Weed Management Under Variable Crops grown in Diverse Environments

Abstract

Weeds are a significant problem for the efficiency and profitability of crop production systems worldwide. Since the introduction of herbicide-resistant crops, the use of herbicides as a weed control method has risen steeply because they are among the most effective among available methods. Weeds that are resistant to herbicides and other negative consequences for human and environmental health are a direct result of overusing herbicides. Sustainable weed management in major crop production systems can be aided by crop diversification. It provides a framework for integrating scientific discoveries and ecological understanding into weed management strategies for the long term. In order to increase the reliability and efficiency of ecosystem services, "diversified cropping" refers to the deliberate use of functional biodiversity at the temporal and/or spatial levels. Reduced weed density can be achieved through crop diversification's inhibitory effect on weed seed germination and weed growth. Furthermore, diversified farming systems are more resistant to climate change and produce higher crop yields than monoculture systems. The adoption of a diversified cropping system, however, faces a number of obstacles. These include, but are not limited to, changes in technology, government policies, farm-level decisions, climate, and market conditions. This review looks at the ways in which crop diversification helps with weed management, the difficulties that come along with it, and the prospects for weed control in light of the diversification idea.
