Microcosms, each consisting of 2L natural surface seawater maintained in 2.3-L glass bottles, were immersed at a depth of 6m. The renewal of 10% of microcosm volumes was carried out every other day. Phytoplankton-containing seawater was used for renewal (previously filtered through 25-, 50- or 200-μm cut-off). Phytoplankton community pigment analysis (by HPLC) and flow cytometry analysis were p...
Ryegrass and turnip are weeds that cause high yield losses when infesting barley, thus requiring adequate management. In this context, the aim of study was to evaluate selectivity different herbicide treatments weed control in barley crop, cultivar BRS Cauê. Two field experiments were conducted randomized blocks, with four replications. The used were: pendimethalin (800 g·ha-1), sulfentrazone +...
