IPBC - A new fungicide for wood protection
1984 - IRG/WP 3295
3-iodo-2-propynyl butyl carbamate (IPBC) is presented as a potential low toxic alternative to pentachlorophenol and the sodium chlorophenoxides. Data on its effect against basidiomycetes is shown. Tests according to both the European standard method, EN-113, and American, ASTM D-413, have shown its potential. The chemical gives protection against both the wood destroying fungi, blue stain, mould and algae. It is possible to have it formulated in both water-based and organic solvent-based products. Treatment of wood out of ground contact (vac-vac products, pretreatment products, primers, stains, etc.) and sapstain control are some of the most potential end use areas within wood protection. Besides wood protection, the IPBC is used as a fungicide in paint, adhesives, caulks and sealants, cement, leather, paper, cutting oil, ink and in different roofing materials.

Field evaluation of alternative antisapstain chemicals
1982 - IRG/WP 3198
Seven alternative antisapstain formulations containing four different active ingredients were field tested during the summer and fall of 1981. The test was designed to evaluate the potential long term effectiveness of PQ-8 (Chapman Chemical Co.) containing copper-8-quinolinolate, Busan 30 (Buckman Laboratories) containing 2-(thiocyanomethylthio)benzothiazole, BL2398 (Buckman Laboratories) containi...
