Eco-friendly weed management options for organic farming: A review

S Sanbagavalli, Jeeva M and E Somasundaram
Weeds are the major biotic factor which cause significant reduction in crop yield. Weeds will compete with crop for nutrients, light, water etc. In accordance with weeds in organic production system, weeds as one of their most troublesome, time consuming and costly production problems. Application of high dose of inorganic herbicide led to more toxic accumulation besides causing degradation to the soil health, pollution of ground water table and extinct of natural enemies. Weeds are conventionally controlled by herbicides which led to herbicide persistence and resistance and shift of weed flora by alien weeds. So, organic weed management is much needed to exert higher crop productivity. In organic production weeds are be managed by use of clean seeds, composted manures and timely removal of weeds by cultural, physical, mechanical, thermal and biological means during critical crop-weed competition.
