Main Functions

Cyhalofop-Butyl 40% EC is mainly used in registered post-emergence paddy rice programs where selected annual grass weeds affect field cleanliness, crop establishment, and rice production planning.

It can help:

• Support registered post-emergence rice grass weed-management programs
• Support selected annual grass weed directions where locally approved
• Support barnyardgrass-type pressure where local registration allows
• Support single-active Cyhalofop-Butyl rice herbicide positioning
• Provide HRAC Group 1 ACCase inhibitor activity
• Provide a 40% EC formulation direction for local rice herbicide portfolios
• Support rice grass weed-focused herbicide programs
• Support local registration review and distributor product positioning

This product should be positioned as a Cyhalofop-Butyl 40% EC single-active rice grass herbicide for approved post-emergence weed-management programs. It should not be presented as a universal rice herbicide for all weeds, all rice systems, or all field conditions.

For local partners, this product provides a clear SunAgro branded Cyhalofop-Butyl 40% EC rice herbicide direction for registration review and rice herbicide market distribution.

Mode of Action

Cyhalofop-Butyl is classified as HRAC Group 1. It works as an ACCase inhibitor and belongs to the aryloxyphenoxypropionate / FOP herbicide direction.

ACCase inhibition affects fatty acid synthesis in susceptible grass weeds. When this process is disrupted, sensitive grass weeds gradually stop normal growth and later show visible injury under suitable field conditions.

Cyhalofop-Butyl 40% EC should be positioned as a rice grass herbicide. Broadleaf weeds and sedges are not the main positioning for this product page unless local registration clearly supports related claims.

Because repeated use of the same herbicide group can increase resistance risk, Cyhalofop-Butyl 40% EC should be used within integrated rice weed-management programs. Rotation or approved mixture programs with herbicides from different groups should follow local label directions and resistance-management guidance.

Target Weed Directions

Cyhalofop-Butyl 40% EC can be reviewed for registered rice weed-management programs where HRAC Group 1 ACCase inhibitor activity is needed.

Common weed directions may include:

• Selected annual rice grass weeds where locally approved
• Barnyardgrass-type weeds where approved
• Echinochloa species directions where locally registered
• Sprangletop-type grass directions where approved
• Leptochloa species directions where local registration supports the claim
• Other selected annual grasses according to approved local label
• Young grass weed-stage directions according to approved local label
• Broadleaf weeds are not the main positioning
• Sedge weeds are not the main positioning
• Other approved weed species according to local registration and approved label claims

This product should be positioned mainly for post-emergence grass weed-management programs in paddy rice. It should not be promoted as complete control of all rice weeds unless local registration clearly supports the relevant weed spectrum.

Final weed spectrum, rice system, dosage, application timing, water-management requirement, rice stage, weed stage, tank-mix direction, interval, maximum application number, safety interval, residue requirement, and use restriction must follow local registration and approved label directions in the destination market.

Suitable Crops and Application Areas

Cyhalofop-Butyl 40% EC should be reviewed mainly for registered paddy rice weed-management programs. The final rice system and crop scope must follow the approved local label.

Paddy Rice Programs

Paddy rice is the core crop direction for this page.

This product can be reviewed where local registration supports selective post-emergence grass weed management in rice fields. Product positioning should focus on selected annual grass weeds, barnyardgrass-type pressure, water-management conditions, rice crop stage, and HRAC Group 1 herbicide planning.

Post-Emergence Rice Grass Weed Programs

Cyhalofop-Butyl 40% EC is mainly positioned for post-emergence rice grass weed-management programs where local label directions allow this timing.

Application planning should consider rice stage, weed stage, water level, field condition, weather, crop safety, tank-mix restrictions, and local label requirements.

Barnyardgrass-Type Pressure Programs

Barnyardgrass-type pressure is an important semantic direction for this product page.

Cyhalofop-Butyl 40% EC can be reviewed where local registration supports post-emergence management of barnyardgrass-type weeds in rice fields. Final weed species, crop stage, weed stage, dosage, and timing must follow the approved local label.

Direct-Seeded Rice Systems

For direct-seeded rice systems, this product can be reviewed only where local registration supports this use direction.

Direct-seeded rice programs may face strong grass weed pressure. Product suitability depends on rice stage, weed stage, water management, crop safety, and approved local label directions.

Transplanted Rice Systems

For transplanted rice systems, Cyhalofop-Butyl 40% EC can be reviewed where local label directions support this rice production system.

Use directions should consider transplant stage, crop recovery, water level, weed emergence, application timing, and local crop safety requirements.

Rice Herbicide Portfolio Development

For local distributors and crop protection channels, Cyhalofop-Butyl 40% EC can serve as a single-active rice grass herbicide direction within a wider paddy rice weed-management portfolio.

It can be positioned alongside other rice herbicide products depending on local registration, weed pressure, resistance history, rice production system, water-management practice, and distributor product strategy.

Application Guidance

Cyhalofop-Butyl 40% EC should be used according to the approved local label. Because rice herbicide selectivity and weed-control performance depend on rice system, crop stage, water management, dosage, weed stage, timing, weather, field condition, and tank-mix practice, correct use direction is important.

General use considerations include:

• Use only where Cyhalofop-Butyl is locally registered and approved.
• Confirm approved crop scope, rice system, weed spectrum, dosage, rice stage, weed stage, timing, water-management requirement, interval, PHI, MRL, and maximum application number.
• Position the product mainly for registered post-emergence paddy rice grass weed-management programs.
• Use in direct-seeded or transplanted rice systems only where local label supports the system.
• Do not apply to crops, weeds, or areas not listed on the approved label.
• Check rice variety sensitivity, crop condition, water management, weather, tank-mix restrictions, and crop stage before use.
• Avoid repeated reliance on HRAC Group 1 herbicides.
• Rotate or combine with herbicides from different groups where locally approved.
• Use as part of integrated rice weed-management programs.
• Follow local worker safety, environmental, residue, drift-control, water-management, and crop safety requirements.
• Protect the EC formulation from leakage, high heat, fire sources, direct sunlight, and improper storage.

This information is for product communication only. Final crop scope, rice system, weed claim, dosage, timing, crop stage, weed stage, water-management requirement, tank-mix direction, interval, safety requirement, resistance-management rule, and use restriction must follow the approved local label.

EC Formulation Features

EC means emulsifiable concentrate. Cyhalofop-Butyl 40% EC is a liquid formulation designed to form an emulsion after dilution in water according to approved label directions.

Compared with dry formulation directions, EC provides a liquid emulsifiable concentrate product identity. It is suitable for markets that need a Cyhalofop-Butyl single-active rice grass herbicide direction for registered post-emergence programs.

Key features include:

• 40% emulsifiable concentrate formulation
• Cyhalofop-Butyl single-active identity
• HRAC Group 1 ACCase inhibitor direction
• Rice grass herbicide product positioning
• Suitable for registered post-emergence grass weed-management programs in paddy rice
