Tóm tắt
Chủ đề

The cabbage webworm Hellula undalis Fabricius (Pyralidae:Lepidoptera) is a serious insect pest on green mustard (Brasica juncea L.). This study was to evaluate the efficacy of the extract from Pongam leaf (Pongamia pinnata L.) for the control of the cabbage webworm in the laboratory. The results shown that the extracts were high efficacy against the cabbage webworm. Seventy two (72) hours after treatment, the efficacy was highest (88.2 - 91.3 percent) treated with the extracts in the concentrations of 80 - 100 percent. Further field evaluation is necessary in oder to determine appropriate concentrations of the leaf extracts to control the cabbage webworm as a botanical insecticide to reduce chemical use in safe vegetable production.
