• intros：{"brand_intro":"江苏扬农化工股份有限公司（简称扬农）是中国拟除虫菊酯原药生产的龙头企业，成立于1999年，总部位于江苏扬州。公司拥有全球最大的菊酯类农药生产基地，年产能超2万吨，是拜耳、先正达等跨国公司的原药供应商。扬农以\"中国菊酯\"为品牌战略，打破国外技术垄断，实现了从中间体到原药、制剂的完整产业链。其品控体系通过CNAS认证，产品出口至60多个国家。创始人程晓曦带领团队攻克了高效氯氰菊酯的绿色合成工艺，使生产成本降低40%，被誉为\"中国菊酯之父\"。","product_intro":"扬农4.5%高效氯氰菊酯乳油是国产菊酯的性价比之王，定位大众市场，广泛用于水稻、棉花、蔬菜及卫生害虫防治。核心卖点是\"高纯度原药+稳定乳化工艺\"，其原药含量≥97%，杂质少，药效稳定。适用场景包括稻飞虱、棉铃虫、菜青虫、蚊蝇等。相比进口产品，扬农价格仅为拜耳同类产品的1/3，但防效达到90%以上，尤其适合大规模统防统治。缺点是剂型为传统乳油，使用有机溶剂，对环境影响略大。","key_specs":{"有效成分含量":"4.5%高效氯氰菊酯","剂型":"乳油（EC）","亩用量":"20-30毫升/亩","持效期":"7-10天","适用作物":"水稻、棉花、蔬菜、果树","安全间隔期":"7天"}}
