  • 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 ...

  • Bt-cotton boosts the gross margin of small-scale cotton producers in South Africa

    This paper explores some of the issues involved in the Genetic Modification (GM) debate by focusing on one crop that has been modified for pest resistance, cotton (Gossypium hirsutum), and commercially released to small-scale farmers in the Makhathini Flats, KwaZulu Natal, the Republic of South Africa. This was the first commercial release of a GM variety (Bt-cotton) in Sub-Saharan Africa, and ...

  • Economic comparison of transgenic and nontransgenic cotton production systems in georgia

    Transgenic cotton (Gossypium hirsutum L.) cultivars produce lint and seed and their propriety traits provide part of the crop's insect management and/or enable use of broad-spectrum herbicides for weed management. The standard procedures for conducting official cultivar trials utilize common pest management across all cultivars; whereas the pest management options and their associated potential ...

  • GM cotton and its possible contributions to environmental sustainability and rural development in Turkey

    Cotton farming in Turkey faces economic, environmental and socioeconomic challenges. Organic cotton has been a successful response that greatly benefited low-input farmers; but, worldwide, it will eventually become a mature niche market with limited growth potential. Since no Genetically Modified (GM) varieties have been approved so far in Turkey, we want to find out how the potential adoption of ...

  • 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, ...

  • The economic impacts of second generation Bt cotton in West Africa: empirical evidence from Burkina Faso

    West Africa has been slow in adopting agricultural biotechnology. The most progressive stance has been taken by Burkina Faso, which began field testing Bt cotton in 2003. This paper reports the first three years of Bt cotton field trials, which found that Bt cotton increased cotton yields by an average of 20% and reduced insecticide applications by two-thirds. While the technical success of Bt ...

  • Polyphagy and primary host plants: oviposition preference versus larval performance in the lepidopteran pest Helicoverpa armigera

    Oviposition preference and several measures of offspring performance of Helicoverpa armigera (Hübner) were investigated on a subset of its host plants that were selected for their reputed importance in the field in Australia. They included cotton, pigeon pea, sweet corn, mungbean, bean and common sowthistle. Plants were at their flowering stage when presented to gravid female moths. Flowering ...

  • Non-chemical Pre-plant Soil Disinfestation

    The battle with pests, diseases and weeds is an everyday problem for every farmer. Due to the fact that 40% of the world’s food production is lost due to pests and diseases, farmers need to manage crop protection. An excellent example of the need for pesticides is cotton. It is a crop that is affected by various pests. Cotton farming accounts for more than 25% of all insecticides and 12% of ...

  • Environmental dimensions of fertilizer and pesticide use; relevance to Indian agriculture

    This paper presents an overview of the environmental consequences of fertilizers and pesticides in agriculture and the measures needed to mitigate the adverse impact of these chemicals on environment. The issues are then analysed from the perspective of the use of fertilizers and pesticides in Indian agriculture. Fertilizer consumption in India is concentrated in about one-third of the cultivated ...

  • New tools and farmer training could revolutionize pesticide management in West Africa

    Field schools that train farmers in alternative methods of pest control have succeeded in nearly eliminating the use of toxic pesticides by a community of cotton growers in Mali, according to a new FAO study published today by the London-based Royal Society. The study was conducted in two areas - the Bla ...

  • Building a Safe Pesticides Industry with Bioproducts and Biomethods

    Three publications on my desk are the motivating factors behind this issue’s Compost Users Forum. The first is our own Compost Science & Utilization (Summer, l999), a journal that reports research throughout the world dealing with the process and product of compost making. The initial report in this issue is titled: “Prospects for Composts and Biocontrol Agents as Substitutes for Methyl ...

  • Indian government still ‘flip flopping’ on GM trials

    In August, India’s ruling nationalist Bharatiya Janata Party (BJP) stopped its legislators from accepting Monsanto sponsorship to attend a farm exhibition in the US state of Iowa. On the surface this might seem strange: attending the Farm Progress Show should be innocuous, as Monsanto routinely takes farmers, industry experts, media and MPs from various countries to visit the show and ...

  • EPA Releases Preliminary Risk Assessment for Neonicotinoid Insecticide Imidacloprid

    On January 6, 2016, the U.S. Environmental Protection Agency (EPA), in collaboration with California’s Department of Pesticide Regulation (DPR) announced the release of a preliminary pollinator risk assessment for the neonicotinoid insecticide, imidacloprid (Preliminary Risk Assessment or Assessment). In its assessment, ...

  • Can bats reduce nut farmers’ pesticide use?

    Ecologist Katherine Ingram is on a quest to quantify the economic value of insect-eating bats in walnut groves. For the past three years, Katherine Ingram has had a most unusual summer job: catching bats and studying their droppings to see what they eat. A doctoral student in ecology at the University of California, Davis, Ingram is exploring the role bats can play as winged ...

  • Controlling Barnyardgrass with Corn Hybrid Selection

    Barnyardgrass is a summer annual grass weed with a global impact on corn production.  Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • 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. ...

  • 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 ...

  • The developing world is awash in pesticides. Does it have to be?

    Herbicides, insecticides and fungicides threaten the environment and human health in many parts of the world. But research is pointing to a better approach. In today’s globalized world, it is not inconceivable that one might drink coffee from Colombia in the morning, munch cashews from Vietnam for lunch and gobble grains from Ethiopia for dinner. That we can enjoy these ...
