Using Ryder to safeguard turf through summer heat

These grasses start to struggle once temperatures pass 24°C, with severe decline possible beyond 35°C. In these conditions, every available strategy must be considered, one such asset is Ryder, a turf pigment proven to offer benefits in extreme heat.

What makes Ryder effective?

Ryder is a turf pigment developed to enhance colour, improve visual appeal, and crucially, increase tolerance to environmental stress. While its immediate effect is aesthetic, the science behind Ryder provides much more. Intense sunlight and UV exposure can hasten turf decline, especially when other stressors such as drought or nutrient deficiencies are present.

By acting as a light-modulating barrier, Ryder absorbs and reflects excess radiation. This helps the turf in several key ways:

• Maintains steady photosynthetic activity
• Minimises oxidative stress on foliage
• Preserves chlorophyll, supporting sustained colour
• Aids recovery following heat stress events

Understanding heat stress in turf

Cool-season turf functions best between 15°C and 24°C. Once temperatures exceed that range, photosynthetic rates drop while respiration increases, tipping the balance so the plant consumes more energy than it produces.

Above 35°C, even intensively managed turf may start to break down. Enzymatic processes are disrupted, cell membranes become unstable, and visual symptoms can develop rapidly, especially if compounded by drought or other pressures.

How Ryder supports turf under pressure

While Ryder doesn’t eliminate heat stress, it serves as a proactive aid to extend turf resilience during tough spells. Applying it ahead of heatwaves or prolonged warm periods primes the plant to handle the added burden.

Best practices include:

• Application prior to forecasted high temperatures
• Pairing with Primo Maxx II to control growth and ease metabolic demand
• Including Hicure or a compatible biostimulant to bolster post-stress recovery

Ryder also offers value in maintaining presentation, helping to mask the early signs of stress so surface quality remains visually consistent.

Making the most of Ryder

Ryder is suitable for use throughout summer, with a few important caveats:

• Avoid spraying during peak midday heat
• Follow the label instructions precisely, especially when tank-mixing with other products
• Ensure adequate soil moisture, Ryder is most effective when turf hydration is stable
• Adjust reapplication intervals based on mowing frequency, rainfall, and visual cues

Final thoughts

High temperatures place significant strain on turf systems, even those carefully managed. Ryder delivers a tactical advantage by helping turf maintain function and appearance through heat stress.

Incorporate Ryder as part of a broader strategy, including moisture management, nutritional support, and informed decision-making. When used correctly, Ryder not only enhances the turf surface but safeguards the standards and investments made during the most demanding season of the year.
