  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Cattail plants’ Biomass as a bulking agent in sewage Sludge composting and the effect of the produced Compost on cattail plants’ Growth

    In every Greek island there is at least one town with more than 20,000 inhabitants. Several smaller towns and villages range from a few hundreds to a few thousands in population. Usually in the larger towns there are sewage treatment facilities providing at least secondary treatment of wastewater. In most cases the effluent produced is drained to the sea and the sludge is dumped in landfills. In ...

  • 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 ...

  • Irrigation by Sewage Effluents in Yemen

    Yemen is the least advanced country among Middle East Countries in the sewage reuse and safety control. The current sewage effluent quality in Yemen is generally poor as none of the existing sewage treatment plants produces effluents comply with the effluent quality regulations. The oxidation and stabilization ponds are considered the most appropriate for the warm climate conditions in the ...

  • Soil microbial, fungal, and nematode responses to soil fumigation and cover crops under potato production

    Abstract  Sodium N-methyldithiocarbamate (metam sodium) and 1,3 dichloropropene are widely used in potato production for the control of soil-borne pathogens, weeds, and plant parasitic nematodes that reduce crop yield and quality. Soil fumigation with metam sodium has been shown in microcosm studies to significantly reduce soil microbial populations and important soil processes such as C ...


  • Ammonia sanitization of blackwater for safe use as fertilizer

    Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris ...

  • 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 ...

  • 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 ...

  • Evaluating Microbiology of Compost

    The fact that not all compost is created equal has both producers and growers looking for ways to successfully evaluate compost quality. Traditional compost analysis has focused on NPK and micronutrient concentrations in an effort to mirror fertilizer analysis. Compost, however, is much more complex than fertilizer and its most significant value to the grower may be far more than its mineral ...

  • Effect of fungicide on soybean growth and yield

    In response to rising input costs and narrowing profit margins, soybean [Glycine max (L.) Merr.] producers are continually looking for ways to increase soybean yield. One approach being promoted is the use of foliar fungicides, for both foliar pathogen control and nonfungicidal plant physiological effects. The objective of this field experiment was to evaluate a strobilurin and a triazole alone ...

  • Arbuscular mycorrhizal colonization response to three seed-applied fungicides

    In soybean [Glycine max (L.) Merr.], arbuscular mycorrhizae (AM) enhance nutrient and water status and may increase root resistance to soilborne pathogens. However, the fungicides that are routinely applied to the seed may reduce AM colonization, reducing these benefits. Thus, the objective of this research was to assess the effect of three commonly used seed-applied fungicides on AM colonization ...

  • Technical note: Quorum sensing

    Quorum sensing, or the control of gene expression in response to cell density, is used by both gram negative and gram positive bacteria to regulate a variety of physiological functions including bioluminescence, swarming, antibiotic biosynthesis, plasmid conjugal transfer and the production of virulence determinants in animal, fish and plant pathogens. In all cases, quorum sensing involves the ...

  • Main Applications of Truck Mounted ULV Fogger

    A fogger is a machine which distributes chemicals such as insecticide or disinfectant into an area by means of a fine spray for killing insects and other arthropods. They are often used by consumers as a low-cost alternative to professional pest control services. The number of fogger needed for pest control depends on the size of the space needed to treat. There are different types of ...

  • Effect of ethylene on fruits and vegetables rotting

    In the latest edition of Bioconservacion's Partner Meeting with all its partners from the post-harvest sector, we had the good fortune to have Professor Emeritus Ron Wills from the University of Newcastle in Australia. Dr Wills, with over 50 years experience researching agronomy, agriculture and post-harvest techniques is undoubtedly a leader in the sector and one of the great experts on ethylene ...

  • 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 ...

  • Identification of QTL conferring resistance to fusarium head blight resistance in the breeding line c93-3230-24

    Control of Fusarium head blight (FHB), incited primarily by Fusarium graminearum Schwabe [telomorph Gibberella zea (Schwein)], has been a challenge for barley (Hordeum vulgare L.) producers in the upper midwestern United States for more than a decade. This disease manifests primarily in the form of food safety issues and quality discounts due to the presence of deoxynivalenol (DON), a mycotoxin ...
