Roundup Flex

Rainfast from 1 hour

• High-spec weather-fast formulation

• More opportunity to take advantage of weather windows

• Ensures the maximum amount of glyphosate gets to the roots

Superior performance in challenging conditions

• Improved reliability, even in hot and dry or cool and dry weather conditions

• Helps make the most out of weather windows, especially pre-harvest

Less risk of drift

• Reduces risk of damage to neighbouring crops and hedges

• Reduces of risk of bystander exposure

• Reduces risk of direct contamination of surface water

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.

The Roundup Brand was born in 1974. Since then products based on glyphosate have become the most widely used herbicides in the world. The benign nature of the molecule to operators and the environment combined with excellence in weed control make it first choice for non-selective weed control.

Mode of Action

Once applied to the leaf uptake occurs within 1-6 hours and glyphosate moves through the phloem both downwards and upwards within 5 days. It tends to accumulate in the growing points, then evens up throughout the plant, leading to a gradual loss of green colour followed by death between one and four weeks later.

Glyphosate works at a single specific site in the Shikimic acid pathway to inhibit the production of the amino-acids phenylalanine, tryptophan and tyrosine. Amino- acids are the building blocks of protein molecules and once the biochemical pathway is blocked the synthesis of proteins is interrupted and the plant effectively starves to death. The process is temperature related and explains why treated plants take some time to die.

For more detailed information about the glyphosate mode of action see the glyphosate infomation portal http://www.glyphosate.eu/glyphosate-basics/how-glyphosate-works

Environmentally Friendly

This metabolic pathway is present only in green plants. Higher forms of life like mammals, birds, fish and insects are dependent on plant sources to obtain these three amino-acids in their food and neither absorb nor metabolise glyphosate. This is the reason Roundup has such environmentally friendly characteristics.

No other class of commercial herbicide is known to target this site (HRAC group G).

Glyphosate Formulations

All glyphosate products are not same. While they all contain the active ingredient, glyphosate, the formulation type in which the glyphosate is carried plays a major role in performance.

Our formulation chemists have worked continually since the launch of Roundup to bring out new formualtions with improved weed control, leass restrictive conditions of use and better safety profiles under COSHH.

Modern formulations of Roundup are highly active and provide the highest levels of uptake and translocation leading to improved speed, rain fastness and efficacy.

Cross compliance requirements apply to anyone who receives direct payments under Common Agricultural Policy (CAP) support schemes or receives payments under certain Rural Development schemes. Compliance with both European legal requirements, known as Statutory Management Requirements (SMRs) and with domestic legal requirements requiring land be kept in Good Agricultural and Environmental Condition (GAEC) is required and any breach may result in reductions of EU payments

Information on situations where Roundup can be used as part of Stewardship Schemes is contained in this section.
