EDITORIAL NOTE ABOUT INSECTICIDES
Recommendations given in previous editions of this book regarding use of DDT and other “hard” pesticides are withdrawn in this 12th edition. We advise, until questions about merits and dangers of these products are resolved, that you contact a local agency before deciding what pesticides, if any, to use.
We believe that every citizen should make a real effort to become informed about pesticides and potential changes in them, for use or non-use will likely have great impact on mankind’s future use of this earth.
