The Effectiveness of Natural Plant Powder in Controlling Rice Weevils (Sitophilus oryzae)

The rice industry today, very depends on synthetic pesticides to protect against losses. However, pose toxicity and give a negative effect humans, animals, the environment. Thus, this study aims observe effectiveness of natural powders such as neem ( Azadirachta indica ) black pepper Piper nigrum in controlling weevil Sitopylus oryzae during storage. Treatments included experiment comprised control where no plant powder was applied (T0), (T1), leaves (T2), combination with (T3). All treatments were conducted different types rice, Malaysia (local) Thailand rice. 30 g dosage for all 100 20 weevils introduced. laid out completely randomized design (CRD) 32 samples. finding shows significant (P= 0.000) weevil. Meanwhile, (T2) more effective storage due lowest survival rate (Local: 78.75%, Thailand: 55%) highest mortality 21.25%, 45%) both Besides, also showed damage data 20.75%, 20.35%) compared other treatments. Study findings can help meet current health, environment, safety standards.
