摘 要：
The paper aims to develop the application method of sodium monosulfuron-ester.[Methods] A series of weed control tests were conducted and the field efficacy was studied of sodium monosulfuron-ester·MCPA-Na 25% AS in winter wheat fields.[Results] The results showed that: sodium monosulfuron-ester·MCPA-Na 25% AS at 225-562.5 g a.i./ha has very good efficacy on Descurainia sophia,Capsella bursa-pastoris,Silene conoidea and other annual broadleaf weeds,after 45 days of application,its inhibiting effect on weeds is above 90%(in numbers) and above 95%(in fresh weight).[Conclusions] Sodium monosulfuron-ester·MCPA-Na 25% AS can effectively control the weeds.At the recommended rate of application it is safe on wheat.
