The Increase in Effectiveness of Broccoli Waste as Bio-Fumigant to Control Ralstonia Solanacearum on Tomato (Solanum lycopersicum L.)

Abstract

The use of synthetic bactericide can cause the death of natural enemies and pathogenic resistance. Innovation is needed to replace methyl bromide solution. Research to find biofumigan compounds as an alternative to methyl bromide is considered essential. Waste broccoli biofumigan known as a source because it contains glucosinolates (GSL). If out of the plant tissue, the GSL will be hydrolyzed to compounds that are toxic to pests and pathogens. The research aimed to obtain optimum dose for broccoli waste to control the attack of Ralstonia solanacearum disease and increase tomato yield. Research was conducted at Screen House of Faculty of Agriculture of Islamic University of Malang on February - June 2014. The research was conducted experimentally using completely randomized block design with three replications. Research result indicated that the application of broccoli waste of 400 g per 5 kg of soil has able to extend the incubation period to 11 days, decrease disease incidence of 86.18%, decrease the population of Ralstonia solanacearum 75.45%, and increase plant yield of 129.29% and number of plant fruit of 13.87%.
