Popis:	In mulberry (Morus alba L.), various individual strains of plant growth-promoting rhizobacteria (PGPR) and synthetic analogs of naturally occurring plant activators have demonstrated their potential to elicit induced systemic resistance (ISR) against either brown leaf spot (Cercospora moricola) or leaf rust (Cerotelium fici) diseases. However, these biological and chemical elicitors have not been evaluated so far against multiple infections of both these diseases which commonly occur during the post-rainy season. The present study was therefore aimed to assess the capability of PGPR strains and chemical plant activators, as individual and in integration, in elicitation of ISR against multiple infections. Three PGPR strains, Azotobacter chroococcum strain Azc-3, Bacillus megaterium strain Bm-1 and Pseudomonas fluorescens strain Psf-4, and plant activators, acetyl-salicylic acid (ASA), sodium salicylate (NaS) and 4-amino-n-butyric acid (ABA) were selected for the study. Under in vitro tests, all th...
