In this study, the effect of six commercial biocontrol strains, Bacillus pumilus INR7, B. megaterium P2, B. subtilis GB03, B. subtilis S, B. subtilis AS and B. subtilis BS and four indigenous strains Achromobacter sp. B124, Pseudomonas geniculate B19, Serratia marcescens B29 and B. simplex B21 and two plant defense inducers, methyl salicylate (Me-SA) and methyl jasmonate (Me-JA) were assessed on suppression of wheat take-all disease. Treatments were applied either as soil drench or sprayed on shoots. In the soil drench method, the highest disease suppression was achieved in treatment with strains INR7, GB03, B19 and AS along with two chemical inducers. Bacillus subtilis S, as the worst treatment, suppressed take-all severity up to 56%. Both chemical inducers and bacterial strains AS and P2 exhibited the highest effect on suppression of take-all disease in the shoot spray method. Bacillus subtilis S suppressed the disease severity up to 49% and was again the worst strain. The efficacy of strains GB03 and B19 decreased significantly in the shoot spray method compared to the soil drench application method. Our results showed that most treatments had the same effect on take-all disease when they were applied as soil drench or sprayed on aerial parts. This means that induction of plant defense was the main mechanism in suppressing take-all disease by the given rhizobacteria. It also revealed that plant growth was reduced when it was treated with chemical inducers. In contrast, rhizobacteria not only suppressed the disease, but also increased plant growth.

The ability of fluorescent pseudomonads of cotton rhizosphere of induction of systemic resistance (ISR) against bacterial blight of cotton was investigated. Of the 21 isolates tested, 19 were observed to increase the resistance of plants. This was demonstrated by a lower percentage of infected leaf area. On the basis of growth promotion and ISR induction ability, isolates 148, 35Q, 16Q and 113 were selected for further investigations. All isolates increased the resistance of plants, and per cent of infected area on leaves of these treatments were lower than those control of plants. Levels of peroxidase (PO) and phenylalanine ammonia lyase (PAL) activity in the leaves of bacterized plants with selected isolates were similar to that in control plants, but after inoculation of leaves with the pathogen, the amount of these enzymes increased in bacterized plants to high levels. The increase of enzyme activity in control plants was low after inoculation.
