For Use In

Bromacil/Diuron 40/40 is a selective herbicide for use in citrus and in non-crop areas. Bromacil/Diuron 40/40 controls many annual weeds at lower rates and perennial weeds at the highest rates allowed by this label.


For control of annual and perennial weeds apply Bromacil 40/40 at a rate of 2lbs per acre. Apply using a properly calibrated fixed-boom power sprayer. Use sufficient spray volume, a minimum of 10 gallons per acre, to provide uniform coverage of the treated areas and to allow proper dispersion and suspension of the product in the spray tank.

Prior to and during application, continuous agitation is necessary to keep the product in suspension. Agitate spray tank contents by mechanical or hydraulic means; do not use air agitation. Note: if a by-pass or return line is used, it should terminate at the bottom of the tank to minimize foaming.

Best results are obtained if Bromacil/Diuron 40/40 is applied to bare ground. If dense populations of hard-to-kill weed species are present, control of these weeds prior to application of Bromacil/Diuron 40/40 is recommended. If weeds are present at the time of application, tank mixtures with foliar active herbicides are recommended (refer to the tank mixture specific guidelines section of the label for guidelines on using Bromacil/Diuron 40/40 in a tank mixture).

Is Bromacil 40/40 available in smaller that 6lb. bags? Use is for a gravel parking lot.
Ron on Feb 19, 2017
BEST ANSWER: Hi Ron, Bromacil 40/40 only comes in a 6# or 25# bag. The manufacturer does not make a smaller bag since their main customer for this product is the railroad companies spraying miles of tracks.
