Groups Create Soybean Rust InfoCenter

A coalition of private and public sector organizations has taken a positive step forward in the battle against the globally spreading fungal pathogen Phakospora pachyrhizi [(Asian) soybean rust] 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 find information about identification and management of soybean rust, as well as links to university and extension sites with more detailed data. There is an additional searchable soybean rust image database, plus soybean rust distribution maps and identification training materials.

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

Recent arrival and subsequent rapid spread of P. pachyrhizi in the continental U.S. provided impetus for creating the centralized site, a development whole-hearted welcomed by numerous crop-oriented societies, land grant universities, and agribusiness organizations. thanks to M. Wimer and A. Steigman for information; excerpted with thanks from PMN/APS documents and sites. GLOBAL IPM SNAPSHOTS

Climate Change, Crops, and Pests

As if the inter-relationships between plants, pest organisms, and the existing environment weren't staggeringly complex, the onus of potential global climate change bodes yet further complications of the fragile equation.

Viewing climate change as a looming challenge, two scientists have polished their trusty crystal ball and ventured into the future to predict the implications of multiple environmental changes on biotic interactions. S.G. Pritchard and J.S. Amthor, in their 2005 book, CROPS AND ENVIRONMENTAL CHANGE, address the effects of global warming, increasing atmospheric CO2 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 enhance weed growth relative to crops; Being highly adaptable, many weed species can be expected to rapidly and more effectively adapt to increasing stresses such as rising atmospheric O3 and soil salinization; Warming trends most likely will also increase abundance, growth rate, and geographic range of many key crop-attacking insect pests; Warming may, depending on shifting precipitation patterns, stimulate microbial pathogens; Crop tissue chemistry, including nitrogen and water content as well as inducible defense mechanisms, is likely to evolve as environmental change occurs; On the plus side, rising CO2 may stimulate rhizobia and my corrhizae and benefit both 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 "that crop plants are not the only organisms determining yield that are likely to be affected by environmental changes." The authors warn that generalizations about magnitudes of effects and whether they will be deleterious or beneficial for crops are still in the realm of conjecture due to a lack of experimental data. But the prospects and potentials discussed are thought provoking. Web: HaworthPress.com excerpted, with thanks to the authors and publisher, from: CROPS AND ENVIRONMENTAL CHANGE, Food Products Press.

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

In 656 pages, the first volume, NEMATODE MORPHOLOGY, PHYSIOLOGY AND ECOLOGY, incorporates 12 chapters covering the historic foundation of modern nematology as well 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 biological control agents of pest insects and other invertebrates is discussed in the 608-page second volume as is the cost-benefit element of nematode management via regulatory programs. An overview of nematicides past and present is also included.

Taken together the set, by "a veritable who's-who in entomopathogenic nematology," according to the Society of Nematologists, constitutes an invaluable reference. *> CABI Publishing, Wallingford, Oxfordshire OX10 8DE, UK. orders@cabi.org.

The battle against invasive plants gained another useful resource recently with publication of BIOLOGICAL CONTROL OF INVASIVE PLANTS IN THE UNITED STATES, a productive collaboration of more than 60 authors representing over 20 institutions including several outside the U.S. The 476-page publication covers both key terrestrial and aquatic plants and suggests a science-based approach to an integrated strategy for managing invasive flora, primarily through biocontrol. Editors E.M. Coombs, et al, address a variety of factors affecting performance (or lack thereof in some cases) of biocontrol directed at invasives. A second section focuses on 39 target plants in the U.S. (many well known globally), as well as 90-plus bioagents deployed against the targets. For each plant the attractively organized volume succinctly summarizes nomenclature, biology, and the nature of infestations. Numerous lush full color photos, many of the "before and after" genre, supplement the text. Published in late 2004, the softbound work importantly sets forth and discusses a set of 12 well thought out guidelines offered as an International Code of Best Practices for Classical Biological Control of Weeds. All royalties from 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.

Several field trials conducted by Asian Vegetable Research and Development Center (AVRDC) scientists showed that pheromone-baited traps effectively attracted and controlled Leucinodes orbonalis (Guenee) (eggplant fruit and shoot borer) (EFSB) and minimized a need for pesticides. Use of the baited traps, employing a blend of compounds commercialized in Asia, also was found to be more cost effective than using pesticides. An electronic 20-page brochure by F.C. Su, et al, HOW TO USE SEX PHEROMONE FOR CONTROLLING EGGPLANT FRUIT AND SHOOT BORER, subsequently was prepared in 2004 to illustrate specific procedures for trap use. The publication, found at: www.avrdc.org includes large type and numerous full color photos. *> N.S. Talekar, Talekar@avrdc.org.

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 a range of procedures involving adjusted application timing, in-row herbicide banding, and leaving weeds between rows. The results, as reported in "Management of Genetically Modified Herbicide-tolerant Sugar Beet for Spring and Autumn Environmental Benefit," reveal that revised weed management of GM sugar beet (in a geographic zone where moisture is not a constraint) not only incurs no yield loss, but enhances weed seed banks, and provides (weed) seed for wild birds and invertebrates. *> M.J.

New Version of Extensive Guide Issued

The latest weed management publication resulting from a 2-state collaboration is the 2005 WEED CONTROL GUIDE FOR OHIO AND INDIANA, a comprehensive, revised reference for producing row crops and forages. The recently published Guide contains over 170 pages of weed management information for corn, soybeans, sorghum, wheat, alfalfa, grass pastures, and rangeland. It lists common weeds found in Indiana and Ohio, herbicides labeled for use on those weeds, and includes special sections on herbicide resistance, plus a listing of various glyphosate products available for use in Roundup Ready (TM) soybeans and corn. The 170-page work includes more than 20 information tables covering a variety of weed management topics. The Guide (Ohio State Bulletin 789, or Publication No. WS16) can be freely downloaded from: ohioline.osu.edu A printed version can be ordered by calling: 1-614-292-1607. @ Small Orchard Pest Strategy: Unsatisfactory

Orchard crop damage caused by Cydia pomonella (codling moth) occurs in small, private plantings just as it does in commercial ventures where expensive, time consuming moth management programs can usually be justified. To determine the effectiveness of a simpler system that might be suitable for small-scale orchards, extension specialists in California devised, investigated, and reported on, "Control of Codling Moth in Backyard Orchards with Last Call 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 was not sufficiently effective, consistent, nor justified for use by homeowners (all master gardener volunteers in this case) who were disappointed in the results which failed to meet their expectations.*> P.M.
