  • Ethylene removal reduces putrefaction in mandarin oranges

    Ehylene removal with Bi-On ( potasium permanganate) reduces putrefaction in mandarin. Citrus fruits are susceptible to various diseases related to air quality that reduce their postharvest life. As they are not climacteric fruits, exposure to ethylene does not stimulate ripening, but instead speeds up the senescence of the fruit. Senescence causes a series of changes and deterioration ...

  • Antimicrobial Action of BiOn

    Bi-On is an air filtration media used in fruit and vegetable sold storage to eliminate harmful volatile compounds, especially ethylene, and sanitize the air. The filtration media is composed of potassium permanganate, its active ingredient, and natural clays. Potassium permanganate is a chemical compound which is widely known for its oxidizing and disinfectant properties. It is used in the ...

  • CPB Filter against fungi infections in Pineapples

    Pineapples are susceptible to different diseases linked to air quality. The main problems include the growth of fungi on the crown, changes in the exterior colour from green to brown and sometimes considerable translucence inside the pineapple. As the pineapple is a non-climacteric fruit, ethylene does not accelerate its ripening, but it does speed up its senescence. Senescence causes a ...

  • USDA Announces $3.8 Million Awarded in Grants for Nano Research

    The U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA) announced on April 27, 2015, that it awarded more than $3.8 million in grants “focused on using nanotechnology to find solutions to societal challenges such as food security, nutrition, food safety, and environmental protection.”  The grants were made through NIFA’s Agriculture and ...

  • Cheap chemicals entice caterpillar-eating wasps to crops

    It may be a win-win situation: treating seeds with commercially available growth promoters before planting could have the added benefit of attracting parasitic wasps that feed on caterpillar pests, suggests a study. The protective effect of these cheap, commercially available chemicals, known as ‘plant strengtheners’, can help protect young ...

  • The survival of mycobacteria in pure human urine

    Mycobacterial pathogens can be excreted in human urine by some infected individuals. High numbers of pathogenic mycobacteria in the urine could represent a new transmission route for mycobacterial infections if the urine is used for crop fertilization. In this study, the survival of spiked Mycobacterium aurum and M. fortuitum as fast-growing mycobacteria and M. ...

  • 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 ...

  • Effect of transparent covers for collection chambers of urine-diverting dry toilets on dehydration of faecal waste

    Urine-diverting dry toilets save water, reduce the demand for wastewater treatment and provide plant nutrients. The conditions in the collection chambers and the interlinked hygienic safety of subsequent faecal matter use in crop production are affected by the building design. Comparative experiments were carried out to evaluate the potential of transparent chamber covers in comparison with ...

  • Compost curing reduces suppression of plant diseases

    Prolonged curing of compost reduces risks of phytotoxicity but may also have an undesirable effect on suppressiveness against soil-borne diseases. In a previous study, this effect was demonstrated for a compost produced from a mixture of yard waste and biosolids, against Sclerotium rolfsii. The aim of the present study was to demonstrate that similar effects of prolonged curing may be exhibited ...

  • 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 ...

  • Recently planted vegetation strips reduce Giardia runoff reaching waterways

    Current methods for tracking pathogens across farmland and into surrounding waterways via runoff are limited and typically have been developed using artificially created landscapes. No studies have investigated how Giardia in farm runoff moves across the landscape, despite high prevalence rates in dairy cattle (Bos taurus) worldwide. Here, we report the development of a field-based tracking ...

  • The asexual pathogen aspergillus fumigatus expresses functional determinants of aspergillus nidulans sexual development

    The major fungal pathogen of humans, Aspergillus fumigatus, lacks a defined sexual cycle, although the presence of genes encoding putative mating type idiomorphs and regulators of Aspergillus sexual development heightens the potential for cryptic sexuality in this deuteromycete. To test the functionality of these genetic determinants, we transferred the alpha box-encoding mat1-1 idiomorph from ...

  • Corn grain yield response to crop rotation and nitrogen over 35 years

    Crop rotation and N are management methods that can increase corn (Zea mays L.) grain yields. Our objective was to determine the corn grain yield response to six crop rotation sequences and four N rates in a long-term (35-yr) study. The rotations were continuous corn (CC), corn–alfalfa (Medicago sativa L.) (CA), corn–soybean [Glycine max (L.) Merr.] (CS), corn-corn-corn-alfalfa-alfalfa (CCCAA), ...

  • Grain legumes in northern great plains

    Cropping systems in the Northern Great Plains have shifted from fallow-based to legume-based systems. The introduction of grain legumes has impacted soil organisms, including both symbiotic and nonsymbiotic N-fixing bacteria, pathogens, mycorrhizae and fauna, and the processes they perform. These changes occur through effects of legume seed exudates, rhizosphere exudates, and decomposing crop ...

  • Advances in control of postharvest diseases in tropical fresh produce

    With increased global trade, fresh produce is increasingly being moved over vast distances to foreign markets. This requires effective cold chain and product management practices to ensure premium quality fresh produce with increased shelf life. Product safety has now also become an additional minimum requirement for market entry. Producers should therefore take cognisance of the impact ...

  • Method, creativity and CIALs

    CIALs (Committees For Local Agricultural Research) are community level organisations for helping agricultural scientists and farmers to collaborate on adaptive research. Although CIALs have been used mainly for testing new crops and varieties, an unorthodox project in Peru and Bolivia recently used CIALs with a range of research techniques: formal trials, participatory research and farmers' own ...

  • 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 ...
