Grafting has been increasingly used to overcome soilborne pathogens. The commercial rootstock hybrids AF-8253 (Sakata) and Fortaleza (Takii), as well Embrapa’s new hybrid, BRS Acará, were evaluated rootstocks for the bell pepper Margarita (Syngenta) Pampa (Clause) scions, under natural infestation of Ralstonia pseudosolanacearum, upon artificial inoculation with a) ten isolates, b) one Phytopht...

A variety of non-chemical alternatives to methyl bromide (MB) fumigation of soil for horticultural crop production have been researched in the USA. Non-chemical alternatives are highly desirable but difficult to implement to reproduce the benefits normally obtained by preplant fumigation of soil in strawberry production. Production of pathogen-free, high-quality planting materials using steam a...

Development and application of non-fumigant measures for the control of soilborne diseases in field level production systems is limited by the capacity to consistently predict efficacy. Although organic amendments have repeatedly been evaluated for the potential to provide an environmentally sustainable means to manage soilborne diseases, adoption of such methods has been limited to very specif...

background bacterium-bacterium antagonistic interactions could be important in the ecology of marine bacteria. antimicrobial properties of microorganisms are exploited in various fields of human activities. objectives antagonism of heterotrophic bacteria from different marine environments of tropical and temperate zones was examined. materials and methods bacteria were isolated from biofilm sam...

the production and use of synthetic nanoparticles is growing rapidly, and therefore the presence of these materials in the environment seems inevitable. titanium dioxide (tio2) presents various possible uses in industry, cosmetics, and even in the treatment of contaminated environments. studies about the potential ecotoxicological risks of tio2 nanoparticles (nano-tio2) have been published but...
