Abstract
ABSTRACT Brown planthopper (Nilaparvata lugens) is a type of pest found on the padimeru plant that can damage rice by sucking the rice liquid, causing the rice plant to dry out like a burn. One of the efforts made to reduce the spread of pests is by using vegetabel pesticides. Guava leaves (Psidium guajava L.) have very high antioxidant and antimicrobial content to be used as an alternative to natural pesticides. Compounds in guava leaves contain saponins, flavoids, tannins, terpenoids and alkaloids that can inhibit the spread and population of the brown planthopper (Nilapavata lugens). This study aims to determine the effect of guava leaf extract (Psidium guajava L.) on the death of brown planthopper (Nilaparvata lugens) in order to provide information to the public that guava leaf (Psidium guajava L.) can be used as a natural pesticide. This study is an experimental study with a completely randomized design (CRD) with 5 treatments and 5 replications. The sample used was brown planthopper (Nilaparvata lugens) with P0 DDT (100 ml), P1 (1%), P2 (1.5%), P3 (2%) and P4 (2.5%). Observations were made for 24 hours at a concentration of 1% the average dead brown planthopper reached 36%, the concentration of 1.5% reached 56%, the concentration of 2% reached 80%, the concentration of 2.5 reached 100%. Based on analysis of variance (Ansira) showed that guava leaf extract (Psidium guajava L.) had a very significant effect (p> 0.01) on the mortality of brown planthopper (Nilaparvata lugens). The effective concentration to kill the brown leafhopper (Nilaparvata lugens) is 2.5% concentration. Keywords: Guava leaf extract (Psidium guajava L.), Vegetabel peptides, Brown planthopper (Nilaparvata lugens)
