  • Could traditional plants hold the secret to saving crops from pests?

    Researchers build on age-old practices to reduce food loss in Africa Without any effort at all, Hawa Saidi Ibura crushes dried beans, one at a time, between her fingers outside her home in Endagaw, a village in northern Tanzania. She’s holding a basket of a type of red bean eaten all over East Africa, but these beans ...

  • Bt-cotton and secondary pests

    Bt-cotton seed has been effective to control the damage of bollworm in Chinese cotton production since 1999, reducing the need for pesticides and increasing incomes of Chinese farmers. Field data collected in 2004 indicates that these benefits have been eroded by increasing the use of pesticides aimed to control secondary pests. The combination of Bt-cotton seed and other forms of biological pest ...

  • On-time Pest Protection

    Farming can be a beautiful job under an open sky. But sometimes that ”open sky” determines the flow of farming, total yield, and productivity according to the weather (rain, drought, hail, frost). Since the weather is a major factor in farming, farmers need to manage certain practices to protect their crops from bad weather conditions as well as from various insects and diseases ...

  • Root-knot nematode-resistant alfalfa suppresses subsequent crop damage from the nutsedge-nematode pest complex

    Southern root-knot nematode [RKN, Meloidogyne incognita (Kofoid & White) Chitwood], yellow nutsedge (YNS, Cyperus esculentus L.), and purple nutsedge (PNS, C. rotundus L.) occur together as a mutually beneficial pest complex in sandy soils. All crops grown in infested soils are affected due to the wide host range of the nematode, the perennial life cycle of the nutsedges, their interactions, ...

  • Strategies to Successfully Manage Northeastern Apple Pests

    A wide range of pests threaten Northeastern apple crops, forcing some growers to spend up to 25 percent of production costs to manage mites, insects, disease and other pests. Practical strategies to help growers lower this huge cost while protecting their region’s $580 million annual apple crop are outlined in ...

  • Food security faces growing pest advance

    Coming soon to a farm near you: just about every possible type of pest that could take advantage of the ripening harvest in the nearby fields. By 2050, according to new research in the journal Global Ecology and Biogeography, those opportunistic viruses, bacteria, fungi, blights, ...

  • Integrating ecosystem services into crop protection and pest management: Case study with the soil fumigant 1,3‐dichloropropene and its use in tomato production in Italy

    Ecosystems provide the conditions for producing food, regulating water, and providing wildlife habitats; these, among others, are known as ecosystem services (ESs). Food production is both economically and culturally important to southern European farmers, particularly in Italy where farmers grow flavorsome tomatoes with passion and pride. Growers rely on pesticides for crop protection, the ...

  • Canola–Wheat intercrops for improved agronomic performance and integrated pest management

    Intercropping can enhance yields and reduce pest infestations, but investigations of intercropping regimes using crop species common to the large-scale monoculture production systems of western Canada have not examined these diverse elements. Intercrops of canola (Brassica napus L.) and wheat (Triticum aestivum L.) were established at three sites in Alberta, Canada in 2005 and 2006 to determine ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • 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 ...

  • Do cultivar and burning affect forage yield and incidence of verticillium wilt or insect pests in alfalfa stands?

    Alfalfa (Medicago sativa L.) is one of the most important forage crops in Canada and many parts of the world. Two experiments were conducted over a 13-yr period (1989–2002) in Lethbridge, Alberta, Canada with five alfalfa cultivars. In the first experiment, ‘Barrier’ and ‘Pacer’ were given three burn treatments (no burn, burn every year, and burn in alternate years) while in the second experiment ...

  • Asia–Pacific Analysis: Plan for growth in biotech crops

    South-East Asian nations should follow the Philippines down the path to biotech crops for food security, argues Crispin Maslog. Since biotechnology-derived crops were introduced in 1996, they have been adopted at an unprecedented rate, according to the 2011 annual report of the International Service for the Acquisition of Agri-biotech Applications (ISAAA) released earlier this year. ...

  • Studying the Effect of Global Warming on Tropical Crops

    Researchers have long been using impact studies to study the effects of climate change on cocoa growth. These studies mimic conditions predicted at the end of the century1 such as higher levels of drought and higher levels of atmospheric CO2. Studies have shown that increased levels of CO2 may help offset the negative effects of reduced water availability on the ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • 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 ...

  • Crop gene banks are preserving the future of agriculture. But who’s preserving them?

    As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate ...

  • The California rice cropping system: agronomic and natural resource issues for long-term sustainability

    California rice is produced on approximately 200,000 ha mostly in the Sacramento Valley. The crop is planted in April/May and harvested in September/October. The growing season is characterized by a Mediterranean climate with negligible rainfall, high solar radiation, and relatively cold nighttime temperatures, thus yields may exceed 9 t ha−1, 20% above the US average. California is a ...

  • Cassava: a promising food security crop in Mutomo, a semi-arid food deficit district in Kitui County of Kenya

    Cassava is ideal for production and provision of carbohydrates in the marginal and drought-prone areas, which comprise about 80% of Kenya. However, its potential utilisation as a food security crop remains low in these areas. A major constraint to cassava production is lack of adequate disease and pest-free planting materials greatly exacerbated by its low multiplication rate. The Kenya ...
