Residual herbicide adjuvant Backrow Max helps get on top of yield-robbing weeds
Tired of fighting grassweeds year-after-year?
As increasingly suboptimal weather conditions continue to weaken residual herbicide performance and risk crop and groundwater safety, keeping problem weeds at bay can feel like a never-ending battle. Adding a proven adjuvant to your tank mix is the #1 thing you can do to boost the efficacy of your herbicide and protect your crops from the threat of weeds.
Backrow Max is a new specialist activator adjuvant designed to power residual herbicide performance in the toughest of weather and application conditions, helping to take down yield-robbing weeds once and for all.
Take herbicide performance to the max
Backrow Max is based on the UK’s leading residual herbicide adjuvant Backrow:
- Same tried and trusted benefits
- Cleaner label – no hazard statements
- More active per litre – at least as effective
- Strongest herbicide retention in wet soils – best on test

Why you can count on Backrow Max
Optimises herbicide coverage & deposition across the soil
Backrow Max:
- significantly reduces the number of fine spray droplets smaller than 100 microns which are the most susceptible to drift.
- increases the number of droplets in the optimum size range for improved deposition and optimum spray coverage of the soil.
Even spray coverage across the soil surface is vital for effective residual herbicide performance.
But, pre-emergence applications are prone to drift and this puts deposition and effective spray coverage at risk.
Adding Backrow Max creates the perfect size spray droplets for pre- and peri-emergence herbicides to work at their best.
Trials show a combination of drift reducing nozzles and Backrow Max offers the best approach for the optimal targeting of residual herbicide applications to block germinating weeds.
Spray application tests: Backrow Max reduced the number of drift prone Liberator droplets by 35%
Lowers dependency on rainfall for activation & uptake
Likened to rain in a can, Backrow Max increases moisture retention in the top 5cm of the soil, reducing dependency on rainfall for herbicide activation and uptake into weeds.
Trials in The Netherlands have shown that Backrow Max can increase moisture retention by as much as 30%.
All residual herbicides require soil moisture for activation and uptake in to weeds.
Typically, some rainfall following application will be required to ”activate” herbicide movement from the soil surface to the weed germination zone for uptake to occur.
With increasingly dry conditions at drilling, Backrow Max gives your herbicide the best possible chance of performing to its potential.
Research and trials have shown that Backrow Max improves the performance of residual herbicides in dry soils and can benefit weed control by as much as 20%.
Creates a stronger barrier to emerging weeds in wet soils
Backrow Max retains significantly more herbicide in the top 5cm of the soil compared to herbicides applied alone.
Adding Backrow Max ensures a longer and more concentrated presence of the herbicide in the weed germination zone in wet soils, creating a stronger barrier to emerging weeds.
Pre-emergence herbicides and their active substances often require additional support from an effective adjuvant to keep them in the weed germination zone (the top 5cm of the soil) in wet soils.
With excessive rainfall, even herbicides with low mobility such as pendimethalin, can be lost, particularly in light soils, leading to poor weed control.
Research conducted by the Institute of Soil Science and Plant Cultivation in Poland in 2021 and 2022 showed:
- Adjuvants vary greatly in their influence on herbicide retention in wet soils
- Backrow Max was the top performing adjuvant on test
- Backrow Max held significantly more herbicide in the top 5cm of the soil compared to herbicides applied alone
The addition of Backrow Max ensures superior herbicide performance in wet soils, for the ultimate weed free start.
Reduces chemical leaching
Backrow Max increases herbicide retention in the upper soil profile, reducing leaching to crop seed and groundwater lower down.
Research in the Netherlands has shown that Backrow Max can reduce chemical leaching by as much 60%.
Chemical leaching from the top 5cm of the soil can become problematic with the stacking of residual herbicides late in the autumn, when soils become saturated with prolonged spells of heavy rain.
Herbicides with high mobility pose the biggest threat to crops and groundwater, particularly in light soils.
Backrow Max adds valuable protection to crop and groundwater safety by minimising chemical loss from the weed zone.
