IPM NEWS --- international IPM news and programsGroups Create Soybean Rust InfoCenter

A coalition of private and public sector organizations has taken a positive step forward in thebattle against the globally spreading fungal pathogen Phakospora pachyrhizi [(Asian) soybeanrust] by creating a comprehensive, freely accessed on-line soybean rust information center,www.plantmanagementnetwork.org (click icon).

The site includes current news on soybean rust; links to featured soybean rust sites government,national, international, and university; a soybean rust database that can be used to findinformation about identification and management of soybean rust, as well as links to universityand extension sites with more detailed data. There is an additional searchable soybean rust imagedatabase, plus soybean rust distribution maps and identification training materials.

The Plant Management Network (PMN) and the American Phytopathological Society (APS) ledthe way in establishing the soybean rust information site as an efficient entry point and clearinghouse for accessing dozens of soybean rust related websites scattered all across the web. Usefulinformation from numerous sources has been, and continues to actively be, aggregated in thissingle central site.

Recent arrival and subsequent rapid spread of P. pachyrhizi in the continental U.S. providedimpetus for creating the centralized site, a development whole-hearted welcomed by numerouscrop-oriented societies, land grant universities, and agribusiness organizations. thanks to M.Wimer and A.

IPM MEDLEY --- publications and other IPM information resourcesClimate Change, Crops, and Pests

As if the inter-relationships between plants, pest organisms, and the existing environment weren'tstaggeringly complex, the onus of potential global climate change bodes yet furthercomplications of the fragile equation.

Viewing climate change as a looming challenge, two scientists have polished their trusty crystalball and ventured into the future to predict the implications of multiple environmental changes onbiotic interactions. S.G. Pritchard and J.S. Amthor, in their 2005 book, CROPS ANDENVIRONMENTAL CHANGE, address the effects of global warming, increasing atmosphericCO2 and O3 concentrations, and soil salinization on crop physiology and yield.

With a specific focus on major classes of crop pests, Drs. Pritchard and Amthor suggest that:Warming may favor most weeds in comparison to crops; Rising CO2 also is likely to enhanceweed growth relative to crops; Being highly adaptable, many weed species can be expected torapidly and more effectively adapt to increasing stresses such as rising atmospheric O3 and soilsalinization; Warming trends most likely will also increase abundance, growth rate, andgeographic range of many key crop-attacking insect pests; Warming may, depending on shiftingprecipitation patterns, stimulate microbial pathogens; Crop tissue chemistry, including nitrogenand water content as well as inducible defense mechanisms, is likely to evolve as environmentalchange occurs; On the plus side, rising CO2 may stimulate rhizobia and my corrhizae and benefitboth crop plants and soil dwelling symbionts; Warming (soil) may be beneficial in some regions,but harmful in those regions where optimal soil temperatures already exist.

There is much more intriguing information to support Pritchard and Amthor's contention "thatcrop plants are not the only organisms determining yield that are likely to be affected byenvironmental changes." The authors warn that generalizations about magnitudes of effects andwhether they will be deleterious or beneficial for crops are still in the realm of conjecture due to alack of experimental data. But the prospects and potentials discussed are thought provoking.Web: HaworthPress.com excerpted, with thanks to the authors and publisher, from: CROPSAND ENVIRONMENTAL CHANGE, Food Products Press.

CONTEMPORARY SURVEY OF NEMATOLOGY

A comprehensive, hardbound 2-volume set published in 2004 surveys NEMATOLOGYADVANCES AND PERSPECTIVES: Advances Achieved in the 20th Century, and perspectivesfor ongoing development of nematology in the foreseeable future. Editors Z.X. Chen, et al, havedrawn on a cadre of internationally recognized nematologists to contribute a multitude ofinformation that not only chronicles the journey and contribution of nematology, but addressesthe complexities of nematode management in an environment of shifting options.

In 656 pages, the first volume, NEMATODE MORPHOLOGY, PHYSIOLOGY ANDECOLOGY, incorporates 12 chapters covering the historic foundation of modern nematology aswell as basic biology aspects such as nematode biodiversity, population dynamics, and behavior.Volume 2 homes in on contemporary nematology, the characteristic parasitism of plants,humans, and other animals, and critically management methodology. Their use as biologicalcontrol agents of pest insects and other invertebrates is discussed in the 608-page second volumeas is the cost-benefit element of nematode management via regulatory programs. An overview ofnematicides past and present is also included.

Taken together the set, by "a veritable who's-who in entomopathogenic nematology," accordingto the Society of Nematologists, constitutes an invaluable reference. *> CABI Publishing,Wallingford, Oxfordshire OX10 8DE, UK. orders@cabi.org. Phone: 44-0-1491-832111. Fax:44-0-1491-829292. Web: www.cabi

BIOCONTROL AIMED AT INVASIVES

The battle against invasive plants gained another useful resource recently with publication ofBIOLOGICAL CONTROL OF INVASIVE PLANTS IN THE UNITED STATES, a productivecollaboration of more than 60 authors representing over 20 institutions including several outsidethe U.S. The 476-page publication covers both key terrestrial and aquatic plants and suggests ascience-based approach to an integrated strategy for managing invasive flora, primarily throughbiocontrol. Editors E.M. Coombs, et al, address a variety of factors affecting performance (orlack thereof in some cases) of biocontrol directed at invasives. A second section focuses on 39target plants in the U.S. (many well known globally), as well as 90-plus bioagents deployedagainst the targets. For each plant the attractively organized volume succinctly summarizesnomenclature, biology, and the nature of infestations. Numerous lush full color photos, many ofthe "before and after" genre, supplement the text. Published in late 2004, the softbound workimportantly sets forth and discusses a set of 12 well thought out guidelines offered as anInternational Code of Best Practices for Classical Biological Control of Weeds. All royaltiesfrom sales of this book will be donated to the (U.S.) Western Society of Weed Science. *>Oregon State Univ. Press, 102 Adams Hall, OSU, Corvallis, OR 97331-6407, USA. Fax:1-541-737-3170.

GM Crop Weed Management Benefits Wildlife

Concerns over possible negative environmental consequences of genetically modified (GM)crops for wildlife in the UK led to four field trials with herbicide-tolerant sugar beet over 2 years.Weed scientist M.J. May, and colleagues, compared conventional weed management with arange of procedures involving adjusted application timing, in-row herbicide banding, and leavingweeds between rows. The results, as reported in "Management of Genetically ModifiedHerbicide-tolerant Sugar Beet for Spring and Autumn Environmental Benefit," reveal thatrevised weed management of GM sugar beet (in a geographic zone where moisture is not aconstraint) not only incurs no yield loss, but enhances weed seed banks, and provides (weed)seed for wild birds and invertebrates. *> M.J.

Orchard crop damage caused by Cydia pomonella (codling moth) occurs in small, privateplantings just as it does in commercial ventures where expensive, time consuming mothmanagement programs can usually be justified. To determine the effectiveness of a simplersystem that might be suitable for small-scale orchards, extension specialists in Californiadevised, investigated, and reported on, "Control of Codling Moth in Backyard Orchards with LastCall CM (Permethrin and Pheromone in a Paste Formulation)." P.M. Vossen and A. Devarenne,reporting the trial results in UC PLANT PROTECTION QUARTERLY (UCPPQ)www.uckac.edu concluded that use of Permethrin and pheromone dispensed in paste form wasnot sufficiently effective, consistent, nor justified for use by homeowners (all master gardenervolunteers in this case) who were disappointed in the results which failed to meet theirexpectations.*> P.M.
