  • Grain legumes in northern great plains

    Cropping systems in the Northern Great Plains have shifted from fallow-based to legume-based systems. The introduction of grain legumes has impacted soil organisms, including both symbiotic and nonsymbiotic N-fixing bacteria, pathogens, mycorrhizae and fauna, and the processes they perform. These changes occur through effects of legume seed exudates, rhizosphere exudates, and decomposing crop ...

  • Effects of chlorpyrifos on life cycle parameters, cytochrome P450S expression, and antioxidant systems in the monogonont rotifer Brachionus koreanus

    Chlorpyrifos (CPF) is a widely used organophosphorus insecticide for controlling diverse insect pests of crops. In the monogonont rotifer Brachionus koreanus, population growth retardation with the inhibition of lifespan, fecundity, and individual body size of ovigerous females was shown over 10 d in response to CPF exposure. At the molecular and biochemical levels, the rotifer B. koreanus ...

  • A new pest in our crops

    Russian wheat aphid is now in New South Wales, having being discovered in South Australia two years ago in 2016. It has been discovered in a wheat crop in Coonabarabran that the owner has decided to put livestock on to it due to such a dry season and no hope of harvesting a crop. It was first reported by Sally Bryant – ABC Western Plains. The pest is manageable, though can affect up to 80% ...

  • A site‐specific ecological risk assessment for corn‐associated insecticides

    A site‐specific ecological risk assessment (ERA) was conducted to examine the simultaneous use of genetically modified corn (Bt corn) with a neonicotinoid seed coating, clothianidin, and use of a granular insecticide, tefluthrin, to protect crops from pest damage. A field study was conducted on‐site and exposure data from the literature was summarized to determine the matrices and exposure ...

  • Biotechnology for small-scale farmers: a Kenyan case study

    The paper analyses ex ante the potential economic effects of tissue culture biotechnology, which is being introduced into the Kenyan banana sector through an international collaborative project. The expected yield and income gains are sizable, because the pathogen-free banana planting material could substantially reduce the current crop losses induced by pests and diseases. However, using the ...

  • 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 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 ...

  • 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 ...

  • 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 ...

  • Behavioural and chemical ecology underlying the success of turnip rape (Brassica rapa) trap crops in protecting oilseed rape (Brassica napus) from the pollen beetle (Meligethes aeneus)

    There is increasing interest in the use of trap crops as components of integrated pest management (IPM) strategies. Understanding the mechanisms underlying host plant preferences of herbivorous pests can lead to improved effectiveness and reliability of the trap crop. We investigated the behavioural and chemical ecology underlying the success of turnip rape, Brassica rapa, trap crops in ...

  • 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 ...

  • An Assessment of Management Practices to Control Nutrient and Pesticide Levels in Vegetable Production Areas in the Rattaphum Catchment, Thailand

    The over-use of agrochemicals may have adverse effects on soils along with surface and groundwater. An assessment of alternative management practices to reduce the application of agrochemicals and minimise the pollution of water resources was carried out in the vegetable agro-ecosystem in the Rattaphum Catchment. This paper details the factors that govern the volume of agrochemicals used on high ...

  • 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 ...
