Resumo
ln order to evaluate the efficiency and selectivi1y of Boral (sulfentrazone),
Scepter (imazaquin) and Sencor (metribuzin) on weed control in the soybean crop, a
triai was carried out at Escola de Agronomia/ Universidade Federal de Goiás. Six
treataments were tested: 1- Boral 500 SC(I,2 1/ha); 2- Sencor 480SC(I,O 1/ha); 3- Sencor 480 SC+Scepter 150CE(0,6+o,8 1/ha); 4- Sencor 480 SC+Boral 500 se (0,75+o,70 1/ha); 5- Not weeded control; 6- Weedeq conu-ol. These treatrnents were planted as randomized blocl,s design with four replications. The soybean cultivar was MTBR-49 (Pioneira), sowing in 50 cm spacing and 20 plants/m density. There were not differences between lhe treatrnents in the first and second evaluation of Sida rhombifo/ia L., Spermacoce latifolia Aubl. and lpomoea purpurea Lam. occurrence. There were differences between treatrnents for Acanthospermum australe (Loefl.) O. Kuntze) at first evaluation (27 days after herbicides aplication and for Brachiaria decumbens Stapt.) and second evaluation ( 41 days after herbicides aplication). During the evaluations it was not ÍOIIIld fitotoxicity.
