Effect of bacterial manure pouring root on growth and induced diseaseresistance of Poa pratensis

Biofertilizer plays dual roles in encouraging growth and improving disease resistance of plants. An experiment was conducted to develop a new biofertilizer by determining the effect of different combination of antagonistic bacteria and softguard fertilizer and Double?Green on disease indexes of Pythium graminicola, leaf width, and defense enzyme activities of Poa pratensis. The results of this study showed that antagonistic bacteria was best for the induced disease resistance of P. pratensis because it increased the content of POD, PAL, PPO, 1,3glucanase and SOD activities of P. pratensis. The softguard fertilizer and Double?Green encouraged the growth of P. pratensis when compared to antagonistic bacteria. Mixed application of CE antagonists bacteria and fertilizer improved the induced disease resistance rather than growth of P. pratensis.
