Interactions
Some organo-phosphorous insecticides can reduce metabolism rate and thus enhance deltamethrin toxicity. Do not mix any other insecticide or acaricide with Dectospot Spot-on Solution.
Amounts to be administered and administration route
The product should be applied using an appropriate application device:
-For the 250ml and 500ml presentations a graduated chamber attached to the container is used.
-For the 1 litre and 2.5 litre presentations it is recommended to use an appropriate applicator.
The recommended use of the application devices is illustrated below.
1. Use of the graduated chamber on the 250ml and 500 ml containers:
2.Attaching the 1 and 2.5 litre containers to the recommended applicator:
Dose:
Cattle:10 ml
Sheep: 5ml
Lambs (under 10 kg bodyweight or 1 month of age): 2.5ml
Administration: Apply a single dose with the special dispenser pack or the Dectospot Applicator on one spot on the mid-line of the back at the shoulders as directed on dispenser or applicator gun pack. For blowfly strike on sheep, see following specific indication directions.
Lice on cattle: One application will generally eradicate all lice. Complete clearance of all lice may take 4 - 5 weeks during which time lice hatch from the eggs and are killed. A very few lice may survive on a small minority of animals. Therefore, it may be necessary on rare occasions to re-treat an animal 6 - 8 weeks later.
Flies on cattle: To control biting and non-biting flies, frequency of treatment will depend on the numbers and species of flies present. Where horn-flies predominate, good control can be expected for 4 - 8 weeks. Treatment for fly control should not be repeated within four weeks.
Ticks on sheep: Application to the mid-point of the shoulders will provide useful control of ticks attaching to animals of all ages, for up to 6 weeks after treatment.
Keds and lice on sheep: Application to the mid-point of the shoulders of sheep in short or long fleece will reduce the incidence of a biting louse or ked infestation over a 4 - 6 week period after treatment.
N.B. For control of ticks, keds and lice on sheep, the fleece should be parted and Spot On applied to the skin of the animal.
When using the Dectospot applicator application to the skin can be achieved by inserting the T bar to separate the fleece and penetrate down to the skin level before squeezing the applicator handle.
Established blowfly strike on sheep: Apply directly to the maggot infected area as soon as the fly strike is seen. One application will ensure blowfly larvae are killed in a short time. Clipping out of stained wool before treatment is advisable.
Lice and ticks on lambs: Application to the mid-point of the shoulders will provide useful control of ticks for up to 6 weeks after treatment, and will reduce the incidence of biting lice over a 4-6 week period after treatment.
