Effect of the addition of carbon sources on the carbaryl degradation in soils

Description
Using liquid scintillation counting, the degradation of carbaryl was investigated in two types of soils to which several sources of organic nutrients were added. Results showed that after 6 week treatment, degradation of carbaryl, under the influence of carbon sources except cellulose and filter paper, increases in the yellow red latosol soil where all the insecticide was totally degraded, as compared to the humic gley soil. Additions of plant leaves and filter paper with or without previous incubation during 2 weeks, similarly changed the persistence of carbaryl in both soils. (Author)
Abstract (Portuguese)
Investigou-se a degradacao do inseticida carbaril em dois solos tratados com diferentes fontes de nutrientes organicos, utilizando-se tecnicas radioisotopicas de cintilometria em liquido. Resultados obtidos mostram que apos seis semanas de tratamento a degradacao do carbaril, sob a influencia das fontes de carbono exceto celulose pura e papel de filtro, aumentou no latossolo Vermelho-Amarelo onde todo inseticida foi degradado, comparando ao solo Glei Humico. O tratamento com folhas de vegetais, com ou sem incubacao previa por duas semanas, modificou de modo semelhante a persistencia do carbaril em ambos os solos. Comportamento analogo foi observado usando-se papel de filtro, que e fonte de carbono de metabolizacao mais lenta. (Autor)Additional details
