Bacillus subtilis DZSY21 isolated from the leaves of Eucommia ulmoides oliv. was labeled by antibiotic marker and found to effectively colonize the leaves of maize plant. Agar diffusion assays and biocontrol effect experiments showed that strain DZSY21 and its lipopeptides had antagonistic activity against Bipolaris maydis, as well as high biocontrol effects on southern corn leaf blight caused ...

A novel method of management maize pathogens in vitro and vivo using newly synthesized copper nanoparticles (CuNPs) has been documented this study. CuNPs have CuSO4 as a precursor, NaBH4 ascorbic acid reducing agent, polyethylene glycol 8000 (PEG-8000) stabilizing agent. Characterization Transmission Electron Microscope (TEM) confirmed the nanoparticles’ size range 35–70 nm. Fourier transform i...

Antimicrobial peptides (So-D1-7) were isolated from a crude cell wall preparation from spinach leaves (Spinacia oleracea cv. Matador) and, judged from their amino acid sequences, six of them (So-D2-7) represented a novel structural subfamily of plant defensins (group IV). Group-IV defensins were also functionally distinct from those of groups I-III. They were active at concentrations < 20 micro...

A method using LC-ESI-IT-TOF/MS and LC/UV-ELSD was established to qualitatively analyze triterpene saponins obtained from the tea seed pomace (Camellia oleifera Abel). In addition, the quantitative analysis of oleiferasaponin A1 using LC/UV was developed. The purified total saponins did not exhibit any inhibitory effects at concentrations ranging from 0.1 to 10 mg/mL against the tested bacteria...

Southern leaf blight of maize (Bipolaris maydis) is one the major disease in many countries including India. An experiment was conducted for two consecutive years during rabi 2019 and 2020 to develop an integrated management southern using fungicides, botanicals bioagents under natural field conditions. Propiconazole found be best showed 100% mycelial growth inhibition vitro at 0.1%. Among bota...
