摘　　要：以杀菌剂烯唑醇1为底物与丙烯酰氯2反应合成了具有生物活性的可聚合单体(±)-(E)-1-(2,4-二氯苯基)-2-(1,2,4-三唑-1-基)-4,4-二甲基-1-戊烯-3-醇丙烯酸酯3,以IR,MASS和1H NMR对其化学结构进行了表征。该生物活性单体3与丙烯酸4共聚制得聚合物5。田间试验结果表明,以合成的杀菌聚合物5配成18%烯唑醇高分子缓释杀菌剂,对小麦纹枯病具有优异的防治效果,2、4、8 g a.i./100kg种子3个处理剂量,防效分别为56.82%、67.18%和81.00%,优于对照药剂12.5%烯唑醇WP的防治效果。A bioactive monomer 3, （±）-（E）-1-（2,4- dichlorophenyl）-2-（1,2,4-triazol-l-yl）-4,4-dimethyl-1-penten-3- ol-acrylate, was synthesized by reacting diniconazole 1 with acryloyl chloride 2, and its structure was confirmed by IR, MASS and ^1H NMR spectroscopy. The fungicide-polymer 5 was obtained with the radical copolymerization of 3 and acrylic acid 4. The results of field trial showed that diniconazole 18% slow-release polymeric fungicide from 5 provides better control of wheat Rhizoctonia solani Kuhn than diniconazole 12.5% wettability powder, and 56.82%, 67.18% or 81.00% efficacy was obtained when the dose was 2, 4, 8 g a.i./100kg seed, respectively.
