贵州省无公害茶园农药使用调查与特点分析

Investigation of Pesticides Applied in Guizhou Pollution-free Tea Plantations and Characteristic Analysis

为指导贵州省无公害茶园科学使用农药,以实地采访和发放问卷的形式,随机对贵州省5个茶产区的17个重点无公害产茶市(县)216名无公害种植农户、135家茶企业和56家农药销售店面进行无公害茶园农药使用品种调查。结果表明:贵州省无公害茶园具有较好的农药使用品种丰富度及安全性;以防治为目的农药品种使用较多,未见以预防为目的的农药品种;水溶性杀虫剂使用较多,生物源杀虫剂使用较少;不同茶产区差异较大,发达茶产区具有较高的农药种类丰富度和多样性。基于此,提出了贵州省无公害茶园农药品种的使用建议。
