Bitter Apple Extract Yields Silver, Zinc, and Copper Oxide Nanoparticles Effective Against Maize Weevils and Microbial Contamination

**FOR IMMEDIATE RELEASE**

A recent study details the successful green synthesis of silver oxide, zinc oxide, and copper oxide nanoparticles using Solanum incanum, a plant commonly known as the bitter apple. Researchers investigated the efficacy of these nanoparticles in controlling maize weevils (Sitophilus zeamais) and postharvest microbial contamination, presenting a potential eco-friendly alternative to traditional pest control methods.

The study outlined a method where Solanum incanum plant extract facilitated the synthesis of the nanoparticles. Following synthesis, the nanoparticles were characterized to confirm their composition and properties. Subsequent experiments then assessed the nanoparticles’ effectiveness against maize weevils, a significant postharvest pest, and their ability to inhibit microbial growth, which often leads to spoilage of stored grains. The findings suggest that these nanoparticles could offer a dual benefit by protecting crops from both insect infestation and microbial degradation.
