Assessment of Herbicide Residues in Different Varieties of Sugarcane Samples from Savannah Sugarcane Plantation, Numan L.G.A, Adamawa State, Nigeria

Abstract

The uncontrolled usage of herbicide residues in agricultural production can lead to the accumulation of chemical contamination in soil and plants. In this study, varieties of sugarcane samples were collected from three agricultural locations (Garisa, Kem and Pita 145) in savannah sugarcane plantation Numan Local government area Adamawa State. Five variaties of sugarcane samples was collected. Sugarcane samples were prepared using standard procedures. Herbicide residues, propachlor, atrazine, paraquat, propanil, alachlor, metolachlor and butachlor were determined using high performance liquid chromatography (HPLC). Results obtained from this study show that the sugarcane samples from the three agricultural locations contained some amounts of herbicides. There are significant differences in the mean concentrations of herbicides at the various sampling locations. Also, the concentrations of all the studied herbicides were significantly higher in the soil samples as compared to the sugarcane samples. Among the herbicide residues, paraquat was the most dominant in the study area, followed by butachlor. The study also revealed that most of the studied herbicide residues were significantly higher than the WHO and FAO maximum residue limits (MRLs) and acceptable daily intake values (ADIs) values.
