Abstract: Resumo: Nos canaviais, espécies do gênero Euphorbia são relatadas como plantas daninhas capazes de reduzir a produtividade em até 85%. Para traçar estratégias corretas de controle dessas plantas é necessário o conhecimento tanto da sua biologia quanto do seu crescimento. Assim, objetivou-se com este trabalho avaliar o crescimento de três espécies daninhas do gênero Euphorbia ocorrentes nos canaviais. O estudo foi realizado em casa de vegetação, utilizando delineamento experimental inteiramente casualizado, em … Show more

“…One interesting pattern was that the most frequently collected weeds were several taxa of Euphorbia subgenus Chamaesyce, particularly Euphorbia hirta. This trend most likely reflects their wide climatic and edaphic tolerance, the fact that some of them feature C 4 photosynthesis, the numerous seeds produced by each individual, toxic latex that deters herbivores, and their resistance to pesticides (Ferreira et al, 2017;Tanver et al, 2013).…”
