– It is the first global map on farm insecticide runoff made by computer modelling

– Forty per cent of land has water bodies at risk of such harmful runoff

– The map highlights exposure hotspots where action should be focused

The global threat that insecticides pose for aquatic biodiversity has been revealed in a recent modelling study that pinpoints areas at greatest risk. The mapping exercise conducted by the researchers reveals that aquatic life in water bodies within 40 per cent of the global land surface is at risk from insecticides running off the land. Published in Environmental Pollution last month (30 December), the map of potential insecticide contamination hotspots could assist freshwater management and conservation efforts as it highlights areas where damage mitigation should be concentrated. One researcher behind the study, Matthias Liess, from the Helmholtz Centre for Environmental Research in Germany, explains that tropical and subtropical regions need to pay urgent attention to threats of biodiversity loss from insecticide use. Farmers in many developing countries are changing from subsistence farming to market-oriented intensive crop farming, the study notes. “It is very helpful for environmental risk assessment and environmental management to have the information on insecticide occurrence on the landmass of countries. We can then identify where to find exposure hotspots, and where it is most relevant to plan mitigation measures,” adds Liess. Mitigation methods include buffer strips, alongside water bodies which are free of insecticide use, says Liess, who also suggests more efficient environmental management to combat the risk. The study used existing maps and databases such as the UN Food and Agriculture Organization’s data on country use of insecticides, to produce a global map showing runoff vulnerability, or how likely it is that rainwater will run off the land into water bodies based on the slope of the terrain and rainfall; and the runoff hazard related to the amount of insecticide used. The two are combined into a global insecticide runoff map showing how much insecticide is likely to contaminate water bodies. “There is a huge lack of information on everything related to agriculture and insecticide usage,” says Meirelles. The FAO has warned that some developing countries are using insecticides that are banned in developed countries, he adds. “But there’s a catch: countries such as Brazil have a larger biodiversity than other countries and this will always lead to more pests,” Meirelles says. “Without proper data, resources and political will, we cannot provide more useful information and improve management efforts.” Political will is key for mitigation, he says, because high insecticide use is often related to valuable agricultural exports from Brazil and other countries. > Link to the abstract in Environmental Pollution

Rice Pests of Bangladesh provides a comprehensive coverage of all of the abiotic constraints to rice production in the field and of pests in storage. The quality of this publication is enhanced by the fact that it brings together the accumulated data and experience of the two authors over the last 30 years. The 14 chapters and 422 pages cover all aspects of rice pest management including pests, yield loss, major control strategies and rice IPM.

Chapter 1 is entitled “Bangladesh and Rice.” Chapter 2 discusses the concepts of rice growth and pest status. Chapters 3-7 cover the early vegetative insect pests, general defoliators, stem borers, sap feeders and minor invertebrate pests. Chapter 8 discusses the vertebrate pests; rodents and birds. Chapter 9 provides a comprehensive coverage of the rice diseases; fungal, viral, bacterial and nematodes. The major weed species, their ecology severity and management are covered in Chapter 10. Chapter 11 explains the concepts of yield loss including mechanisms, plant compensation and yield loss assessment methods. Pests of rice in storage including insects, fungi and rodents are explained in Chaptger 12. Provides a detailed coverage of the major control strategies including cultural control, plant resistance, biological control and chemical control and pesticides. Chapter 14 covers the IPM of rice pests; concepts, principles, current management systems and new concepts for IPM in Bangladesh rice production.

This profusely illustrated book with an underlying IPM and ecological approach takes a fresh look at yield losses from insects and diseases and contains a wealth of information for rice plant protection specialists. It is specifically targeted to students, teachers, researchers, extension officers and agricultural development workers. The value of this book is enhanced as the information therein is not only relevant to Bangladesh but also applies to the Indian states of West Bengal, Assam and Bihar.

Farming Life

19 April 2014



Representatives of the Water Catchment Partnership local shows and events to deliver one message incorporating the ethos from all organisations to effectively tackle the problem of pesticides in the water environment particularly in Drinking Water areas and to promote best practice.


The Ulster Farmers’ Union are pleased to announce that the Voluntary Initiative have launched a new Integrated Pest Management Plan (IPMP).

Tim McClelland representing the UFU on the VI commented: “The NFU have been instrumental in developing this tool for the farming industry ensuring it is user friendly and effective. There is a requirement under the Sustainable Use Directive for Member States to encourage the uptake of Integrated Pest Management (IPM).

“The European Commission defines this as economically and environmentally sustainable management of pests, weeds and diseases using cultural, chemical, physical and biological controls.”

To meet this new requirement the UFU welcomes that the UK Regulators have recognised that our farmers do actually carry out a wide range of these practices. The adoption of an agreed voluntary approach to demonstrate IPM as opposed to regulatory approaches has been well received within the industry. To satisfy this requirement the new IPM plan for the VI is available and can be accessed at http://www.voluntaryinitiative.org.uk/ipmp

The new IPM plan for the VI will replace the original VI Crop Protection Management Plan (CPMP). This new IPM Plan is user friendly and will help demonstrate and record good practice. The Voluntary Initiative illustrates how good practice can convince Government that voluntary approaches are better than any regulatory one.

Changes to Current Rules on Grandfathers Rights for Pesticide Users

A current exemption for Pesticides users in UK law is commonly known as “grandfather rights”. This exemption will continue until 26 November 2015. After this date everyone who uses plant protection products authorised for professional use must hold a certificate of competence.

Option 1- Is the Existing Certification route.

Option 2 – Is the New Level 2 Certificate in the Safe Use of Pesticides for those farmers who have been operating under “Grandfather Rights”. The New Level 2 Certificate work booklet can be found at the link: http://www.nptc.org.uk/qualificationschemedetail.aspx?id=474

To help gauge industry demand and ensure sufficient resources are made available to meet this important industry need please register an expression of interest at http://www.cafre.ac.uk/2014/03/grandfathers-rights/ you can also contact Industry Training Administration team by email industry.trainingadmin@dardni.gov.uk.

The Water Catchment Partnership

Representatives of the Water Catchment Partnership established in 2013 met recently to progress plans for attending the 2014 RUAS Balmoral Show. The Partners promote the importance of proactively working together to raise awareness of best practice when using pesticides in the garden or on the farm.

Over the past year the Water Catchment Partnership representatives have attended and hosted a series of events with visits in the pilot Derg Catchment area.

Stop and think about the water you drink – use pesticides responsibly.

Integrated pest management gains momentum due to European regulations on pesticides reduction. But the challenges are to integrate all alternative methods and to get farmers involved.

Reducing the level of pesticide use in agriculture is a priority in Europe. A 2009 EU Directive states that the use of pesticide must be compatible with sustainable development. In particular, it encourages so-called integrated pest management (IPM) initiatives. IPM consists in combining available biological, genetic and agricultural methods to fight pests—such as weeds, bacteria, viruses, insects and fungi – rather than using extensive pesticide spraying.

Now the EU-funded PURE research project, due to be completed in 2015, aims at providing practical IPM solutions to reduce dependence on pesticides in selected major farming systems in Europe. “Our final objective is to provide farmers a toolbox for implementing IPM,” says Françoise Lescourret, director of research at the plants and cropping systems in horticulture laboratory at the French National Institute for Agricultural Research (INRA), in Avignon, France. She is also the project coordinator.

The research focuses specifically on six cropping systems: wheat and maize as field vegetables, as well as pomefruits and grapevine as perennial crops, and tomato as greenhouse crop. Field tests are carried out in ten European countries. Project scientists are testing several solutions including, for example, the phasing of sowing in response to pest emergence, the use of plant species resistant or tolerant to biological aggressors, and the release of predator insect species in greenhouses.

Alongside these existing methods, the project team also evaluates innovative technological solutions, such as air samplers that can warn the arrival of airborne inoculum of pathogens, or mating disruption for insects involving the release of pheromones.

Then, IPM models taking into account experimental results are designed in the lab, and tested back in the field, in a virtuous circle. “Combining IPM solutions is challenging as all problems do not arise at the same time in farms,” Lescourret tells youris.com.

Assessing the cost of these solutions before and after implementation is also a key point of the project. “A good [integrated pest management] solution results in a positive environmental impact, a good cost-versus-benefit ratio, and preserves the social well-being of agriculture professionals,” she tells youris.com.

Economic aspects are indeed crucial. “In order to execute IPM, many more economic thresholds for pest, disease, and weed infestation are needed. Economic thresholds are the levels of the pest that will cause economic loss if the pest is not controlled. Controlling the pest below this level is wasteful, costly and a totally unjustified use of pesticides. In order to assess if a pest is above this threshold, farmers needs more sampling methods to measure the pest level. PURE can add to their toolbox” says Richard Meadow, research scientist at Bioforsk, the Norwegian Institute for Agricultural and Environmental Research, in Ås, Norway.

However, a toolbox is not enough, for Hans Muilerman, pesticides & alternatives officer with PAN Europe, the European subsidiary of pesticide action network federating environmental NGOs. “The main thing farmers need is good examples. If the ‘hero’ of the region adopts IPM, many will follow. Governments should start ‘IPM-hero’ programs and stimulate it. A toolbox is only needed when farmers feel like changing and this is the big hurdle for now,” he tells youris.com.

By the time the project reaches completion, however, the European network ENDURE for the promotion of sustainable agriculture will take over and spread the results among agricultural advisers to maximise the chance that project findings will be implemented.
