Abstract
Wheat is an important agronomic staple crop compared with other cereals. Many factors, including abiotic and biotic stresses, can reduce wheat products, such as attacks by the insect-like aphid. The technologies of moringa leaf extracts (MLE) and plant growth-regulating rhizobacteria for the control of aphid attacks were studied in the current experiment to determine the effectiveness of non-pathogenic bacteria Pseudomonas fluorescens (WCS417r) and Moringa leaf extracts against aphid infestation in wheat. The investigation was laid out in three replicates arranged under a split-plot design with two factors as a treatment, i.e., MLE and P. fluorescens mixed with the soil of wheat seedlings, but MLE was sprayed as foliar application twice, at 20- and 30-days. The aphid-infested and non-infested plants were observed to check the validity of aimed objectives. It was observed that aphid infestation mitigated the plant's novel production due to decreased plant growth, metabolism, and specific physiological pathways. On the other hand, treatments of MLE and bacteria mitigated the devastating effects of aphid infestation and improved plant growth. Plant root and shoot characters were highly improved when compared with untreated plants. Photosynthetic rates were enhanced by 24-41%, and H2O2, AsA, phenolics, proline, and MDA were reduced by 25-52% because of applied treatments. All these improvements lead to stable crop production and are highly recommendable for sustainable agricultural practices
