What is Quinclorac?

Quinclorac is a selective herbicide used post-emergently to control invasive broadleaf weeds, sedge grasses, and crabgrass. It works systemically and can be absorbed by germinating seeds, roots, and leaves.

Quinclorac is used in both agricultural and non-agricultural settings. It may be used to treat industrial and residential turf grass, parks, sports fields, sod farms, and golf courses. It is especially highly regarded for its superior Clover and Crabgrass control.

How Does Quinclorac Work?

Mode of Action

Quinclorac is a synthetic auxin. This means that Quinclorac's mode of action is that it operates as a plant growth regulator by imitating natural plant hormones called auxins. Auxins, found in all plant life, regulate the amount, type, and direction of plant growth and are mostly found at the tips of plant roots and shoots.

Quinclorac enters treated plants through the leaves and roots and replaces natural auxins at binding sites, causing abnormal growth patterns and disrupting the plant's growth processes. 

The chemical builds up in the plant's growth points, leading to rapid overgrowth and eventual plant death. Death can usually occur in as little as a few days to a couple of weeks.

Benefits of Quinclorac

Quinclorac is a selective post-emergent active ingredient, meaning it targets specific weeds and has no harmful effects on desirable grass, which may surround the offending weed when applied. Aside from targeting crabgrass primarily, Quinclorac can also eliminate weeds such as dandelion and clover, which may come up in areas where the grass is stressed.

Use Quinclorac for weed control on residential and commercial lawns, golf courses, sports fields, and sod farms.

Drawbacks of Quinclorac

While Quinclorac is effective, not every grass type can tolerate an application. A selective application may damage sensitive grasses like Bahiagrass, Centipedegrass, and St. Augustine grass. Check the label for a list of grasses that can tolerate Quinclorac.

Is Quinclorac Safe?

Quinclorac is safe to use when applied carefully according to the label directions. Stay off the treated area until the product has fully dried.

While it is a relatively safe chemical to use, it is still highly recommended that you wear protective equipment (PPE) before applying quinclorac. Gloves, protective glasses, and long-sleeve clothing should be the minimum level of protection when handling this chemical. Please refer to the product label for specific safety instructions.

What To Expect

When applying Quinclorac, spray enough to moisten the leaf surface. Quinclorac is rainfast within an hour, meaning it will remain on the plant even if it rains rather than be washed off. About 2 to 7 days later, irrigating the treated plant area is recommended so it filters down into the soil to be picked up by the broadleaf plants you are trying to get rid of. 

After a week, you should notice that the areas of crabgrass and weeds that you treated are dying and turning brown. Be sure to check the product label to see the level of tolerance your desired grass can take, as some vegetation is more tolerant of Quinclorac than others.
