Identification and morphological characterization of marine actinomycetes as biocontrol agents of Fusarium solani in tomato

Fusarium spp. damages the roots of crops, its control is with synthetic fungicides, however, marine actinomycetes can be an option to use agrochemicals. The objective this work was identification and morphological characterization as antagonists solani (Mart.) Sacc. isolated from diseased tomato plants mangrove sediment actinomycetes, both identified through taxonomic keys molecular techniques. Eight isolates were obtained, H8 being most virulent it F. solani. Thirty isolated, which only four inhibited phytopathogen, A19 one that fungus by 70% Streptomyces sp. Marine may for disease management in agricultural interest.
