Valor use in Dry Beans

Question: I heard yesterday Valor does not have a dry bean label for ND anymore but OK in MN though. What am I missing here Rich?

Answer: I can see why there is confusion. Valor and Spartan are related herbicides. They have the same mode of action and have a similar weed spectrum of control. Back in the late 90s early 2000s I worked with Valent to find a way to get adequate Valor safety on dry beans. Valent even tried reformulating the herbicide several ways to make it safer and nothing worked. The soils in this region for some reason make it too active and we gave up on it and Valor was never labeled on dry beans in the entire mid-west. Researchers out west did studies on dry beans and found better safety but still some risk of injury to dry beans. Valent developed a supplemental label allowing use only in CO, OR, and WA: http://www.cdms.net/LDat/ld3LL038.pdf

The herbicide for dry beans in ND and MN is sulfentrazone - the active ingredient in Spartan Charge/Spartan Elite…..and nary should they be confused with Valor.

To my knowledge, Valor is NOT labeled in MN on dry beans nor any other state in the mid-west.
