The study of efficiency of Cyathus spp. to control plant pathogenic bacteria and fungi the results showed that some Cyathus spp. effectively control plant pathogenic bacteria, such as Pectobacteria sp., Pseudomonas sp., Ralstonia solanacearum and Xanthomonas campestris pv. vesicatoria in vitro. The most effective to control Pectobacteria sp. was C. striatus KKU4 with 0.62 cm clear zone diameters. Therefore C. striatus KKU6 could control Pseudomonas sp. with 1.34 cm clear zone diameters, C. pallidus KKUITN2/KKULN2 could control R. solanacearum with 0.85 cm clear zone diameters and C.striatus KKU 5 was the most effective to control X. campestris pv. vesicatoria with 0.29 cm clear zone diameters. The study of antagonistic activity against plant pathogenic fungi by dual culture technique, the results showed that some species could control Fusarium sp. including C. striatus KKU3 and C. earlei KKULP1 with 47.94% and 56.0% inhibition, respectively when placing zero and four days before Fusarium sp. C. stercoreus KKUITP2/KKULP2 and KKUITP3/KKULP3 could control Pythium aphanidermatum when placing before P. aphanidermatum for four days. None of the isolates could control Rhizoctonia solani and Sclerotium rofsii.
