Crop rotation and soil health
They go together like salt and pepper – they’re better together When you have a strong and varied crop rotation, it produces a greater diversity in the soil microbiome, which improves activity both above and below the surface. One of the most critical parts about a healthy crop rotation is bacteria – both good and bad – because when you change crops, you change pathogens. ...

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 ...

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 ...

Can LEDs Affect the Taste and Smell of Vegetables?
There is a widespread misconception that the taste of vegetables is solely based on genetics of the plant species and cannot be enhanced by cultivation techniques or environmental conditions. That would be true in a scenario where other cultivation parameters were universally normalised. However, this is rarely the case when it comes to indoor vegetable production facilities. The cultivation ...

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 ...

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 ...

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 ...

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 ...

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 ...

Study: Biological treatments in early production of tomatoes
At Vineland Research and Innovation Centre in Ontario, Plant Pathology Research Technician Travis Cranmer is working to analyze the efficacy of biopesticides against root diseases in hydroponic tomato production. The study’s findings were released at the Canadian Greenhouse Conference in Niagara Falls in October 2016. Cranmer shares some of his ...

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 ...

Biopesticides Examined for Role in Field Production
Biopesticides deserve respect. Once derided as snake oil, today’s products have proven benefits in suppressing pest organisms. Whether they activate plant defenses, parasitize or inhibit pathogen growth or make the environment less favourable to disease, they can play an integral role in crop protection. While the greenhouse sector first excelled at incorporating biopesticides in ...

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, ...

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 ...

Implementing case studies in a plant pathology Course: Impact on student
Case studies have been used in undergraduate science education as a way to develop students' critical thinking and problem-solving skills. However, little empirical evidence exists on whether this teaching method is having the desired impact on students in plant pathology courses. This study evaluated the influence of the case teaching method on students' problem-solving and critical thinking ...

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 ...

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. ...
