Abstract
F. oxysporum is the causal agent of Fusarium wilt. This disease is known to penetrate the roots of plants and wilt the vascular system. The most common method for control is through the use of synthetic fungicides, which are known to cause adverse effects on the environment and human health. Thus, it is necessary that more methods of biocontrol be explored. Current literature shows that various salts and essential oils are effective for the biocontrol of F. oxysporum. However, the two types of substances have not yet been tested together, causing a gap in current research. Due to the antifungal properties of both substances, it can be hypothesized that a combined treatment of the two would result in a synergistic effect on the F. oxysporum. 50 samples were poured into Petri dishes with the treatment mixed into the agar and inoculated with agar discs containing F. oxysporum. Percent inhibition was calculated after incubation at 25±1℃ using the following equation: I = (dc-dt)/dc x 100. The results showed that the combination of sodium bicarbonate and neem oil had 73.3% as the highest inhibition rate. The positive control (acetone) had the second-highest inhibition rate of 51.1%. A one-way ANOVA test (F(4,45)=95.977, p=1.1102e-16) showed that there was a statistically significant difference between at least two groups. The post-hoc Tukey test revealed significant differences between many groups, making the results unclear due to errors in the experiment.
