You may not be able to see what is lurking under the surface, but you can protect against it.
Rhizoctonia overwinters in the soil waiting to infect potato crops. Once the plant is infected, Rhizoctonia can cause all sorts of grief: slowed emergence, reduced stand and/or weakened plants. As the disease progresses, it can stunt growth, cause the formation of aerial tubers and even turn leaves a purplish color.
In recent trials at the Grow More Experience site in Ephrata, Washington, Syngenta potato seed treatments stood out in their ability to provide powerful protection against Rhizoctonia.
As seen in the trials above, CruiserMaxx Potato and CruiserMaxx Potato Extreme seed treatments with Elatus fungicide provided excellent control of Rhizoctonia. With its two-prong attack against soilborne diseases, Elatus adds a preventative component to help stop Rhizoctonia before it becomes a problem, ultimately resulting in improved potato emergence, more uniform crop stand and enhanced crop health.

Growers should be aware that MRLs in export markets outside of North America are lower than those in the United States and may not be high enough to cover residue on all potato products. Prior to Elatus application, growers are advised to check with their potato buyer regarding Elatus use.
