Carol from Tarpon Springs, Fl writes
I have a severe infestation of chinch bugs in my 1500 sf St. Augustine lawn. I sprayed at 1 oz per gallon and then handwatered in. I am concerned that I applied too much water...how do you know that the product is not being diluted too much? Also if I sprayed 3 days ago can I water in fertilizer now without making the Bifen less effective?
As long as Bifen IT was applied as directed on the label and watered in as required for chinch bugs (at least 0.25 inch of irrigation) after application, you can go ahead and water in the fertilizer. It will not move much farther into the soil as it is designed to bind to the soil. If more water was used that would just have pushed it down into the soil better and will be fine.
