comportamento do herbicida em laboratório

Abstract

Action of Trifuralin on some biology's aspects of freshwater Planarian Dugesia tigri-na, Girard, 1850. Behavior of the herbicide in laboratory. 'Iwo groups of freshwater planarians Duge-sia tigrtna were compared in respect of some features of their biology concerning to reproduction. One of the groups had been kept for only once in 2 and 3 mg/1 of Trifuralin solution during 96 hours and the other had never been in contact with that substance, experimemaly. Some considerations about properties of that herbicide could be inspired from the results of the research.
