GENERAL INFORMATION

Authority 480 Herbicide is a selective soil applied herbicide for the con- trol of wild buckwheat, kochia, lamb’s quarters, and redroot pigweed in chickpeas, field peas, flax, sunflower and soybean.
Authority 480 Herbicide is formulated as a flowable (suspension con- centrate) containing 480 grams of the active ingredient, sulfentrazone, per litre, intended for dilution with water for application.
Authority 480 Herbicide is taken up by the plant roots and shoots.
Observe all instructions, mixing directions, application precautions and other label information of Authority 480 Herbicide.

STORAGE
STORE ABOVE 5 C TO KEEP PRODUCT FROM FREEZING. If frozen, thaw before use. If solid crystals are observed, warm material to above 15 C by placing container in warm location. Shake or roll container periodically to redissolve solids.
Do not use or store near heat or open flame.
Store in original containers only. Store containers in a dry location. Carefully open containers. After partial use, replace lids and close tightly. Do not put concentrate or dilute material into food or drink containers. Do not contaminate other pesticides, fertilizers, water, food, or feed by storage or disposal.
To prevent contamination store this product away from food or feed.

DISPOSAL
Do not reuse this container for any purpose. This is a recyclable con- tainer, and is to be disposed of at a container collection site. Contact your local distributor/dealer or municipality for the location of the nearest collection site. Before taking the container to the collectionsite:
1. Triple-rinse or pressure-rinse the empty container. Add the rinsings to the spray mixture in the tank.
2. Make the empty, rinsed container unsuitable for further use. If there is no container collection site in your area, dispose of the container in accordance with provincial requirements.
For information on disposal of unused, unwanted product, contact the manufacturer or the provincial regulatory agency. Contact the manufacturer and the provincial regulatory agency in case of a spill, and for clean up of spills.

SPRAY DRIFT MANAGEMENT
Minimizing spray drift at the application site is the responsibility of the applicator and the grower. The interaction of many equipment and weather-related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions.
Apply only when the potential for drift to areas of human habitation or areas of human activity, such as houses, cottages, schools and recreational areas is minimal. Take into consideration wind speed, wind direction, temperature inversion, application equipment and sprayer settings.
One of the most effective ways to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest droplets that provide sufficient coverage for pesticide performance. Applying larger droplets reduces drift potential but will not reduce drift if applications are made improperly or under unfavorable environmental conditions.

MIXING AND LOADING INSTRUCTIONS
Authority 480 Herbicide is a suspension concentrate intended for dilution with water. For best results, fill spray tank with one half of the volume of clean water needed for the area to be treated. Start the agitation system. Slowly add the Authority 480 Herbicide to the spray tank. Complete filling the spray tank to the desired level. Continuous spray tank agitation is required at all times to maintain a uniform spray solution. Make sure Authority 480 Herbicide is thoroughly mixed before application.

ROTATIONAL CROP GUIDELINES
The following table shows the minimum interval in months from the time of the last Authority 480 Herbicide application until Authority 480 Herbicide treated soil can be replanted to the crops listed as follows.
Rotational crops and replant intervals for Authority 480 Herbicide.
Rotational Crop - Replant Interval (Months)
12 Months - Alfalfa, Barley, Canola, Corn field, Spring and Durum wheat.
16 Months - Winter wheat.
24 Months - Corn sweet and pop, Lentils, Sorghum.
Anytime - Chickpea, Field pea, Flax, Soybeans, Sunflowers.
For crops listed in the rotational crop table, the minimum replant interval listed in the table must be observed. For crops not listed in the rotational crop table, A MINIMUM ROTATIONAL CROP INTERVAL OF 36 MONTHS must be observed and a representative bioassay of the field must be conducted with the rotational crop and adequate soil moisture to evaluate potential crop sensitivity.
If there is a lack of adequate or normal soil moisture due to drought conditions following an application of Authority 480 Herbicide, the minimum rotational crop interval listed in the table must be extended for one additional year and a representative bioassay of the field must be conducted with the potential rotational crop and adequate soil moisture to determine the crop sen- sitivity to Authority 480 Herbicide.

DIRECTIONS FOR USE (CHICKPEAS, FIELD PEAS, FLAX, SUNFLOWERS AND SOYBEAN)
When used as directed, Authority 480 Herbicide will provide control of the listed weeds in chickpeas, field peas, flax, sunflowers and soybean.
Authority 480 Herbicide may be applied preemergence or preplant AS A SINGLE GROUND APPLICATION. Authority 480 Herbicide can be applied prior to planting or up to 3 days after planting, but before seed germination. When applications after planting are delayed greater than 3 days, injury may occur if seeds are germinating. Authority 480 Herbicide applied near or after crop emergence may cause severe injury to the crop.
Sulfentrazone is persistent and will last in the soils (carryover) for one to two years. DO NOT APPLY AUTHORITY 480 HERBICIDE TO FIELDS PREVIOUSLY TREATED WITH AUTHORITY 480 HERBICIDE IN CONSECUTIVE  YEARS  (2  YEARS  (24  MONTHS).  In  case  of drought in any of those years, as ubsequent application of Authority 480 Herbicide should be further delayed by the equivalent number of years in which drought occurred. Authority 480 Herbicide requires one (1) to two (2) cm of rain or irrigation water to be effective. If adequate moisture from rainfall or irrigation is not received within 7 to 10 days of application, a shallow incorporation no deeper than 5 cm may be needed to obtain adequate weed control.
