In South Asian countries, the lucrative production of peaches has been seriously threatened by an assortment biotic stresses especially nematodes. This situation compromises achievement sustainable development goals (SDGs) related to food security and zero hunger. Recently under changing climate, root-knot nematodes genus Meloidogyne have emerged as most damaging phytopathogenic nematodes, while efficacy chemical control remained limited. Therefore, a study was executed assess four biocontrol agents including Pochonia chlamydosporia, Purpureocillum lilacinum, Trichoderma harzianum, T. viride (at concentrations 2.5 × 103, 5 7.5 1 104) along with nematicide Rugby treatment against javanica on peach. The response variables included nematode infestations in terms number galls, egg masses, reproductive factors. P. lilacinus harzianum (1 104 concentration) reduced galls 18% 16%, respectively, than control. All exhibited their effectiveness significantly reducing eggs per mass, factors, these statistically at par each other. proved that application holds potential for controlling might be developed potent strategy replace or least reduce use traditional chemicals avoiding environmental pollution contamination.

Cyanobacteria represent a rich resource of wide array unique bioactive compounds that are proving to be potent sources anticancer drugs. Selenium nanoparticles (SeNPs) have shown an increasing potential as major therapeutic platforms and led the production higher levels ROS can present desirable properties. Chitosan-SeNPs also presented antitumor properties against hepatic cancer cell lines, especially Cht-NP (Chitosan-NPs), promoting generation mitochondria dysfunction. It is proposed magnetic fields add new dimensions nanoparticle applications. Hence, in this study, biosynthesis SeNPs using Alborzia kermanshahica chitosan (CS) stabilizers has been developed. The synthesis was performed at different cyanobacterial cultivation conditions, including control (without field) 30 mT 60 mT. were characterized by uv-visible spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), Dynamic light scattering (DLS), zeta potential, TEM. In addition, antibacterial activity, inhibition bacterial growth, minimum inhibitory concentration (MIC), bactericidal (MBC), well antifungal activity cytotoxicity SeNPs, performed. results spectrometry, DLS, showed had highest value regarding adsorption, size, stabilization compared control. FTIR consistent spectra, but increased intensity peaks indicates increase bond number after exposure zone diameter synthesized Staphylococcus aureus more sensitive produced under Se-NPs cultured field exhibit antimicrobial properties, making them promising natural agent for use pharmaceutical biomedical industries.
