Chinese. 通过室内抑菌圈试验筛选用于制备防腐制剂的有效三唑类化合物,制备三唑制剂进行室内耐腐及野外耐久试验,以研究该制剂的防腐及防白蚁性能。结果表明：环丙唑醇（CY）、戊唑醇（TEB）和丙环唑（PPZ）对褐腐菌（GT）和白腐菌（TV）均具有很好的抑制效果。在室外地上（C3）使用条件下,对于CuPT（以PPZ、TEB和Cu为有效成分制备得到制剂,Cu∶PPZ∶TEB=50∶1∶1）各处理材,1.0kg・m. 3推荐为合理载药量;对于PT（以PPZ和TEB为有效成分制备得到制剂,PPZ∶TEB=1∶1）各处理材,200g・m. 3推荐为合理载药量。在室外与地接触（C4.1）使用条件下,对于CuCY（以Cu和CY为有效成分制备得到制剂,Cu∶CY=98.6∶1.4）各处理材,初步证明合理载药量在1.8～3.6kg・m. 3之间,但在白蚁危害十分严重地区,CuCY的载药量应大于3.6kg・m. 3。

The decay and termite resistant performance of formulations comprising triazoles was evaluated by laboratory sand block test and filed stake test. The inhibition zone test showed that cyproconazole （CY）, tebuconazole （TEB） and propiconazole （PPZ） were effective against brown rot fungi （GT） and white rot fungi （TV）. The result of laboratory sand block test showed that the rational retention was 200 g・m. 3 and 1.0 kg・m. 3 respectively for PT （PPZ∶TEB=1∶1） and CuPT （Cu∶PPZ∶TEB=50∶1∶1） at the circumstance of exterior above ground （C3 use class）. The result of field test showed that the rational retention should be more than 3.6 kg・m. 3 for CuCY （Cu∶CY=98.6∶1.4） at the circumstance of exterior ground contact （C4.1 use class） whereas the termite is very severe.
