Turf Mechanic - Killing Weeds In Fine Fescue Grass (Shade) Using CRAZY Expensive Pylex
The speaker explains the difficulties of managing fine fescue grass, particularly in shaded areas where it thrives but is susceptible to damage from common herbicides. Fine fescue cannot tolerate pre-emergent herbicides or certain post-emergent ones like tenacity during seeding. The speaker highlights the problem of unwanted grassy weeds that grow alongside fine fescue, especially in shaded areas or on slopes where fescue is planted. To address this, the speaker uses Pylex, a highly effective but expensive herbicide that targets warm-season grasses without harming cool-season grasses like fine fescue. Pylex requires only a minimal amount per application, making it cost-effective for small areas. The speaker demonstrates the application process, emphasizing the importance of using a surfactant like methylated seed oil to enhance the herbicide's effectiveness. After 13 days, the speaker observes the bleaching effect on unwanted grasses, indicating the herbicide's success. The video concludes with advice on using Pylex in transition zones or areas with mixed grass types to maintain a healthy fescue lawn.
Key Points:
- Fine fescue is sensitive to many herbicides; avoid using pre-emergents and tenacity during seeding.
- Pylex is an effective herbicide for controlling warm-season grasses in fine fescue lawns, though it's expensive.
- Use minimal amounts of Pylex (1 ml per 1,000 sq ft) with a surfactant like methylated seed oil for best results.
- Observe bleaching in unwanted grasses within 10-20 days after application, indicating successful treatment.
- Pylex is ideal for transition zones or areas with mixed grass types to maintain healthy cool-season lawns.
Details:
1. ๐ฑ Understanding Fine Fescue and Weed Challenges
- The fine fescue lawn, noted for its dark color, contrasts with lighter-colored grassy weeds, indicating a clear visual distinction.
- Fine fescue was seeded 8 months ago, at the end of summer 2024, providing a timeline for lawn establishment.
- The main challenge is the presence of unwanted grassy weeds. Identifying specific weed types can guide management strategies.
- Potential solutions include targeted herbicides or manual removal to maintain the desired lawn aesthetic and health.

2.2. Limitations and Considerations for Fine Fescue
3. ๐ฟ Managing Unwanted Weeds: A Delicate Balance
- In heavily shaded lawns, fine fescue grass is commonly used to cope with low sunlight, promoting healthy grass growth and reducing weed proliferation.
- Unwanted plant growth often occurs in bare areas where no grass is intentionally planted, necessitating targeted management strategies.
- A strategic approach to weed management involves initially allowing weeds to grow, making them easier to identify and target for elimination later.
- Mulching can suppress weed growth by blocking sunlight and retaining soil moisture, proving effective in various lawn conditions.
- The use of selective herbicides allows for targeted weed elimination without damaging desirable grass species, a crucial aspect of maintaining lawn health.
- Regular lawn maintenance, including proper mowing, watering, and fertilization, enhances grass resilience against weed invasion.
- Understanding local weed species and their growth patterns can aid in developing effective, tailored management plans.
4. ๐งด Selecting Herbicides for Fine Fescue
- When dealing with fine fescue, it is crucial to choose herbicides carefully, as non-selective options like glyphosate or gluosinate can damage the grass.
- Specific herbicides must be selected to ensure the health and maintenance of fine fescue without causing harm.
- Examples of suitable herbicides for fine fescue include those that target specific weeds without harming the grass, such as certain formulations of 2,4-D or dicamba.
- It's recommended to consult with a turfgrass specialist to determine the most effective and safe herbicide options for fine fescue.
5. ๐พ Fine Fescue Success on Slopes
- Fine fescue can thrive on slopes despite not removing unwanted grasses, which is beneficial for minimizing labor costs and soil disruption.
- The presence of unwanted grasses did not hinder the growth of fine fescue, indicating its competitive advantage and resilience in challenging environments.
- A video documenting the fine fescue growth process on a hill was created, serving as a practical guide for those interested in similar landscaping projects.
- The growing conditions that favor fine fescue on slopes include its ability to establish quickly and tolerate shade from taller grasses.
- Challenges such as soil erosion and water runoff are mitigated by fine fescue's dense root system, which stabilizes the soil effectively.
6. ๐ Observations on Herbicide Application and Effects
- Establishing desired grass on hills is difficult, while undesirable weedy grass grows easily, indicating a need for strategic management.
- Beneath the overgrown weedy grass, fine fescue is thriving and needs to be preserved, highlighting the importance of selective herbicide use.
- The primary objective is to apply herbicide that targets the overgrown weedy grass without affecting the fine fescue, ensuring the preservation of desirable grass species.

8. ๐ฟ Mixing and Applying Pylex for Optimal Results
- Pylex is applied over a small area of 76 square feet and an additional 300 square feet of Kentucky bluegrass, illustrating its efficiency in covering large areas with minimal product.
- Ensure Pylex is not applied to warm-season grasses like Bermuda grass, Zoysia, or St. Augustine to prevent damage.
- Topramezone, the active ingredient in Pylex, is applied in small quantities of 1 to 2 ounces per acre, necessitating precise measurement tools as low as 0.1 ml for accuracy.
- For optimal results, mix Pylex with methylated seed oil at a ratio of approximately 10:1, using more oil than herbicide to enhance effectiveness.
- Target weeds include clover, broadleaf weeds, and the early stages of Bermuda grass and Quackgrass, with only half a gallon of mixture needed in a tank sprayer, showcasing the product's potency.
- Follow safety precautions and consider environmental conditions when applying Pylex to ensure safe and effective use.
9. ๐ผ Post-Application Observations: Fine Fescue Health
- Bleaching of warm season grasses like Bermuda becomes apparent between days 10 and 20 after Pylex application, indicating effective targeting of unwanted grasses.
- Fine fescue remains unaffected by Pylex, showcasing its selective action and suitability for preserving desired grass types.
- A consistent application schedule of Pylex is recommended, with treatments every 3 weeks for a total of 2-3 applications to effectively manage warm season grass presence.
- Non-selective glucosinate products result in complete die-off of treated areas, offering an alternative to glyphosate with similar efficacy.
- Kentucky bluegrass displays signs of nutrient deficiency after 14-15 weeks without treatment, as evidenced by fading and dog urine spots; fertilization is necessary to maintain health.
- Monitoring and treatment adjustments are crucial for sustaining the health and appearance of desired grass types, ensuring optimal lawn care.
