Do not enter or allow entry into treated areas during the restricted-entry interval (REI) of 12 hours or until sprays have dried.

Tank Mixtures
In some cases, tank mixing a pest control product with another pest control product or a fertilizer can result in biological effects that could include, but are not limited to: reduced pest efficacy or increased host crop injury. The user should contact Dow AgroSciences Canada Inc. at 1-800-667-3852 or www.dowagro.ca for information before mixing any pesticide or fertilizer that is not specifically recommended on this label. The user assumes the risk of losses that result from the use of tank mixes that do not appear on this label or that are not specifically recommended by Dow AgroSciences Canada Inc.

Application Instructions
Carefully read, understand and follow label use rates and restrictions. Apply TwinGuard as a foliar spray at the rate indicated for target pest. The low rates may be used for light infestations of the target pests and the higher rates for moderate to heavy infestations. Apply the amount specified with properly calibrated ground spray equipment. Proper application techniques help ensure thorough spray coverage and correct dosage for optimum insect control.

Mixing Instructions

Fill the spray tank with water to about 1/2 of the required spray volume. Start agitation and add the required amount of TwinGuard Insecticide. Continue agitation while mixing and filling the spray tank to the required spray volume. Maintain sufficient agitation during application to ensure uniformity of the spray mix. Do not allow water or spray mixture to back-siphon into the water source.

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 and Biological Engineers (ASABE) fine classification. Boom height must be 60 cm or less above the crop or ground. Apply in sufficient spray solution to ensure thorough coverage of plant foliage. Use a minimum of 100 litres of water per hectare for field sprayer applications.

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/h at the application site as measured outside of the treatment area on
the upwind side. Apply in sufficient spray solution to ensure thorough coverage of plant foliage. Use a minimum of 500 litres of water per hectare for airblast applications.

DO NOT APPLY BY AIR


CROP: POME FRUITS (Crop Group 11-09): apple, Asian pear, azarole, Chinese quince, crabapple, Japanese quince, mayhaw, medlar, pear, quince, tejocote.
Observe a minimum treatment interval of 7 days and a preharvest interval of 7 days. Do not make more than 2 applications per growing season. DO NOT apply this product during crop flowering period or when flowering weeds are present in the treatment area. DO NOT APPLY BY AIR.

PEST: Aphids – green apple aphid, rosy apple aphid
RATE (g/ha): 250
PEST: San Jose scale
RATE (g/ha): 250-500
PEST: Woolly apple aphid (suppression only)
RATE (g/ha): 250
APPLICATION TIMING: Monitor the crop on a regular basis. Consult local authorities to determine threshold numbers and the most effective time to apply control measures in your local area. Thorough coverage is essential for good control.
For San Jose scale, apply when crawlers are active.

PEST: Codling Moth, Oriental Fruit Moth
RATE (g/ha): 500
APPLICATION TIMING: For the control of each generation, apply at first egg hatch based on pheromone trap catches and degree days after biofix dates. These pests must be controlled before the larvae penetrate the fruit so early timing is critical. Repeat at 14 day intervals to maintain control depending on pest pressure. 

PEST: Obliquebanded & Threelined (Pandemis) Leafrollers
RATE (g/ha): 250-500
APPLICATION TIMING: For the control of the over wintering (spring) generation, apply when larvae have emerged and are actively feeding but before they roll up in the leaves. Under high insect pressure, an application timed to target the overwintering generation is recommended to reduce summer populations.
For control of the summer generation, apply at first egg hatch as determined by monitoring adult moth flights. Repeat in 14 days if monitoring of populations indicates a second application is required. Use the higher rate under high pest pressure and/or larger larvae.

PEST: Spotted & Western Tentiform Leafminers
RATE (g/ha): 250-500
APPLICATION TIMING: Apply at egg hatch as determined by monitoring or at the first sign of sap-feeding on the leaves to control leafminers. Use the higher rate under high pest pressure.

PEST: Apple Maggot
RATE (g/ha): 500
APPLICATION TIMING: For the suppression of this pest, apply 7-10 days after the first apple maggot fly is caught on yellow scented sticky boards near or in the orchard. Repeat in 14 days if populations warrant.

PEST: Plum Curculio
RATE (g/ha): 500
APPLICATION TIMING: For the suppression of this pest, monitor trees along the edge of the orchard or adjacent wild trees for the first sign of feeding damage after bloom. Repeat in 14 days if populations warrant.

CROP: STONE FRUITS (Crop Group 12-09): American plum, apricot, beach plum, black cherry, Canada plum, cherry plum, Chickasaw plum, chokecherry, Damson plum, Japanese apricot, Japanese plum, Klamath plum, Nanking cherry, nectarine, peach, plum, plumcot, prune plum, sloe, sweet cherry, tart cherry
Observe a minimum treatment interval of 7 days and a preharvest interval of 7 days. Do not make more than 2 applications per growing season. DO NOT apply this product during crop flowering period or when flowering weeds are present in the treatment area. DO NOT APPLY BY AIR.

PEST: Oriental Fruit Moth
RATE (g/ha): 500
APPLICATION TIMING: For the control of each generation, apply at first egg hatch based on pheromone trap catches and degree days after biofix dates. These pests must be controlled before the larvae penetrate the fruit so early timing is critical. Repeat at 14 day intervals to maintain control depending on pest pressure.

PEST: Obliquebanded & Threelined (Pandemis) Leafrollers
RATE (g/ha): 250-500
APPLICATION TIMING: For the control of the over wintering (spring) generation, apply when larvae have emerged and are actively feeding but before they roll up in the leaves. Under high insect pressure, an application timed to target the overwintering generation is recommended to reduce summer populations.
For control of the summer generation, apply at first egg hatch as determined by monitoring adult moth flights. Repeat in 14 days if monitoring of populations indicates a second application is required. Use the higher rate under high pest pressure and/or larger larvae.

PEST: Aphids – green peach aphid, mealy plum aphid
RATE (g/ha): 250
APPLICATION TIMING: Monitor the crop on a regular basis. Consult local authorities to determine threshold numbers and the most effective time to apply control measures in your local area. Thorough coverage is essential for good control.

PEST: San Jose scale
RATE (g/ha): 250-500
APPLICATION TIMING: For San Jose scale, apply when crawlers are active

CROP: POTATOES
Observe a minimum treatment interval of 7 days and a pre-harvest interval of 7 days. Do not make more than 2 applications per growing season. Use a minimum spray volume of 100 L/ha.
DO NOT APPLY BY AIR

PEST: Aphids
RATE (g/ha): 200
APPLICATION TIMING: Monitor the crop on a regular basis. Consult local authorities to determine threshold numbers and the most effective time to apply control measures in your local area. Thorough coverage is essential for good control. Repeat application if monitoring indicates aphid population is sufficiently high.

PEST: Colorado Potato Beetle
RATE (g/ha): 200-300
APPLICATION TIMING: Time the application for egg hatch or small larvae. Use the higher rate for higher pest pressure or for larger larvae. A repeat application in 7 to 14 days may be necessary depending on pest pressure.

PEST: European Corn Borer
RATE (g/ha): 200
APPLICATION TIMING: Monitor egg laying and egg hatch to determine application timing. Time the application to coincide with peak egg hatch.

RESISTANCE MANAGEMENT RECOMMENDATIONS

For resistance management, please note that TwinGuard Insecticide contains both Group 4C and Group 5 insecticides. Any insect population may contain individuals naturally resistant to TwinGuard Insecticide and other Group 4C or Group 5 insecticides. The resistant individuals may dominate the insect population if these insecticides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but are specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay insecticide resistance:
Where possible, rotate the use of TwinGuard Insecticide or other Group 4C or Group 5 insecticides with different groups that control the same pests.
Use tank mixtures with insecticides from a different group when such use is permitted.
Insecticide use should be based on an IPM program that includes scouting and record keeping, and considers cultural, biological and other chemical control practices.
Monitor treated pest populations for resistance development.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for the specific site and pest problems in your area.
For further information or to report suspected resistance contact Dow AgroSciences Canada Inc. at 1-800-667-3852 or at www.dowagro.ca.
