PENAMBAHAN DEKOMPOSER SEBAGAI BAHAN STIMULATOR UNTUK MENINGKATKAN EFEKTIVITAS PESTISIDA NABATI

Abstract

Addition of Decomposers as Stimulators for Increasing the Effectiveness of Vegetable Pesticides. This study aims to determine the increased effectiveness of plant-based pesticides added with several types of decomposers. This study uses a Completely Randomized Design (CRD), with 5 treatments and 5 replications namely: FO: Control (water), F1: Plant pesticides without the addition of decomposers, F2: Vegetable pesticides + EM-4, F3: Vegetable Pesticides + Promi, F4 : Vegetable Pesticides + rice washing water. Observation variables consisted of mortality of contact poison, stomach poison, Lethal Time (LT 50%) and the speed of death as well as the attitudes and eating behavior of Parmarion martency. The results showed an increase in the effectiveness of plant-based pesticides that were significantly different from the control but not significantly different in each treatment where F3 treatment increased mortality by 0.05% (contact poison) from pesticide extracts without the addition of decomposers while the effectiveness of stomach poison only increased by 0, 14%. The fastest 50% lethal time in F3 treatment with 50% LT period was 48.4 hours with a mortality rate of 0.8 hours / individual in contact poison and 50% LT in stomach poison for 52.0 hours with a death rate of 0.6 hours /individual. Changes in behavior due to contact poisons are characterized by releasing grayish white fluid and then death is characterized by a rigid body that is easily reversed, and stomach poisoning behavior is characterized by experiencing less active, being in one place and dying in reverse.
