MIXTURE AND METHOD FOR CONTROLLING UNDESIRED VEGETATION

              FIELD OF THE DISCLOSURE
This disclosure relates to a mixture of sulfometuron-methyl, chlorimuron-ethyl and

glyphosate, and a method for using this mixture for controlling certain undesired vegetation

5

such as Brachiaria decumbens (surinam grass) and Ipomoea grandiflora (Corda-de-viola).

           BACKGROUND OF THE DISCLOSURE
The control of undesired vegetation is extremely important in achieving healthy crop

plants such as soybean (Glycine Max, i.e. STS soybean) and sunflower (Helianthus annuus,


i.e. ALS-tolerant sunflower). Selective control of vegetation is desired for the following

10 weed species from Brazil selected from Caruru-roxo (Amaranthus hybridus), Capim- carrapicho (Cenchrus echinatus), Nabiça (Raphanus raphanistrum), Buva (Conyza bonariensis), Capim-colchão (Digitaria horizontalis), Corda-de-viola (Ipomoea grandifolia), Amendoim-bravo (Euphorbia heterophylla), Mata-pasto (Sida rhombifolia), Trapoeraba (Commelina benghalensis), Poaia-branca (Richardia brasiliensis), Picão-branco (Galinsoga

parviflora), Azevém (Lolium multiflorum), Buva (Conyza bonariensis) and Picão-preto; and the following weed species from Argentina selected from Amor seco(Bidens pilosa), Angallis(Anagallis arvensis), Altamisa colorada (Descurainia argentina), Apio cimarrón (Ammi majus), Bolsa de pastor (Capsella bursa pastoris), Caapiquí (Stelaria media), Cardo (Carduus acanthoides), Cerraja (Sonchus sp.), Flor de la noche (Oenothera indecora),

Manzanilla(Anthemis cotula), Marcela (Gnaphalium cheirantifolium), Mastuerzo (Coronopus didymus), Parietaria/ocucha (Parietaria debilis), Ortiga (Urtica urens), Ortiga mansa(Lamium amplexicaule), Peludilla (Gamochaeta spicata), Pensamiento silvestre (Viola arvensis), Perejilillo (Bowlesia incana), Rama negra (Conyza sp.), Quínoa (Chenopodium album), Verdolaga (Portulaca oleracea), Yuyo colorado (Amaranthus

quitensis), Gramíneas Anuales, Pasto Cuaresma (Digitaria sanguinalis), Brachiaria (Brachiaria plantaginea), Capín (Echinochloa crus galli; E. colonum), Eleusine (Eleusine indica), Roseta (Cenchrus pausiflorus) and Maíz guacho (Zea mays) are particularly undesirable where it is growing in soybean (Glycine Max, i.e. STS soybean) or sunflower (Helianthus annuus, i.e. ALS-tolerant sunflower). Undesired vegetation from the genus

30

Brachiaria and Ipomoea is considered undesirable vegetation when growing in soybean (Glycine Max, i.e. STS soybean) or sunflower (Helianthus annuus, i.e. ALS-tolerant sunflower) fields because of the yield reduction that they cause. The need continues for new herbicide treatments that are more effective, less costly, less toxic and environmentally safer.
