In vitro studies with Trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. Microscopic observations showed that T. harzianm and T. viride, isolated from soil samples from Ahwaz and Karaj, adversely affected the myce...

Background: Pulicaria gnaphalodes, Ducrosia anethifolia, Trachyspermum copticum, Foeniculum vulgare Mill and Majorana hortensis Minch are widely used as herbal plants in traditional medicine and they have been reported to have a variety of therapeutic effects. This study was carried out to evaluate the antimicrobial effects of essential oils (EOs) extracted from these medicinal herbs against si...

Pathogens transmitted by arthropod vectors are common in human populations, agricultural systems and natural communities. Transmission of these vector-borne pathogens depends on the population dynamics of the vector species as well as its interactions with other species within the community. In particular, predation may be sufficient to control pathogen prevalence indirectly via the vector. To ...

Among the millions of microorganisms inhabiting soils, some can be plant pathogens, meaning they become a disease to plants. Some diseases are more well-known than others. This is case clubroot, very atypical microorganism that infects cruciferous plants, such as cabbage, kale, canola, and common research thale cress. In this article, I will tell you about clubroot because there still lot disco...
