1 fl oz = 2 tablespoons = 6 teaspoons, so 0.17 fl oz ≈ 1 teaspoon.
1. 🌡️ Check Soil Temperature
Apply when soil temperature is consistently above 40°F. Specticle can be applied earlier than many pre-emergents.
2. 📏 Determine Weed Pressure
Assess your weed pressure level (light, moderate, heavy) to determine the correct application rate.
3. ⚖️ Calculate Application Rate
Use the rate chart above to determine exact product amount needed for your lawn size and weed pressure.
4. 🚿 Apply Uniformly
Use calibrated spray equipment for even distribution. Ensure complete coverage with no skips or overlaps.
5. 💧 Activate with Water
Apply 0.25-0.5 inches of irrigation within 30 days to activate the herbicide barrier.
6. 📅 Record Application
Document application date, rate, and conditions for future reference and planning.
7. 👀 Monitor Performance
Watch for weed control effectiveness over the following months. Specticle provides long-lasting protection.
8. 🔄 Plan Next Application
Based on control duration, plan your next application 6-8 months later.
