In agriculture, soil-borne fungal pathogens, especially Fusarium oxysporum strains, are posing a serious threat to efforts achieve global food security. the search for safer agrochemicals, silica nanoparticles (SiO2NPs) have recently been proposed as new tool alleviate pathogen damage including wilt. Hollow mesoporous (HMSNs), unique class of SiO2NPs, widely accepted desired pesticide carrier. However, their role in enhancing disease resistance and specific mechanism remain unknown. this study, three sizes HMSNs (19, 96 406 nm HMSNs–19, HMSNs–96 HMSNs–406, respectively) were synthesized characterized determine effects on seed germination, seedling growth, f. sp. phaseolus (FOP) suppression cowpea roots by foliar spray using phenotypes, fresh biomass progression indicators. The results revealed that exhibited no adverse impacts germination tended improve plant growth. Also, they exert FOP with size- concentration-dependent manner. HMSNs–406 possessed best control effect at concentration 1000 mg/L showing an upto 40.00% decline severity. Si(OH)4 was also effective lower 100 mg/L, whereas its higher concentrations obviously control, Moreover, we conformed posed wilt activating SA (salicylic acid)-dependent SAR (systemic acquired resistance) responses rather than directly suppressing FOP. A level content elevated expression maker genes PR-1 PR-5 treated provided substantial evidences mode action. Other resistance-related genes, well defense-responsive enzymes, involved HMSNs-activated pathway. Overall, first time, our extended potent elicitor serve versatile alternative protection low cost, highly efficiency sustainability.
