Boracure PROVED EFFECTIVE by independent N.Z. Scientist * * , V f \ * See 'Tests with Timber Preservatives in New Zealand", by J. M. Kelsey—The N.Z. Journal of Science & Technology, Vol. 27. May 1946, P. 446. Write to Boracure for reprint. Once again science justifies the use of Boracure. In tests of various .wood-treating preparations, entomologists of the Department of Scientific and Industrial Research demonstrated that Boracure’s oil-soluble toxic (Pentachlorphenol) was entirely effective in the control of wood-boring insects. In these tests, which covered several years' investigation, specimens of timber I; were impregnated with various oil-soluble and water-soluble toxics and subjected to borer attack. Pentachlorphenol came through with flying colours. For instance, EGG LAYING TESTS WITH PENTACHLORPHENOL .Pentachlorphenol treat.-, ed blocks had NO EGGS iifclef-ort them m any tests and beetles themselves died In', a shorter time than when in the presence of water soluble test specimens. Even untreated control blocks had no eggs laid on them when used in tests near pentachlorphenoltreated blocks. > r WITH WATER SOLUBLES Eggs were laid almost as freely on blocks treated with water soluble toxics as on untreated control blocks alongside. Beetles did not die, eggs hatched and grubs lived for a considerable time. Placing untreated control blocks alongside those treated with water solubles did not prevenC profuse egg laying on controls during tests. Pentachlorphenol proved to be extremely toxic to Borer insects which died without laying eggs —even on untreated timber in the same cage! LARVAE TESTS SiSii were placed in holes bored in blocks each of which was treated a different woodpreserving chemical. Eight months later the block's were split open. In PENTACHLORPHENOL TREATED BLOCKS ALL THE GRUBS WERE DEAD, which was not so with many other toxics# BORACURE FOR RESULTS! Insist on genuine Boracure treatment. All Boracure men have an identifying lapel badge incorporating the "Spray Man.” m B zsm ■ CHRISTCHURCH BRANCH: 122 A MANCHESTER STREET, CHRISTCHURCH; 'PHONE 36-016. fiiiuiuiiiiiiiiiiiiiiiiiiiiiiifiiiiiiiEniiiiiiiiiiiiiuiiiiiiiiiiiiimiiiiiiiTniiiuiiiiiiiiHiiiiiiiifiiiiiiiiiiiiiiiiiiiiHiiiiiiiiiiiiiiuiiim^ Railage on Lime As from MONDAY, OCTOBER 13, the SUBSIDY on LIME HAS BEEN REMOVED, and Farmers are now required to pay Railage from Lime Works to Nearest Station.
