Resumo - 

Com o objetivo de verificar o efeito de baixas doses, simulando a deriva do herbicida glyphosate no crescimento e desenvolvimento inicial da Commmelina benghalensis foi realizado um  trabalho  em  condições  de  casa-de-vegetação.  A  trapoeraba  foi  semeada  superficialmente (aproximadamente  2  cm)  em  tubetes  preenchidos  com  substrato.  Após  a  germinação,  deixou-se apenas  uma  planta  por  tubete  e  realizou-se  aplicação  dos  tratamentos.  Os  tratamentos  foram constituídos por diferentes doses de glyphosate, 2, 4, 8, 16, 20 e 24 g e.a. ha-1 e uma testemunha sem aplicação. Pelos resultados obtidos pode-se verificar que em geral, doses a partir de 2 g e.a. ha-1 podem causar efeitos no crescimento e desenvolvimento da parte aérea e radicular de plantas de C. bengalensis.

Abstract  -  

With  the  objective  of  verifying  the  effect  of  low doses,  simulating  glyphosate herbicide  drift  in  growth  and  initial  development  of Commmelina  benghalensis,  a  study  was conducted  in  greenhouse  conditions. C.  benghalensis  was  superficially  sowed  (approximately  2 cm) in small tubes filled out with substratum.  After the  germination,  just  one plant by tube  was kept and treatments  were applied. Treatments were constituted by different  glyphosate doses, 2, 4, 8, 16, 20 and 24 g a.e. ha-1 and a check without application. By obtained results, it was possible to  verify  that,  doses  starting  from  2  g  a.e.  ha-1  may  cause  effects  in  growth  and  development  of dossel and roots of C. benghalensis plants.
