Changes on floristic composition of Flooding Pampa rangeland by the use of glyphosate

摘要：

To increase winter forage production of native rangelands of Flooding Pampa, a technique based on spraying glyphosate herbicide in late summer has been widespread during the last decade in this region.Glyphosate application eliminates green vegetation growing in late summer, improving germination and establishment of cool season (C3 ) annual grasses, that enhaces winter forage and meat production.We postulate that this technique would negatively affects plants that vegetate during summer, such as perennial grasses and legumes, decreasing floristic diversity and deteriorating the rangeland.
