The mycelial growth of Rhizoctonia solani was promoted by vanillic acid and syringic acid at levels of 0.1~1 mM/L, and it was inhibited remarkably by p-counaric acid of over 1mM/L and modestly by ferulic acid. The radial extent of mycelia of Fusarium solani was increased significantly by ferulic acid of 0.1~1 mM/L and limitedly by p-coumaric acid. vanillic acid had paradoxcial effects on the growth, positively at low levels and negtively at high levels, on which Syringic acid had a slight effect.

Yindi, a melon variety widely planted in recent years, were investigated in the paper. The results indicated that AZX from 100mg/L to 400mg/L treatment reduced significantly severity of downy mildews and powdery mildews, latent infection rate of fruits, and the disease incidence of postharvest pink rot and Fusarium rot. The treatment at 400mg/L of AZX showed the best control.
