DIRECTIONS FOR USE
Rates per 1,000 litres are based on dilute spray mixture. Copper Oxychloride 50 may be used in low volume or concentrate sprays by increasing the dosage to apply the same quantity of Copper Oxychloride 50 per hectare as would normally be applied when spraying dilute mixtures. Apply in sufficient water for thorough coverage of all plant parts; this volume depends on spray equipment and size of plants. The spray tank should be partially filled with water and the required Copper Oxychloride 50 added with the agitator running. Keep agitator running during filling and spraying operations. The use of a surfactant (spreader sticker) according to manufacturer's recommendations will improve coverage of spray. May be used up to 2 days before harvest.
DO NOT apply this product in a way that will contact workers or bystanders, either directly or through drift.
Only protected handlers may be in the area during application.
DO NOT apply this product directly to freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands), estuarine/marine habitats.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
DO NOT apply by air.
BUFFER ZONES
Field sprayer application:
DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty.
DO NOT apply with spray droplets smaller than the American Society of
Agricultural Engineers (ASAE) medium classification.
Boom height must be 60 cm or less above the crop or ground.
Airblast application:
DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty.
DO NOT direct spray above plants to be treated.
Turn off outward pointing nozzles at row ends and outer rows.
DO NOT apply when wind speed is greater than 16 km/hr at the application site as measured outside of the treatment area on the upwind side.
Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held or backpack sprayer and spot treatment.
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrublands), sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, eservoirs and wetlands) and estuarine/marine habitats.
RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, please note that Guards man Copper Oxychloride 50 contains a Group M2 fungicide. Any fungal population may contain individuals naturally resistant to Guardsman Copper Oxychloride 50 and other Group M2 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 Guardsman Copper Oxychloride 50 or other Group M2 fungicides with different groups that control the same pathogens.
Use tank mixtures with fungicide 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 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 certifi ed crop advisors for any additio nal pesticide resistance- management and/or IPM recommendations for specific crops and pathogens.
COMPATABILITY
