I'm not sure it's any cheaper than Raptor. Am I misunderstanding something on the label?
The average ounce-per-acre of Raptor is around 3oz. The absolute highest rate shown on the Raptor label is 8oz for volunteer corn, but for most weeds 3 to 5 oz per acre is the average.
And Keystone is selling the Imox... by the quart @ $97.95. ($400 gallon)
Clearcast is $300 per gallon ($75 quart) but it's label shows roughly the same oz per acre as Imox. Looks like Clearcast is actually cheaper per acre.
I didn't do all the math, but it looks like when broken down to cost per acre, Raptor is the cheapest. Am I missing something?
BTW, I've been using the same gallon of Raptor for several years...a gal goes a loooong way, but I'm not exactly crazy about the results.
If you don't put chicory in your plot, then I see no reason why 2,4-DB, and/or cleth can't handle most weed issues in a clover plot with better results and less residual than Raptor.
