A total of 10 proprietary and two experimental formulations were assessed for their effectiveness against sap-stain caused by Botryodiplodia theobromae on Rubberwood (Hevea brasiliensis). Sterilized wood samples 5x20x40 mm³ were dipped in the test chemicals for 60 seconds and then inoculated with 0.5 ml of culture filtrate of Botryodiplodia theobromae for incubation in sterile, damp petri dishes. Two formulations, Kemicide 1009 and stainguard gave good control at 1% strength while the experimental formulation ES AS11, was effective at 0.05%. NP-1 was effective at 1.0-2.0% while TBP gave some control at 3%.
