Resumos

Experimentos de campo e bioensaios em casa-de-vegetação foram realizados para se estudar a influência da cobertura morta de trigo (Triticum aestivum L.) no comportamento dos herbicidas imazaquin {ácido 2-[4,5 dihidro-4-metil-4-(1-metiletil)-5-oxo-1H-imidazol-2-ilo]-3-quinolinacarboxílico} e clomazone {2-[(2-clorofenil)metil]-4,4-dimetil-3-isoxazolidinona}, aplicados em pré-emergência na cultura da soja [Glycine max (L.) Merril], no sistema de plantio direto. O clomazone mostrou evidências de ter sido interceptado pela cobertura morta. A presença da cobertura morta não influiu na retenção do imazaquin, sendo este lixiviado da palha para o solo com as chuvas que ocorreram após a aplicação.

Field experiments and glass house bioassays were conducted to determine the influence of winter wheat (Triticum aestivum L.) straw mulch on the behaviour of the herbicides imazaquin {2-[4,5-dihydro-4-methyl-4-(1-ethyl)-5-oxo-1H-imidazol-2-yl]-3-quinolinecarboxylic acid} and clomazone {2-[(2-chlorophenyl)methyl]-4,4-dimethyl-3- isoxazolidinone}, wich had been applied to pre-emergence soybean (Glycine max)in a no-till system. There was evidence that clomazone had been intecepted by the straw whilst imazaquin was leached into the soil by rain.

ABSTRACT

Field experiments and glass house bioassays were conducted to determine the influence of winter wheat (Triticum aestivum L.) straw mulch on the behaviour of the herbicides imazaquin {2-[4,5-dihydro-4-methyl-4-(1-ethyl)-5-oxo-1H-imidazol-2-yl]-3-quinolinecarboxylic acid} and clomazone {2-[(2-chlorophenyl)methyl]-4,4-dimethyl-3- isoxazolidinone}, wich had been applied to pre-emergence soybean (Glycine max)in a no-till system. There was evidence that clomazone had been intecepted by the straw whilst imazaquin was leached into the soil by rain.

Additional index words: no-till, soybean, Glycine max.
