摘要
Blast disease (Pyriculariaoryzae) is one of the most important diseases of rice that can significantly reduce paddy production. This disease causes a potential loss of 3.65 tonnes/ha with loss percentages ranging from 60-100% if the disease is not handled properly. In spite of the issue of the negative effects of synthetic pesticide usage, the blast disease is commonly controlled using synthetic fungicides. Therefore, the exploration of potential botanical pesticides may provide safer and environmentally friendly blast disease management. This study aimed to test the potential of binahong plant (Anrederacordifolia) as botanical fungicide to inhibit the growth of P.oryzae and the development of blast disease in laboratory testing. The experiments were arranged in a Completely Randomized Design (CRD) consisting of 7 treatments of 5 extract concentrations and 2 controls. All treatments were repeated 5 times. The effectiveness of binahong leaf extract in controlling the pathogen and the disease was tested using poisoned food technique and detached leaf assay. The binahong leaf extract tested in the concentration range of 0.25-2% showed the ability to inhibit the growth of P.oryzae with the highest colony growth inhibition of 25.11%. Characteristics of P.oryzae mycelium and colony in the binahong leaf extract treatment were different from the control treatment. The treatment of paddy leaves with binahong leaf extract suppressed the blast disease development through the lessening of diseased paddy leaf area percentages. This study indicates the potency of binahong leaf extract for sustainable rice blast disease management.
