Evaluation of the efficacy of blue-green algal compounds against the growth of either pathogenic or antagonistic microorganisms as well as their effect on the antagonistic ability of bioagents was studied under in vitro conditions. The present study was undertaken to explore the inhibitory effect of commercial algal compounds, Weed-Max and Oligo-Mix, against some soil-borne pathogens. In growth...

The genus Pseudomonas is one of the best-studied bacterial groups in soil, and includes numerous species of environmental interest. Pseudomonas species play key roles in soil, for instance in biological control of soil-borne plant pathogens and in bioremediation of pollutants. A polymerase chain reaction-denaturing gradient gel electrophoresis system that specifically describes the diversity of...

Recent studies have shown that introduced exotic plant species may be released from their native soilborne pathogens, but that they become exposed to increased soil pathogen activity in the new range when time since introduction increases. Other studies have shown that introduced exotic plant species become less dominant when time since introduction increases, and that plant abundance may be co...

Abstract Soil-borne Oomycetes are important pathogens of nursery plants, agricultural and horticultural crops, woody plants in natural ecosystems. They most damaging when overwatered or growing poorly drained sites. Poor growth could result from root infection, damage resulting the anoxic conditions which develop saturated soil, both. This is essential information for devising appropriate manag...

Introduction Organic seed treatments have been limited in organic production, until recently. Agricoat Natural IITM, is reported to be “an organic liquid biological seed treatment applied as a seed film coating and formulated with beneficial microbes, macro and micro nutrients, amino acids, organic acids, enzymes, proteins, vitamins, and minerals.” Natural IITM also is applied to “promote root ...

Grafting is a method of asexual plant propagation that joins plant parts for them to live together. So they will grow as one plant. Normally the method has been largely applied to propagate trees that will not root well as cuttings or whose own root systems are not strong enough or resistant to several soil-borne pathogens. Now the method is used for other crops, as vegetables, such as solanace...

Biological control represents an important approach of agricultural biotechnology for controlling many fungal plant pathogens. Trichoderma spp. are the most promising and effective bioagents against many plant pathogenic fungi. In present paper, two strains of Trichoderma aspellerum isolated from soil were screened for their efficacy against some common soil borne plant pathogens by dual cultur...

Bacillus amyloliquefaciens subsp. plantarum UCMB5033 is of special interest for its ability to promote host plant growth through production of stimulating compounds and suppression of soil borne pathogens by synthesizing antibacterial and antifungal metabolites or priming plant defense as induced systemic resistance. The genome of B. amyloliquefaciens UCMB5033 comprises a 4,071,167 bp long circ...

Iron is a fundamental element for plants as well microorganisms and several pathogens, including Rhizoctonia solani, one of the main soil-borne pathogens tomato. This study demonstrated ability Aureobasidium pullulans strain L1 to produce siderophores how these molecules were, directly indirectly, connected its antagonistic activity iron bioavailability. By ICP-OES (Inductively Coupled Plasma—O...
