The efficacy of disinfectants against plant pathogens
In late 2015, a journal article from the European Journal of Plant Pathology was published on research regarding the efficacy of different disinfectants against plant pathogens in irrigation water. All testing as done by the Department of Primary Industries here in Australia for the horticulture and agriculture industries. The disinfectants tested included chlorine, chlorine dioxide (using our ...

Plant Sciences in Agriculture
Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...

The crucial role of the pls1 tetraspanin during ascospore germination in podospora anserina provides an example of the convergent evolution of morphogenetic processes in fungal plant pathogens and saprobes{triangledown}
Pls1 tetraspanins were shown for some pathogenic fungi to be essential for appressorium-mediated penetration into their host plants. We show here that Podospora anserina, a saprobic fungus lacking appressorium, contains PaPls1, a gene orthologous to known PLS1 genes. Inactivation of PaPls1 demonstrates that this gene is specifically required for the germination of ascospores in P. ...

Mitogen-activated protein kinase pathways and fungal pathogenesis
In eukaryotic cells, a family of serine/threonine protein kinases known as mitogen-activated protein (MAP) kinases (MAPKs) is involved in the transduction of a variety of extracellular signals and the regulation of different developmental processes. The MAPK is activated by dual phosphorylation of the TXY motif by MAPK kinase (MEK or MAPKK), which is activated in turn by MEK kinase (MEKK or ...

Microbial communities of Solanum tuberosum and magainin-producing transgenic lines
Antimicrobial peptide magainin II, isolated from the skin of the African clawed toad, has shown activity in vitro against a range of micro-organisms. Transgenic potato lines expressing a synthetic magainin gene show improved resistance to the bacterial plant pathogen, Erwinia carotovora. Culturable bacterial and fungal communities associated with magainin-producing potato plants were compared ...

The sensitivity ratio: A superior method to compare plant and pathogen screening tests
There are numerous plant disease-screening methods used to identify resistance in various crops. It is common practice to prefer the screening method with the smallest root mean square error (RMSE), least-significant difference (LSD), or coefficient of variation (CV). However, valid comparison based on the RMSE or LSD requires both methods to have the same scale while the CV is only applicable if ...

Hyphal growth: a tale of motors, lipids, and the spitzenkorper
Filamentous fungi are a large and evolutionarily successful group of organisms of enormous ecological importance (27, 114). Fungi also have a considerable impact on our economy because they serve as bio-factories for the industrial production of proteins (90, 130) and because many fungi are human and plant pathogens that pose a threat to public health and agriculture (1, 105, 124). The basic ...

The influence of biowaste and garden waste composts on diseases caused by pythium ultimum and rhizoctonia Solani related to the antagonists trichoderma hamatum and flavobacterium balustinum
Soilborne plant pathogens can cause serious losses on both agricultural and horticultural crops. Examples include damping-off diseases caused by Pythium spp. and Rhizoctonia spp., Pythium and Phytophthora root rots, Rhizoctonia crown rot, Fusarium and Verticillium wilts, nematode and even bacterial diseases. Until the fifties, the principal methods to control soilborne diseases were through the ...

Production status of bio organic fertilizer
The fertilizer produced by bio organic fertilizer equipment can improve soil ecological environment and change soil microbial flora, and play a more important role in reducing crop diseases and insect pests. In the process of microbial growth and reproduction, it can secrete a variety of antibiotics and plant growth and elements. It can not only inhibit the activities of plant pathogenic ...

Molecular genetics of pathogenic oomycetes
Parasitic and pathogenic lifestyles have evolved repeatedly in eukaryotes (93). Several parasitic eukaryotes represent deep phylogenetic lineages, suggesting that they feature unique molecular processes for infecting their hosts. One such group is formed by the oomycetes. Traditionally, due to their filamentous growth habit, oomycetes have been classified in the kingdom Fungi. However, modern ...

How long does it take for organic fertilizer fermentation equipment to process compost
According to different raw materials, organic composting fermentation equipment can be divided into high temperature composting and ordinary composting. High temperature composting takes plant materials with high fiber content as the main raw materials, and generates a lot of heat through composting and fermentation under aerated conditions. The temperature of composting is very high (50-60 ...

CoirGreen™ Growbags combine the benefits of coir and growbags
The global gardening culture is changing. In the days gone by, people had to till the soil, get dirty and possibly sweat after a gardening workout. However, now, gardening has become easier and we have a variety of tools that do the work for us. One such tool is the CoirGreen™ Growbag, a 100% biodegradable product. A combination of the benefits of coir and grow bags Combining the ...

Why buy modern organic fertilizer processing machine
The traditional artificial composting is not suitable for the development of modern agriculture. The simple composting method has a long time to treat livestock manure, a low content of organic fertilizer nutrients and a slow release. After years of development, modern organic fertilizer production machine has become the development trend of organic fertilizer production in the future. The ...

Crop protection 2.0: reducing environmental impact in the EU Is it feasible?
By 2023 all EU member states must be complying with more stringent guidelines related to Integrated Pest Management (IPM). “The essence of the new guideline is reducing the environmental impact of pesticides,” says Piet Boonekamp, manager of the Bio-interactions and Plant Health business unit at Wageningen UR. “In principle this European goal can be achieved, as has been shown ...

The Latest in Whitefly Control
Next month’s Greenhouse Canada Grower Day is welcoming leading researchers and crop specialists to help you tackle one of the industry’s biggest challenges. Whitefly is proving to be one of the most difficult pests to control, mainly due to the lack of effective registered chemicals that can eradicate silverleaf whitefly. It is also due to the unwillingness of biological suppliers to ...

Plants Activate `Wartime` Protein Production to Fight Invasion
Plants are constantly attacked by bacteria, viruses and other pathogens. When a plant senses a microbial invasion, fundamental changes occur in the chemical soup of proteins inside its cells, the workhorses of life. In a new study published in Cell, Duke University researchers have uncovered a key ingredient in plant cells that reprograms their protein-making machinery to fight disease. Crop ...

Increasing Lettuce Coloration with LEDs
Using LED grow lights in plant production is a relatively new branch of science. In vertical farming where artificial light sources are used in closed environment it is important to collect data about the individual plant species to be able to produce the right spectrum and light intensity for vegetative and generative growth. Light spectrums can also be used to manipulate the plants growth cycle ...

Fungal diseases are on the rise. Is environmental change to blame?
Scientists and physicians are looking for clues to a worrying increase in fungal infections and exploring ways to reduce the threat. Fungi are everywhere — from the mushrooms that decompose fallen logs in the forest, to the mold that grows in your bathtub, to the microscopic fungal cells that reside naturally on your skin. Scientists estimate there are 1.5 million species of fungi on the ...

How to grow blueberries: Blueberry growing system in hydroponic greenhouse
In recent years, the demand for berries, and more specifically blueberries, has increased. This has led to an increase in surface area and cultivation techniques. Soil is no longer a problem thanks to the existence of optimal substrates for growing blueberries. Of all the berries, blueberries require the most consideration for greenhouse cultivation. We are going to see some of them, as well as ...
