To determine effective methods to help the management and eradication of bacterial wilt at Heliconias National Park, located in Caicedonia municipality, heliconia`s samples with symptoms of bacterial wilt were collected. Ralstonia solanacearum Race 2 was identified as the cause of the disease. The experimental design for assessing bacterial growth was conducted with a factor and four treatments. For treatments was used Grapefruit extract, Bacillus subtilis, copper hydroxide and aqueous extract Swinglea (Swinglea glutinosa). The most effective control of bacteria in vitro was presented in the following order: copper hydroxide (100%), subtilin (92%) and grapefruit extract (36%). The Extract Swinglea glutinosa did not show any inhibitory effect.

Palabras clave : Bio-control; Ralstonia solanacearum Race 2.
