In this study, we aimed to evaluate the impact of the herbicide Kifix® (imazapic + imazapyr) associated with Clearfield® technology of rice crops on ryegrass in succession, as well as on non-Clearfield® rice and soybean grown in rotation, in addition to the control potential of jointvetch (Aeschynomene rudis and A. denticulata) from 2016 to 2018. The experiments comprised the application of Kifix® to Clearfield® rice grown in the first experimental year, evaluating its impact (1st summer) on ryegrass grown the following winter, as well as on soybean, rice and non-Clearfield® rice grown the following summer (2nd summer). The results reported reductions in jointvetch density and infestation as Kifix® doses increased; as well as mild damage from Kifix® residues on ryegrass sown in succession to Clearfield® rice, as well as on non-Clearfield® rice and soybean in rotation to Clearfield® rice. In addition, the possibility of residue accumulation of Kifix® in the soil after repeated applications should be verified in further studies. aArroz aAzevém aErva Daninha aManejo aOryza Sativa aSoja aClearfield aImidazolinona1 aANDRES, A.1 aSILVA, L.
