Serangan Virus Kuning Terong pada Induksi Ekstrak Daun Clerodendrum japonicum dan Mirabilis jalapa

Abstract

The main problem of eggplant cultivated was yellow leaf virus disease. It has caused production of eggplant decreased significantly. Control of eggplant yellow leaf virus disease are effective, cheap and easy were used of resistant varieties. There was no eggplant varieties were resistant to eggplant yellow leaf virus disease. The resistant of plant has actived with an inducer agent of systemic resistance.The aims of the research were to study the effect of induction of Clerodendrum japonicum and Mirabilis jalapa leaf extract on eggplant yellow leaf virus disease, and to study interaction between eggplant varieties and induction of leaf extract on eggplant yellow leaf virus disease.This experiment used Factorial Randomized Complete Blocks Design (RCBD) which consist 2 factors, first factor was eggplant varieties: green and purple. Second factor was induction of leaf extract: without induction, induction of Clerodendrum japonicum and Mirabilis jalapa leaf extract. Data obtained were analyzed with F test, and were continued with DMRT at 5 percent when significant.Results showed that induction of leaf extract depends on eggplant varieties were used. An green eggplant, induction of leaf extract not affected on the percentage of the level and intensity of eggplant yellow leaf virus disease, while an purple eggplant, induction of leaf extract can decreased the percentage of the level and intensity of eggplant yellow leaf virus disease. The yield of an green eggplant not increased on induction of leaf extract, while the yield incresed an purple eggplant on induction of leaf extract.

Application of Raw Secondary Metabolites From Four Entomopathogenic Fungi Against Chilli Disease Caused by Viruses

“…Chloroplast is the main organelle that is attacked by plant viruses. The decreased rate of photosynthesis is caused by an abnormal form of chloroplasts, with a relatively smaller size and the amount of thylakoids in each grana which are decreased due to viral infection (Ali & Aprilia, 2018).…”
