Quinclorac is a synthetic auxin-type herbicide (growth regulator) with activity against several annual grasses and some broadleaf weeds, especially barnyardgrass in rice systems. The 25% SC formulation is a liquid suspension of finely milled quinclorac particles in water with dispersing and wetting agents, designed to be diluted in water and applied with standard sprayers.

Key characteristics of quinclorac 25 SC herbicide:

Active ingredient: Quinclorac 25% w/v (250 g/L)
Formulation type: SC – suspension concentrate
Use pattern: Selective, mostly post-emergence in rice, cereals and turf
Target: Problem grasses (e.g. barnyardgrass) and some broadleaf weeds, depending on label

For buyers who want to buy quinclorac in a modern, user-friendly formulation, quinclorac 25% SC is an ideal option to position in professional crop and turf portfolios.

Mode of Action

Quinclorac acid belongs to quinoline carboxylic acid herbicide. Quinclorac is a selective herbicide used to control barnyard grass in rice fields. It belongs to hormone type quinoline carboxylic acid herbicide and is a synthetic hormone inhibitor. The medicament can be quickly absorbed by the germinating seeds, roots, stems and leaves, and rapidly transmitted to the stems and tops, causing weeds to die of poisoning, similar to the symptoms of auxin substances. It can effectively control barnyard grass in direct seeding field, and has good control effect on barnyard grass in 3-5 leaf period.

Role in sensitive grass weeds

In sensitive grass weeds (e.g. barnyardgrass, big dogwood, broadleaf signalgrass, and green dogwood), Quinclorac causes accumulation of tissue cyanide, inhibits root and shoot growth, and causes tissue discoloration and necrosis.

Weed Spectrum – Target Weeds

The quinclorac weed spectrum focuses mainly on difficult grass weeds, and in some registrations, certain broadleaf species. Depending on the country label, quinclorac 25% SC may control or suppress:

Grass weeds (key focus)
- Barnyardgrass (Echinochloa spp.) – primary target in rice
- Some other annual grasses (e.g. crabgrass, foxtail) where labelled
Broadleaf weeds (label-dependent)
- Certain small-seeded broadleaf species
- Some sedges or mixed weed populations in rice or turf (where authorised)

The exact weed list, growth stages and control spectrum must follow your national registration and product label. As a selective herbicide, correct timing and application conditions are critical for performance and crop safety.

Crop Uses

Without specifying application rates or spray intervals, typical professional uses of quinclorac 25% SC herbicide include, where registered:

Rice (Primary Market)

Quinclorac for rice is one of the most important market segments worldwide. In many rice systems, barnyardgrass and mixed grass–broadleaf infestations reduce yield and complicate water management. Quinclorac 25% SC is often used as a post-emergence herbicide in transplanted or direct-seeded rice, when weeds and crop are at appropriate stages as defined by the label.

Other Cereals & Grains

In some countries, quinclorac 25% SC may be registered for use in additional cereals or grain crops (subject to local regulations), targeting similar annual grass complexes and certain broadleaf weeds. The exact crop range depends on national labels.

Turf, Lawn and Amenity Grass

Quinclorac herbicide is also used in turf and lawn management (golf courses, sports fields, parks) to manage problem grasses and mixed weed populations where selectivity permits. The SC formulation supports uniform coverage and ease of use for professional turf managers.

Always check the approved crop list, timing and restrictions on your local product label before positioning quinclorac for sale in any specific segment.

Effectiveness against barnyard grass
Quinclorac is effective against barnyardgrass in rice paddies. It has a long application period and is effective from the 1-7 leaf stage.

Control of other weeds
Quinclorac is also effective in controlling weeds such as raindrops, field lily, watercress, duckweed, soapwort and so on.

Common Formulations
Common dosage forms of Quinclorac include 25%, 50%, and 75% wettable powder, 50% soluble powder, 50% water-dispersible granule, 25% and 30% suspension, and 25% effervescent granule.

Soil Residues
Residues of Quinclorac in soil are mainly through photolysis and degradation by microorganisms in the soil.

Crop Sensitivity
Certain crops such as sugar beets, eggplants, tobacco, tomatoes, carrots, etc. are very sensitive to Quinclorac and should not be planted in the field the following year after application, but only after two years. In addition, celery, parsley, carrots and other umbelliferous crops are also very sensitive to it.

Getting the right application period and dosage
In the rice-planting field, barnyard grass 1-7 leaf period can be applied, but need to pay attention to the amount of active ingredient mu, the water will be drained before the drug, the drug after the release of water back to the field and maintain a certain water layer. The direct field needs to be applied after the seedling 2.5 leaf stage.

Adopt the correct application technique
Spray evenly, avoid heavy spraying, and make sure the amount of water is sufficient.

Pay attention to weather conditions
Avoid high temperature during spraying or rain after spraying, which may cause flooding over the heart of the seedlings.

Symptoms of drug damage
In case of drug damage, the typical symptoms of rice are onion heart seedling (the heart leaves are rolled longitudinally and fused into onion tubes, and the tips of the leaves can be unfolded), the new leaves can not be extracted, and the new leaves can be seen rolled inward when peeling off the stalks.

Treatment measures
For the paddy fields that have been affected by the drug, measures can be taken in time to promote the recovery of seedling growth by spreading compound zinc fertilizer, spraying foliar fertilizer or plant growth regulator.
