Ivan from Cutler Bay, Fl writes,
Can Gentrol IGR and Bifen IT be mixed together?
Absolutely. Gentrol IGR can be mixed with any insecticide concentrate and be applied at the same time, including Bifen IT. However, when mixed with an insecticide concentrate like Bifen IT you are limited on where you can apply the Gentrol IGR since you can only spray in areas where the Bifen IT is permitted to be applied according the label instructions.
