Synthesis, Characterization of Pendimethalin Encapsulated PVA Nanofiber and Its Impact on Blackgram

Abstract

Nanotechnology operates at the nanoscale, offering precise manipulation and enhancing materials, applications, and performance across various domains. It holds promise in addressing weed-related losses, with nanofibers emerging as a noteworthy option among diverse nano-formulations. The research conducted at Centre for Agricultural Nanotechnology, TNAU, Coimbatore focuses on crafting pendimethalin-loaded PVA nanofibers. The nanofiber structure and successful pendimethalin integration were examined using SEM and FTIR analyses. Coating black gram seeds with pendimethalin-infused PVA nanofibers were assessed for their impact on growth and germination. SEM data indicated a rise in fibre diameter post-loading in PVA nanofiber-coated seeds (from 118.3 nm to 332.9 nm) and in pendimethalin-loaded PVA nanofiber coated seeds (from 339.8 nm to 664.5 nm). FTIR results validated pendimethalin presence within PVA nanofibers. Germination test demonstrated that herbicide-loaded nanofiber coatings didn't hinder germination or growth. In summary, synthesizing herbicide-loaded nanofibers and their seed coating presents a pioneering concept, warranting further exploration for its potential in weed seed germination and control.
