    This study was conducted to determine the efficiency of seven antisapstain products that are sold in Mexico to control the fungus that stains Ceratocystis sp. on lumber of rubber (Hevea brasiliensis), by means of the method of the disks jointly with the norm ASTM D 4445-91. Three of these products, Osmotox, Pentatox and Biotox, are made from sodium-pentachlorophenate, three more are made of methylene-bis-thiocyanate and 2-thiocyanomethylthio benzothiazole: Busan 1009, Busan 1450 and Busan 1071, and the seventh, Busan 1118, only contains 2-thiocyanomethylthio benzothiazole. The minimum effective concentration needed to prevent sapstaining for a four-week exposure to the chemicals was estimated to be 4.68 % Osmotox, 2.82 % Pentatox, 3.24 % Biotox and 2.00 % Busan 1118. In contrast, no sapstain occurred with methylene bistiocyanate and 2-thiocyanomethylthio benzothiazole, even with the smallest tested concentration; it is estimated that the concentration required is less than 0.25 %. Considering the commercial cost of each product and the lowest effective concentration for zero growth, Busan 1071 is the most economical and effective product.

    Keyworks: preservation, sodium pentachlorophenate, methylene-bis-thiocynate, 2-thiocyanomethylthio benzothiazole.
