Hydroponic culture experiments were conducted to investigate the effects of solublesilicon and inoculation with Sphaerotheca fuliginea on time-dependent changes in activities ofphenylalanine ammonia-lyase(PAL),polyphenoloxidase(PPO),peroxidase(POD)and lig-nin content in the leaves of Chinese white-flowered gourd(Lagenaria leucantha).

polyphenol oxidase(PPO) , catalase(CAT) and the content of phenolic compound in the leaves of 3 cucumber cultivars with different resistance to Sphaerotheca fuliginea after inoculation were studied .

50% EC of bamboo tar was used as agricultural fungicides against Rhizoctonia solani,Ustilaginoidea virens,and Sphaerotheca fuliginea in present study.
