What affect does pH of the spray solution have on EverGreens performance?
A. The pH of the spray solution is very important! It is vital that the spray solution is buffered to a pH of 5.5 – 7.0. Application of a spray solution with a pH outside of this range will most likely result in poor efficacy on target pests. If the solution is outside of this pH range, the pyrethrins will degrade.
