Abstract: In order to identify the effective agent to prevent and remove broadleaf weeds in rice transplanting field, the control effect and safety of 3% diflufenican granules on broadleaf weeds in rice transplanting field were studied. One day before rice transplanting, the field was evenly distributed with the herbicide, and the growth of rice and the control effect of broadleaf weeds were investigated regularly after spraying herbicide 20, 40 days. The results showed that 3% diflufenican granules could effectively prevent and eliminate annual broadleaf weeds such as Ludwigia prostrata, Monochoria vaginalis, Eclipta prostrata. After application, the inhibition effect of 3% diflufenican granules on the growth of weeds was obvious, and it was safe for rice. It was recommended to apply 3% diflufenican granules with the dosage of 135~225 g(a.i)/hm2.
