## Overview

Primesource Quinclorac 1.5 Select is a powerful, selective liquid herbicide with 18.92% active quinclorac, designed for both residential and commercial turf. It provides up to 90 days of targeted crabgrass control over 1000 square feet, safely applied before or after seeding. Absorbed systemically, it disrupts weed growth while preserving your lawn’s health, making it a top choice for golf courses, sod farms, and home lawns alike.

## 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.

## 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).
