Is Talstar ok to use plants have been sprayed with horticultural oil or sulfur?
We would recommend doing the application of Talstar P before doing an application of horticultural oil or sulfur. This will provide the residual for the pests, and the other products will help with killing them as well. Spraying Talstar P over either one of these will likely decrease the effectiveness of the oil and/or sulfur.
