Plant diseases are still the main problem for reduction in crop yield and a threat to global food security. Additionally, excessive usage of chemical inputs such as pesticides fungicides control plant have created another serious human environmental health. In view this, application growth-promoting rhizobacteria (PGPR) controlling disease incidences has been identified an eco-friendly approach coping with security issue. this review, we different ways by which PGPRs capable reducing phytopathogenic infestations enhancing yield. PGPR suppresses diseases, both directly indirectly, mediated microbial metabolites signaling components. Microbial synthesized anti-pathogenic siderophores, antibiotics, lytic enzymes, hydrogen cyanide, several others act on phytopathogens. The indirect mechanisms infestation caused stimulation immune responses known initiation systemic resistance (ISR) is triggering elicited through pathogen-associated molecular patterns (PAMPs). ISR triggered infected region leads development acquired (SAR) throughout making resistant wide range pathogens. A number including Pseudomonas Bacillus genera proven their ability stimulate ISR. However, there some challenges large-scale acceptance pest management. Further, discuss newly formulated inoculants possessing activities suppression holistic sustaining health productivity.

Viruses pose a serious threat to the sustainable production of economically important crops around world. In past 20 years, potato virus Y (PVY) emerged as relatively new and very problem in potatoes, even though it is oldest known plant virus. Multiple strains cause various symptoms on leaves tubers resulting yield reduction poor-quality tubers. Consequently, would be interesting learn what causes systemic PVY resistance plants. Natural compounds such chitosan (CHT) phosphorus have been developed alternatives chemical pesticides manage crop diseases recent years. current study, were foliar-sprayed with assess their ability induce resistance. Compared untreated plants, findings demonstrated significant decrease disease severity accumulation plants for which CHT P applied. Every treatment includes significantly increased growth parameters, chlorophyll content, photosynthetic characteristics, osmoprotectants (glycine betaine, proline, soluble sugar), non-enzymatic antioxidants (glutathione, phenols, ascorbic acid), enzymatic (peroxidase, superoxide dismutase, lipoxygenase, glutathione reductase, catalase, β-1,3 glucanase, ascorbate peroxidase), phytohormones (gibberellic acid, indole acetic jasmonic salicylic mineral content (phosphorus, nitrogen, potassium), compared infected However, infection values, treatments showed malondialdehyde, DPPH, H2O2, O2, OH, abscisic acid levels. addition, expression levels some regulatory defense genes, including dismutase (SOD), peroxidase (APX), relative pathogenesis-related 1 basic (PR-1b), phenylalanine ammonia-lyase (PAL), found all treated PVY-infected Conclusion: Phosphorus most effective alleviating infections.

Salts of phosphonic acid (sodium or potassium phosphonate) its ester fosetyl are highly effective systemic fungicides, which not only exhibit fungistatic activities, but also stimulate the natural defence systems plants against pathogens. Since EU legislation has approved and sodium phosphonate as fungicides in 2013 2014, they no longer permitted organic agriculture. As a result, even minor contents food samples interpreted an indication fungicide treatment. A maximum level 0.01 mg/kg applies for infant nutrition. Here we present evidence from scientific literature that is compound, occurs significant amounts environment produced consumed by microorganisms within biogeochemical phosphorus cycle.

Empirical studies have shown that environmental variability in the field remains uncontrolled certain cases, with research often conducted at a limited number of agricultural sites. Direct measurements redox potential soils been reported, yet quantifying rapid changes this variable across microsites proves inaccessible situ. Existing also fail to account for identity reduced or oxidized compounds. Additionally, methodological constraints and researcher bias, particularly focusing on processes sediments, may impair interpretations anabolic reactions resulting from oxidation.Case further indicate effects nitrification, net mineralization, immobilization other nutrients remain unmeasured. As result, increased denitrification might stimulate reducing nitrogen due increasing carbon storage environments where reduction predominates.Given absence specifically exploring balance between oxidation relation nutrient availability, assessing magnitude likelihood shortcomings based prior challenging. serves as foundation understanding how significantly influence dynamics availability larger scales. Future manipulating should consider factors could disproportionately facilitate reductions before an eastward shift occurs response organic matter addition. Addressing these gaps will enhance their role stimulating sulfide responses.
