Drop the paraquat. That much paraquat antagonizes glyphosate. If you want to use paraquat, omit the glyphosate. The diuron in the Krovar will modify the action of the paraquat, making it a much more potent herbicide.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
