Weeds and their Management under Changing Climate: A Review

Abstract

World is now facing a greater menace of climate change and this has a long term impact on agriculture system. Weeds are one of the major factors that hold back the crops from attaining potential yield. The changing climate can have an effect on weed diversity, establishment and management. The response of weeds to altering climate mainly leans on the physiological characteristics of the weed and how productively it can respond to the immediate climatic condition. Due to high plasticity of weeds, management of these unwanted plants become difficult. This has significant repercussions on weed control practices, especially herbicide performance and effectiveness. Therefore, an integrated approach of weed management is adopted to reduce the impact of climate change on crop-weed interaction.
