Problems to be Noted when Using "Trichlorfon"

(a) Cannot be used with or in combination with alkaline drugs. Because trichlorfon is an organophosphorus preparation, if it meets with basic drugs or alkaline substances, it will increase its toxicity, causing poisoning and even death of livestock. Sodium bicarbonate, artificial salt, Jianwei San, various sodium salts of sulfa drugs, soft soapy water, hard soapy water, lime water, etc. are all alkaline drugs, and they should be avoided or used together with “trichlorfon”. In addition, if ordinary water is alkaline hard water, it cannot be used to formulate trichlorfon solution. (b) Do not exceed the therapeutic dose. Because the treatment dose of "trichlorfon" is very close to the poisoning dose, with a slight care, livestock poisoning and even death will occur because of excessive doses. Therefore, in order to ensure the safety of livestock, we must first accurately determine its weight, and then accurately calculate the amount of weight. Then, what is the internal dose of “trichlorfon” for various livestock? 20--40 milligrams per kilogram body weight of cattle, the highest dose of 15 grams for one time; 30--50 milligrams per kilogram of body weight for donkey horses, one dose of 20 grams; 80 to 100 milligrams of pig per kilogram of body weight, 1 time The highest dose is 5 grams; sheep per kg body weight 80--100 mg, the highest dose of 5 grams; the goat is slightly more sensitive than the sheep, the amount is less, 50--70 mg per kg of body weight, the highest dose of 4 Grams. When trichlorfon is used orally, it should be formulated as a 1% - 3% solution. If the concentration is too low, the effect will be poor. If the concentration is too high, the side effect will be increased. To reduce the irritation to the stomach of the animal, it should be mixed with the appropriate amount of starch. With the application. (3) Poultry cannot be deterred with "trichlorfon". Because "trichlorfon" belongs to organophosphorus pesticides, chickens, ducks, geese and other poultry are particularly sensitive to organophosphorus pesticides. There are three reasons for this: First, organophosphorus pesticides can invade birds' brains; and secondly, organophosphorus pesticides enter poultry. Can cause poultry neurological disorders; Third, the poultry's hydrolysis of organic phosphorus formulations is particularly weak, that is, the natural detoxification ability of organophosphorus formulations is particularly low. Therefore, in addition to the use of dilute 0.1%--0.15% trichlorfon solution for external use of the affected part of the knee plague, it is absolutely impossible to use the "trichlorfon" orally to treat the insecticides of poultry.
