GENERAL DIRECTIONS FOR USE RESISTANCE-MANAGEMENT RECOMMENDATIONS
For resistance management, Credit 45 Herbicide is a Group 9 herbicide. Any weed population may contain or develop plants naturally resistant to Credit 45 Herbicide and other Group 9 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistancemanagement strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of Credit 45 Herbicide or other Group 9 herbicides with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted.
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
Contact your local extension specialist or certified crop advisors for any additional pesticides resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
For further information or to report suspected resistance, contact Nufarm Agriculture Inc. at 1-800- 868-5444 or at www.nufarm.ca. 

GENERAL INFORMATION 
Do not apply this product using aerial spray equipment, except under conditions as specified within this label.
This product is highly toxic to aquatic and terrestrial plants. A buffer zone of 15 metres is required between the downwind point of direct application and the closest edge of sensitive terrestrial habitats. A buffer zone of 15 metres is required between the downwind point of direct application and the closest edge of sensitive aquatic habitats, and wildlife habitat at the edge of these bodies of water. Do not contaminate these habitats when cleaning and rinsing spray equipment or containers. When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixtures.
Visible effects on most annual weeds occur within 2 to 4 days but on most perennial weeds may not occur until 7 to 10 days.
Extremely cool or cloudy weather at treatment time may slow down activity of this product and delay visual effects of control. Visible effects are a gradual wilting and yellowing of the plant that advances to complete browning of above ground growth and deterioration of underground plant parts.
Un-emerged plants arising from underground rhizomes or root stocks of perennials will not be affected by the spray and will continue to grow. For this reason best control of most perennial weeds is obtained when treatment is made at late growth stages approaching maturity.
Always use the higher rate of this product per hectare within the recommended range when weed growth is heavy or dense, or weeds are growing in an undisturbed (non-cultivated) area.
Do not treat weeds under poor growing conditions such as drought stress, disease or insect damage, as reduced weed control may result. Reduced control may also occur when treating weeds heavily covered with dust.
This product does not provide residual weed control.
Heavy rainfall immediately after application may wash the chemical off the foliage and a repeat treatment may be required. Do not apply if rainfall is forecast for the time of application.
Do not mix with any surfactant, pesticide, herbicide oils or any other material other than water unless specified in this booklet. For best results, spray coverage should be uniform and complete. Do not spray weed foliage to the point of runoff.
Do not apply in greenhouses.

MIXING AND APPLICATION 
Apply these spray solutions in properly maintained and calibrated equipment capable of delivering desired volumes.
AVOID DRIFT - EXTREME CARE MUST BE USED WHEN APPLYING THIS PRODUCT TO PREVENT INJURING DESIRABLE PLANTS AND CROPS. Do not allow spray mist to drift since even minute quantities of spray can cause severe damage or destruction to nearby crops, plants or other areas on which treatment is not intended, or may cause other unintended consequences.  
Do not apply when winds are gusty or in excess of 8 kilometres per hour or when other conditions, including lesser wind velocities, will allow drift to occur. When spraying, avoid combinations of pressure and nozzle type that will result in fine particles (mist) that are more likely to drift.
ATTENTION: AVOID CONTACT WITH FOLIAGE, GREEN STEMS, OR FRUIT OF CROPS, DESIRABLE PLANTS AND TREES SINCE SEVERE INJURY OR DESTRUCTION MAY RESULT.
Reduced results may occur if water containing soil is used, such as water from ponds and unlined ditches.
Clean sprayer and parts immediately after using this product by thoroughly flushing with water. Do not contaminate water sources by disposal of wastes or cleaning of equipment.

MIXING AND APPLICATION EQUIPMENT INFORMATION MIXING 
For ground or industrial type sprayers:
Fill the spray tank with one-half the required amount of water.
Add the proper amount of herbicide see “Weeds Controlled”, “In-Crop Treatments” and “NonCropland Treatments” sections of this booklet
Mix well before adding the remaining portion of water. Placing the filling hose below the surface of the liquid solution will prevent excessive foaming. Removing hose from tank immediately will avoid back siphoning into water source. Use of mechanical agitators may cause excessive foaming. Bypass lines should terminate at the bottom of the tank. For use in knapsack sprayers, it is suggested that the proper amount of this herbicide be mixed with water in a larger container. Fill sprayer with the mixed solution.

WEEDS CONTROLLED 
ANNUAL WEED CONTROL WITH CREDIT 45 HERBICIDE
Credit 45 Herbicide, applied by itself, will not control volunteers from crops containing genetic resistance to glyphosate.
Allow at least 1 day after treatment before tillage
Annual weeds generally will continue to germinate from seed throughout the growing season. Repeat treatments may be necessary to control later germinating weeds, in some situations.

IN-CROP TREATMENTS PRIOR TO PLANTING AND EMERGENCE OF ALL CROPS 
This product may be applied prior to planting all crops for control of emerged weeds listed on this label. Ensure weeds are at the desired stage at the time of application. This product does not provide pre-emergent weed control and newly germinating weeds may be a problem in the crop.
APPLY BEFORE SEEDING OR TRANSPLANTING. This product may be applied prior to seeding or after seeding, but before crop emergence for control of emerged weeds in minimum and zero tillage cropping systems for all field crops. Applications made too far in advance of seeding may allow weeds to emerge between application and crop emergence, as this product does not provide residual weed control.

WEED CONTROL IN GLYPHOSATE TOLERANT CANOLA (i.e. varieties with genetic resistance to glyphosate) 
NOTE: ALWAYS USE PEDIGREED (CERTIFIED) CANOLA SEED DESIGNATED AS GLYPHOSATE TOLERANT. CANOLA WHICH IS NOT DESIGNATED AS GLYPHOSATE TOLERANT WILL BE DAMAGED OR DESTROYED BY THIS TREATMENT. DO NOT APPLY BY AIR Some short term visual yellowing may occur when Credit 45 Herbicide is applied at the late application (4 to 6 leaf) stage of the crop. This effect is temporary and will not influence crop growth, maturity or yield. Weeds will be more easily controlled and early crop competition avoided with applications made when the weeds are small. Control of weeds greater than 25 cm in height will be inconsistent, although some weeds may be controlled.
WEED CONTROL IN GLYPHOSATE TOLERANT CORN (i.e., varieties with genetic resistance to glyphosate) 
NOTE: ALWAYS USE PEDIGREED (CERTIFIED) CORN SEED DESIGNATED AS GLYPHOSATE TOLERANT. CORN WHICH IS NOT DESIGNATED AS GLYPHOSATE TOLERANT WILL BE DAMAGED OR DESTROYED BY THIS TREATMENT. DO NOT APPLY BY AIR 
WEED CONTROL IN GLYPHOSATE TOLERANT SOYBEAN (i.e. varieties with genetic resistance to glyphosate) 
NOTE: ALWAYS USE PEDIGREED (CERTIFIED) SOYBEAN SEED DESIGNATED AS GLYPHOSATE TOLERANT. SOYBEANS WHICH ARE NOT DESIGNATED AS GLYPHOSATE TOLERANT WILL BE DAMAGED OR DESTROYED BY THIS TREATMENT. DO NOT APPLY BY AIR Weeds will be more easily controlled and early crop competition avoided with applications made when the weeds are small. Control of weeds greater than 25 cm in height will be inconsistent, although some weeds may be controlled.

IN CROP SPOT TREATMENT: 
This product can be applied as an in-crop spot treatment in barley, corn, oats, soybeans, wheat, strawberry, blueberry, forage grasses and legumes including seed production. Applications should be made using the same rates and at the same growth stages as listed in the weed control tables above or use a 1 percent solution for annual weeds and quackgrass and a 2 percent solution for other perennial weeds (a 1% solution equals 1 litre Credit 45 Herbicide in 100 litres of spray solution). One or 2% solution should be applied to wet, but not run-off. Applications can be made using a boom sprayer, hose and handgun, or hand sprayer in accordance with instructions in the “Application Equipment” section. Spot treatments can be made up to heading of small grains, initial pod set on soy and dry beans, silking of corn and emergence of seed heads. The crop in the treated area will be killed. Take care to avoid drift for the same reason. DO NOT APPLY IF CROP GROWTH HAS ADVANCED BEYOND SEED SET. ALLOW 3 TO 5 DAYS FOR CREDIT 45 HERBICIDE TO TRANSLOCATE INTO ALL PLANT PARTS BEFORE GRAZING OR HARVESTING TREATED AREAS.

PRE-HARVEST APPLICATION: 
Rate: 2.0 L/ha (2.0-4.0 L/ha for forages)
Water Volume: 50-100 L/ha Weeds controlled: Quackgrass, Canada thistle, common milkweed, toadflax, dandelion and perennial sowthistle. Weed Staging: Quackgrass (4-5 green leaves and actively growing); Canada thistle and perennial sow thistle (at or beyond the bud stage and actively growing); Common milkweed (bud-bloom stage and actively growing)
Harvest Management Benefits:
This treatment may also dry down crop and weed vegetative growth. Extremely cool, wet and/or cloudy weather conditions between the time of application and the anticipated harvest date may slow down activity of this product, thereby delaying crop drydown and harvest date.
Note: DO NOT APPLY BY AIRCRAFT; earlier application may reduce crop yield and/or quality, and may lead to excess glyphosate residues in the crop.

POST HARVEST APPLICATION: 
This product may be applied in the fall as a postharvest stubble treatment for control of perennial weeds such as quackgrass and Canada thistle. Allow weeds to regrow to the desired stage (20-25 cm tall for quackgrass and Canada thistle) before application and ensure they have a high proportion of green coloration. Straw should be removed or evenly spread to allow for proper regrowth and spray coverage. Heavy frosts prior to application may decrease control.
TREE, VINE, BERRY AND OTHER CROPS 
This product is recommended for annual and perennial weed control in various crops listed below, or for site preparation prior to transplanting tree and vine crops. Applications may be made with boom equipment, shielded sprayers, hand-held and high volume orchards guns, or with wiper applicator equipment (orchards, vineyards, cranberry and strawberry only). Do not apply more than 28 litres of this product per hectare per year. Extreme care must be exercised to avoid contact of herbicide solution, spray, drift, or mist with foliage or green bark of trunk, branches, suckers, fruit, canes of blueberry bushes, or other parts of trees or vines. Contact of this product with other than matured brown bark can result in serious crop damage.
