Effect of different plant essential oils on in vitro conidial germination of Collectotrichum gloeosporioides. (A) Relative conidial germination of C. gloeosporioides treated with different plant essential oils on glass slide. Values presented are means and error bars represent the standard errors of the means of four independent experimental replications. Means followed by the same letter are not significantly different at 5% level by least significant difference test. Different essential oil doses were applied 8μl/disc demonstrated in upper (2 μl/disc), middle (5 μl/disc) and bottom (8 μl/disc) graphs. (B) Conidial germination of C. gloeosporioides treated with 8 μl/disc of cinnamon oil and clove oil. Conidial germination was observed under light microscope. Photos were taken at 9 h after treatment. Scale bar represents 20 μm.
