From our collection of old pesticide and fertilizer labels, here are a few "Old Timers".  The oldest of these is Michel & Pelton Company's "Whale Oil Soap" which we think dates from before the early 1940's, possibly as early as the 1920's. Whale oil was commonly used both as an insecticide and also as a spreader for chemicals like lead arsinate and nicotine sulfate.  This one and the Red Arrow Spray (pyrethrin) label were aquired (with permission) from the pesticide shed of a flower nursery which was located in San Leadndro, California.  The other labels date from the 1950's and into the 1970's.
