Silicon Applications to Mitigate Cold Stress on Turfgrass
Golf course superintendents face a number of challenges in maintaining healthy and thriving turfgrass, especially during cold weather conditions. Cold stress can cause a variety of problems for turfgrass, including:
- Reduced growth and development
- Increased susceptibility to pests and diseases
- Leaf discoloration and browning
- Death
Silicon (Si) is an essential nutrient that can help turfgrass withstand cold stress. Silicon applications can improve the cold tolerance of turfgrass by:
- Thickening the cell wall
- Increasing the production of antifreeze proteins
- Reducing water loss
- Regulating plant growth hormones
How Silicon Works to Mitigate Cold Stress
Silicon is a major component of the cell wall, and it plays an important role in strengthening and protecting the cell from damage. When turfgrass is exposed to cold stress, the cell wall can become weakened and susceptible to damage. Silicon applications can help to thicken the cell wall and make it more resistant to cold stress.
Silicon also helps to increase the production of antifreeze proteins. Antifreeze proteins help to lower the freezing point of water in the cell, which prevents ice crystals from forming and damaging the cell.
In addition, silicon helps to reduce water loss from turfgrass leaves and stems. This is important during cold weather conditions, as water loss can lead to dehydration and death.
Finally, silicon helps to regulate plant growth hormones. Plant growth hormones play a role in a variety of processes, including cell division, growth, and development. Silicon applications can help to regulate plant growth hormones in a way that promotes cold tolerance.
Benefits of Using Aquaritin Defend and Aquaritin 19 on Golf Courses
Aquaritin Defend and Aquaritin 19 are two silicon-based products that can be used to improve the cold tolerance of turfgrass on golf courses. Aquaritin Defend is a foliar spray that provides turfgrass with a quick and effective source of silicon. Aquaritin 19 is a soil amendment that provides turfgrass with a long-term source of silicon.
Both Aquaritin Defend and Aquaritin 19 have been shown to improve the cold tolerance of turfgrass in a number of studies. For example, a study conducted by the University of Florida found that Aquaritin Defend reduced turfgrass injury from cold stress by up to 50%.
In addition to improving cold tolerance, Aquaritin Defend and Aquaritin 19 also have a number of other benefits for turfgrass, including:
- Improved drought tolerance
- Increased heat tolerance
- Improved resistance to pests and diseases
- Reduced fertilizer and pesticide use
- Improved overall turfgrass health and resilience
