Method for identifying true and false agricultural streptomycin
Agricultural streptomycins are antibiotics that have a systemic effect and are one of the most commonly used agents for the prevention and treatment of bacterial diseases. However, the reporters must remind farmers that when buying streptomycin for agriculture, they should not feel that drug prices are cheap, and they do not pay attention to the authenticity of drugs. When the reporter interviewed Yantai Haiyang last week, a large number of inferior agricultural streptomycins were found in the sheds of farmers in the area. According to the farmer, he bought 1.5 yuan a pack (7 grams) of streptomycin, he felt that such a cheap drug would still be fraudulent, he did not pay attention when he bought it, and he did not know how to distinguish between true and false. Identification of true and false streptomycin, the reporter recommended three methods: First, touch. Farmers can open the agricultural streptomycin package and touch it with hands. If they feel sticky, they are genuine; if the hands are smooth, they are inferior products. The second is dissolved in water. If the agricultural streptomycin is poured into water and dissolved for a few minutes, it is genuine; if it is only partially dissolved after stirring, it is a poor quality product. The third is to add warm water. The agricultural streptomycin is heated after adding water, if it becomes a colorless transparent liquid, it is genuine; if it is translucent jelly or sticky, it is inferior.
