摘　　要：研究了一种以烯唑醇为活性组分的新型高分子缓释杀菌剂的制备和应用。将(E)-(RS)-1-(2,4-二氯苯基)-4,4-二甲基-2-(1,2,4-三唑-1-基)-1-戊烯-3-醇,以4,4′-二苯基甲烷二异氰酸酯(MDI)为架桥剂,通过化学反应接枝在聚乙烯醇高分子载体上,得到悬垂侧链带有生物活性片断的高分子型化学缓释杀菌剂。该高分子缓释杀菌剂在模拟的应用环境中,经水解和/或微生物降解等过程,能以有效剂量持续释放出具有杀菌性的活性组分,其杀菌活性与烯唑醇基本一致,持效期至少30d。A method for preparing novel, biodegradable fungicide-polymers containing Diniconazole ((E)-(±)-1-(2,4- dichlorophenyl)-2-(1,2,4-triazol-1-yl)-4,4-dimethyl-1-penten-3-ol) by reacting an isocyanate derivative of Diniconazole with polyvinyl alcohol was investigated, and a novel pesticide-polymer system in which the pesticide is chemically bonded to the polymer was obtained. The polymeric fungicide would release the active agent in a reasonable amount, by the processes of hydrolysis and/or bio-degradation. Its biochemical performance was coincidental with Diniconazole in the applied medium, measured by the prime biochemical test and its bioactive would last for at least 30 days.
