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.
