Customizable, Effective Weed Control

Any successful residual herbicide program for rice should be customized to address weeds in your specific growing environment and should start earlier than later — much earlier. The larger weeds become, the more difficult and costly they are to control. Clincher® SF herbicide delivers early postemergence control of ALS-, propanil- and quinclorac-resistant barnyardgrass. For weed control post-flood, turn to RebelEX®, a herbicide with dual modes of action for consistent control of sprangletop, barnyardgrass, broadleaf weeds and aquatics. This broad-spectrum weed control is a herbicide solution that fits into all crop systems. 

Flexibility and Convenience

Clincher® SF herbicide can be tank-mixed with other residual herbicides offering rice farmers more flexibility and convenience when implementing early season weed control programs. Clincher SF herbicide also eliminates rotational restriction concerns, an invaluable asset when making crop rotation decisions for the next growing season. RebelEX® herbicide gives you a 60-day preharvest use window and will not injure rice when used as labeled. The two modes of action in RebelEX herbicide provide flexibility in your efforts to preserve chemistries through improved resistance management.


U.S. farmers have a long-standing reputation of providing a safe and reliable source of food and fiber to the world. That reputation was built on their commitment to stay on a path of continuous improvement. Farmers are the world’s front-line environmental stewards. They understand the importance of protecting the environment and preserving its natural resources because they not only work the land each growing season but also many of them raise their families on it.
