Description
Carbaril behaviour is studied in samples of Brunizen and Dark Red Latosol soils from Parana, using radiometric techniques, with the objective of determining the role of oxidation fo its organic components, and enrichment with glucose, in the metabolism of the insecticide. Lots of autoclaved soils, oxidized and with no previous treatment, with and without glucose addition, are incubated with 14C-carbaril and analysed during eight weeks. Its was noted that, as a result of oxidation both soils showed a marked improvement in the metabolism of the agrochemical while addition of glucose exerted litlle influence on the degrading processes. Three metabolites were detected with R sub(f) 0.23, 0.40 and 0.70. (Author)
Abstract (Portuguese)
Estuda-se o comportamento do carbaril por meio tecnicas radiometricas em amostras de solos Brunizen e Latossolo Vermelho Escuro do Estado do Parana. Objetiva-se definir o papel que a oxidacao dos seus componentes organicos e o enriquecimento com glicose tem no metabolismo do inseticida. Lotes de solos autoclavados oxidados e sem tratamento previo, com esem adicao de glicose, foram incubados com carbaril-14C e analisados durante oito semanas. Constata-se que a oxidacao proporcionou em ambos um incremento acentuado no metabolismo desse defensivo agricola, ao passo que a adicao de glicose teve pouca influencia nos processos degradativos. Detectou-se tres metabolitos com R sub(f) 0,23, 0,40 e 0,70. (Autor)Files
