“…Another example of beneficial bacteria is P. fluorescens, which has been used in agriculture as biofertilizer, biocontrol agent, and plant growth-promoter (Kiely et al, 2006). Strains of these bacteria have the ability to secrete cell wall-degrading enzymes, hydrogen cyanide, and antibiotics to suppress fungal growth, in addition to stimulating plant defense mechanisms (Zian and Aly, 2020).…”

In vitro and in vivo studies were conducted to investigate the potential of four biocontrol agents (BCAs), namely Bacillus megaterium, Pseudomonas fluorescens, Trichoderma viride, and T. harzianum, individually and in combination with sodium nitrophenolate (SN) to control marigold powdery mildew. The results showed that all treatments led to a significant inhibition in the conidial germination of Golovinomyces cichoracearum in vitro. Maximum inhibition was recorded by T. harzianum (1×109 CFU mL-1) + SN (1.5%), followed by T. viride + SN, and B. megaterium + SN at the same concentrations as follows: 83.6, 79.1, and 70.6%, respectively. While the lowest inhibition (20.4%) was recorded by P. fluorescens (1×105 CFU mL-1). In the greenhouse, all treatments applied significantly reduced the disease severity and the area under the disease progress curve (AUDPC). The combination treatments had a better disease control response than individual treatments. Similar results were achieved in the field, where disease severity reduced to 9.2 and 10.3% in plants treated with T. harzianum + SN in the first and second seasons, respectively, compared to 40.2 and 44.1% in control in both seasons. Likewise, AUDPC reduced to 274 and 315 in plants treated with T. harzianum + SN in the first and second seasons, respectively, compared to 1207 and 1340 in control in both seasons. The treatments improved growth and productivity characteristics, as well as photosynthetic pigments, total phenolic compounds (TPC), and polyphenol oxidase (PPO) activity, while significantly reducing free proline (FP). In conclusion, BCAs applied individually or in combination with SN can be used effectively to suppress powdery mildew of marigold.

“…Several modes of action for antagonistic PGPR had been reported, for instance, Pseudomonas spp. production of various antimicrobial compounds and induction of plant defense mechanisms (Alemu and Alemu, 2015;Sindhu et al, 2016;Zian and Aly, 2020). Thus, this field experiment was conducted to evaluate the influence of bio-straw and half the recommended dose of mineral fertilizer and some microbial inoculants, as well as their interactions on the growth, yield and volatile oil productions of dill plants.…”

A field experiment was conducted during the two successive seasons of 2021/2022 and 2022/2023 at the Experimental Farm, Faculty of Agriculture, Al-Azhar University, Assiut, Egypt to examine the effect of bio straw (spent mushroom compost "SMC" ) at 0, 15, 20, 25 m 3 /feddan (feddan = 4200 m 2 ) and half of the recommended doses of NPK fertilizer and microbial inoculation (Pseudomonas monteilii (MA-5) and Pseudomonas fluorescens (MP-4)) either alone or in combination, as well as, their interactions on plant growth, yield characteristics and volatile oil production of dill (Anethum graveolens L.) plants. The obtained results showed that the use of bio straw at all levels and NPKHR, expect for the low level of bio straw in some cases led to a significant increase in plant height, number of branches/plant, weight of fresh and dry herbs g/plant, number of umbels/plant, fruit yield g/plant and kg/feddan and the percentage of volatile oil and volatile oil yield ml/plant and liter/fed. The application of a high level of bio straw (25 m 3 /feddan.) gave the highest values of these traits. Apparently, application of microbial inoculation by MA-5 or MP-4 alone particularly MA-5 resulted no effect significant in the studied parameters, in most cases, in contrary, the mixture inoculation (P monteilii and P fluorescents) significantly augmented all growth attributes. The highest values of these parameters were detected when inoculation in most cases two strains together during the two seasons. The interaction effect on all studied variables was statistically significant and it is clear that the use of most combined treatments led to a significant increase in all parameters. The addition of the high rate of bio straw plus inoculation mixed of bacteria was the most effective treatment in increasing these aspects.

Roselle (Hibiscus sabdariffa L.) is one of the most crucial medicinal plants all over the world. The present study was carried out with the intention of solving some problems related to soil-borne diseases. Fusarium oxysporum is associated with wilt disease of roselle plant. The application of some microbiota i.e., a mixture of Pseudomonas fluorescens (PSR-11), Bacillus subtilis (BSR-8), Pleurotus ostreatus and mycorrhizeen® individually or in combination were investigated for controlling wilt disease, growth, and yield of roselle plant. The study was conducted in sandy textured soil under sprinkler irrigation of Ismailia Agricultural Research Station, Ismailia, Egypt. Under greenhouse conditions, all the tested bioagents reduced wilt incidence and increased the percentage of survived plants. The conglomeration of the bacterial mixture of Pseudomonas fluorescens and Bacillus subtilis, Pleurotus ostreatus and mycorrhizeen® was more effective in controlling wilt disease than using any of them individually. The application of the investigated bioagents showed a significant increase in phenol, photosynthetic pigments, and dehydrogenase contents, as well as root colonization percent. The obtained results showed the ability of B. subtilis and P. fluorescens to produce lytic enzymes such as β-1-3 glucanase, β-1-4 glucanase, chitinase and protease, in addition to their production of siderophore and HCN. The consortium of all microbiota gave the best results for growth and yield parameters of roselle plant.
