Abstract: Aims:Wax apple is an important fruit crop in Malaysia and other tropical countries. However, the black spot disease caused by Lasiodoplodia theobromae can damage the wax apple plants, reducing fruit production and quality. Chemical fungicides are commonly used to overcome this disease. However, their overuse might increase fungal resistance to chemicals. Therefore, this study was aimed to evaluate the in vitro antifungal properties of an Aloe vera film incorporated with cinnamon oil on L. theobromae in wax apples.
Methodology and results:In vitro antifungal tests were conducted using the poisoned food. This present study found that the inhibition of L. theobromae mycelia when treated with A. vera film with different percentages of cinnamon oil was significantly different compared to the control film at (P<0.05). Results suggest that A. vera film without cinnamon oil showed the highest percentage of inhibition (37.31%) than other films with cinnamon oil due to the antagonistic and less synergistic effect. However, A. vera film with 0.07% of cinnamon oil showed the highest percentage of mycelia inhibition (36.15%) compared to the film with 0.06%, 0.05% and 0.04% cinnamon oil, with mycelia inhibition of 30.55%, 24.25% and 18.82%, respectively, while the mancozeb (positive control) showed 100% inhibition.
Conclusion, significance and impact of study:In conclusion, A. vera film alone had 37.31% inhibition compared to 36.15% inhibition in A. vera film with 0.7% cinnamon oil. As a result, a tiny amount of cinnamon oil added to the mixture might aid in controlling the black spot disease in wax fruits.
