Attraxor® has been shown to effectively regulate growth of managed amenity turf. The active substance inhibits the giberrelic acid pathway which results in a reduction of turf height and turf biomass. Root growth is promoted through the use of Attraxor® whilst turf colour and quality are maintained.
Prohexadione, the active substance in Attraxor® is activated in the tank by the addition of water; therefore growth regulation occurs rapidly following application of the product.
Instructions for Use
Where to use: For use on managed amenity turf.
When to use:
- Apply when grass is growing consistently and air temperatures are between 7°C — 21°C.
- Initial application can be made once there have been 450 growth degree days in the year based on the zero GDD model.
- Subsequent applications can be made every 21 days from this point.

How to use*:
- Add 3/4 of the required water to the spray tank.
- Before adding any other products; remove top hat filter and pour Attraxor® directly into the tank whilst agitating the water.
- Agitate well to ensure Attraxor® is fully dissolved then add remaining water through top hat filter.
- Apply one hour after mowing in slow drying conditions.
Additional information:
- Use the lowest stated water volumes when mixing with hard water.
- Ideal pH of spray solution is 4.5 - 5.5.
- Add Attraxor into the spray water before any other products
- Having removed the top hat filter, add Attraxor directly into t a spray tank containing 3/4 of the final spray volume and agitate until dissolved
- Attraxor should be applied alongside 2.5 kg/ha supplementary nitrogen.
- Do not mix with fertilisers containing calcium, magnesium or boron.
- Replace lid immediately as Attraxor® granules will rapidly absorb water from the atmosphere.
- Do not apply when turf is stressed or in direct sunshine.
- Do not irrigate for at least four hours post application.
* Application rates for Attraxor® are dependent on turf height and presence/absence of Poa annua. See tables below for more detailed application rate information.

Tank Mix Companions
Option 1
Mix with ammonium sulphate in the tank to:
- Keep the spray solution within the optimal range of pH 4.5 - 5
- Provide supplementary nitrogen at a rate of 2.5 kg N/Ha
Option 2
Where nitrogen application is not the desirable mix, utilise a pH indicator followed by a turf pigment.
Suitable products:
- Water conditioner
- Green Lawnger Pro HC pigment at 1.2 L/ha
Active Substances - Prohexadione
Bio-Chemical Mode of Action: Prohexadione reduces plant growth by inhibiting the synthesis of gibberellins.
Mobility: Prohexadione has xylem mobile activity which means that it is absorbed through the leaves then moves upwards through the plant within the xylem (water conducting tissues).
Application Timing: Plant growth regulators should be applied when the plant is actively growing. It is recommended that prohexadione applications commence after 450 growth degree days in the year. Subsequent applications can take place every 21 days.
I start using Attraxor® on my greens at the end of April or beginning of May. As a result we detect up to a 50% reduction in mowing intervals

We use an Attraxor® programme all season across our natural grass pitches, both at the training ground and stadium. From this we see a 50% reduction in mowing frequency and clipping volumes, which provides considerable time and cost savings
