I assume that FevaStar can be mixed with Gentrol as Temprid, but wanted to inquire prior to doing so. Appreciate your help. Also, do you find that alternatating chemical sprays can prevent the insects builidng a tolerance to one chemical?
Yes it is absolutely fine to mix Gentrol with the FenvaStar, Temprid, and any other insecticide on the market. IGR's are specifically designed to be safely mixed with concentrates without causing any effect to the product being used. Yes, alternating sprays every couple of months will help you prevent a resistance but just changing the name of the chemical is not the key. You must change the type of ingredient being used, example: Suspend SC contains Deltamethrin, Talstar P contains Bifenthrin, and Demon WP contains Cypermethrin. While all the products are different names, and the active ingredients are different, all of the active ingredients fall into the Pyrethroid category of type of chemical base. In order to prevent a resistence, you would need to find a product that you alternate with any of those that is not a pyrethroid.
