      Agrobacterium vitis strains are causative agents of crown gall, an economically important disease [1, 2]. A. vitis F2/5 is an effective biological control agent against many A. vitis tumorigenic strains [].Strain F2/5 produces an antibiotic toxic to many A. vitis strains in vitro. However, two lines of evidence suggest that this antibiotic plays a minor role in disease Cited by: BIOCOMES biological control agent. Biological control agents based on microbial antagonists will be tested. Bacterial or fungal antagonists can provide several beneficial effects against damping-off diseases. The microbials can have direct effects on the pathogenic complex reducing their growth and preventing establishment in the rhizosphere.

Fungal plant pathogens are among the most important factors that cause serious losses to. Biological control using fungal and bacterial antagonists to manage plant diseases seems to be a promising alternative strategy and have successfully been applied to control some diseases on different plants and crops.

Biocontrol strategies may also be used to manage other plant diseases including foliar ones.

These antagonists have various modes of action that include antibiosis and/or competition for nutrients and by: Introduction The biological control of plant pathogens was detailed by Van Driesche & Bellows ().

It involves the ecological management of a community of organisms. In the case of plant pathogens, however, there are two distinctions from biological control of organisms such as insects and plants.

The most commercially successful bacterial-based biocontrol system is the use of the nonpathogenic Agrobacterium strains to control crown gall.

The primary modes of action for pathogen control or for management of both bacteria and fungi are competition for C, N, and Fe, or increased colonization of the rhizosphere by the nonpathogenic strains.
