Four bacteria isolates from the rhizosphere of Drosera villosa var. villosa (B1, B2, B3, B4) and two Bacillus thuringiensis isolates (B5 e B6), being B6 a bioinsecticidal Cry1Ab protein producer, were tested for their capacity to inhibit phytopathogenic fungi such as Fusarium solani f. sp. phaseoli, Fusarium solani f. sp. glycines, Fusarium oxysporum and Colletotrichum sp. The B1 isolate was highly effective and inhibited all fungi up to the 26th day. B. thuringiensis inhibited the growth of three fungi, and this result opens a new area to study and test B. thuringiensis.
