“…Em razão da importância do glifosato para a agricultura mundial, estudos têm sido conduzidos com o objetivo de avaliar a contribuição de diferentes variáveis em sua efi cácia, das quais se podem destacar: dose (Jordan et al, 1997), volume de calda (O'Sullivan et al, 1981;Ramsdale et al, 2003), qualidade da água (Thelen et al, 1995;Ramos & Durigan, 1998;Gauvrit, 2003), estádio fenológico das plantas daninhas (Durigan, 1992;Jordan et al, 1997) e atividade de adjuvantes (O'Sullivan et al, 1981;Pratt et al, 2003;Nurse et al, 2008).…”

“…), 2,4-D (Sexsmith 1953), picloram (Turner and Loader 1972;Wilson and Nishimoto 1975), dichlorprop (Turner and Loader 1984) and glyphosate (Blair 1975;Suwunnamek and Parker 1975;Loader 1975, 1980;O'Sullivan et al 1981). Enhancement of a non-water-soluble herbicide with ammonium sulphate was first reported for sethoxydim (Chow and MacGregor 1983 For the other species, the leaf-stage at the time of treatment was 4, 3, 4 (canola); 3, 3, 4 (green foxtail) and 3, 4, 3 (wild oat) for 1984, 1985 and 1986, respectively.…”

“…En un estudio realizado en cámara de crecimiento con cebada, O'Sullivan et al (1981) encontraron que al incrementar los volúmenes de aplicación de 110 a 550 L ha -1 , se redujo la efectividad del glifosato a las dosis de 0.14 y 0.28 kg ha -1 , en comparación con las dosis de 0.56 y 0.84 kg ha -1 . Sin embargo, en el cultivo de caña de azúcar, Rodrigues et al (2011) encontraron que el volumen asperjado no tuvo efecto en el grado de control de Digitaria insularis (L.) Fedde por este herbicida.…”

“…In a study conducted in a growth chamber with barley, O'Sullivan et al (1981) found that increasing the volume of application from 110 to 550 L ha -1 , the effectiveness of glyphosate at rates of 0.14 and 0.28 kg ha -1 was reduced, in comparison to doses of 0.56 and 0.84 kg ha -1 . However, in sugar cane crops, Rodrigues et al (2011) found that the sprayed volume had no effect on the degree of control of Digitaria insularis (L.) Fedde by this herbicide.…”
