Abstract: (406 Views) |
The use of ornamental flowers in urban green spaces is extensive across different seasons and inseparable from contemporary urban management. The periodic application of pesticides in urban environments is common to maintain the aesthetic appeal of various plants and ensure citizen satisfaction with urban management activities. The cabbage aphid is a significant pest in urban green spaces during the winter, causing economic damage and transmitting viral diseases by feeding on plant sap if left uncontrolled. This study evaluates the lethal effects of different concentrations of two botanical compounds, Diabon and Melia azedarach L. extract, alongside the chemical pesticide abamectin, compared to a control treatment (water) on the population control of cabbage aphid on ornamental cabbage. Treatment efficacy was assessed by sampling and comparing the aphid populations on ten selected leaves from ten ornamental cabbage plants at intervals of seven, fourteen, and twenty-one days after spraying. The results indicated that the abamectin treatment (8.44 ± 2.9) was effective in controlling the cabbage aphid population. Following this chemical pesticide, the botanical pesticides Diabon at a concentration of 8000 ppm (1.8±0.72) and M. azedarach extract at concentrations of 4000 ppm (4.83±1.2) and 8000 ppm (4.66±1.3) were also effective in reducing the cabbage aphid population during the initial seven days and can be used in integrated pest management.
