biological control of soil borne plant pathogens with antagonistic microorganism has been more attracting interest. especially, burkholderia strains have been intensively investigated as biological agents. the objective of this study was finding an effective biologica control agent against the canola damping off caused by rhizoctonia solani. rhizoctonia damping-off is one of the most important ...

Background: The aim of this study was to investigate the thyroid function status in patients with lichen lanopilaris.Methods: In this case control study, 26 (8 male and 18 female) consecutive lichen planopilaris patients, and 36 age and sex matched controls were evaluated for thyroid function status.Results: The median antithyroglobulin serum level was higher in patients than controls (47.1 IU/...

The interest in the use of antimicrobial peptides to control fungal diseases in banana plants has been rising in the last years. In this paper we analyzed the antifungal activity of different peptides on the in vitro development of Mycosphaerella fijiensis and found that they inhibited fungal mycelial growth and ascospore germination. All peptides evaluated displayed activity against the fungus...

Fusarium wilt diseases caused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Biocontrol agents such asTrichoderma viride , Trichoderma harzianum and Pseudomonas fluorescens are applied to control Fusarium wilt of Arachis hypogaea. Experiments were conducted on the effect of culture filtrates of T.viride (1%), T.harzianum (1.5%), and P. fluorescens (2%) on biochemica...

The genus Trichoderma comprises a great number of fungal strains that act as biological control agents, the antagonistic properties of which are based on the activation of multiple mechanisms. Trichoderma strains exert biocontrol against fungal phytopathogens either indirectly, by competing for nutrients and space, modifying the environmental conditions, or promoting plant growth and plant defe...

First of all, since the area of biological control is so vast, I will be restricting my talk to the area of biocontrol of postharvest fruit pathogens. Fungicides are a primary means of controlling postharvest diseases. However, as a result of public concern about the presence of synthetic chemicals in our food supply and environment, several fungicides have been banned by the U. S. Environmenta...

Chemical insecticides have been commonly used to control agricultural pests, termites, and biological vectors such as mosquitoes and ticks. However, the harmful impacts of toxic chemical insecticides on the environment, the development of resistance in pests and vectors towards chemical insecticides, and public concern have driven extensive research for alternatives, especially biological contr...

salinity stress is one of the most important abiotic factors that restrict the growth and yield of many plants. salinity can increasingly influence the host susceptibility, occurrence and development of plant diseases due to its negative effects on the host plants. mycorrhizal fungi are able to increase the tolerance of some plants to salinity. in this study, the biological effects of glomus mo...
