Usage: 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. Storage: Sealed tightly and stored away from light in a cool and dry place. Place of origin: China. Validity: 2 years Packing: 1kg/foil bag, or 25kgs/carton drum Specification Tests Specification Result Appearance White to yellowish crystalline powder Qualified Identification UV: conform Qualified HPLC:conform with spectrum of standard sample Qualified B1 content,% (calculated on the water free basis) B1≥90.0% 95.6% Related subatance Individual impurity,% ≤1.5% 0.5% The sum of total impurities peaks except two main peaks,% ≤6.0% 3.0% Disregard limit,% ≤0.05% ＜0.05% Water,% ≤3.0% 1.0% Conclusion The results conform with Enterprise standard Competitive Advantages Well and High Quality Control , Prompt Delivery , Competitive Prices , Earth-friendly Products , Small Order Acceptable
