Are their any other formulations you would not recommend using unless you can properly agitate? What is the best formulation for minimal agitation?My opinion is that ester formulations that form a milky solution--do have a tendency to settle out. I think I killed some grass that way using the solution after it sat overnight in my Permagreen.
Three-way products seem to work fine. A bit of recycle of excess flow should work as adequate agitation. It is a good idea to run the pump for 60 seconds when first starting out in the morning to make sure it is well mixed.
DA, luckily I haven't - at least not yet. I'm just preparing to get into a good bit of spraying this spring and I want to know as much as possible to reduce mistakes.OP I assumed you used all of your mix same day. Leaving mix sit in the tank too long is never a good idea.
