Premix concentrate by adding tablet to 5 ℓ water, stirring continuously. Add diluted concentrate to approximately 25 ℓ water, stirring continuously. Add this premix to main bulk of water in the diptank or sprayrace sump and stir to complete dispersion.

The first 25 head of cattle dipped in a diptank should be redipped immediately before the rest of the herd.

Check efficiency of sprayrace before spraying cattle.

When hand spraying, ensure thorough wetting of animals using 12,5 ℓ per adult animal. Spray against lie of hair.

Spraying – dilute as follows:
1 x 20g Deltab to 100 litres of water OR
10 x 20g Deltab to 1000 litres of water
No boosting of spraywash is necessary.

Note: It is good husbandry to make only sufficient spraywash for each treatment session (i.e. 2, 5 litres per head plus sufficient spraywash to fill system) and to clean sprayrace systems after use, discarding remaining fouled wash.


  • Filling
    Use 1 x 20g Deltab tablet to 133.33 litres of water (average diptank of 15 000 litres requires 113 x 20g Deltab tablets to fill).
  • Replenishment
    Use 1 x 20g Deltab tablet to 110 litres of replenishment water or Head Count System.
  • Head Count System
    Use 1 x 20g tablet for every 45 animals previously dipped. Dilute according to directions and add to diptank prior to dipping. Water may be replaced as and when necessary. DO NOT ADD tablets during replacement of water.


  • Filling
    If the diptank was used for cattle dipping at the correct concentration, add 1 x 20g tablet per 200 litres of dip in the tank. When a diptank has previously been in use for cattle, the wash should be agitated by the passage of at least 25 head of cattle before commencing the dipping of sheep. If a fresh tank is being made up for sheep use 1 x 20g Deltab tablet per 100 litres of water.

    In the event of an outbreak of sheep scab, sheep MUST be dipped twice at statutory 8 – 10 day interval under Government supervision.
  • Replenishment: Woolled Sheep and Goats
    Before each dipping session, replenish the dipwash using 1 x 20g tablet for every 35 sheep or goats, irrespective of size, dipped at previous session. DO NOT ADD tablets during replacement of water.
  • Replenishment: Non-woolled Sheep and Goats
    As for woolled sheep, but add 1 x 20g Deltab tablet for every 110 sheep or goats dipped at previous session.

Note: After dipping woolled sheep, a small number of animals may show slight discomfort or unusual gait, but these effects are short-lived. Cattle can be dipped normally using the “head count” system after sheep have been dipped as above.

Spray birds until run-off.
1 x 20g tablet per 100 litres of water.


  1. Intensive control of ticks and flies
    When used as directed at weekly intervals it will provide intensive control of ticks and flies. All animals should be treated and interruption of the programme should be avoided.
  2. Extended treatment intervals
    Under circumstances of low tick or fly challenge it may be used, at the user’s discretion, at intervals greater than 7 days. In these circumstances, users are advised to make use of relevant vaccines to obtain optimal protection of their cattle against prevalent tick-borne diseases.
  3. Lice
    For control and prevention of lice, use two treatments with a three week interval. Annual preventative dipping is recommended.
  4. Post-dipping lameness
    If sheep are dipped on consecutive days Zinc Sulphate 10% should be added at the end of each day’s dipping. Although the condition is very rarely encountered in cattle tanks, it may occur.

Store in a cool, dry place.
