IPMnet NEWS January 2007, Issue no. 152 ISSN: 1523-7893 Š Copyright 2005 IPM NEWS --- international IPM news and programs Impacts of GM/GE Crops Assessed Two recent in-depth studies broadly assess the impacts to date of genetically modified/engineered crops: the first, from Switzerland, takes an ecological perspective, while the second considers the approaches of economic studies of GE crops as conducted in developing economies. The Swiss Expert Committee for Biosafety commissioned a far reaching, science-based study that resulted in a comprehensive paper published in late 2006 examining and documenting "Ecological Impacts of Genetically Modified Crops, Experiences from Ten Years of Experimental Field Research and Commercial Cultivation." Authors O. Sanvido,et al primarily utilized peer-reviewed materials from scientific sources in an effort to address questions about GM crop impacts and effects on non-target organisms, soil ecosystems, gene flow from GM crops to wild relatives, GM crop in- vasiveness, impacts on management on pest organisms, and ecological benefits of GM crop cultivation. Overall, the study concluded that available data do not provide any scientific evidence for harm to the environment attributable to commercial cultivation of GM crops. A minority of the Committee dissented from the study's conclusion. Additionally, the study's authors state that, "the real choice is between GM crops and current conventional pest .... management practices, all possibly having positive and negative outcomes," and that a truly precautionary policy requires comparing "the risk of adopting a technology against the risk of not adopting it."

Sanvido,

The second large study, also published in late 2006, is "Parables: Applied Economics Literature About the Impact of Genetically Engineered Crop Varieties in Developing Economies." This

work undertook an analysis of the methods employed to arrive at economic findings, as the methods themselves are clearly seen as influencing factors. Published by the International Food Policy Research Institute (IFPRI) as EPT discussion paper 158, the study concluded that, "findings of current case studies should not be generalized to other locations, crops, and traits" due to the relative short time frame of most analyses. Authors M. Smale,et alnote that "any particular variety, even if widely adapted, will perform with considerable variation across location and time." The 102-page study concludes that, "the net economic impact of new crop varieties on society is not easily measured" in that no single method can sufficiently measure change, particularly where so many markets, production environments, and policies can dramatically shift from one year to the next. Institutional and social contexts of technology introduction, the authors note, often have greater significance on impact direction and magnitude than the technology itself. Future studies on technology impact need to more critically assess effects in terms of labor, health, environment, equity, and poverty, the study's authors assert.

Smale, Axe Falls on Australian Weeds Center Weed and invasive plant research in Australia suffered a recent setback as the Cooperative Research Centre for Australian Weed Management (CRC4AWM) proposal for a new seven-year term beginning in mid-2008 was rejected by the Australian Dept. of Education, Science & Training that oversees the broad CRCs program. CRC4AWM, the sole weeds-only national entity in Australia, had proposed continuing to operate as the Invasive Plants CRC, given the critical importance of halting the prevalent spread of highly invasive plants on the island continent. Amidst an outpouring of support for the CRC4AWM from a cross section of Australian agricultural and other interests, the Centre has launched a website at to assist in fielding enquiries and to keep all interested parties advised. The rejected CRC proposal was said not to meet selection criteria on delivering returns to taxpayers, scientific capabilities, and capacity to commercialize research results and secure their uptake, and was based on both information in the organization's submitted application and independent assessment reports.


The Australian government's decision not to fund the 15+ year-old Cooperative Research Centre for weeds/invasive plants recalls events in the UK not so many decades ago. A relatively small group of highly dedicated scientists with great depth of experience and international acumen had established and nurtured what became the world renowned Weed Research Organization. Even with its minuscule budget, governmental entities decided the organization was not generating enough financial payback and, despite a global outcry, summarily shut down WRO. In one ill-advised move, the UK immediately forfeited its weed science leadership position and has not regained it to this day. Doubtlessly, there are many CRCs in Australia worthy of funding. The list of those successfully funded in the 2006 selection round (including seafood, railroads, hearing loss, capital markets, composite structures, biomarker translation, greenhouse gas, etc.) seems, at least to the outsider, thin at best if not woefully devoid of centers of excellence in agriculture pest and invasive organisms management. The struggle may not be over, but clearly the Australian government department with CRC oversight has demonstrated a predisposition for narrowly viewed economic gains as well as a disheartening disdain for stemming the tide of unwanted natural organisms that threaten both Australia's valued agriculture and the nation's recreational riches.

CARE AND HANDLING OF PESTICIDES Pesticide application authority and long-term head of the U.K.'s International Pesticide Application Research Centre, G.A. Matthews, has prepared a cogent, timely, and widely ranging treatise with PESTICIDES - HEALTH, SAFETY AND THE ENVIRONMENT. Building on how pesticides are used today, Prof. Matthews' narrative touches on the key points in the long-running debate over the use, advantages, and potential risks of pesticides. He includes graphic comparisons of spray application near human habitation, a dramatic contrast between properly and improperly attired spray application personnel, and the well establishedif infrequently followedsteps for conscientiously calibrating, operating, and cleaning application equipment. A single diagram in the 243-page, 2006 hardbound book's concluding section focuses on the future of pesticides and succinctly illustrates the factors, needs, and beneficial outcomes from adopting improved integrated pest management. {$} -> Blackwell Publishing Professional, 2121 State Ave., Ames, IA 50014, USA.

*EQUIPMENT, MATERIALS, & SERVICES* SPRAYER DESIGNED FOR RICE FIELDS A turbo-diesel powered, articulated, hydrostatic all-wheel drive, multi-use machine bears the name "MudMaster" and is specifically designed to effectively operate in rice fields. Primarily devised as a spray application platform, the unit can also be fitted with a rope-wick boom for direct-contact herbicide application, as well as several other configurations. With its articulating and pivoting center joint the MudMaster is said to negotiate the roughest mud and tallest levees while keeping all four tires firmly in contact with the ground surface. The manufacturer notes that the machine can handle application in areas where larger sprayers, due to heavy weight, or airplanes due to drift potential or obstructions, can not spray. The machine also is capable of all-weather operation and is said to cause minimal crop and field damage. -> Bowman Manufacturing, 2450 Jackson 36, Newport, AR 72112, USA. Phone: 1-870-523-2785.

Writing in the December 7, 2006 issue of PEST & CROP newsletter from Purdue Univ., J.L. Obermeyer,et al in a succinct article, "Rootworm Soil Insecticides: Choices, Considerations, and Efficacy Results," discuss each of four methods for delivering rootworm insecticide and caution that no one approach can nor will provide 100 percent control. The authors consider in depth and provide efficacy ratings for: insecticide-coated seed; liquids; granules; and transgenic (built-in) technology. There are benefits and drawbacks for each system dependent on a spectrum of variables, not the least of which may be a grower's existing application equipment.

A concluding piece of advice given is to include untreated or control strips in fields as a means to assess the performance, and economics, of rootworm products used. This, say Dr. Obermeyer and colleagues, is the only way to obtain an accurate evaluation of the performance and hence the value of a rootworm product. -> J.L.
