3.3.7. Endogenous Hormones

The results in (Figure 8) highlighted that *Fusarium* infection decreased IAA but increased SA and ABA contents in the infected control plants over the healthy control plants. However, applying cyanobacteria through different modes to the infected plants significantly increased the levels of IAA and SA hormones but decreased ABA concentrations over the infected control plants. The data (Figure 8) revealed that the maximal increase in the IAA contents was observed in the infected plants treated with *D. muscorum* and *A. oryzae* through the soil treatment mode. In addition, the highest growth in the SA contents was recorded by the infected plants treated with *A. platensis* through the foliar spraying. On the other hand, infected plants treated with *A. platensis* through foliar spraying showed the least reduction in ABA concentration in our research.
