Abstract: In order to find novel plant fungicides targeting Valsa mali with high activity, fifteen triamino substituted 1,3,5-triazine compounds bearing 2-amino-4,6-dimethyl-5-(un) substituted pyrimidine were designed according to the antifungal characteristics of triazine and pyrimidine and the superposition principle of reinforcement of biological activity. These compounds were synthesized by amino substitution using cyanuric chloride as the starting material, and their structures were characterized and determined by 1H NMR, ESI-MS and elemental analysis. The antifungal activity against Valsa mali of the new compounds were evaluated and the results showed that a majority of the compounds have notable inhibitory activity against Valsa mali. For examples, at the concentration of 200 μg/mL, compounds 2aa, 2ba, 2ca, 2da, 3ba and 3ea have the  inhibition rate of 96.33%, 98.17%, 97.25%, 97.71%, 98.39% and 94.50%, respectively, and have the inhibition rates above 74% at the concentration of 100 μg/mL, which suggest that such triamino substituted triazine compounds have the potential applications in further development for new fungicides.
