introduction

product name: eprinomectinorigin:it is a semi-synthesized product of fermented avermectin b1.chemical name: 4"-epi-4"-deoxy-acetylaminoavermectin b1formula and molecular weight: b1a c5oh75no14=913 b1b c49h73no14=899assay: based on drying, it contains of b1 not less than 90%.character: the product is white or light yellow crystalline powder.its melting point is 161-166°c.the product is soluble in methanol, ethanol and ethyl acetate, not soluble in water.usage: it is not only a broad spectrum and the most efficacious antiparasite drug of averrmectin kind, but also one of this kind of drugs with the lowest distribution coefficients in milk. tests show that the product, administered as 0.2mg/kg body weight, can effectively prevent and treat internal and external parasites of cattle and sheep. after administered to lactating cattle, the concentration ratio in milk to in plasma is less than 0.2. the residue amount of the drug in milk is low, so it does not need withdrawal period when administered to lactating cow; the residue amount in muscle is low, so there is also no withdrawal period in beef cattle.storage: keep closed and store away from light in a cool and dry place.

application

eprinomectin is a mixture of eprinomectins b1a and b1b in a 9:1 ratio, produced from a mixture of avermectin b1a and b1b. eprinomectin is used commercially as a topical endectocide (insecticide, miticide and nematocide) for cattle, including lactating dairy cows. like all avermectins and milbemycins, eprinomectin acts by binding to parasite glutamate-gated chloride ion channels and disrupts neurotransmission leading to paralysis and death of the parasite, mite or insect.

it is not only a broad spectrum and the most efficacious pesticide of avermectin kind, but also one of the lowest distribution coefficient of this kind in milk. trials show that the product with the concentration of 0.1mg/kg or 0.05mg/kg can efficaciously prevent seven kinds of nematodes parasitic on large intestine, small intestine and stomach of cattle and sheep, the efficacy is shown as at least 97%. when it is used to cow in milk, concentration ratio in milk to in plasma is not more than 0.2. it has the advantage over other drugs against nematodes parasitic on cow during milking.
