Barbara from Sebastian, Fl writes
I purchased the auto mix sprayer how much do I need for white flies? How will I know when it is no longer in the sprayer? What setting should I use?
To treat ornamental plants for whiteflies, you can use 0.26 – 1.28 oz of Bifen XTS per 10 gallons of water, per the product label. The rate at which you set your hose-end sprayer will depend on what settings are available, although this is a pretty low rate per gallon of water with the highest rate being 0.128 oz per 1 gallon of water. 1 gallon of water usually treats about 1000 sq ft of turfgrass, so it will likely treat less area if you are treating dense ornamental growth. Be sure you are treating all the leaf surfaces until they are wet but not to the point of runoff.
