Application of Nanotechnology in Weed Management

Abstract

Nanoherbicides being smaller in size and posessing large surface area : volume ratio are more potent than the synthetic herbicides. Micro emulsions of herbicides protects them from being degraded from various sources hence increase their residual activity. Nanocarriers help in slow and gradual release of herbicide molecules thereby increasing their efficiency. Herbicide sensors can trace the entry, movement and metabolism of herbicides in plant. Although the nanoherbicides are ecologically, socially and economically more advantageous than the synthetic herbicides still more extensive research is needed to be done in this field to have a clearer understanding about their field level response and impact on ecosystem.
