Summary: Silver nanoparticles (AgNPs) were synthesized using Trigonella foenum-graceum L. leaf extract, which contains phytochemicals that play important roles in the reduction of silver ions to AgNPs. The synthesized AgNPs had spherical shapes with a diameter of 4-22 nm. The antimicrobial and antioxidant activities of AgNPs and leaf extract were evaluated, and AgNPs showed significant efficacy in both aspects. These findings suggest that AgNPs could be utilized in biomedical applications and drug delivery systems.

Summary: This study presents the phytosynthesis of silver nanoparticles using Leonurus cardiaca L. extracts for the first time. The influence of extraction method and extract concentration on nanoparticle characteristics was investigated using analytical methods. Experimental data showed that lower extract concentration and microwave-assisted extraction resulted in smaller nanoparticles. The phytosynthesis process enhanced antioxidant and antimicrobial properties compared to the parent extracts. This research is important for obtaining nanoparticles with enhanced properties and controlled morphologies, as well as for understanding the phytosynthesis of metallic nanoparticles using low extract concentrations.

Summary: The efficacy of two entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae, for endophytic colonization on maize plants and their impact on the survival, development, and fecundity of the fall armyworm, Spodoptera frugiperda, were evaluated. Both fungi effectively colonized the maize plants and negatively impacted the development and fecundity of the fall armyworm. These findings suggest that entomopathogenic fungi can be used to control the fall armyworm by endophytic colonization of maize plants.
