  • Tests of taxonomic and biogeographic predictivity: Resistance to disease and insect pests in wild relatives of cultivated potato

    A major justification for taxonomic and biogeographic research is its assumed ability to predict the presence of traits in a group for which the trait has been observed in only a representative subset of the group. Such predictors are regularly used by breeders interested in choosing potential sources of disease and pest resistant germplasm for cultivar improvement, by genebank managers to ...

  • Introgession of wild species germplasm with extreme resistance to cold sweetening into the cultivated potato

    Potato (Solanum tuberosum L.) breeders are interested in developing chipping cultivars that can be stored at cold temperatures to reduce storage losses and increase profitability for potato producers. Commercial cultivars accumulate reducing sugars during cold storage, resulting in unacceptably dark chips when processed. In this study, we have identified diploid wild Solanum species accessions ...

  • 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 ...


  • Advancements in chemistry are providing growers with flexibility when managing slug pressures in potato crops.

    Flexibility in slug control The mild and wet weather and lack of ground frosts seen this winter, means that being vigilant to slug activity will be key as we move into the potato planting season. Andrew Sprunt, Agrii’s Northern region potato technical agronomist, explains what growers can expect from the season ahead, and how to manage the potential impact at farm level, ...

  • Bulk carbon, oxygen, and hydrogen stable isotope composition of recent resins from amber-producing Hymenaea

    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 ...

  • Compost, manure and synthetic fertilizer influences crop yields, soil properties, nitrate leaching and crop nutrient content

    From 1993 to 2001, a maize-vegetable-wheat rotation was compared using either 1) composts, 2) manure, or 3) synthetic fertilizer for nitrogen nutrient input. From 1993 to1998, red clover (Trifolium pratense L.) and crimson clover (Trifolium incarnatum L.) were used as an annual winter legume cover crop prior to maize production. From 1999 to 2001, hairy vetch (Vicia villosa Roth.) served as the ...

  • Lindsay Irrigation advances Watertronics AG Pump Stations case Study

    When AJ Ochoa, a fourth generation Othello, Wash. farmer pushed one button to start his new Watertronics® agricultural pump station, he became one of the first irrigators in the world to reap the benefits of a fully integrated pump and center pivot water control package. Even more important to Ochoa, he began realizing immediate and substantial reductions in energy, water and labor costs. ...

  • How three U.S. mini-farms are sowing the seeds of global food security

    Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

  • A big slug year ahead?

    In addition to the weather, stubble clean-ups and green bridge carry-over are the two other major contributors, which means that high slug pellet usage on farms across the UK is likely this year, explains Justin Smith agronomist for Bartholomews Agri Food Ltd. “I work with farmers in the East Sussex and Kent areas, most of whom farm in vulnerable water catchment areas and are looking for ...

  • Regional roundup

    Ithaca, New YorkCOMPOSTING PET WASTE AT DOG PARKCayuga Compost and Tompkins County Dog Owners Group launched a program on Earth Day this year to collect and compost pet waste at the Ithaca Dog Park. About 5,000 bags are used to collect 1,000 pounds of dog waste every month at the park. Plastic bags were previously provided by Wegmans supermarket, and disposed of in dumpsters going to ...

  • One Year Later · Persistent Herbicides in Compost

    ONE YEAR has passed since the Washington State University (WSU) composting facility and the Spokane Regional Compost Facility discovered traces of persistent herbicides in their composts. In Spokane, the source of contamination is a compound called clopyralid. Compost contamination at WSU initially involved the herbicide picloram, but clopyralid has since been detected in the compost also. In ...


  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • CRISPR is coming to agriculture — with big implications for food, farmers, consumers and nature

    Gene editing offers dramatic advances in speed, scope and scale of genetic improvement. It also offers an opportunity for more nuanced GMO governance. Very few technologies truly merit the epithet “game changer” — but a new genetic engineering tool known as CRISPR-Cas9 is one of them. Since we first developed the ability to alter the genetic material inside a plant or animal in ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
