Excellent insect growth regulator. Prevents insects and spider mites from molting from one stage to the next, so it interrupts the growth cycle and greatly reduces populations of mites and insects. I use every time I spray insecticides or miticides. Biggest difference has been in greatly reducing the number of mites in my garden of 250 dahlia plants.
