Weeds are a big problem for rice farmers in India when they plant rice seeds directly in dry soil. These weeds grow at the same time as the rice, making it hard to get rid of them. This can reduce rice yields by a lot. A study looked at different ways to control weeds in this type of rice farming. They found that using a chemical called pendimethalin can help control weeds and increase rice productivity and profits, especially in places where there is not enough labor to remove weeds by hand. This is important for farmers in India who grow a lot of rice this way.
