  • Glasshouse hygiene - the importance of staying clean

    The nature of ornamental crops will mean plants are often in production for a long time, which can result in pest and disease carry over; so, it’s crucial that growers employ a rigorous hygiene and disinfection routine between crops. Start clean Starting the season with remnants of inoculum in the glasshouse, means growers are already on the backfoot, as the growing ...

The study’s findings were released at the Canadian Greenhouse Conference in Niagara Falls in October 2016. Cranmer shares some of his ...

  • 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 ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • 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 ...

  • How we can save coral reefs (and why we should want to)

    As oceans grow warmer and more acidic, scientists are developing new strategies to rescue the “rainforests of the sea.” Coral reefs are among the most beautiful ecosystems on Earth — “a jeweled belt around the middle of the planet,” in oceanographer Sylvia Earle’s words. They also are extremely valuable. Reefs cover less than one-tenth of 1 percent of ...

  • 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 ...

  • Biocontrol of Escherichia coli O157:H7 exerted by endogenous microflora and oleoresins in minimally processed lettuce and carrot

    The objectives of this study were to analyse the effectiveness of native microflora of lettuce and carrot in controlling Escherichia coli O157:H7 and to evaluate the technological application of oregano and rosemary to control E. coli in vegetables stored at 8?C and 20?C. The interaction between the background microflora of lettuce and carrot with E. coli O157:H7 was observed at 20?C. In samples ...

  • 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 ...

  • 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. anserina. ...
