Figure 1. Pyrenophora teres. a; net form net blotch symptoms on a barley leaf. b; septate and branched (pointed by the arrow) mycelium. c; conidia with five and six (pointed) septa. Photo a, was photographed using Sony camera while micrographs b and c, were photographed using infinix Note 4 smartphone camera. The micrographs were at 1000X magnification

Figure 2. Petri plates showing the rear views of fungal pathogens isolates co-cultured with the antagonistic bacteria. In ‘A’, (D. teres) inhibition of mycelial growth towards the bacterium is clearly evident. B; The inhibition of R commune mycelia by the bacteria is not effective

Figure 4. Figures depicting the effect of bacterial volatiles (sealed plate method) on the growth of R. commune. Both represent 18 days old colonies. ‘A’ represent the colonies having the bacteria growing on the lower plate while ‘B’ represents the plates having non inoculated media (PDA) on the lower plate

Figure 5. Effects of P. polymyxa volatiles on the growth rate of R. commune

Figure 7. Different reactions by barley to D. teres fsp teres. A₁; plants inoculated with D. teres f. sp teres alone, B₁;plants inoculated with D. teres f. sp teres and the normal concentration of the crude bacterial extract. C₁; plants inoculated with D. teres fsp teres and double concentration of the crude bacterial extract. D₁; plant inoculated with D. teres f. sp teres and Orius (a chemical fungicide). E₁; non-inoculated plants. The pictures in the lower row provides detailed evidence of the lesions (or lack of ) of the corresponding plants above them
