GENERAL INSTRUCTIONS (Cattle, Horses)

Bayticol is effective against sensitive strains of cattle tick but resistance may develop to any tickicide. If lowered level of control is experienced, resistance testing of your ticks is recommended.

Bayticol should be used at intervals of not more than 19-21 days to control cattle tick (Boophilus microplus). Control is not adversely affected by rainfall a few hours after treatment.

Bayticol controls Paralysis Tick (Ixodes holocyclus) and New Zealand cattle tick (Haemaphysalis longicornis) on cattle and horses. To control these ticks when active the treatment interval should be 10 days.

Bayticol is compatible with externally applied Buffalo Fly Sprays plus vaccination and normal management procedures such as castration and dehorning.

Bayticol may be used in water of any hardness. Softening agents should not be used.

DIP AND SPRAY MANAGEMENT (Cattle, Horses)

1. Volume. The volume of dip or sump should be accurately measured. Relevant volume levels should be marked on the dip wall or a dip stick. Sumps should be maintained in near-full condition. For efficient tick control, replenish before volume falls below recommended levels (See Table).

2. Mixing. Add required concentrate to twice its volume of water in a bucket, mix, then pour along the length of the dip, or across the surface of the sump. Stir thoroughly. In a plunge dip, use 20-25 cattle as stirrers. These must be dipped again. A spray-race sump should be stirred with a paddle and agitated vigorously with the pump. It is essential that the dip be stirred at the commencement of each day's dipping and after every replenishment.

3. Sampling. Stir dip or sump before sampling. In a plunge dip the sample should be taken from 1 metre below the surface at the jump end as the last animal is passing through the dip. In a spray-race, on completion allow drainings to reture to sump, stir with paddle and pump and sample from below the surface immediately.
