Useful Biofuel Species or Detrimental Weeds?
The majority of plants promoted as biofuels in Australia are also weedy species that definitely should not be cultivated, according to an extensive 2007 assessment published by the (Australian) Invasive Species Council (ISC).

THE WEEDY TRUTH ABOUT BIOFUELS, by T. Low and C. Booth, assesses the risks posed by 18 plant species being touted as promising biofuel sources and climate change solutions. Seven of the 18 species are currently banned as noxious weeds in various parts of Australia.

Two other promoted species,Spartinaspp. andArundo donax(giant reed), are included in the World Conservation Union's "List of 100 of the World's Worst Invasive Species." Still,A. donaxis currently being trialed as a biofuel crop in Australia despite the problems it causes as a "worst" weed worldwide.

Report senior author T. Low notes the gamble of "trying to solve one environmental problem by creating another." Mr. Low points out that many of the candidate biofuel plants "have no proven value as biofuel crops but bad reputations as weeds." In fact, many candidate biofuel species exhibit characteristics likely to exacerbate their weediness such as hardiness, drought tolerance, pest resistance, and a high level of competitiveness.

Yet, the weed risk of many species seen as biofuel sources appears to be ignored by policy makers, according to the Council which believes that any plant proposed as a source of biofuel should be thoroughly investigated and assessed for its weedy characteristics, potential for damage, and environ- mental impact. Taking a precautionary approach is deemed necessary and prudent.

The threat posed by many biofuel species is all the more ironic as Australia has ample experience with disasters following "blind enthusiasm for new industries and a blithe disregard for the consequences of introducing new species into the landscape," the ISC document warns.

ISC has developed a recommended list of nine key policy reforms to address the issue, all essentially built on a risk assessment base. The Council's report, seen as an important step toward eliminating ignorance of the problem, can be freely downloaded from the website www.invasives.org.au excerpted, with thanks, from the ISC website; thanks, also, to T. Low for information.

Biofuel and Biotech Plants Assessed
The Council for Agricultural Science and Technology (CAST), a U.S. entity devoted to communicating "credible, science-based information," recently published two papers bearing on crop pest management.

A CAST Commentary, "Biofuel Feedstocks: The Risk of Future Invasions," assesses the potential of biofuel crops for becoming weedy, invasive species and, while warning that such crops possess an ability to create economic and ecological damage through invasion of ecologically sensitive areas, suggests a multi-faceted process to both quantify and minimize this risk.

A second document, an Issues Paper entitled "Implications of Gene Flow in the Scale-up and Commercial Use of Biotechnology-Derived Crops: Economic and Policy Considerations," describes the nature of gene flow related to biotech crops and the conditions (said to be limited) under which economic problems can develop. The paper discusses regulatory, policy, and research factors related to gene flow of biotech crops.

Both documents were prepared by "an impressive group of scientists," according to CAST, and can be freely accessed in their entirety at www.cast along with CAST news release summarizations. excerpted, with thanks, from the CAST website.

GLOBAL BIOCONTROL ADVENTURES Eschewing a dry, purely academic format, editors C.H. Vincent,et al have deftly distilled 44 science-based contributions into 44 concise, informative "adventures" (their term) in BIOLOGICAL CONTROL, A GLOBAL PERSPECTIVE. The hardbound work, subtitled "Case Studies from Around the World," presents a realistic picture of scientific perseverance and tenacity yielding, in some cases, notable achievement, or conversely encountering disheartening impediments. The selected studies, contributed by a global contingent of scientists, have been edited into absorbing chapters devoid of jargon, stripped to the essentials, and often touching on the human, economic, and entrenched mindset realities of discovering, refining, and attempting to commercialize biocontrol systems. The 456-page, 2007 work includes a tipped in color multi-photo section as well as numerous black/white illustrations throughout. There are many publications on the biocontrol bookshelf, but for readers with an interest in biocontrol, a chunk of its history, and a taste for human and scientific adventure, this 2007 title stands out as a highly palatable and fascinating "read." {$} Customer Service, CABI, Wallingford, Oxfordshire OX10 8DE, UK. orders@cabi.org.

NUTRITION AND PATHOLOGY LINKED Mineral nutrients are vital in production agriculture/horticulture due to being critical as a first line of defense against plant pathogens. A 2007, peer-reviewed hardbound volume from the American Phytopathological Society, MINERAL NUTRITION AND PLANT DISEASE, discusses the multiple relationships of nutrition and pathology in extensive detail, a body of knowledge too often overlooked or misunderstood in the study and diagnosis of plant diseases. Editors L.E. Datnoff,et al incorporate both theoretical and practical information, in the latter case information for obtaining disease suppression with use of specific mineral-supplying fertilizers. Chapters are devoted to each of the key mineral elements and cite critical nutritional levels required, interdependent interactions, and other related factors. Some 40 color and black/white illustrations are scattered throughout the volume's 285 pages. The book is said to be the first "to successfully combine two important plant disciplines, nutrition and pathology." {$} -> APS Press. 3340 Pilot Knob Rd., St. Paul, MN 55121, USA.

THE AREA-WIDE CONCEPT AND PRACTICE Area-wide management of crop pests gained credence in the recent past to the extent it gradually migrated from headline news to established practice. As editors M.J.B. Vreysen,et al describe it in AREA-WIDE CONTROL OF INSECT PESTS, a 2007 compilation, the approach is notable for being "co- ordinated, sustainable and preventative" while targeting "pest populations in all areas" be they agricultural, adjacent, or non-agricultural. With its subtitle of "From Research to Field Implementation," this extensive hardbound volume pulls together 66 contributed papers by experts from more than 30 nations expounding on all facets of researching, developing, applying, and institutionalizing the area-wide approach, particularly directed against pest insect species. The editors add a unique dimension in that they all possess direct experience with sterile insect technique programs successfully applied in numerous instances. One quibble: while references from the introduction throughout the work's 804 pages utilize the widely accepted terminology of "area-wide IPM," or "AW-IPM," the title inexplicably uses the throwback term "area-wide control." With over 30 color illustrations and material never previously presented in a single source, the volume stands as a highly useful reference for the global IPM/crop protection community. {$} Springer, PO Box 17, 3300 AA Dordrecht, THE NETHERLANDS.

*WEB, PUBLICATION, CD/DVD, AND VIDEO NOTES*

IPMnet NEWS welcomes information for websites, publications, CD/DVDs, or videos focused on, or related to, crop or amenity plant IPM. Please send a review copy of the material to the address at end of this file; or, send the URL to: IPMnet@science.oregonstate.edu. A USEFUL BIOCONTROL INFORMATION TOOL

A group in NEW ZEALAND has created an informative website designed to provide an array of key facts, links, and needed elements to biocontrol researchers and practitioners planning to submit an application to introduce a new biocontrol organism into New Zealand. While obviously country specific, the 2007 site, "BIREA, Biocontrol Information Resource for ERMA [Environmental Risk Management Authority] New Zealand Applicants," www.b3nz.org can serve as a useful model and check list for similar situations and needs in other countries. The site addresses issues such as containment testing and requirements, release considerations, post-release monitoring, preparing for a public hearing, and other critical points necessary to ensure safety and minimize risks of escape and off-target problems. excerpted, with thanks, from the BIREA website; thanks to B.P.I. Barratt for information.

POTATO LATE BLIGHT TARGETED

Two European groups have joined forces to form the Potato Late Blight Network for Europe (EuroBlight). The intent is to focus onPhytophthora infestansand, through workshops and communication, devise effective integrated management systems. Topics addressed during a 2007 workshop ranged across decision support systems, host preferences, efficacy of fungicides, epidemiology, and the impact of what is labeled the 񓟶 epidemic." A follow-on workshop has been scheduled for October 2008. The organization's website, www.euroblight.net offers access to various reports, fungicide data, and links to other related resources. excerpted, with thanks, from the EuroBlight website.

IPM DEFINED, DEFINED, DEFINED ....

While it hasn't been modified in nearly a decade, "The Compendium of IPM Definitions" (CID) still arguably represents the single most extensive single collection of IPM definitions (over 60) as found in citations from literature published worldwide during a nearly 50-year period (1950-1998). CID, at ipmnet.org was collected and prepared by W.I. Bajwa and M. Kogan. The Compendium reveals the fascinating early development of the term "integrated," as applied to protecting crops from pest organisms, and its evolution into "integrated pest management," now globally recognized as the accepted standard in not only crop protection, but amenity planting, forestry, building/structure management, and just about any instance where humans seek to limit the extent and potentially adverse effects of undesired insect, plant, pathogen, or vertebrate species.

LIFE CYCLES AND NATURAL ENEMIES

A European firm has produced a series of DVDs on pest insects, the latest being "Whiteflies and their Natural Enemies." The DVD "movie" (PAL-formatted so may not be read by NTSC-format players) describes the life cycles of both whiteflies and their natural enemies, includes visuals plus spoken commentary (available in Dutch, French, English, German, or Spanish). The information was made available as an aid to understanding of the development and activities of pest insects' predators. Other current DVDs, besides the whiteflies title, focus on aphids and spider mites, with several other productions in preparation. The DVDs are available through Biobest N.V.'s global distributor network. See: www.biobest.be. thanks to R. Pauwels for information.

LAO LANGUAGE VERSION AVAILABLE

The Univ. of California's Small Farm Center now offers a newly produced video in the Lao language as a complimentary resource for the long-running PESTICIDE SAFETY FOR SMALL FARMS publication. There are also English, Spanish, and Hmong versions. The publication and videos employ visual aids to help small-scale growers follow safe practices in storing, mixing, applying, and disposing of pesticides.

*EQUIPMENT, PRODUCTS, PROCESSES, & SERVICES* ASSESSING PRESSURE GAUGE ACCURACY

One of the major sources of pesticide misapplication is faulty equipment such as worn nozzles or inaccurate pressure gauges. Devices for field testing nozzles are available, and now two U.S. Dept. of Agriculture specialists have designed and built a simple portable device for testing pressure gauges, the other important component. The device consists of a commercially available body and a factory-calibrated pressure gauge, a small water canister attached to a pistol grip handle, and a threaded port. Growers remove their gauge, insert it into the threaded port, fill the canister with water, squeeze the handle, and compare the pressure reading from the calibrated gauge with the reading from their gauge. If there is only a small variance, growers can safely continue to use their gauge and merely adjust spray pressure for the desired reading. But if the variance is significant, the faulty gauge needs to be promptly replaced. -> H. Zhu, Heping.Zhu@ars.usda.gov. Phone: 1-330-263-3871. thanks to D.

U.S. REGIONAL IPM CENTERS AND THE IPM-CRSP --- news, developments

Volunteer Multi-Trait Plants Pose Threat
Growers planting maize genetically modified with Bacillus thuringiensis to resist pest insects are well aware, or should be, of the need to include refuges of non-Bt maize to minimize the development of Bt-resistant insect pests. Entomologist C.H. Krupke asserts that there is another potential source for increased insect resistance, unwanted "volunteer" maize plants that emerge from seed produced by the previous year's crop. The increasing popularity of multi-trait (M-T) biotech maize varieties, which may include herbicide resistance, complicates conventional practice for eliminating volunteer plants. Dr. Krupke points to more M-T maize volunteers in the last few seasons and the fact that these plants, for some reason, do not express Bt at the same level as newly planted varieties, thus allowing insects to attack volunteer plants and be exposed to sub-lethal doses of the bacillus and eventually develop resistance capability. Volunteer maize, especially M-T plants, needs to be controlled as well as refuges maintained to stay a step ahead of pest insect resistance development, Krupke advises. -> C.H. Krupke, CKrupke@purdue.edu, excerpted, with thanks, from Ag Answers, 03 January 08.

Guide Profiles Insect Predators
A new publication, A POCKET GUIDE, COMMON NATURAL ENEMIES OF CROP AND GARDEN PESTS IN THE PACIFIC NORTHWEST, is self descriptive. A series of six-per-page panels depicts predators of literally garden variety pest insects, complete with full color, close up photos, identification points, observation tips (where and when to see these species), and a note on predacious activity. Author M. Ambrosino has added an extra feature, in most instances, of other species that may be similar in appearance or otherwise mistakne for the profiled predators. The Guide, intended to be printed on heavyweight paper or card stock and punched to fit a ring system, can be freely downloaded from tinyurl.com and should prove to be a handy tool, so long as "pests" in this case don't refer to weeds, vertebrates, or pathogens. -> M.
