This experiment was performed to investigate the effect of some Trichoderma spp. isolates as growth promoters of cucumber (Cucumis sativus L.) seedlings under greenhouse conditions. Inoculai of 19 Thrichoderma spp. isolates were prepared from disinfected wheat grain. The upper half of the soil in pots (containing field soil and sand) was mixed with these inoculai at 3% ratio and the pots were i...

Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

is the major bacterial disease in tomato, Background: Ralstonia solanacearum which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. R. produces several toxins helping it to invade the plant’s natural solanacearum defense mechanism. Native isolates of Trichoderma spp., Pseudomonas and can be used as...

ABSTRACT Fungi in the genus Trichoderma have been known since at least the 1920s for their ability to act as biocontrol agents against plant pathogens. Until recently, the principal mechanisms for control have been assumed to be those primarily acting upon the pathogens and included mycoparasitism, antibiosis, and competition for resources and space. Recent advances demonstrate that the effects...

Biological control agents for plant diseases are currently being examined as alternatives to synthetic pesticides due to their perceived increased level of safety and minimal environmental impacts. Fungal biological control agents have several mechanisms of action that allow them to control pathogens, including mycoparasitism, production of antibiotics or enzymes, competition for nutrients and ...

Trichoderma spp. Is one of the widespread saprophytic fungi in rhizosphere, which have received considerable attention as potential bio-control agents against most of plant pathogens as well as high utility towards medical and industrial sciences. The advent of molecular era could be judiciously utilized for investigations in fungal taxonomy prompted research in the mid-nineties to re-assess th...

fluorescent pseudomonads are important biocontrol agents showing capability to restrict or suppress phytopathogens, especially the fungal pathogens via production of some inhibitory metabolites and siderophores directly, and promote the plant growth through some different phytohormones. the objective of this research is to screen and introduce pseudomonas fluorescens utpf68 as a new biocontrol ...

Understanding soil microbial communities in agroecosystems has the potential to contribute to the improvement of agricultural productivity and sustainability. Effects of conversion from long-term wheat plantation to Jerusalem artichoke (JA) plantation on soil fungal communities were determined by amplicon sequencing of total fungal ITS regions. Quantitative PCR and PCR-denaturing gradient gel e...

Trichoderma asperellum has been fronted as a biocontrol agent of root-knot nematodes on tomato and French beans in Kenya. Research on the effect of T. asperellum on growth of Rhizobium species is lacking yet the two interact within the rhizosphere particularly when T. asperellum is applied as a biocontrol agent. Legume roots and Rhizobium species have symbiotic relationship resulting in biologi...
