| Abstract | ||
| Powdery mildew, caused by Erysiphe betae, is one of the most serious diseases affecting sugar beet plants globally. It causes a great loss in the root yield, sugar percentage, and quality of produced sugar. The current study aimed to evaluate the three biocontrol agents, intracellular or extracellular products of microalgae (Spirulina platensis, Nostoc muscorum and Anabaena oryzae), over two successive growing seasons 2020/2021 and 2021/2022 against E. betae under greenhouse and field conditions. Results showed that S. platensis and N. muscorum gave a good potential to control powdery mildew of sugar beet and improve their productivity as well as root yield quality under field conditions. Furthermore, induced plant defense by increasing the activity of resistance enzymes (peroxidase (PO) and polyphenoloxidase (PPO)) and phenolic compounds under greenhouse conditions. The results also showed that, the superiority effect of cell culture on biomass ethanolic extract of N. muscorum which highly achieve efficiency in management of disease. In overall, this study indicated the potential benefits of using microalgae to control powdery mildew in sugar beet. | ||
