Table 6

Efficacy of different concentrations of E. cinerea ethyl acetate fraction (EtOAc-F) in suppression of tomato gall formation induced by A. tumefaciens B6.

Treatment (mg/w)	Number of analyzed plants	Average of gall weight (g)	Reduction of gall weight (%)
Control (untreated)	10	0.4 ± 0.2	0
0.625	10	0.02 ± 0.02	95
2.5	10	0.01 ± 0.01	97.5
4	10	0	100

Data are expressed as mean ± SD for average of gall weights of 30 galls in each group. Significant differences were observed between control and treated groups: ; no significant differences were observed between treated groups: .
