  • Plants for supporting Orius species

    Orius laevigatus and Orius majusculus are predatory bugs, which are applied in several crops in greenhouses. They can eat many pests species, including nymphs and adults of thrips species, aphids, whtiteflies, eggs of moths, young caterpillars and spider mites. In some crops such as sweet pepper Orius  survives easily. Cut roses are apparently less suitable for oviposition. For ...

  • Cereal Crops Feeling the Heat

    LIVERMORE, California (ENS) - Warming temperatures since 1981 have caused annual losses of about US$5 billion for six major cereal crops, new research has found. This is the first study to estimate how much global food production already has been affected by climate change. From 1981 to 2002, fields of wheat, corn and barley throughout the world have produced a combined 40 million ...

  • GM cotton genes found in wild species

    Genetically modified (GM) cotton genes have been found in wild populations for the first time, making it the third plant species — after Brassica and bentgrass  — in which transgenes have established in the wild. The discovery was made in Mexico by six Mexican researchers investigating the flow of genes to wild cotton populations of the species Gossypium hirsutum. They found ...

  • Insect diversity improves crop pollination

    The decline in numbers of wild bees has caused concern regarding falling levels of pollination for important agricultural crops. Researchers have now demonstrated that the diversity of the pollinator community can significantly affect pollination. Insect pollination is a vital ecosystem service; a large proportion of the human diet either directly or indirectly depends on animal-based ...

  • Climate change causing species disappearance in mountain areas

    Higher temperatures are affecting mountain ecosystems and their populations, as melting glaciers increase short term water availability but also raise the likelihood of flooding, species migration and long term water shortage, FAO warned today during the commemoration of the International Day of Mountains. “As glaciers disappear and snowlines move upwards, river flows are likely to change and ...

  • Traditional farming `can save threatened species`

    Traditional farming methods are crucial for protecting a number of threatened bird species in the developing world, including bustards, cranes, ibises and vultures, a study has found. Livestock grazing and ...

  • Wild Tomato Species Focus of Antioxidant Study

    Tomatoes are known to be rich in antioxidants such as vitamin C, lycopene, β-carotene, and phenolics. Antioxidants, substances capable of delaying or inhibiting oxidation processes caused by free radicals, are of interest to consumers for their health-related contributions, and to plant breeders for their ability to provide plants with natural resistance to biotic and abiotic stresses. While ...

  • Basic food crops dangerously vulnerable

    In the case of wheat, for instance, as a deadly new strain of Black Stem Rust devastates harvests across Africa and Arabia, and threatens the staple food supply of a billion people from Egypt to Pakistan, the areas where potentially crop and life-saving remnant wild wheat relatives grow are only minimally protected. “Our basic food plants have always been vulnerable to attack from new strains of ...

  • Marrone Bio Innovations Files Patent for a Unique Bacillus Species

    Marrone Bio Innovations, Inc. (MBI) a leading global provider of natural pest management products for the agricultural and water treatment markets, announces the submission of a patent application encompassing a new Bacillus sp. strain F727, to the United States Patent and Trademark Office. This strain was first discovered from soil collected in California by ...

  • Questions and answers on the new proposal for a regulation on preventing and managing invasive alien species

    What are invasive alien species (IAS)? Alien species are plants, animals, fungi and micro-organisms that have been transported across ecological barriers such as mountain ranges, or oceans as a result of human intervention, and have become established in an area outside their natural range. About a quarter of these species are brought into Europe intentionally, for their beauty, ...

  • History sheds revealing light on crop sequencing

    Forty years of crop sequencing trials have recently been collated by the Department of Agriculture and Food WA (DAFWA), giving Western Australian grain growers real insights into the rotational benefits of break crops. Representing more than 160 crop sequence experiments, the results were presented by DAFWA’s Mark Seymour at the Grains Research and Development Corporation (GRDC) supported 2009 ...

  • Coffee pest spreading to other crops in East Africa

    East Africa's horticulture could face a severe crisis due to 'species jump' — whereby a disease moves from a known host to new and unusual ones — affecting fruits, vegetables, and medicinal and ornamental plants. Researchers in Uganda have discovered that the Black Coffee Twig Borer, a devastating coffee pest, has crossed over from Robusta coffee to about 40 plant  ...

  • Time is ticking for some crop`s wild relatives

    New edge of extinction research is creating a revival of conservation and interest in what these old plants mean to the future Experts and photos available on this topic! A botanist brings a species of alfalfa from Siberia, to the United States. His hope? The plant survives, and leads to a new winter-hardy alfalfa.  But what also happened during this time in ...

  • Plant bank to preserve biodiversity of Pacific crops

    The giant swamp taro, the orange-fleshed Fe'i banana and a coconut that grows to half a metre in length are among the native crop species to be saved in a major project that has begun across small islands in the Pacific. The Centre for Pacific Crops and Trees (CePaCT) is coordinating the project in which 1,000 unique varieties of staple fruit and vegetables from 7,500 Pacific islands are being ...

  • Keeping tabs on the next generation of transgenic crops

    A team of government and university crop scientists from across Canada has developed a scientific framework for monitoring the release of second-generation genetically modified crops. The framework is designed to assess the risks of novel genes entering wild populations. First-generation genetically modified (GM)/transgenic crops with novel traits have been grown in a number of countries since ...

  • Sustainable crop protection - what’s around the corner?

    With sustainable usage likely to be a continued focus following the Brexit result, stringent safety criteria is only likely to increase the pressure on pesticide use in the UK, explains David Chandler from the Crop Centre at the University of Warwick. “We’ve experienced ten years of decline in the number of actives available to the industry, and products are not getting easier to ...

  • Environment: Pooling information to combat the threat of alien species in Europe

    How many plants can be found in the Alps that are not native to that region? Which animals were deliberately or accidently introduced to the Danube? How big a threat will they become to local wildlife? EASIN, the European Alien Species Information Network, launched today by the European Commission's in-house science service, the Joint Research Centre (JRC), takes a first step towards answering ...

  • Bee pollination improves crop quality as well as quantity

    Bee pollination improves the shape, weight and shelf-life of strawberries, contributing a staggering €1.05 billion to the European strawberry market per year, new research suggests. By blocking bees from a set of plants, the researchers demonstrated the substantial effects of bee pollination on the quality of the fruit. It is well established that insect pollination increases the quantity of ...

  • Dealing with difficult powdery mildew infections on ornamental crops

    We are now at the peak of the powdery mildew season and, with increasing temperatures and dry weather conditions, susceptible crops are likely to be at high risk of infection. The pathogen There are five different powdery mildew species which attack ornamental crops in the UK. Erysiphe ssp. – this pathogen is mainly ...

  • Wild Bee Decline Threatens U.S. Crop Production

    The first national study to map U.S. wild bees suggests they’re disappearing in many of the country’s most important farmlands — including California’s Central Valley, the Midwest’s corn belt and the Mississippi River valley. If losses of these crucial pollinators continue, the new nationwide assessment indicates that farmers will face increasing costs — and ...
