I understand that its not possible to put absolutely every possible susceptible weed on the label. But, that label is a good indicator of what economically important weeds may be controlled. With KRBS being such an economically important problem, it would stand to reason that if a product actually controlled it, the manufacturer would want to put that information on its label. If an economically important weed is not on a label, it may be a good assumption that a particular product won't have the desired effect on that weed. The bottom line is that I see guys sink a lot of money and time into different witch's brews that don't give them much efficacy. Instead of sending someone down a rabbit hole chasing expensive options with little more than a prayer to use as evidence, I like to rely on solid evidence. With all the scientists and resources that chemical manufacturers and universities have working on just this one particular issue, I don't think that many guys on this board are going to magically come across something effective that hasn't already been tried. And if it has been tried and is effective, do you think any of the manufacturers would miss the opportunity to sell it?
