Herbicide Groups

Importance of Mixing and Rotating Mode of Actions
New herbicide modes of action have been discovered in the past 30 years.

With the outlook for new MOA bleak, we need to look after the herbicides we have. 

It is critical to both mix and rotate herbicide MOA’s. For example, if trifluralin is applied once in every 3 years in rotation with other herbicides, one of the herbicides fails within about 11 years. However, using trifluralin in 2 out of 3 years, when mixed with Sakura® or Boxer Gold®, will double the time before one of the herbicides fail. 1
