Primo MAXX®
Primo MAXX® works by blocking the production of gibberellic acid late in the cycle – which effectively limits cell elongation. The result is to shorten the distance between the shoot nodes, leading to more compact growth. whilst the vertical growth is wed, both root and lateral growth are boosted creating stronger, healthier and denser surface.
First application and timing:
Primo MAXX applications can start as soon as consistent grass growth commences. This normally occurs between mid April to mid May onwards. However, sometimes some parts of the country may not get consistent grass growth until later in the year. Consistent growth normally occurs when air and soil temperatures are consistently 8°C– 10°C or above for an extended period of time (e.g. more than five consecutive days).
Nutrient input and tank mixing:
Consistent healthy turf growth normally requires nutritional input. Most turf managers who have used Primo MAXX have also tank mixed appropriate liquid fertilizer as this eliminates the need for separate applications and can enhance the overall effect of each Primo MAXX application. Primo MAXX is physically compatible with liquid fertilizers and nutrients. For other tank Mixes, including herbicides and fungicides, consult your technical advisor before application.
The new liquid formulation Primo MAXX is easier to handle and measure than powder formulations. It rapidly and evenly disperses In the tank for easier and more effective spraying rates and thus improves the timeliness of applications.
Application advice:
Apply Primo MAXX in a water volume of 300 to 600L/Ha in a medium quality spray. Lower water volumes will increase work rates and thus improve the timeliness of applications.
Shaded areas:
Grass plants growing in shaded areas create more gibberellic acid in an attempt to reach The light – resulting in tall, etiolated growth. The application of Primo MAXX to suppress gibberellic acid production will help to minimize these effects and create a denser healthier surface.
The MAXX formulation:
Advantage:
The MAXX formulation has been specifically Designed for turf. It is:
• Very safe to turf
• Increased and enhanced product Uptake
• Very stable in the tank
• An easy to use liquid formulation
• Has fl exile application rates for all Turf surfaces
• Compatible and easily mixable with Other products
Grass species:
Primo MAXX is specific to turf management and has beneficial effects on all grass species typically sown on UK golf courses. Application rates for fast growing perennial ryegrass are higher than fine Bent, Fescue and Poa species.
Number 1 innovation in greenkeeping:
Tees
FIRST APPLICATION: Mid April – Mid May
APPLICATION FREQUENCY: Every four to five weeks.
HEIGHT OF CUT: 8–18mm
DOSE RATE: 0.8 l/ha for 8mm cut height, up to 1.6 l/ha for 18mm cut
Height.
ADDITIONAL INFORMATION:
Rate is dependent on height of cut. Tank Mix an appropriate liquid fertilizer to enhance the overall effect.
Fairways
FIRST APPLICATION: Mid April – Mid May
APPLICATION FREQUENCY: Every four to five weeks.
HEIGHT OF CUT: 10mm –18mm
DOSE RATE: 0.8 – 1.6 l/ha for fine turf fairways, up to 2.4 l/ha for Predominantly Perennial Ryegrass turf.
ADDITIONAL INFORMATION: Rate is dependent on height of cut. Tank Mix an appropriate liquid fertilizer to enhance the overall effect.
APPLICATION PROGRAMME:
The Primo MAXX programme can be commenced at any stage of The growing season, but ideally should start at the onset of spring growth and continue whilst grass is actively growing. Primo MAXX programmes will give the best results in preventing the effects of drought – by maintaining healthy grass for longer and aiding rapid recovery – if a series of treatments are made before grass comes under stress (Pre-Stress Conditioning). If grass growth stops during extended dry periods, Primo MAXXapplication periods may be extended until moisture and growth returns.
Do not apply Primo MAXX to stressed turf.
GRASS CUTTING:
Primo MAXX will slow vertical grass growth within one to two weeks of initial application. Continue to mow greens as normal.On other areas of the course mowing intervals can be extended as the cumulative benefits of the Primo MAXX programme take full effect. The first noticeable difference will be far fewer clippings to remove – up to 50% less over the season. This will significantly Increase mowing speed and reduce wear and tear on equipment. It will also reduce any financial burden under new composting waste legislation that may apply to golf courses. As Primo MAXX encourages lateral growth, to create denser ground coverage, the slower vertical grass growth will provide greater fl exibility in cutting intervals and mitigate the effects of rain disrupting the cutting schedule. Slower vertical grass growth will retain visually appealing cutting patterns for longer.
Cut height vs. Application timing:
Where course policy is for grass to be cut at a lower height, Primo MAXX applications should be more frequent, but at a lower application rate. Overall season-long application will remain broadly the same. Primo MAXX was voted the Number 1 advancement in modern greenkeeping, in a survey for Golf week’s Super NEWS. It was cited as the first PGR that could be safely and predictably used on all fine turf areas, which has proven an invaluable tool to save mowing labour and maximize turf colour and density.
