USE INFORMATION
DEVRINOL 10-G Herbicide does not control established weeds. It must be applied to freshly weeded soil before weeds germinate or during fall and winter months.
DEVRINOL 10-G Herbicide can be applied to newly planted container-grown stock after soil has settled from first watering, to field grown nursery stock, and to established plants.
DEVRINOL 10-G Herbicide needs mechanical incorporation (such as, power tiller), adequate irrigation or natural moisture (rainfall or snow) for optimum results. The treatment must reach the zone of weed seed germination.
If rainfall does not occur within 7 days for a spring or fall application or 2 days for a summer application (June, July and August), a shallow incorporation to a depth of 2.5 to 5 cm or an irrigation (sprinkler or flood) with sufficient water to wet the soil to a depth of 5 to 10 cm is necessary.

APPLICATION RATES
For control of the listed annual grasses and broadleaf weeds in the above ornamentals, nursery stock, container-grown stock, and ground covers, apply 45 kg of DEVRINOL 10-G Herbicide per broadcast hectare.
Cranberries: For the control of grass weeds (including rice cut-grass) apply 45-67 kg/ha. Apply only one application per year as a broadcast application. Application should be made in late winter (BC only) or spring - fall application is prohibited. If rainfall does not occur after treatment, irrigate with sufficient water to wet the soil to a maximum depth of 10cm.

Shrubs and Vines
Established grapes – For control of listed weeds, apply 45 kg/ha as a broadcast application. Refer to Use Information section for additional instruction on obtaining optimum performance.
Newly planted or established caneberries – blackberries, raspberries, boysenberries, loganberries - For control of listed weeds, apply 45 kg/ha as a broadcast application. Apply in the fall through early spring prior to weed emergence. Refer to Use Information section for additional instruction on obtaining optimum performance.
Highbush blueberries - For control of listed weeds, apply one (1) application per season of 45 kg/ha in a band. Apply in the fall through early spring prior to weed emergence. Do not apply to frozen ground. Do not apply within 70 days of harvest. Refer to Use Information section for additional instruction on obtaining optimum performance.
Cultivated lowbush blueberries - For control of listed weeds, apply one (1) application per season of 45 kg/ha in late fall / early spring when blueberries are dormant. Do not apply to frozen ground. Do not apply within 70 days of harvest. Refer to Use Information section for additional instruction on obtaining optimum performance.

Resistance-Management Recommendations
For resistance management, DEVRINOL 10-G Herbicide is a Group 15 herbicide. Any weed population may contain or develop plants naturally resistant to DEVRINOL 10-G Herbicide and other Group 15 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 resistance-management strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of DEVRINOL 10-G Herbicide or other Group 15 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 pesticide resistancemanagement and/or integrated weed-management recommendations for specific crops and weed biotypes.
