NY 620-2002

Agricultural authorities and pesticide manufacturers use this standard to regulate the production and quality control of carbendazim and carbofuran suspension concentrates for seed dressing. It ensures key parameters such as active ingredient content, suspension rate, and pH value meet requirements, thereby guaranteeing seed treatment efficacy and crop safety. This standard is crucial for pesticide registration, market supervision, and safe user application.

农业部门和农药生产企业使用该标准来规范多·克悬浮种衣剂的生产和质量控制。该标准确保产品中有效成分含量、悬浮率、pH值等关键指标符合要求，从而保障种子处理效果和作物安全。它对于农药登记、市场监督和用户安全使用具有重要意义。

NY 620-2002 is a Chinese agricultural industry standard that specifies the technical requirements, test methods, marking, labeling, packaging, storage and transport of carbendazim and carbofuran suspension concentrates for seed dressing. The product contains two active ingredients, carbendazim and carbofuran, and is used for seed treatment. The standard defines indicators such as total active ingredient content, pH value, suspension rate, sieve analysis, viscosity, film-forming property, coating uniformity, coating shedding rate, low-temperature stability, and heat storage stability. Test methods include high-performance liquid chromatography for content determination, pH measurement, and suspension rate testing. This standard applies to the production and quality control of carbendazim and carbofuran suspension concentrates for seed dressing.
