When it comes to tackling tough crabgrass and a host of other grassy and broadleaf weeds, Quintessential Crabgrass Control is a game-changer for both DIYers and lawn care pros. This advanced, professional-grade herbicide offers reliable, selective control that keeps your lawn looking its best. Here’s what you need to know about using Quintessential to maintain a healthy, weed-free lawn.
What Is Quintessential Crabgrass Control?
Quintessential is a selective, post-emergent herbicide powered by H-Value Technology—a proprietary additive that boosts the absorption and effectiveness of quinclorac, its active ingredient. This unique formulation means faster weed control, improved performance in drought or rainfast conditions, and superior results even on mature crabgrass. Quintessential is available as a liquid concentrate, making it easy for DIYers to achieve professional results with precision application.
What Weeds Does Quintessential Control?
Quintessential is highly effective against:
- Grassy Weeds: Crabgrass (large & smooth, including the tough 3–5 tiller stage), foxtail, signal grass, torpedo grass, barnyardgrass.
- Broadleaf Weeds: Clover, black medic, daisy, dandelion, morning glory, wild violet, and more.
This broad spectrum makes Quintessential a versatile choice for both spot treatments and larger problem areas in home lawns and non-residential turf.
When Should You Apply Quintessential?
Timing is key for effective weed control:
- Post-Emergent Applications: Apply when crabgrass and other target weeds are actively growing. Quintessential is especially effective on crabgrass at all growth stages, including the problematic mid-tiller stage.
- Cool-Season Lawns: (Kentucky Bluegrass, Tall Fescue, Ryegrass) — Apply from spring through summer as weeds emerge.
- Warm-Season Lawns: (Bermuda, Zoysia, Hybrid Bermuda) — Apply during active growth.
Note: Do not use on Centipede, Bahia, or St. Augustine grasses. - Seeding Flexibility: Can be applied from 7 days before seeding up to 28 days after weed emergence, making it ideal for renovation projects.
How to Apply Quintessential
- Choose the Right Size: Available in 7.5 oz (covers up to 5,000 sq ft) and 64 oz (covers up to 42,600 sq ft) bottles.
- Mixing: Add 1.45 oz of Quintessential per gallon of water in a battery or pump sprayer. Apply evenly across 1,000 sq ft of lawn.
- Surfactant Required: For best results, use a methylated seed oil or a non-ionic surfactant to help the herbicide stick and penetrate weed leaves.
- Application Method: Spot spray or zone spray for targeted control, or blanket spray for widespread infestations.
- Watering In: Do not water or irrigate for 24 hours after application. If no rainfall occurs within 2–7 days, irrigate with at least ½ inch of water.
Integrating Quintessential Into Your Lawn Care Routine
- Monitor for Weeds: Regularly inspect your lawn for new weed growth and treat as needed.
- Combine with Good Practices: Proper mowing, watering, and fertilization help your lawn recover from weed stress and resist future invasions.
- Follow Label Rates: Avoid over-application by sticking to recommended rates and annual limits.
Safety and Environmental Tips
- Keep Children and Pets Off Treated Areas: Until the spray has dried.
- Avoid Drift: Do not spray on windy days or near desirable plants.
- Storage: Store in a cool, dry place away from sunlight and out of reach of children.
- Check Local Regulations: Not for use in Alaska, California, or Hawaii. Always verify product registration in your state.
