Four experiments were conducted under field and greenhouse conditions. The first was conducted to evaluate growth, development and nutrient demands of the balloonvine plants. The second experiment was conducted under field conditions. Balloonvine seeds were sowed at several depths in order to evaluate the capacity of plant emergency. The two other experiments were carried out under greenhouse conditions to evalaute the herbicide effectiveness in controlling this species. The highest dry matter accumulation was, in decreasing order, in the stem, leaf and root. Balloonvine presented the following decreasing sequence of nutrient recruitment: N, K, Ca, Mg, S and P. The emergence of balloonvine seedlings occurred from several depths of sowing, including seeds on the soil surface up to 12 cm. The treatments 2,4-D (1005 g a.e./ha), paraquat (400 g a.i./ha), glufosinate-ammonium (300 g a.i./ha), lactofen (144 g a.i./ha), carfentrazone-ethyl (12 g a.i./ha), sulfentrazone (600 g a.i./ha) and glyphosate (960 g a.i./ha) were efficient in controlling balloonvine in the period up to four leaves. aSoja1 aVOLL, E.1 aGAZZIERO, D.
