Treatments	Well diffusion method
	Zone of inhibition (mm)
	12 h	24 h	36 h
T1 (5 mM)	2 ± 0.01 h	4 ± 0.01e	4.5 ± 0.01d
T2 (10 mM)	2.5 ± 0.01 g	4.75 ± 0.01 cd	5 ± 0.01c
T3 (15 mM)	3 ± 0.01f	5 ± 0.01c	5.5 ± 0.01b
T4 (20 mM)	3.5 ± 0.01f	5.5 ± 0.01b	6 ± 0.01a

Different letters signify significant variations at LSD (P = 0.05), n = 3 and ± indicates standard error between three replicates.
