The intractable increasing cost of synthetic pesticides is certainly intense in the coming production years. Looking into this viewpoint the farmers have to look for alternative actions to withstand their farming business profitability. Rhizome crude extracts can be an alternative for synthetic pesticides. This study was conducted to assess the effect of rhizome crude extracts against glutinous corn seedling maggots, corn earworm, corn borer, armyworm, and aphids; evaluate the effect of rhizome crude extracts on the growth and yield of glutinous corn, and determine the profitability of glutinous corn production using rhizome plants as a source of organic pesticide. The treatments were as follows: T0 – No pesticide applied; T1 – Potable water alone; T2 – Ginger crude extracts; T3 – Turmeric crude extracts; T4 – Galangal crude extracts; and T5 – Shampoo ginger crude extracts. Results revealed that insect-pests and their damage on glutinous corn crop were significantly lessened by the application of rhizome crude extracts regardless of sources. This contributed to the significant stover yield and harvest index performance of treated plants with rhizome crude extracts thus obtained a profitable yield compared to those plants without any pesticide applied.
