How To Apply

CyLence Pour-On Insecticide is a ready-to-use solution applied using a graduated syringe, cylinder or standard sized dipper.

CATTLE:

Apply the required amount of solution directly along the top of the back and the top of the head of the animal.

The dosage applied depends on the weight of each animal. The following table shows the correct amount to apply. Note: Due to the small amount of material required, care must be taken to apply the correct dosage.

DO NOT apply more than once every 3 weeks. DO NOT apply more than 3 applications per year. For optimal lice control, an initial application followed by a second treatment 3 weeks later is recommended. Chewing lice (otherwise known as biting lice) (Mallophaga) will usually be eliminated within one week after the first treatment. Sucking lice (Anoplura) may persist on a few animals after the second treatment.

Leave a one-day interval between last treatment and slaughter. Consult a veterinarian before using on cattle under drug or other pesticide treatment. CyLence Pour-On Insecticide does not control Cattle Grubs.

SHEEP:

For treatment and control of Sheep Biting Lice (Bovicola ovis) and Sheep Keds (Melophagus ovinus), part the fleece and apply 2 mL of solution per 10 Kg body weight to all sheep within a flock directly along the top of the back in multiple locations. CyLence Pour-On Insecticide has been shown to have residual activity against sheep keds protecting sheep from re-infestation for up to 21 days.

DO NOT apply more than once every year. Leave a one-day interval between the last treatment and slaughter. There is no withdrawal time for milk. Consult a veterinarian before using on sheep under drug or other pesticide treatment.

Resistance Management:

For resistance management, CyLence Pour-On Insecticide is a Group 3 insecticide. Any insect population may contain individuals naturally resistant to CyLence Pour-On Insecticide and other Group 3 insecticides. The resistant biotypes may dominate the insect population if these insecticides are used repeatedly. 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 insecticide resistance:

● Where possible, rotate the use of CyLence Pour-On Insecticide 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 integrated pest management (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 the local extension specialist or certified crop advisors for any additional pesticide resistance-management and IPM recommendations for the specific site and pest problems in the area.

● For further information or to report suspected resistance, contact Bayer Animal Health at 1 888 663-5326.

NOTICE TO VETERINARIAN:

A small percentage of treated animals may experience a temporary skin sensation known as paraesthesia (characterized by one or more of the following signs: head tossing, tail twitching, restlessness and irritability) within 24 hours after application. Affected animals generally return to normal within 48 hours, without treatment.
