plant growth-promoting rhizobacteria (pgpr) is an alternative to chemical pesticides against harmful microorganisms especially soil-borne diseases. rhizoctonia solani is one of the most important soil-borne fungal pathogens that causes serious damages to important crops. in this study, to screen successful pseudomonas bacterial isolates, the inhibition of pathogen growth was evaluated in-vitro....
activities of thirty bacterial strains obtained from plants rhizosphere in different areas against phytophthora drechsleri were assessed through in vitro and greenhouse experiments. dual culture and extracellular metabolites tests were used in in vitro assays. the bacterial strains inhibited growth of p. drechsleri, the highest inhibition zones was belonged to t17-4 strain with 61.904% in dual ...
to study the effects of biofertilizers on physiological and morphological characteristics, as well on essential oil content in dragonhead (dracocephalum moldavica), an experiment was conducted at tarbiat modares university in 2009. the studied factors were: vermicompost (0, 15, 30% v/pot), azotobacter (inoculated and non-inoculated), and phosphatic biofertilizer (inoculated and non-inoculated)....
