Manejo de Ralstonia Solanacearum raza 2 a través de productos químicos y biológicos Management of Ralstonia Solanacearum race 2 through chemical and biological products

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