Roundup Flex is a soluble concentrate containing 480 g/l glyphosate, present as 588g/l (43.8% w/w) of the potassium salt of glyphosate.

Roundup Flex is a high load liquid with a new unique blend of surfactants with the K salt formulated to create a fully loaded Roundup. The surfactant system, whilst maintaining highly efficient activity at the leaf surface, produces a synergistic improvement in overall Roundup liquid performance. As part of our stewardship package, Roundup Flex incorporates a low drift formulation to minimize spraying of non-target areas.

Using the K salt enables Roundup Flex to be highly concentrated yet maintain low viscosity and ease of handling through a wide range of storage and application conditions.

Roundup Flex has demonstrated excellent performance in a wide range of challenging application conditions such as cool, hot and dry where reliable results can sometimes be difficult to achieve.*

Additionally, Roundup Flex boasts the widest range of tank mix partners backed by Monsanto and is approved for a wide range of uses such as on aquatic and grass free areas.
