Cyhalofop-butyl Technical FAQ Section 1
Q: What is the recommended application rate for Cyhalofop-butyl Technical?
A: The typical application rate ranges from 60-120 g active ingredient per hectare, depending on weed species and growth stage. For annual grasses, 60-90 g ai/ha is usually sufficient, while perennial grasses may require up to 120 g ai/ha. Always follow local regulations and label instructions.
Q: How does Cyhalofop-butyl Technical work as a herbicide?
A: Cyhalofop-butyl Technical inhibits acetyl-CoA carboxylase (ACCase), a key enzyme in fatty acid biosynthesis. This disruption prevents the formation of cell membranes in meristematic tissues, ultimately leading to weed death. The compound is absorbed by foliage and translocated to growing points.
Advantages of Cyhalofop-butyl Technical
- Excellent control of grass weeds in rice, including resistant biotypes
- Selective action with minimal effect on broadleaf crops
- Rapid absorption and translocation within target weeds
- Flexible application timing from early to late post-emergence
- Rainfast within 1-2 hours after application
- Low use rates compared to alternative herbicides
Cyhalofop-butyl Technical FAQ Section 2
Q: What is the proper storage condition for Cyhalofop-butyl Technical?
A: Store in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Maintain temperature between 5-30°C. Keep containers tightly closed when not in use. Avoid contact with oxidizing materials and store separately from food and feed.
Q: What safety precautions should be taken when handling Cyhalofop-butyl Technical?
A: Always wear appropriate personal protective equipment including chemical-resistant gloves, protective clothing, and eye protection. Avoid inhalation of vapors or mists. In case of skin contact, wash immediately with plenty of water. If eye exposure occurs, rinse cautiously with water for several minutes.

Application Guidelines
- Apply when target weeds are actively growing (2-5 leaf stage for best results)
- Use sufficient water volume (200-400 L/ha) for thorough coverage
- Add recommended adjuvant if required for improved performance
- Avoid application under drought stress or extreme temperatures
- Do not apply if rainfall is expected within 1 hour of treatment
Cyhalofop-butyl Technical FAQ Section 3
Q: What is the spectrum of weed control with Cyhalofop-butyl Technical?
A: Cyhalofop-butyl Technical effectively controls numerous grass weeds including Echinochloa spp. (barnyardgrass), Leptochloa spp., Digitaria spp. (crabgrass), Setaria spp. (foxtail), and other annual and perennial grasses. It has limited activity on broadleaf weeds or sedges.
Q: What is the environmental profile of Cyhalofop-butyl Technical?
A: Cyhalofop-butyl Technical has moderate persistence in soil (DT50 10-50 days) and degrades primarily through microbial action. It has low volatility and moderate mobility in soil. The compound is slightly toxic to fish and aquatic invertebrates, so avoid direct application to water bodies.
Compatibility Information
Cyhalofop-butyl Technical can be mixed with many commonly used pesticides, but always conduct a compatibility test before tank mixing. Some known compatible products include:
- Broadleaf herbicides for rice (e.g., bentazon, propanil)
- Certain insecticides (check specific product labels)
- Fertilizer solutions (verify compatibility for each formulation)
Avoid mixing with strongly alkaline products or those containing sulfur as these may reduce efficacy.
