Estreptomicetos no controle da meloidoginose em mudas de tomateiro

Abstract: Resumo -Este trabalho teve como objetivo avaliar o efeito de seis isolados de estreptomicetos na mortalidade e eclosão de juvenis de segundo estádio (J2) de Meloidogyne incognita e no controle da meloidoginose em mudas de tomateiro. Foi montado um bioensaio em placas tipo Elisa, sendo adicionados em cada célula, 200 µL de metabólitos dos isolados, com 20 µL de uma suspensão com 25 juvenis de segundo estádio (J2) de M. incognita. Os metabólitos produzidos por Streptomyces griseus subsp. griseus causaram 98,2% d… Show more

“…They came from the culture collection of the Phytopathology and Microbiology Laboratory of the Agricultural, Environmental and Biological Sciences Center, at Federal University of Recôncavo of Bahia (UFRB) State of Bahia, Brazil. These streptomycetes were isolated from rhizosphere soil of several crops by Lima (2002), and have been selected for plant growth promotion, control of tomato bacteria wilt (Lima, 2002), plant parasitic nematodes Sousa et al, 2005;Sousa et al, 2006) and phytopathogenic fungi .…”

“…Algumas espécies microbianas, como os estreptomicetos e Bacillus subtilis, foram avaliadas como interferentes no ciclo dos fitonematóides apresentando potencial para utilização no controle dos parasitas no solo (Kavitha et al 2007;Sousa et al, 2006). Ficou demonstrado que isolados de B. subtilis não apenas produzem metabólitos tóxicos que afetam o movimento de nematóides mas também podem inibir a eclosão de juvenis e o processo pelo qual eles penetram nas raízes (Araújo et al, 2002).…”

“…N0035, S. purpurascens and S. griseus subspecies griseus rice inoculum caused significant reduction in the number of root galls and egg masses in tomato plants inoculated with M. incognita. Growth promotion was also observed in tomato plants grown in pots with planting mix inoculated with Streptomyces rice inoculum (Sousa, 2006;Sousa et al, 2006). In addition, these Streptomyces species have been indicated as potential biological agents for controlling yam (Dioscorea cayennensis Lam.)…”

“…griseus, Streptomyces sp. N0035, and S. purpurascens, which had been selected in previous work as potential biocontrol agents (Lima, 2003;Soares et al, 2006;Sousa et al, 2006). The cell suspension of each Streptomyces isolate was prepared by adding 15 mL of sterile distilled water to each Petri dish and the Streptomyces colonies were scraped with a bacterial loop.…”
