Resumo -O objetivo deste trabalho foi determinar o tipo e concentração de inóculo mais adequados para induzir a murchade-esclerócio, sem provocar ferimentos em plantas de tomateiro. Os tratamentos foram: 2, 4, 8 e 16 g de arroz colonizado L -1 incorporados ao solo; 2, 4, 6 e 8 escleródios ou discos de micélio depositados na superfície do solo. A utilização de 8 g de arroz colonizado L -1 de solo demonstrou ser a concentração e o tipo de inóculo ideal para experimentos que visem a inoculação do patógeno sem incitação de ferimento. A deposição de discos de micélio e escleródios não ocasionaram incidência da doença.

The performed treatments consisted of 2, 4, 8, and 16 g of colonized rice grains.L -1 soil; 2, 4, 6 and 8 sclerotia or mycelium disks deposited in soil surface. The incorporation of 8 g of colonized rice grains.L -1 soil proved to be the type of inoculum concentration ideal for experiments aimed to induce southern blight with no injury in tomato plants. Deposition of mycelium disks or sclerotia did not result in disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
