Sclerotinia sclerotiorum, which causes white mold, is a widespread pathogen. In 2020, new host plant of this fungus, the watercress (Nasturtium officinale) was identified in Hungary an aquaponic system. During cultivation S. sclerotiorum detected on plant, fungus caused 30% yield loss. Fungicides should not be used against fungi systems. Non-chemical methods integrated pest management used. The...

Elicitors of biological origin, especially those that are able to control plant pathogens by induction of plant systemic resistance are being intensively investigated because of their great potential for crop protection and environmental compatibility. Since the range of induced defense responses can depend on the elicitor used, the plant treated and the target pathogen, a detailed study of the...

chromatomyia horticola (goureau) (diptera: agromyzidae) is a highly polyphagous leaf miner that causes severe damage to different crops. sampling on the alysiinae (braconidae) parasitoids of c. horticola was performed at various locations of kermanshah province during 2009–2010. infested leaves of host plants bearing the larvae and puparia of c. horticola were collected and placed inside the pl...

The recent invasion by Ambrosia artemisiifolia (common ragweed) has, like no other plant, raised the awareness of invasive plants in Europe. The main concerns regarding this plant are that it produces a large amount of highly allergenic pollen that causes high rates of sensitisation among humans, but also A. artemisiifolia is increasingly becoming a major weed in agriculture. Recently, chemical...

Bacillus subtilis and other Bacilli have long been used as biological control agents against plant bacterial diseases but the mechanisms by which the bacteria confer protection are not well understood. Our goal in this study was to isolate strains of B. subtilis that exhibit high levels of biocontrol efficacy from natural environments and to investigate the mechanisms by which these strains con...

Bacteria and fungi that colonise plant surfaces and internal plant tissues (epiphytes and endophytes respectively) are ubiquitous, residing latently or actively colonising the plant locally as well as systemically. Endophytic microorganisms generally originate from the epiphytic communities of the root or aerial surfaces as well as from within seed material. Besides entering plants through natu...

The relationships among the chemical, physical and biological aspects of compost and their role in suppression of turfgrass pathogens are reviewed. The composting process, mediated by microbial activity, is a€ected by physical and chemical characteristics which include temperature, aeration, moisture content, C:N ratio and pH. In the absence of parameter restrictions, the microbial community fo...

The aim of this work was to study the fungal diversity in Paspalum notatum, order determine potential biological control disease-causing pathogens and their effects on growth promotion. Two isolates Cercospora dianellicola were identified from asymptomatic P. notatum leaves, as an endophytic species. possible benefits for host plant remain be analyzed.

Protection provided by host bacterial microbiota against microbial pathogens is a well known but ill-understood property referred to as the barrier effect, or colonization resistance. Despite recent genome-wide analyses of host microbiota and increasing therapeutic interest, molecular analysis of colonization resistance is hampered by the complexity of direct in vivo experiments. Here we develo...

anthocoris nemoralis (f.) (hemiptera: anthocoridae) is one of the most prominent predators of the pear psylla, cacopsylla pyricola (forster) (hemiptera: psyllidae) and is considered as a biological control agent against this pest. in order to investigate the effects of plant varieties on predation of c. pyricola by a. nemoralis, the functional response of both the sexes of a. nemoralis to pear ...
