The paper presents an unprecedented study of evaluation of preservatives’ phytotoxicity used in the treatment of bamboo and usually discarded on soil. Three preservatives were evaluated, one of them unpublished, using a simple, low-cost and effective analysis technique. All preservatives were shown to be very phytotoxic even at high dilutions in relation to the concentrations usually used in bamboo, compromising both germination and root development. Thus, the disposal without treatment in the soil will cause risks to the vegetation.
