerial application, apply a minimum of 50 L of spray mixture per hectare to ensure uniform coverage.

AERIAL APPLICATION
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. Do not apply to any body of water. Avoid drifting of spray onto any body of water or other non-target areas. Specified buffer zones should be observed. Coarse sprays are less likely to drift, therefore, avoid combinations of pressure and nozzle type that will result in fine particles (mist). Do not apply during periods of dead calm or when wind velocity and direction pose a risk of spray drift. Do not spray when the wind is blowing towards a nearby sensitive crop, garden, terrestrial habitat (such as shelter-belt) or aquatic habitat.
Product Specific Precautions
Read and understand the entire label before opening this product. If you have questions, call the manufacturer at (519) 767-9262 or obtain technical advice from the distributor or your provincial agricultural representative. To minimize drift, apply the largest droplet size consistent with uniform coverage and satisfactory disease control. To obtain satisfactory application and avoid drift, the following directions must be observed:
Do not apply during low-level inversion conditions, when winds are gusty or under other conditions that favour drift. Do not spray when wind velocity is less than 3 km/h or more than 16 km/h.
Carrier Volume and Spray Pressure:
Application at less than 50 litres per hectare may provide inadequate coverage and control. The higher litreage applications generally afford more consistent disease control. Do not exceed the nozzle manufacturer’s recommended pressures. For many nozzle types, lower pressure produces larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
Nozzle Selection and Orientation:
Formation of very small drops may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much as possible and by avoiding excessive spray pressure. Use nozzles that produce flat fan or cone spray patterns. Use non-drip type nozzles, such as diaphragm type nozzles, to avoid unwanted discharge of spray solution. The nozzles must be directed toward the rear of the aircraft, producing a spray discharge at an angle between 0 and 15° downward. Do not place nozzles on the outer 25% of the wings or rotors.
Adjuvants and Drift Control Additives:
Refer to tank mix partner’s label for adjuvant recommendation. Drift control additives may be used although it is better to obtain coarser sprays through appropriate nozzle selection and use wherever possible. When a drift control additive is used, read and carefully observe the cautionary statements and all other information appearing on the additive label, and be certain of compatibility with the tank mix and nozzle types being used before selecting any adjuvant types.

ROTATIONAL RESTRICTIONS A 30-day plant back interval for all crops not listed on the label.
