Abstract
A laboratory experiment was carried out according to the randomized complete design (RCD) during the season of 2022- 2023 to study the effect of Trichoderma harzainum, Bacillus subtilis and Naphthalene acetic acid. The results showed that the biological agent T. harizanium achieved an antagonistic ability against F. nygamia amounted 1.25 according to the Bell scale, the concentration 300 mg/l of NAA led to inhibiting of F. nygamia 100%, compared to the control treatment 0%, in comparison, the concentrations 300mg/L of NAA did not cause any inhibitory effect on T. harizanum 0%, the Uniform fungicide at concentrations (100-900) mg/L caused inhibition of F. nygamia, which reached 24.82, 57.78, 89.26 and 100% respectively compared to the control treatment 0%.
