Effect of Residues of the Insecticide Levo Used to Control Pigeon Disease on the Systemic Nutrients of Palm Fruits

Abstract

The study aimed to estimate the pesticide residues used to control palm diseases in Muthanna Governorate (the insecticide Levo and its effect on the systemic nutrients in palm fruits). The results of measuring Levo pesticide residues used in controlling palm diseases measured by HPLC instrumental device showed that the highest concentration of Levo appeared in the spraying treatment after one hour, and the lowest concentration of Levo appeared in the spraying treatment after 120 hours, reaching (0.26, 0.00) ppm respectively. The results of the elements showed that the highest nitrogen appeared in the control treatment and the lowest rate in the pesticide Levo after an hour of spraying, which amounted to (0.28, 0.15), respectively, and for the phosphorous element, the highest appeared in the control treatment, and the lowest rate in the pesticide Levo after one hour of spraying. Spraying, which amounted to (0.045, 0.014) respectively, and the potassium element was the highest rate in the control treatment and the lowest rate was in the pesticide Levo after one hour of spraying, which amounted to (0.65, 0.42), respectively. While the calcium component had the highest rate in the control treatment, and the lowest rate appeared in the Levo treatment one hour after spraying, it amounted to (625.02, 589.47) respectively. And the magnesium element was higher in the control treatment, and the lowest rate appeared in the pesticide Levo after one hour of spraying, as it reached (314.88, 294.58), respectively.
