【摘要】 我们对新近合成的三唑类似物在小麦叶锈菌上进行活体生物活性的研究，其中有７个化合物有明显的生物活性。本文以２，２－二甲基－６－间甲基苯氧基－４－（１，２，４－三唑－１－基）己醇－３，下称ＰＩ－２６化合物，经室内不同浓度、不同施药方式及持效期对小麦叶锈菌进行活体生物活性的研究。该化合物的叶面喷洒和持效期结果与三唑酮相似，内吸传导低于三唑酮更多还原

【Abstract】 We have done the research of novel compounds 1,2,4-triazol derivatives bioactivities on wheat leaf rust in vivo.Seven of them have the significant bioactivities.In this paper,we took PI-26 as a sample to study on bioactivities of wheat leaf rust in vivo,with different methods,concentrations ,and lasting period.In our research PI-26 shows the same bioactivities with triademefon in foriage spray method,but the systemic activites is lower than triadimefon.We will study on the mode of action of PI-26 later.更多还原
