The B&G AccuSpray Professional (24000100) is not made to be used with an extension wand; there would not be a way to attach the cable or the other end of the wand to the sprayer tank. The coil does reach up to 6 feet, and the tank will build up to 50 psi which can still spray several feet. We would recommend using a B&G 1 Gallon Sprayer if you need the extra reach of a wand. You could just mix less product at a time if your concern was wasting product.
RoundUp products should be mixed and applied in a gallon tank sprayer and shoud not be used with the B&G AccuSpray Professional.
According to the B&G AccuSpray Professional manual instructions, you can mix chemicals when using this sprayer. You want to follow the product label tank mixing instructions before to ensure they are compatable. Examples of tank mixing chemicals would be Talstar & ExciteR or Temprid & Gentrol IGR for crack and crevice applications inside the home along baseboards, windows, door entry points, under cabinets, around pipes, etc.
Mixing and Filling:
• Mix insecticides for the Professional ACCU-Spray in a separate container and then add 16 oz to the bottle.
