Test of the Vegetable Insecticide of Gadung Tuber and Babadotan Against Brown Planthoppers) on Rice Plants (Oryza sativa L.)

Abstract

The decline in rice productivity caused by WBC pests is a problem. However, the use of synthetic insecticides has a negative impact. Excessive synthetic insecticide control measures can cause losses, including environmental pollution, killing of natural pests, resistance and resurgence of pests, so using plant-based insecticides is an option because they are environmentally friendly and the ingredients are easy to obtain. The research used an experimental method in a complete randomized block design consisting of 4 replications of 6 treatments, namely: P1 = Gadung tuber extract 75 g/l, P2 = Gadung tuber extract 100 g/l, P3 = Gadung tuber extract 125 g/l, P4 = Babadotan Extract 450 g/l, P5=Babadotan Extract 500 g/l and P6=Extract Babadotan 550 g/l. The results of research on vegetable insecticides treated with gadung tuber extract 125 gr/l was 78.75%, Babadotan weed tuber extract 550 gr/l was 66.25%, gadung tuber extract 100 gr/l, Babadotan weed extract 500 gr/l was 58.75%. %, gadung tuber extract 75 gr/l amounted to 55% and Babadotan weed extract 450 gr/l amounted to 46.25%. These results cannot be said to be effective because the mortality value has not yet reached 80%.
