How to dilute Entomozan and what dosage should be used for treating ticks on cows? - briefly
Dilute Entomozan 1 part concentrate to 999 parts water (approximately 10 ml per 10 L) and spray the solution on cattle, ensuring coverage of all skin surfaces. Apply at 0.5 ml of the diluted solution per kilogram of body weight, with a maximum of 50 ml per animal.
How to dilute Entomozan and what dosage should be used for treating ticks on cows? - in detail
Entomozan is a synthetic acaricide formulated as a liquid concentrate containing 250 g of active ingredient per litre. Effective control of bovine ticks requires a solution that delivers 1 mg of active ingredient per kilogram of animal body weight.
To prepare the spray solution, follow these steps:
- Determine the total live weight of the herd. For example, a group of 50 cows averaging 550 kg each has a combined weight of 27 500 kg.
- Multiply the total weight by the target dose (1 mg kg⁻¹) to obtain the required amount of active ingredient: 27 500 kg × 1 mg kg⁻¹ = 27 500 mg = 27.5 g.
- Convert the required active ingredient into volume of concentrate using the product concentration: 27.5 g ÷ 250 g L⁻¹ = 0.11 L, or 110 mL of the concentrate.
- Dilute the measured concentrate in clean water to a total volume that allows thorough coverage of the animals. A common practice is to use 10 L of water per 100 kg of live weight, yielding 275 L for the herd. Add the 110 mL of concentrate to the 275 L of water, mixing gently while the water is still flowing.
Administration guidelines:
- Apply the solution using a calibrated backpack or low‑pressure sprayer, ensuring even coverage of the entire body surface, especially the neck, dewlap, and udder where ticks congregate.
- Repeat the treatment after 7 days to interrupt the life cycle of newly hatched larvae.
- Record the date of each application for withdrawal monitoring.
Safety and regulatory considerations:
- Wear protective gloves, goggles, and a respirator during mixing and spraying.
- Avoid direct contact with skin and inhalation of aerosols.
- Observe the mandated withdrawal period of 48 hours before milk collection and 5 days before meat processing.
- Store the concentrate in a locked, ventilated area away from heat sources and incompatible chemicals.
By adhering to the calculated dilution ratio and the specified application volume, the acaricide will achieve the intended concentration on the animals, providing reliable tick control while complying with safety standards.
