Just a bit of thought on an otherwise nasty day.... Cleaned out a bookcase that had not been touched since we moved here six yrs ago. Mainly I found most of my Grandmothers old Gardening books. One I found rather interesting. It is "Sunset Flower book", Lane Publishing Co. Circa 1947, first edition. All pics are pen and ink drawings - if there are any. Most plant info is probably still pertinent, such as planting times. Seasonal to-do list, propagating, pruning, general characteristics of plants, and so on, but the pest controls (I assume) are mostly forbidden now. The list contains such names as Nicotine oils, Rotenone, Double Action (pyrethrum & rotenone),Derris resins, Petroleum oils, Ethylene glycol oleic ester, Pine-tar acids, Ethylene dichloride, Copper, and DDT, Lead arsenate dust, & the toungue twister Paradichlorobenzene. Some of this stuff may be fine, but it sounds lethal. I don't even pretend to know what some of this stuff is but it all sounds horrid. And to think it's been put into out soils and has spread to heaven knows where. Times and tides do change, and we have made some progress by getting some of this stuff off the market!!!
