From Grok as I was interested between two formulas. "This new formula appears could be in ground for UP TO 15 years and 200x more chronically toxic than glyphosate.Comparative Effectiveness- Broad-spectrum control: - Glyphosate is generally more effective for non-selective, broad-spectrum control, as it kills most plants down to the roots with a single application. It is particularly reliable for deep-rooted perennials and mixed weed populations. - New Formula is effective for mixed populations of grasses and broadleaf weeds due to the complementary actions of triclopyr (broadleaf) and fluazifop (grasses), with diquat providing quick burndown. However, it may be less effective on larger or perennial weeds due to diquat's contact-only action.- Specific use cases: - Poison ivy and woody plants: Triclopyr outperforms glyphosate for woody plants and vines like poison ivy, especially when applied to cut stems or foliage. - Grasses: Fluazifop is highly effective against grasses, potentially outperforming glyphosate for certain grass species. - Quick results: The new formula's diquat component provides faster visible results (hours vs. days), which may be preferred for aesthetic purposes, though it doesn't ensure root kill.- Limitations: - The new formula may require multiple applications for complete control of perennial weeds, as diquat only burns top growth. - Glyphosate's single active ingredient simplifies targeting all weeds, whereas the new formula's selective components (triclopyr for broadleaf, fluazifop for grasses) may not address all weeds equally well in every scenario.Health and Environmental Considerations- Glyphosate: - Linked to potential health risks, including non-Hodgkin's lymphoma, leading to its phase-out in consumer Roundup products. - Low environmental persistence (half-life ~6.5 days) and minimal soil activity reduce environmental impact.- New Formula: - Contains chemicals (diquat, triclopyr, fluazifop) that may pose greater risks for chronic health issues (e.g., reproductive dysfunction, kidney/liver damage) and environmental harm (e.g., toxicity to birds, fish, crustaceans). Diquat is particularly concerning, being 200 times more chronically toxic than glyphosate and banned in the EU. - Triclopyr and diquat have longer soil persistence (6 weeks and up to 15 years, respectively), increasing risks to non-target plants and ecosystems.Conclusion- Effectiveness: - Glyphosate-based Roundup is generally more effective for broad-spectrum, non-selective weed control, especially for deep-rooted perennials, due to its systemic action and ability to kill roots with fewer applications. - The new Roundup formula (Triclopyr, Fluazifop, Diquat) is equally or more effective in specific scenarios, such as controlling mixed populations of grasses and broadleaf weeds, woody plants, or poison ivy, and provides faster visible results due to diquat. However, it is less effective for larger or perennial weeds that require root kill, as diquat's contact action necessitates repeat applications. - For targeted applications (e.g., poison ivy, mixed grass/broadleaf weeds), the new formula may be preferable due to its tailored active ingredients. For general, non-selective weed control, glyphosate is typically more reliable.- Recommendation: - Choose glyphosate-based Roundup for broad-spectrum control of mixed weeds, especially perennials, in non-sensitive areas where soil persistence is not a concern. - Choose the new formula for specific weed types (e.g., woody plants, grasses) or when rapid visual results are desired, but be prepared for potential repeat applications and exercise caution around desirable plants due to triclopyr's soil persistence. - Always read and follow product labels for safe application, as the new formula has specific restrictions (e.g., no use in vegetable gardens, maximum application rates). - Consider non-chemical alternatives (e.g., hand weeding, flame weeding) or organic herbicides if health and environmental concerns are a priority."
