Cheetah, Tuscany


Cheetah is a quick, safe, easy way to manage resistance. Cheetah utilizes a novel mode of action to better protect crops from triazine, ALS, and glyphosate resistant weeds. It helps growers focus less on problems and more on profit.

For broad-spectrum, non-selective control of tough-to-control grass, sedge and broadleaf weeds, Cheetah is tough to beat. But sometimes great weed control is only half the battle. When the solution also needs to be long-lasting, growers can confidently recommend a tank mix of Cheetah and Tuscany.

Tuscany is proven, long-term protection, making it the ideal pairing for Cheetah. Tuscany provides long-lasting residual control of more than 90 weeds. Plus, it won’t leach or volatilize and delivers excellent rotational flexibility. 


Linex 4L

(509) 430-2299


As development of resistance weed populations is becoming more obvious each year, important weeds are gaining a
stronger foothold in potatoes grown in the Pacific Northwest. There hasn’t been a new herbicide mode of action introduced in the last two decades. The good news is that herbicide resistance can be delayed and even prevented while existing resistant populations can be controlled with proper planning.

NovaSource recently received a Special Local Need label for pre-emergence application of Linex 4L to potatoes in Washington and Idaho. This designation provides a mode of action previously unavailable for use in potatoes west of the Rockies at a much-needed time.

Although linuron, the active ingredient in Linex 4L, and metribuzin both inhibit photosynthesis at photosystem II, the chemical family and inhibition binding site are different. In addition, researchers have stated that substituted ureas such as linuron are not as prone to resistance as are traizinones. 

Linex 4L is known for having activity on nightshade, lambquarters, redroot pigweed, kochia and grasses.
