Prevention of blowfly strike due to Wohlfahrtia magnifica on sheep.
The veterinary medicinal product is applied according to the following
recommendations:
Bodyweight (kg) Dose Volume (ml)10 - 202021 – 302431 - 5030>5036
(Guide dose volumes correspond to 0.7–2 ml [7.5–25 mg dicyclanil] per kg
bodyweight.)
To ensure administration of a correct dose, body weight should be determined as
accurately as possible; accuracy of the dosing device should be checked.
If animals are to be treated collectively rather than individually, they should be
grouped according to their bodyweight and dosed accordingly, in order to avoid
under- or overdosing.
Recommended for treatment in sheep 3 weeks post shearing. Shake the container
well before use.
The veterinary medicinal product must be applied with a manual or automatic dosing
gun, fitted with a spray nozzle, which guarantees the correct spreading of the
product on the fleece. Best results will be achieved by holding the gun approximately
45 cm from the sheep during application. Apply as a fan spray using a 4 stroke
method as shown in the pictogram along the spine of the animal in bands at least
10 cm wide from the middle of the shoulders and in an arc around the crutch and
tail. Half the dose should be applied along the spine with the remainder over the tail
and crutch area.
The veterinary medicinal product should be administered before or at the start of
predicted fly activity but is also suitable for use during the fly season.
The veterinary medicinal product will protect against fly strike for 8 weeks. It is good
agricultural practice to check animals regularly for fly strike.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
Target species: sheep
None known.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or the national competent authority via the
national reporting system. See package leaflet for respective contact details.
None.

Special precautions for safe use in the target species:
The veterinary medicinal product is best applied before an anticipated blowfly
challenge, or when a blowfly challenge is identified on or in the vicinity of the farm.
Established strikes may require a separate treatment with a knockdown insecticide.
It is recommended that animals with dirty back ends are dagged or crutched prior to
application. If dagging or crutching is undertaken in the weeks following application,
these animals should be re-treated, otherwise protection could be lost.
Do not apply during heavy rainfall, or when such conditions are expected. The
resulting wash out may reduce the protection period.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
•
veterinary medicinal product.
•
•
PVC trousers should be worn when handling the veterinary medicinal
product.
•
the affected parts of the body with soap and water.
•
•
•
•
If you need to handle sheep within 2 months after treatment, wear synthetic
rubber gloves and long trousers or coveralls. If sheep are wet wear
waterproof trousers.
Special precautions for the protection of the environment:
Treated sheep must be kept away from watercourses for at least one hour after
treatment. There is a serious risk to aquatic life if this advice is not followed.
None known.
Protect from frost.
Store in the original container.
Keep the container tightly closed, away from food, drink and animal feedstuffs.
Protect from direct sunlight.
Meat and offal: 7 days.
Not authorised for use in animals producing milk for human consumption.
