Efektivitas Bioinsektisida Daun Eceng Gondok (Eichhornia crassipes) Terhadap Kematian Ulat Grayak (Spodoptera litura) Dan Biomassa Bayam Merah (Alternanthera amoena Voss)

Abstract

The application of vegetable insecticides derived from water hyacinth leaf extracts was used to determine the mortality rate in armyworms on red spinach plants. The analysis observed from the number of leaves and production of red spinach plants, natural insectide treatment used concentrations of P0 (0%), P1 (5%), P2 (10%) and P3 (15%). The research analysis used a completely randomized design (CRD) with 4 treatments and 6 replications, the data obtained were analyzed using the ANNOVA test and the Duncan test. The results showed that presenting a plant-based insecticide on water hyacinth leaf extract had a significant effect (P <0.05) on the number of armyworm mortality, red spinach plant growth (number of leaves) and production of red spinach. The results of the Duncan test analysis showed that the P3 treatment (15%) was significantly different from other analyzes.
