1. Cannot be combined with or used with alkaline drugs. Trichlorfon is an organophosphorus preparation. When it meets with alkaline substances, it will produce highly toxic dichlorvos and cause poisoning in livestock. In severe cases, it can cause death. Therefore, it cannot be combined with or used with sodium bicarbonate, artificial salt (combined artificial mineral salt), Jianweisan, and various alkali repellants such as sodium salt, soft soapy water, hard soapy water, and lime water.
2. Can not be used to deworm chickens and pregnant animals. Trichlorfon is a broad-spectrum anthelmintic drug for veterinary use. It is safe and effective for pigs, cattle, sheep, horses and other livestock, but it is banned for chickens. At the same time, the female offspring after pregnancy can not use trichlorfon, otherwise it will lead to abortion of the female.
3. It is necessary to strictly control the dosage used. Excessive doses cause poisoning and even death in livestock. The safe use dose of livestock should be calculated and determined according to the sensitivity and weight of different livestock to trichlorfon. Generally, the amount of cows per kilogram of body weight should be 20 mg to 40 mg, and the maximum dose should not exceed 15 g; horses, mites and pupa should be 30 mg to 50 mg per kilogram of body weight, and the maximum dose should not exceed 20 g; The weight of kilograms is 80 mg to 100 mg, the maximum dose should not exceed 5 g; the sheep should use 80 mg to 100 mg per kg of body weight, and the highest dose is 5 g; the goat is more sensitive than sheep, and the dosage should be appropriately reduced. Generally, the weight per kg is 50 mg to 70 mg, the maximum dose should not exceed 4 grams.
4. Formulation concentration. When formulating the oral solution of trichlorfon, the concentration should be between 1% and 3%. This is because the effect of too low a concentration is not good, and the concentration is too high, the side effects are increased. In order to alleviate the irritation of trichlorfon on the stomach, it is good to take with the appropriate amount of starch.
