*3.2. Effect of Cyanobacteria on Disease Index of Infected Pepper Plants*

Data presented in Table 1 reported that *F. oxysporum* shows a highly destructive effect on pepper plants that caused typical wilt symptoms with DI 83.33%. Applying cyanobacterial filtrate in the soil and foliar spraying highly protected plants against *Fusarium* wilt and lowered the *Fusarium* wilt disease symptoms caused by *F. oxysporum* compared with infected pepper plants. Data showed that spraying cyanobacteria was more effective than irrigation in soil, while foliar spraying with *A. platensis* showed high protection against *Fusarium* infection (95%), followed by *D. muscorum* (90%), then *A. oryzae* (69.9%).
