“…Understanding herbicide efficacy on weed species over time is important because knowledge about this characteristic helps when choosing herbicide rates to obtain the desired residual effect, in case of chemical management in pre-emergence (Carvalho et al, 2005) -especially in sugarcane, given that it is the main weed management tactic used. In pre-planting operations, pre-emergent herbicides can also be mixed with postemergence herbicides, aiming residual weed control.…”

“…ha -1 ) which provides 50% of percentage control or weed dry matter reduction, respectively (Christoffoleti, 2002;Carvalho et al, 2009). Although one parameter of the logistic model (b) is a LD 50 or GR 50 estimate, it also underwent mathematical calculation as did LD 80 and GR 80 estimates through the inverse equation based on the discussion proposed by Carvalho et al (2005).…”
