Check out the Newsletter for a Steve-suggested download about pesticides. It's from Franklin county and Steve says "This guide provides the recommended insecticide active ingredient(s) for the most common insects and mites AND some brand name products that contain them.
There are four sections in this guide; general landscape pests, specific pests of trees and shrubs, annuals and perennials, and insecticide tables that list active ingredients and brand name products. The "General Use Pesticides for Home Lawns" is also available and is a similar format."
