Effect of 10% tripyrasulfone·anilofos in the control of weeds in rice fields
In response to the problems of large populations,rapid variation,high resistance,and difficult control of weeds in rice fields,an experiment was conducted on the weed control effect of tripyrasulfone·anilofos herbicide on transplanted rice and direct seeding rice fields.The experimental results indicate that,whether in transplanting rice fields or direct seeding rice fields,the application amount of 10% tripyrasulfone·anilofos dispersible oil suspension(OD)active ingredient is 375-600 g·hm-2 after the transplanted rice or the direct seeded rice returns to green,weeds such as barnyard grass are treated by spraying at 2-3 leaf stages.It has good control effect on weeds such as barnyard grass and millet in rice fields.The control effect of the main weeds in the field is 97.4% or above,and the rice yield increases by 42.10% or above,which is safe for rice production.Therefore,10% tripyrasulfone·anilofos OD can be used to control weeds such as barnyard grass and millet in rice fields.
