TY - JOUR ID - TI - Antagonistic effects of Securigera securidaca extracts, Bacillus cereus and Pseudomonas fluorescens against Aspergillus sp., Fusarium solani, and Rhizoctonia sp. in vitro AU - Hussein Ali Salim and Ahmed Y. Hassan PY - 2022 VL - 14 IS - 1 SP - 78 EP - 85 JO - Euphrates Journal of Agricultural Science مجلة الفرات للعلوم الزراعية SN - 20723857 AB - The study was carried out in the Diyala Agriculture Directorate, Plant Diseases Laboratory, during the year 2021 to evaluate the performance of Securigera securidaca concentrations (5%, 10%, and 15%) and two bacteria Bacillus cereus and Pseudomonas fluorescens against Aspergillus sp, Fusarium solani, and Rhizoctonia sp in vitro. The results showed that the extract concentrations 5,10 and 15% of S. securidaca inhibited the mycelial growth of Aspergillus sp. with inhibition percentage 45.9 %, 55.2 % and 39.4 % respectively. The highest inhibition effect of plant extract on the mycelial growth of Fusarium solani was 49.9% at the concentration 5%, while the inhibition percentage was 22.3% and 26.5% at the concentrations 10 and 15% respectively. The concentration 15% was superior in inhibition of mycelial growth of Rhizoctonia sp. 58.1%, followed by the concentration 5% and 10%, which reached 52.0% and 41.6% respectively. The bacteria P. fluorescens inhibited the mycelial growth of Aspergillus sp.,Fusarium solani and Rhizoctonia sp. with inhibition percentage 15.2 %, 22.4% and 61.1% respectively, whereas the bacteria B. cereus inhibited the mycelial growth of previous fungi with inhibition percentage 12.4 %,18.3 % and 58.8 % respectively.
