I don't understand how you all got certified and don't understand looking at a label to identify the type of product you are using and if it needs agitated once or constantly, and if it can be stored mixed. I would love to give you a sample of some wetable powders to throw in your tank once. Or some nasty emulsion for you to let sit a few days in your equipment. If you think I am harsh well I am. You should know this stuff like 101. Pesticide Formulation 101.
