Background:Ralstonia spp. is a major pathogenic microbe for tomato, which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. Ralstonia spp. produces several virulence factors helping it to invade the plant's natural defense mechanism. Native isolates of Trichoderma spp., Pseudomonas fluorescens and B...

Some Plant Growth-Promoting Rhizobacteria (PGPR) can induce protection against pathogens, increasing plant tolerance to various diseases. This so-called biocontrol activity is replacing harmful practices in agriculture caused by the use of agrochemicals. Azospirillum brasilense one PGPR already effectively used as a resistance inducer several crops. The aim this study was evaluate protective ef...

Beans are one of the most important foods for majority world's population, and Brazil is third largest producer. This production can be affected by pests diseases, such as gray stem rot, caused fungus Macrophomina phaseolina, which difficult to control due low efficiency chemical products. One viable alternatives use microorganisms and/or secondary metabolites pathogen promote plant growth. The...

Fungi in the genus Trichoderma have been used for the production of lytic enzymes and to control a wide range of plant pathogenic fungi. In the last years, much progress has been made in elucidating the molecular biology of Trichoderma spp. The objective of this chapter is to provide a summary of data concerning size and organization of the genome and gene structure in Trichoderma spp., mainly ...

The necrotrophic fungus Macrophomina phaseolina is an important pathogen of many crops, such as strawberry, maize, sorghum, potato, soybean, chickpea, and pigeon pea, causes multiple diseases throughout the world. microsclerotia, which are source primary inoculum, play role in survival spread M. phaseolina, well disease initiation development. South Asia has unique characteristics relative to c...
