Cyhalofop-butyl 200g/L EC is a systemic herbicide formulated as an emulsifiable concentrate, designed for effective post-emergent control of annual gramineous weeds in rice paddies. With Cyhalofop-butyl as the active ingredient (CAS No. 122008-85-9), it selectively targets weeds such as Echinochloa crus-galli, Setaria spp., and Leptochloa chinensis, while remaining harmless to rice crops.
This product operates by inhibiting acetyl-CoA carboxylase (ACCase) in susceptible grass species, interrupting lipid biosynthesis, and halting cell growth at the meristem. Its unique metabolic pathway in rice allows for rapid detoxification into an inactive diacid form, ensuring excellent crop selectivity and minimal phytotoxicity.
Key attributes include:
High efficacy on key gramineous weeds in paddy ecosystems.
Outstanding crop safety with no impact on rice development.
Fast degradation in water and soil, minimizing residue risk.
Suitable for both transplanted and direct-seeded rice fields.
OEM-ready formulation, customizable in packaging and labeling.
This formulation is ideal for distributors seeking high-performance herbicides with proven safety profiles for the Asian, African, and Latin American rice markets.
Cyhalofop-butyl is a highly selective ACCase (Acetyl-CoA Carboxylase) inhibitor, designed to disrupt lipid biosynthesis in susceptible grassy weeds. By targeting the enzyme responsible for fatty acid production, Cyhalofop-butyl halts cell membrane formation and growth in weed meristematic tissues, leading to necrosis and plant death.
In rice plants, Cyhalofop-butyl undergoes rapid metabolism into a non-toxic diacid form, which does not interfere with rice ACCase enzymes. This differential metabolic pathway ensures high selectivity, allowing it to eliminate problematic weeds like Echinochloa crus-galli and Setaria spp. without harming rice crops.
The product is absorbed through weed foliage and translocated to the growing points, where it inhibits lipid synthesis at the cellular level, stopping development within days. Because of this systemic movement, even partially sprayed weeds can be controlled effectively.
Rapid translocation ensures quick onset of action
Visible symptoms such as chlorosis and necrosis appear within 2–5 days
No effect on Cyperaceae or broadleaf weeds, enabling focused gramineous control
Low persistence in water and soil, supporting crop rotation and environmental safety
This mode of action makes Cyhalofop-butyl 200g/L EC an essential tool for post-emergence weed management programs in modern rice cultivation.
Cyhalofop-butyl 200g/L EC is specifically formulated to control a broad spectrum of gramineous (grass-type) weeds in rice fields, both in transplanted and direct-seeded systems. It does not affect broadleaf or sedge weeds, making it ideal for integrated and selective weed control strategies.
This formulation is particularly effective against the following common and economically damaging grass weeds in paddy fields:
Echinochloa crus-galli (Barnyardgrass)
Echinochloa colonum
Leptochloa chinensis
Setaria viridis (Green foxtail)
Digitaria spp.
Ischaemum rugosum
Eleusine indica (Goosegrass)
These weeds compete aggressively with rice for nutrients, water, and sunlight, significantly reducing yield if left untreated.
To achieve optimal weed control and rice crop safety, apply Cyhalofop-butyl under the following timing recommendations:
Transplanted Rice: Apply 7–15 days after transplanting (DAT) when weeds are at the 2–4 leaf stage
Direct-Seeded Rice: Apply 10–20 days after seeding (DAS) when weeds are emerging but before they reach advanced tillering stages
Drain Water Before Application: Ensure at least 2/3 of weed leaf area is exposed before spraying
Avoid Late Application: Weeds past the 5-leaf stage may show reduced sensitivity
Early and timely intervention ensures effective absorption and systemic movement, maximizing control results and reducing the risk of weed competition.
Cyhalofop-butyl 200g/L EC is a systemic post-emergence herbicide applied via foliar spray. Its active ingredient is absorbed through leaves and transported to the meristematic zones of grass weeds, ensuring rapid inhibition of growth and eventual plant death.
Application rates vary depending on rice growth stage, weed pressure, and field conditions:
Rice Type | Dosage (ml/ha) | Application Stage |
---|---|---|
Transplanted Rice | 750–1000 ml/ha | 7–15 days after transplanting (DAT) |
Direct-Seeded Rice | 800–1200 ml/ha | 10–20 days after sowing (DAS) |
To ensure effective control:
Drain water from the field 24 hours before spraying to expose weeds.
Use a knapsack sprayer or boom sprayer with a fine, even nozzle.
Ensure uniform spray coverage, especially on the leaf surfaces.
Re-flood the field 12–24 hours after application to retain herbicide efficacy.
Do not apply during rain or within 6 hours of expected rainfall to maintain residual activity.
This precise application strategy ensures maximum herbicide uptake and long-lasting weed suppression while safeguarding rice crop health.

In the lowland paddies of Vietnam, a rice farmer faces heavy infestation of Echinochloa crusgalli just weeks after transplanting. Traditional herbicides either burn the rice tips or leave residues that affect the second crop.
After switching to Cyhalofop-butyl 200g/L EC, the farmer applies it at the 3-leaf stage of the weeds, carefully draining the field to expose foliage. Within days, the barnyard grass shows clear signs of withering, and the rice continues to grow unaffected. The field stays clean until canopy closure—saving labor and reducing yield loss.
A commercial rice farm using direct-seeded systems deals with rapid grass weed emergence after sowing. Because tillage is minimal and labor costs are high, early weed suppression is critical.
The farm uses Cyhalofop-butyl at 12 DAS via boom sprayer, targeting young weeds before they outgrow the rice. The product’s quick translocation and crop safety allow the farmer to maintain moisture without delaying irrigation—supporting efficient, large-scale weed control without harming productivity.
In a rural region of West Africa, a small-scale rice grower faces weed pressure during the rainy season. Without access to mechanical sprayers or precision tools, herbicide choice is limited.
By applying Cyhalofop-butyl EC with a simple knapsack sprayer and following label instructions (ensuring 2/3 of the weed is exposed), the grower sees excellent suppression of Setaria and Echinochloa species. The rice grows clean, and the field doesn’t require re-treatment, reducing both cost and manual labor.
A farm in China rotates rice with corn and leafy vegetables, requiring herbicides that leave no harmful residues in soil or water. Many older herbicides compromise food safety or delay planting of the next season’s crop.
Cyhalofop-butyl 200g/L EC degrades rapidly, both in the flooded field and in aerobic soil. After use, residue levels are minimal and safe for follow-up crops—meeting both domestic and international residue standards, making it a preferred choice for certified exporters.
Cyhalofop-butyl is highly effective against major grass weeds in rice fields, including Echinochloa crus-galli (barnyard grass), Setaria spp., and Leptochloa chinensis. However, it has limited or no effect on sedges (Cyperaceae) and broadleaf weeds, which may require separate treatment.
Yes. Cyhalofop-butyl demonstrates excellent selectivity for rice due to the crop’s ability to rapidly metabolize the active ingredient. It can be safely used in both transplanted and direct-seeded rice systems when applied according to label recommendations.
For optimal results, apply when target grass weeds are at the 2- to 4-leaf stage. Application should be done after draining the field so that at least two-thirds of the weed foliage is exposed, allowing for effective uptake through the leaves.
Yes, it is compatible with many broadleaf and sedge herbicides. However, always perform a jar test or consult with agronomists before mixing. Avoid mixing with highly alkaline solutions or oil-based adjuvants unless specified.
Cyhalofop-butyl degrades rapidly in soil and water and has minimal residual impact on subsequent crops. Its favorable environmental profile makes it suitable for use in certified crop production programs.
