Wood Preservative Tests 



A recent report on tests at Cornell University, Ithaca, N. Y, 

 with wood preservatives for greenhouse flats indicates that it 

 is possible to increase the length of life of cheaper 'grades of 

 lumber and that the material tested, Cuprinol, had no adverse 

 effects on plant growth. Since some other preservatives contain 

 mercury and creosote have been observed to have toxic effects 

 on plants, Cuprinol was tested in closed chambers with plants 

 and found to be non toxic. 



In conducting the tests to determine the value in preserving 

 wood, flats were made of southern pine used in Florida orange 

 crates. The flats are given a quick dip after nailing and then 

 filled v/ith soil. The flats were then placed on rose benches, 

 and each time the rose beds were watered, the soil in the flats 

 also v/as watered, Other flats were handled in a similar 

 manner except they were not dipped in the wood preservative. 



At the end of the first year, the untreated flats were so badly 

 decayed that they could not be lifted. After two years, the 

 treated flats were reported as good as new except that many 

 of the nails had rusted and broken. 



We can furnish you Cuprinol at the following prices: 1 gal. 

 cans at $2.90 per gallon; 5 gal. pails at $2.80 per gallon; 50 

 gal. drums at $2.70 per gallon. 



Cuprinol covers and preserves approximately 400 square feet 

 of wood to the gallon (brush applied).
