Butyrac 200 spot spray

See post #12 in "Spraying weeds in Clover plots" for more info on this;
Butyrac200 When using hand sprayers mix 1/4% to 1/2% (0.33 oz. to 0.65 oz. per gallon) Butyrac200 and treat to wet vegetation, while not allowing runoff of spray solution. Include crop oil concentrate at 1% (1.3 oz. per gallon) by volume.
However, I often do more like 2-4 oz per gallon for spot spraying.
