Well at least in the case of apples, before the advent of organophosphates, I believe many
were spraying something like lead-arsenate.
Good point, Chris. Knew there was something else I'd meant to mention, and that was it.
Lead arsenate(Paris Green) was used extensively in orchards - as well as in tobacco beds/fields here in KY - and I've seen cases of arsenic poisoning in cattle grazing in old, abandoned apple orchards where lead arsenate was used, probably decades earlier.
Nicotine sulfate was also used extensively, and I suspect many an orchardist probably got a racing heartbeat - and perhaps more than a few died - using the old "Black Leaf 40" extract, made from a strain of tobacco selectively bred for its high nicotine content.
