1. Caracterização de Sarocladium oryzae e seu potencial na redução de brusone foliar em arroz
RESUMO O manejo integrado de brusone (Magnaporthe oryzae) em arroz é realizado, principalmente, com a adoção de controle químico. No entanto, a busca por práticas alternativas tem crescido nos últimos anos. Assim, avaliou-se a variabilidade de 28 isolados de Sarocladium oryzae, quanto à produção de cerulenina, e o seu potencial na redução da sever

2. Potential for using crude extract of Sarocladium oryzae for suppression of rice blast
Crude extract of an isolate of the fungus Sarocladium oryzae (CNPAF So 20G), containing the antimicrobial cerulenin, was produced and its antagonistic potential on the rice blast pathogen Magnaporthe oryzae was asessed. Cerulenin was detected in crude extract of S. oryzae through thin layer chromatography showing a Rf value of 0.63. The quantity of cerulenin

3. Increased enzymatic activity in rice leaf blast suppression by crude extract of Epicoccum sp
Epicoccum sp. showed in vitro antagonism to the rice pathogens Magnaporthe oryzae, Rhizoctonia solani, Sarocladium oryzae, Monographella albescens and Cochliobolus miyabeanus in dual culture. The colony growth of the rice blast fungus, M. oryzae, was reduced by 42.50%. The lethal doses (LD50) determined based on probit-log dosage response curves at 3 and 6 h

5. Evaluation of Pseudomonas fluorescens for Suppression of Sheath Rot Disease and for Enhancement of Grain Yields in Rice (Oryza sativa L.)
Pseudomonas fluorescens strains antagonistic to Sarocladium oryzae, the sheath rot (Sh-R) pathogen of rice (Oryza sativa L.), were evaluated in greenhouse and field tests for suppression of Sh-R severity and enhancement of grain yields of rice. Imprints of rice seedlings and a direct-observation technique of staining roots with fluorochromes confirmed the as
