## Overview

Primesource Quinclorac 1.5 Select is a selective, post-emergent liquid herbicide with 18.92% quinclorac, designed to control crabgrass and broadleaf weeds in residential and commercial turf. It offers up to 90 days of effective weed control, can be applied before or after seeding, and is formulated to protect tolerant turfgrass species like Bermuda grass while eliminating unwanted weeds.

## Description

Quinclorac 1.5L Select™ is a selective, post-emergent herbicide that can be applied to many types of turf, both residential and non-residential, to control a variety of weeds. Quinclorac 1.5L Select™ can be applied from 7 days before seeding and up to 28 days after emergence on selected weeds. Quinclorac 1.5L Select™ is an auxin agonist and is classified as a quinoline carboxylic acid. It is absorbed by foliage and roots and translocated throughout the plant. The control symptoms exhibited by broadleaf weeds include leaf and stem curl or twisting, and chlorosis. Susceptible grasses demonstrate stunting, chlorosis, and gradual reddening followed by necrosis and death. Apply Quinclorac 1.5L Select™ to actively growing weeds as post-emergent broadcast or spot sprays using the turf species, rate and growth stages indicated on the label. The use of Quinclorac 1.5L Select™ before or after seeding or overseeding a turf area will not significantly interfere with the turfgrass seed germination and growth of those grass types identified as tolerant or moderately tolerant on the label.

Review: I'll use again but only in certain circumstances - This product works extremely well for Crabgrass but I did find that a second application severely stresses the Bermuda grass that I'm trying to cultivate. It's weird because the first application only killed about half of the crabgrass and zero Bermuda grass. But the second application killed 100% of the crabgrass and probably about 30% of the Bermuda grass
Review: Works on foxtails - Great, it killed most of my foxtails, yet I need to apply a 2nd time to get the remainder of them. Although it is a little pricey

## Questions & Answers

**Q: Will this product eliminate tprpedo grass without damaging surronding Bermuda grass?**
A: This product is safer to use on Bermuda than Tenacity. It did not kill my Bermuda. See my review for pics.

**Q: Why are there two containers in one? One container has a .5 oz of liquid and the other container has 7.5 oz of liquid. Which liquid is which?**
A: The product comes with a specialized container called a tip and pour.  It allows the user to measure the amount of product to be dispensed from the container.  To use, simply squeeze the bottle and the liquid will fill the smaller reservoir to the desired application amount.

**Q: How long before you should mow**
A: Per the Manufacturer's directions:
DO NOT mow 2 days before or after applying Quinclorac 1.5L Select to maximize weed control and minimize potential turf injury. Clippings from the first three mowings after application should be left on the treated area.

**Q: When can you spray this on your grass**
A: Quinclorac is a post emergent poison- I recommend applying early spring-early summer (depending on your region and when your last frost is).

### ⭐⭐⭐⭐⭐ Works on foxtails
*by C***S on July 1, 2025*

Great, it killed most of my foxtails, yet I need to apply a 2nd time to get the remainder of them. Although it is a little pricey

### ⭐⭐⭐⭐ Effective, but
*by W***M on October 2, 2022*

I used this on crab grass in a Bermuda lawn - in mid September, North Georgia. Highly and quickly effective on the weeds but it really set back the Bermuda. I think it would have fine if I used it earlier in the growing season. Cool temperatures and dry conditions have probably slowed the Bermuda recovery. Next year I will mix a little weaker than recommend.
