Técnica de cruzamentos controlados em Euphorbia heterophylla L. [PDF]

Bragantia, 1999
O leiteiro, Euphorbia heterophylla L., é uma planta daninha comum no Sul, no Sudeste e no Centro-Oeste do Brasil. Seu controle químico é realizado principalmente com herbicidas que agem inibindo a enzima acetolactato sintase. Contudo, nos últimos anos, vêm sendo observados genótipos resistentes em diversas lavouras da região Sul.
