Roundup PowerMax is a new high load, dry free-flowing, granular glyphosate containing 72% w/w glyphosate, present as 79.2% w/w ammonium salt of glyphosate. The free-flowing, dust-free granules dissolve rapidly and completely in water with minimal foaming, allowing for improved handling. Blend of non-aggressive surfactants optimized for maximum leaf uptake without cuticle damage in shortest time, with additional benefits to operator and environmental safety. This results in unrivalled efficacy on all weeds with extremely short cultivation intervals and improved results under challenging conditions (rainfast 1 hour, hard water, dry, cold). Low drift properties of PowerMax helps farmers comply with Best Practice (sustainable use directive/water framework directive). The 10Kg bag covers the same area as a 20 litre container of a 360g/l liquid formulation, yet is less than half the weight. The design of the packs ensures that they can be emptied completely with no rinsing, and with no plastic drums packaging waste is much reduced (only 0.06kg plastic waste compared to 1.1kg from 20l can). This formulation does not require added surfactant, even at low rates, is tolerant of hard water and carries a wide range of tank mixes for maximum flexibility. Roundup Powermax is also the first granular formulation to be approved for aquatic and hard-surface area use, allowing for even greater flexibility with the product.

Approved for aquatic and plant free area use
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.

Best Practice
All agrochemicals need particular weather conditions, good application technique and target weeds in a receptive condition to achieve their very best results. Factors affecting the performance of Roundup are detailed in this section to help achieve the very best results every time they are used.Use the navigation menu on the right to go to the appropriate section.Best Practice Information:
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.
