Rice (Oryza sativa L.) is the principal food for more than 50% people and contributes about one-fifth to the total calories consumption of the world. High yielding cultivars have been introduced in recent years, leading to an increase in rice output; yet, because to inadequate weed control, their maximal yield potential has not been completely realised. One of the most crucial elements in increasing crop productivity is effective weed management. In transplanted rice, unchecked weed development reduces grain production by approximately 30-36%. When it comes to enough nutrients, moisture, light, and growing area, weeds compete with one another. Rice requires effective weed control in order to reach its full output potential. Chemical, mechanical, cultural, and manual techniques could all be used to eradicate these weeds.
Although quite prevalent, cultural, manual, and mechanical approaches are expensive. When used alone, herbicides can be affordable, but they may also limit the development of resistance, change the flora of weeds, and other issues. Thus, to manage the diverse weed ecology in transplanted rice, high efficiency herbicides must currently be used in conjunction with broad spectrum types. Additionally, the combination of herbicides saves time, lowers cultivation costs, and expands the spectrum of weed control.
