Quinclorac Multi-Purpose Herbicide is perfect for controlling mattongrass, clover and other stubborn weeds in lawn and agricultural settings.

What is Quinclorac?

Quinclorac is a selective herbicide primarily used in turf management and agriculture to control a range of tough broadleaf and grassy weeds. Known for its effectiveness against crabgrass and other persistent weeds, quinclorac is a popular choice for homeowners, landscapers, and agricultural professionals alike.

What is Quinclorac Herbicide?

Quinclorac works as a systemic herbicide, meaning it is absorbed and transported throughout the plant, causing its eventual demise. This makes it particularly effective on stubborn weeds that are difficult to kill with contact-only herbicides.

How Does Quinclorac Work?

Quinclorac targets specific enzymes in weeds that are essential for cell division and growth. By disrupting these enzymes, quinclorac prevents the plant from growing, ultimately causing it to die off. Its unique mode of action makes it effective on many weeds that other herbicides struggle to control.

What is Quinclorac Used For?

Quinclorac is widely used to control a variety of weeds in turf areas such as golf courses, residential lawns, and sports fields. It is also utilized in agriculture for managing weeds in fields of crops like rice. Quinclorac effectively controls weeds such as crabgrass, foxtail, barnyardgrass, and clover.

Quinclorac Kills What Weeds?

Quinclorac is especially effective on:

• Crabgrass
• Clover
• Barnyardgrass
• Foxtail
• Dandelion

Its versatility allows it to target both grassy and broadleaf weeds, making it highly adaptable for turf and field applications.

Application and Mixing

How to Apply Quinclorac

For best results, apply quinclorac when weeds are actively growing, typically in warmer weather. Ensure that the product is applied evenly across the lawn or field, covering all target weeds thoroughly.

How to Mix Quinclorac

Quinclorac is commonly mixed with water before application. Use the recommended ratio provided on the product label, typically adding a surfactant to improve absorption by the weeds.

How Much Quinclorac per Gallon of Water?

The standard rate is approximately 1 tablespoon per gallon of water for spot treatments, but always refer to the product label for precise measurements based on the targeted weed and area.

How Much Quinclorac per Acre?

For broadcast applications, the typical rate is around 1 pound per acre. This rate may vary depending on the weed species and the specific formulation of quinclorac used.

How Long After Quinclorac Can I Seed?

After applying quinclorac, wait at least 21 days before seeding to allow the herbicide to break down in the soil. This prevents any negative impact on new seedlings.

Can You Mix Quinclorac and 2,4-D?

Yes, quinclorac can be mixed with 2,4-D for a broader spectrum of weed control. This combination is effective for targeting a wider range of both broadleaf and grassy weeds.

Quinclorac begins to work within 7 to 10 days, but full weed control may take up to 21 days as it systematically kills the targeted weeds.

How Long Does It Take for Quinclorac to Kill Crabgrass?

Crabgrass control may start showing results within 10 to 14 days. Mature crabgrass may take longer or require additional treatments for complete control.

Will Quinclorac Kill Mature Crabgrass?

Yes, quinclorac can kill mature crabgrass, though it may require a higher application rate or multiple treatments due to the resilience of older plants.
