Abstract

Shallots (Allium ascalonicum L.) are agricultural commodities that are goodly demanded by the
community. Fusarium wilt caused by the fungus Fusarium oxysporum is a dominant problem in the
cultivation of this plant. The way to control this disease is to use liquid smoke from empty oil palm fruit
bunches. Conduct research in February-September 2021 at the Laboratory of the Plant Protection Study
Program and Experimental Land, Faculty of Agriculture, University of Lambung Mangkurat Banjarbaru.
Two-stage experiments (in vitro and in vivo) were carried out in this study, using a completely randomized
design with five treatments (without treatment and liquid smoke with concentrations of 1, 2, 3%, and 4%).
Fusarium oxysporum was injected in all treatments. The results of in vitro studies showed that giving as
soon as possible with a concentration of 3% allows for inhibiting the growth of the fungus Fusarium
oxysporum. in vivo showed that the application of 2 times a week is better than all treatments
