Daryl, I will not disagree with you on it being illegal to use diesel fuel as a stand alone herbicide. I will admit that I can't quote the law on it and I have made some enquiries about it and should know something before long. You have tweeked my interest on this issue and will pursue it until I have some answers and if I'm wrong, I'll let ya know. ;-) However, I do know that it's perfectly legal to use diesel as a surfactant and/or emulsifier here in Texas. These are common practices here for brush control and insect control (mesquitos and flies). I've used diesel, in the manner I described previously, most of my life. I'm not saying that this is justification, but when used in a common sense attitude, as with all chemicals, it is very affective. And as I've stated before, you have tweeked my interest and I'm interested in knowing exactly what the law says because I don't believe it is completely illegal to use diesel and am interested in knowing where they draw the line for private use and property rights. I do agree that diesel can be "incredibly" toxic when not used properly. The laws that were developed were probably more aligned with stopping folks like the Railroads and highway departments from washing their right of ways with diesel. But, too much of anything can be incredibly toxic. And I believe that in the case of my own folks, I'd rather see diesel in their hands than to think of the damage they could do with something such as Roundup or gasoline. I have spent several years doing PST (petroleum storage tank) work and know that gasoline is several times worse than diesel when it comes to the environment. Unfortunately, I wasn't consulted before the application event with Roundup or I'd've recomended something other than Roundup, such as Brush B Gone, or would have at least advised waiting until this winter to start acting against the stuff with mechanical removal then treatment. I try to stear away from chemical treatments if mechanical treatment can be accomplished.
