  • 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 ...

  • Recognition of the Magnaporthe oryzae effector AVR-Pia by the decoy domain of the rice NLR immune receptor RGA5

    Abstract Nucleotide-binding domain and leucine-rich repeat proteins (NLRs) are important receptors in plant immunity that allow recognition of pathogen effectors. The rice NLR RGA5 recognizes the Magnaporthe oryzae effector AVR-Pia through direct interaction. Here, we gained detailed insights into the molecular and structural bases of AVR-Pia-RGA5 interaction and the role of the RATX1 decoy ...

  • Potassium and winter hardiness

    The role of Potassium in metabolic processes such as protein synthesis and the movement of sugars within the plant is now well understood and recognised as crucial for maximising quality and yield. But it is now known Potassium also plays a significant role in helping crops resist disease and environmental stresses during winter dormancy and ensuring optimum supplies of Potassium to see crops ...

  • Non-chemical Pre-plant Soil Disinfestation

    The battle with pests, diseases and weeds is an everyday problem for every farmer. Due to the fact that 40% of the world’s food production is lost due to pests and diseases, farmers need to manage crop protection. An excellent example of the need for pesticides is cotton. It is a crop that is affected by various pests. Cotton farming accounts for more than 25% of all insecticides and 12% of ...

  • What is it about this soil that protects plants from devastating disease?

    Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. ...

  • A Functional Link Between Mitochondria and the Cell Wall in Stress Responses

    Both mitochondria and the cell wall are targeted by and respond to stresses. The cell wall is physically affected by abiotic stresses and is the site of initial attack by pathogens. During stress responses, the cell wall is remodeled to maintain integrity and allow flexibility (reviewed in Hamann, 2015; Tenhaken, 2015). Similarly, stresses can alter mitochondrial function, especially in terms of ...

  • 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 controlled ...

  • Playing hide and seek below the soil

    Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...

  • Control of Microthrix parvicella by aluminium salts addition

    Aluminium and iron chloride were added to a biological nutrient removal pilot plant (1,500 population equivalent) treating urban wastewater to investigate the control of Microthrix parvicella bulking and foaming by metallic salts. Monitoring plant performance over two 6-month periods showed a slight impact on the removal efficiencies. Addition of metallic salts (Me; aluminium or aluminium + ...

  • Presence and persistence of wastewater pathogen Escherichia coli O157:H7 in hydroponic reactors of treatment wetland species

    Treatment wetlands (TWs) efficiently remove many pollutants including a several log order reduction of pathogens from influent to effluent; however, there is evidence to suggest that pathogen cells are sequestered in a subsurface wetland and may remain viable months after inoculation. Escherichia coli is a common pathogen in domestic and agricultural wastewater and the O157:H7 strain causes ...

  • Food security faces growing pest advance

    Coming soon to a farm near you: just about every possible type of pest that could take advantage of the ripening harvest in the nearby fields. By 2050, according to new research in the journal Global Ecology and Biogeography, those opportunistic viruses, bacteria, fungi, blights, ...

  • Effect of nano-silver particles on postharvest life of Lilium orientalis cv. ‘Shocking’

    Prolongation of vase life of cut lilies ( Lilium orientalis cv. ‘Shocking’) was studied in vase containing 5, 15, 25, 35 ppm of nano-silver solutions and deionised water as control under controlled conditions. All nano-silver treatments extended the longevity of cut flowers in comparison to control but the concentration of 35 ppm showed the highest vase solution uptake, initial fresh weight ...

  • New approaches are needed for another Green Revolution

    Twenty-first century agriculture needs low-input advances like the System of Rice Intensification, says Norman Uphoff. According to the principle of diminishing returns, continuing to produce something in the same way, with the same inputs and technology, ...

  • Translocation for conservation: helping or harming wild populations?

    The value of moving animals or plants from a stable population into one that is endangered or even extinct has been questioned, with some suggesting that it will mean that the new population is not well adapted to its environment. However, research on an endangered toad has shown that even when individuals were translocated from great distances, the population was able to genetically adapt to ...

  • Review: Effects of olive mill wastewater application on soil properties and plants growth

    Comparative effects of untreated olive mill wastewater (UOMW), treated olive mill wastewater (TOMW) and bioaugmented olive mill wastewater (BOMW) on soil properties, on seeds germination and on plants growth were investigated. The water holding capacity, the salinity, the organic carbon content, humus, total nitrogen, phosphate and potassium increased when the spread amounts of UOMW (50, 100 and ...

  • Innovation of the Month: Food Fermentation for Biopreservation

    Although the word “bacteria” is usually associated with sickness and disease, it is the driving force behind fermentation, a food process on which humans have relied for millennia. Some of the earliest recorded instances of fermentation come from East Asia where, according to William Shurtleff, founder of the ...

  • The possibility of determining of anomalies and pathologies in the offspring of liquidators of Chernobyl accident by non–radiation factors

    Hereditary effects of radiation on people are not revealed and estimations for humans have been carried out by extrapolation from mutagenesis of irradiated mice (UNSCEAR). Nevertheless, in Russia, Ukraine and Belarus disturbance and pathologies are found in the children of liquidators of the accident at the Chernobyl atomic power station. Authors connect effects only with irradiation (basically ...

  • Field trial carried out in the ebro valley, Spain case study

    Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

  • Response of bt and near-isoline corn hybrids to plant density

    Transgenic Bt (Bacillus thuringiensis) corn (Zea mays L.) hybrids with resistance to corn rootworm (CRW; Diabrotica spp.) or European corn borer [ECB; Ostrinia nubilalis (Hübner)] can have greater tolerance to water and nutrient stress, and thus may have higher optimum plant densities. Experiments were conducted following soybean [Glycine max (L.) Merr.] over nine site-years in Illinois to ...
