What Makes It Pro Grade?

Built For Professional Results

Quintessential delivers the kind of performance professionals rely on. This means quicker visible results, stronger overall control, and dependable performance even during tough conditions like drought or right after rain. It’s designed to handle the toughest crabgrass stages and keep lawns looking clean and healthy from start to finish.

A rainfast comparison measures the time needed between a spray application and a rain event for the product to remain effective. In a rainfast comparison with a competitive quinclorac product, the results indicate efficacy at 2 hours and beyond with Quintessential®, while it takes 12 hours for a competitive product to achieve the same level of effectiveness.

When to Apply

Quintessential® should be applied while your lawn is actively growing and weeds are visible. For best results, treat early before crabgrass matures, but it’s effective even on tougher stages. Avoid spraying during extreme heat or drought stress.

PRO TIPS

It is best to apply when crabgrass is young or just starting to appear.
Avoid hot, dry, or stressed turf conditions.
Apply to dry grass and allow it to dry before watering or rain.
If you plan to seed, apply Quintessential at least 7 days before and then not again until 28 days after emergence.
Do not mow 2 days before or 2 days after.
Wait 24 hours after application to apply granular fertilizer.
To ensure this product is safe for your grass type, refer to the FAQ's further down on this page.
PPE is recommended while applying( rubber/plastic boots, gloves, long pants, long sleeves, nitrile gloves, and goggles/glasses)

Pro Tips for Best Results

Watch Temperature & Moisture

Use when the grass is actively growing and not heat-stressed.

Mix & Apply on Calm Days

Apply when winds are low (less drift), so coverage is even and uptake is efficient.

Spray Evenly

Maintain steady pressure and overlap slightly to ensure uniform coverage across all turf areas.

Rinse Sprayer After Use

Always clean out your equipment after application to avoid residue or buildup that could affect future treatments.

Keep It Safe

Store in a cool, dry place.
