The quest for the perfect golf course landscape is an ongoing challenge for many golf course superintendents. With the ever-increasing demand for impeccable turf quality, superintendents are constantly seeking innovative solutions to maintain healthy, dense, and visually appealing grass. One such solution is the application of Primo Maxx, a plant growth regulator (PGR) specifically designed to optimize turf growth and appearance.
Primo Maxx is a widely used PGR in the golf course industry, known for its ability to regulate turf growth, improve density, and enhance color. However, to achieve the desired results, it is essential to understand the optimal application rates for Primo Maxx on golf courses.
Understanding Primo Maxx
Before diving into the application rates, it's crucial to understand how Primo Maxx works. Primo Maxx contains the active ingredient trinexapac-ethyl, which inhibits the production of gibberellic acid, a plant hormone responsible for cell elongation. By reducing gibberellic acid production, Primo Maxx slows down turf growth, allowing for a more compact and dense sward.
Benefits of Primo Maxx on Golf Courses
Primo Maxx offers numerous benefits for golf courses, including:
- Improved turf density: By slowing down turf growth, Primo Maxx allows for a more compact and dense sward, reducing the need for frequent mowing.
- Enhanced color: Primo Maxx promotes a deeper green color, creating a visually appealing landscape.
- Reduced mowing frequency: With slower turf growth, Primo Maxx reduces the need for frequent mowing, saving time and resources.
- Increased stress tolerance: Primo Maxx helps turf recover from stress caused by drought, heat, and disease.
Primo Maxx Application Rates for Golf Courses
The optimal application rate for Primo Maxx on golf courses depends on various factors, including the type of turf, climate, and desired level of growth regulation. Here are some general guidelines for Primo Maxx application rates on golf courses:
- Cool-season grasses (e.g., Kentucky bluegrass, perennial ryegrass, and tall fescue):
- Apply 0.25-0.5 fl oz/1,000 sq ft (0.5-1.0 L/ha) every 4-6 weeks.
- Warm-season grasses (e.g., Bermudagrass, zoysiagrass, and buffalograss):
- Apply 0.5-1.0 fl oz/1,000 sq ft (1.0-2.0 L/ha) every 4-6 weeks.
- Tropical grasses (e.g., seashore paspalum and manilagrass):
- Apply 1.0-2.0 fl oz/1,000 sq ft (2.0-4.0 L/ha) every 4-6 weeks.
Factors Affecting Primo Maxx Application Rates
While the above guidelines provide a general framework for Primo Maxx application rates, several factors can influence the optimal rate for a specific golf course. These factors include:
- Turf type: Different turf types respond differently to Primo Maxx. Cool-season grasses, for example, may require lower application rates than warm-season grasses.
- Climate: Weather conditions, such as temperature, humidity, and sunlight, can impact the effectiveness of Primo Maxx. Golf courses in hot and humid climates may require higher application rates.
- Soil type: Soil type and pH can influence the absorption and efficacy of Primo Maxx. Golf courses with sandy soils, for example, may require higher application rates.
- Mowing height: The height at which the turf is mowed can impact the effectiveness of Primo Maxx. Golf courses with lower mowing heights may require higher application rates.
Best Practices for Primo Maxx Application
To ensure optimal results from Primo Maxx application, follow these best practices:
- Read the label carefully: Before applying Primo Maxx, read the label carefully to ensure you understand the recommended application rate, timing, and any necessary precautions.
- Calibrate your sprayer: Calibrate your sprayer to ensure accurate application rates and avoid over- or under-application.
- Apply during the growing season: Apply Primo Maxx during the growing season (spring-fall) for optimal results.
- Monitor turf response: Monitor the turf response to Primo Maxx application and adjust the application rate as needed.

Frequently Asked Questions
What is the optimal application rate for Primo Maxx on golf courses?
+The optimal application rate for Primo Maxx on golf courses depends on various factors, including the type of turf, climate, and desired level of growth regulation. However, general guidelines recommend applying 0.25-0.5 fl oz/1,000 sq ft (0.5-1.0 L/ha) every 4-6 weeks for cool-season grasses, and 0.5-1.0 fl oz/1,000 sq ft (1.0-2.0 L/ha) every 4-6 weeks for warm-season grasses.
How often should I apply Primo Maxx on my golf course?
+Primo Maxx should be applied every 4-6 weeks during the growing season (spring-fall) for optimal results. However, the application frequency may vary depending on factors such as turf type, climate, and desired level of growth regulation.
Can I apply Primo Maxx during the dormant season?
+No, Primo Maxx should not be applied during the dormant season (winter) as it may not provide any benefits during this period. Instead, apply Primo Maxx during the growing season (spring-fall) for optimal results.
