Abstract

Onion (Allium Ascalonicum L) are one of the leading horticultural commodities that have economic value. In cultivation, Fusarium wilt disease is often damaged caused by the fungus Fusarium oxysporum. This study aimed to examine the effect of biofertilizer application on fusarium wilt disease, growth and yield of onion. The treatments tested were Bion-up biofertilizer, KIBRT, Biostimulant, Azoto-Tricho, anthracol fungicide, and without biological fertilizer as a control. Using a randomized block design with three replications. Observation variables were the incidence of fusarium wilt disease, plant height, number and weight of tubers. The results showed that the application of biofertilizers (Bion up, KIBRT, Biostimulants and Azoto-Tricho) was effective in increasing plant height, number of bulbs, and bulb weight of onion bulbs, while controlling the development of fusarium wilt disease was more effective when using Bion up, KIBRT, and Azoto-Tricho.Keywords: Biofertilizer, Antracol, Shallots, Fusarium oxysporum

Abstract

The cultivation of chili plants is often faced with obstacles such as disease attacks, especially anthracnose disease caused by the fungus Colletotricum capsici and leaf spot disease caused by the fungus Cercospora capsici. This study aimed to determine the effective concentration of T. harzianum secondary metabolites (MSTh) in inhibiting the growth of Colletotricum capsici and Cercospora capsici in vitro. The experiments used various MSTh concentrations: 0%, 10%, 20%, 30%, 40%, and 50%. The research results found that administration of MSTh could inhibit the growth of Colletotricum capsici and Cercospora capsici in vitro. Giving MSTh at a concentration of 10% can significantly inhibit the growth of Colletotricum capsici and Cercospora capsici compared to without MSTh. The effective concentration indicated by the percentage value of inhibitory power and colony weight reduction is an MSTh concentration of 40% with a growth inhibition of Colletotricum capsici of 89.49% and an MSTH concentration of 50% with a growth inhibition of Cercospora capsici of 57.78%.
