Cyhalofop-butyl 12% + Metamifop 8% EC
Cyhalofop-butyl 12% + Metamifop 8% EC is a selective post-emergence rice herbicide used mainly for annual grass weed control in paddy fields. This formulation is designed for rice programs that need a clear grass-control solution after weed emergence, especially when early grassy weeds begin to compete with the crop. Cyhalofop-butyl is widely used in rice as a post-emergence herbicide, and metamifop is also used in rice for annual grass weed control.
This herbicide is best understood as a rice-field grass herbicide, not a broad non-selective weedicide for every weed group. The main role of the formulation is to control grassy weeds in rice, with the strongest fit in early post-emergence use. Marketed products with this same combination are positioned the same way in rice.

Main Functions / What It Does
Cyhalofop-butyl 12% + Metamifop 8% EC is mainly used to control annual grass weeds after emergence in rice. Its purpose is to reduce grass competition during the active growth stage of the crop, when untreated grassy weeds can spread quickly and weaken field cleanliness and crop development. Rice-focused market pages for this combination consistently position it as a post-emergence grass herbicide.
This formulation is most suitable when the weed problem is mainly on the grass side, not when the main pressure comes from broadleaf weeds or sedges. That is the cleanest way to place the product in a rice herbicide program. Cyhalofop-butyl and metamifop are both used in rice systems for grass weeds such as barnyardgrass, crabgrass, goosegrass, and other annual grasses.
Mode of Action
Cyhalofop-butyl and metamifop both work in the ACCase-inhibitor direction for grass weed control in rice. In practical field terms, that means the formulation is built to stop the growth of susceptible grassy weeds after they have emerged. This is why the product fits post-emergence grass control so clearly.
Because both active ingredients are used in the same grass-control direction, the role of this formulation is not to cover every weed group in the field. Its role is to give rice growers a more focused option for annual grass weed management at the right post-emergence stage.
Why This Product Stands Out
Cyhalofop-butyl 12% + Metamifop 8% EC stands out because it gives you a very clear herbicide profile: rice crop, post-emergence timing, grass weed target. That makes the product easier to place in rice programs where the main weed pressure comes from grassy species rather than a mixed spectrum dominated by sedges and broadleaf weeds.
Another practical advantage is the formulation type. EC is a familiar finished-product format for rice herbicide supply and is easy to position in standard retail and distribution channels where customers already work with post-emergence rice herbicides.
Suitable Crops / Targets / Uses
The clearest crop direction for Cyhalofop-butyl 12% + Metamifop 8% EC is paddy rice. That is the strongest and most stable positioning for the page. The target weeds should also stay focused on the main direction of the formulation:
- Barnyardgrass
- Chinese sprangletop
- Crabgrass
- Goosegrass
- Other annual grass weeds listed on the local label
This herbicide is best suited to rice programs that need a grass-weed solution after emergence. It should not be presented as a general product for every weed situation in rice.
Application Guidance
Cyhalofop-butyl 12% + Metamifop 8% EC is a post-emergence herbicide. The use logic is simple: apply it when target grass weeds have emerged and are still at the proper treatment stage for rice-field control. Cyhalofop-butyl is specifically described as a post-emergence herbicide used mainly in rice, and research on rice grass control also shows that control becomes less reliable when weeds become too large.
Final dose, spray timing, water volume, and field-use direction should follow the approved local label and the local rice weed-management program. In fields with known resistance history, rotation and overall program design are important because resistance to ACCase-inhibiting rice herbicides has already been reported in some grass weeds.

Safety and Use Precautions
This rice herbicide should be used only in the approved crop direction and only at the proper weed stage. Good field timing is important because Cyhalofop-butyl 12% + Metamifop 8% EC is built for post-emergence grass control, not for late rescue treatment in overgrown weed situations.
Use appropriate protective equipment during handling and spraying, avoid drift to non-target plants, and follow the approved local label and local field-safety requirements.
