Incorporating lemon grass (Cymbopogon citratus L.) and marigold (Tagetes erecta L.) as non-host barrier plants to reduce impact of flea beetle (Chaetocnema confinis C.) in cabbage (Brassica oleracea var. capitata L.)

The repelling of insect pests and attracting beneficial insects using non-host plants is an important component ‘push-pull’ strategy. Plants with insecticidal properties are locally abundant can be utilized to management pests. For this study, Lemon grass (Cymbopogon citratus L.) Marigold plant (Tagetes erecta were intercropped cabbage (Brassica oleracea var. capitata as border reduce the population dynamics flea beetle (Chaetocnema confinis C.). was selected based on its repellent while marigold for pull mechanism. Both lemon planted barrier or cabbage. (C. citratus) effective in minimizing abundance C. confinis, reduced defoliation (%) enhanced leaf area (p
