IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs U.S. IPM Goal Still Distant With only 18 months remaining, there will need to be an abrupt and dramatic shift in the USA's pest management practices if the nation expects to meet its announced goal "to implement IPM on 75 percent of all cropped acres by the end of the year 2000," noted H.D. Coble, national IPM coordinator for the U.S. Dept. of Agriculture, during a recent IPM conference. Coble presented "IPM The National Perspective" as a featured speaker at the regional conference, "IPM in Oregon: Achievements and Future Directions," convened in April 1999. The hard fact, he told attendees, is that 70 percent of the nation's crop land is planted to four major crops maize/corn, soybean, wheat, and cotton in which weeds are the predominant pest problem and where nearly 90 percent of the cropped area primarily relies on chemical management techniques. Clearly, he said, to have any hope of reaching the national IPM goal, efforts need to be focused on these crops that offer the greatest opportunities for reduced pesticide applications.

Approximately 50 percent of U.S. crop land currently falls in the categories of low to medium IPM along a spectrum ranging from zero to full participation. In terms of improved weed management and with an eye toward the 75 percent IPM goal, Dr. Coble cited four strategic approaches to realize expanded IPM: prevention, avoidance, monitoring, and suppression, embracing many of the following practices:

PREVENTION Use pest-free seeds or transplants; Remove alternate (pest) hosts; Clean equipment before moving between fields; Employ field sanitation measures. AVOIDANCE Rotate primary crops with other, non-host crops; Take steps to employ crop plant resistance; Use trap crops; Carefully select cultivars; Leave parts of fields unplanted. MONITORING Conduct surveys for pest infestations; Perform frequent, competent scouting; Keep thorough records, including weather data; Consider precision agriculture (global positioning); Use monitoring data to devise pest management tactics. SUPPRESSION Alter crop plant spacing; Change time of crop planting; Utilize tillage alternatives; Consider flame cultivation; Plant and maintain cover crops and living mulches; Use classical biocontrol; For chemicals, use the least toxic at lowest effective rate. Coble pointed toward a need to implement decision support systems with emphasis on detection, threshold-based remedial action, and a mix of suppression strategies, including judicious use of pesticides when necessary. The overall goal: stabilize pest populations below economically damaging levels while minimizing impact on the ecology. The vision is that wide scale adoption of IPM by growers will result in an economically viable, environmentally compatible, socially acceptable, and agriculturally sustainable production system. Among several objectives, Coble noted the vital necessity to insure availability of information and technology to growers, to measure adoption by growers, and to promote biologically intensive IPM.

Australian Group Looks Ahead With an eye toward the next century, the Australian Centre for International Research (ACIAR) has launched several international pest management-related initiatives designed to build on its notable existing record. Bemisia tabaci (whitefly), "one of the most intractable and devastating pests of vegetable and cotton industries throughout the world," according to authorities, feeds on, and damages, crops and can transmit crop diseases that, in certain situations, result in complete crop loss. To help address this global pest problem, ACIAR has lent its support to the internationally organized "CIAT-Systemwide Program on Integrated Pest Management: Sustainable Integrated Management of Whiteflies as Pests and Vectors of Plant Viruses in Asia." Via this link, ACIAR is supporting efforts to improve understanding of whitefly in Asia, determine its extent, and study the dynamics of the virus diseases it carries.

In the area of noxious weeds, ACIAR supports a program of "Improving Smallholder Farming Systems in Imperata Areas of Southeast Asia: Alternatives to Shifting Cultivation." Imperata cylindrica (L.), also known as "alang-alang," or cogongrass, enjoys notoriety as one of the "world's worst weeds," and is a particular problem in Asia.

Back in Australia, the Centre is working to develop electronic versions of many of the holdings in its extensive, 300-title publication list (monographs, proceedings, etc.) produced in recent years.

drawn from: ACIAR NEWSLETTER 33, June 1998-February 1999. GLOBAL IPM NOTES ## Research underway may lead to a special treatment for ordinary clothing that gives cloth the ability to reduce some pesticide droplets to inert particles on contact. The work, being conducted at the Univ. of California, involves the chemicals hydantoin and chlorine. When the treated fabric contacts certain pesticides, chlorine is released disinfecting the cloth and neutralizing the pesticide. The process would not be meant to replace impermeable clothing used during application, but could help protect field workers from lingering residues. > G. Sun, e-mail: gysun@ucdavis.edu. ## The understood rock-solid tenet that broccoli (Brassica oleracea var. botrytis) is healthful to humans because of providing glucosinates, recently took a direct hit from research revealing that broccoli, and other Brassica plants (cabbage, rapeseed, kale, mustard, turnips, radishes), remove bromide from the soil, convert it to methyl bromide (MBr), and release it into the atmosphere. Scientists also speculate that, beside Brassicaceae, there may be many other terrestrial plant families that produce and release MBr. That possibility factors into global efforts to reduce the agricultural pesticidal use of MBr, an identified ozone depletor. What it means for reducing human intake of broccoli and cabbage hasn't been addressed, as yet. > METH. BROM. ALTS., 2(2), April 1999.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general matters, publications of interest, and other resources for IPM information FAO Launches Information System FAO (Food and Agriculture Organization of the United Nations) has released the first edition of its ambitious new GLOBAL PLANT & PEST INFORMATION SYSTEM (GPPIS), an Internet-based version of an earlier compendium of worldwide plant protection information, that includes a free compact disc, an accompanying instruction booklet, and an invitation to contribute material to help expand the current database. Despite continuing to rely on the dated terminology of "plant protection" rather than contemporary idioms "crop protection and pest management," GPPIS is touted as a "learning system as well as a system for learning." It establishes a set of standard methods and protocols for data collection and sharing.

The interactive, somewhat quirky multi-media GPPIS is described as a "snapshot of the working system as it existed" in its web format on 14 July 1998, containing some 1,500 donated color images. Additional graphic materials and information are being actively solicited to both expand the range of information as well as improve older elements. It is said to provide access to 450,000 literature references and identity data for 11,000 plants.

The stand-alone application will run on both PCs (minimum: 486/66, CD drive, 16MB RAM, Win 95, SVGA) and Macintosh systems (minimum: Power PC/66, CD drive, 24MB RAM). Installing the CD loads a database engine and web server software necessary to enable a computer to emulate an Internet-based server, explain GPPIS co-architects C.A.J. Putter and M. Marsella. GPPIS is said to be compatible with a variety of Internet browsers.

According to the instruction booklet's preface, GPPIS is dedicated to the former head of FAO's Plant Protection Service, L. Chiarappa, "who consistently pushed for IPM to include an 'H' and become Integrated Plant Health Management," the authors note. While FAO conceived and developed GPPIS, it is said to be "owned by many people," and open to participation by many more.

WEED MANAGEMENT LINKED TO SOIL Focusing on weed management that emphasizes integration of techniques to anticipate and manage these problem plants such as prevention and reduction of weed emergence rather than reacting after they appear, INTEGRATED WEED AND SOIL MANAGEMENT offers an enlightened, highly constructive viewpoint. Editors J.L. Hatfield, et al drew on material delivered by an array of experts during a workshop to explore the obvious link between soil and weeds and the important relationships therein that can be exploited to arrive at greater sustainability, and less bombastic, but more effective, management. The 385+ pages of this 1998, hardbound work cover a variety of concepts that, taken together, point toward the "next generation of weed management systems." The only very minor cavil lies with the text's all-North American locus.

PEST MANAGEMENT HANDBOOK Loaded with factual information and suggestions for a variety of useful forms, the 1999 ILLINOIS AGRICULTURAL PEST MANAGEMENT HANDBOOK is a valuable information resource far beyond what it's single U.S. state title might imply. The softbound compendium's 346 attractively presented pages contain data sets and pragmatic crop protection suggestions ranging across a spectrum of crops and pests, all based on information provided by a diverse group of specialists. The very reasonably priced work represents an unusual bargain. FMI: ACES Information, T&C Services, 1917 S.

COVER CROP COMPENDIUM Increasingly, growers find that if moisture conditions permit, growing a cover crop offers multiple benefits, not the least of which may be weed, insect, and disease deterrence. But questions about which cover crop to grow and how to manage it successfully often sidetrack intentions. To the rescue (for augmenting that fescue) comes MANAGING COVER CROPS PROFITABLY in a revamped and expanded second edition. While focused on U.S. conditions, the 212-page, 1998 work offers a broadly useful series of informative charts comparing the pros and cons of 18 species when used as cover crops. The no-nonsense, softbound work includes numerous contacts, experts, and references to tap for additional information and assistance.

Publication & CD Notes An extension project in the USA has developed a useful form for scouting white mold; the informative overall approach and format, however, have potential to be adapted to a much wider range of pests. The 3-sheet form provides crop background information, field data, and an easily used scoring system leading to action recommendations. FMI: D.

For 1999 the well established journal BULLETIN OF ENTOMOLOGICAL RESEARCH has added "Critiques," a new section devoted to occasional articles of a critical and focused nature. These, the publisher says, "will not be exhaustive reviews of the literature, but will stimulate discussion and thought on the issues raised." A free descriptive brochure is available.

From mating disruption to strategies for halting insect invasions, the March issue (vol. 50, no. 6) of GOOD FRUIT bears a banquet of pest management related information. While those involved with western U.S. fruit orchard comprise the editorial target group, the broad selection of informative articles has wider interest such as: predicting insect population; fireblight management tactics; using sterile insect techniques; and getting started with a mating disruption program.

OTHER RESOURCES SCALE INSECTS INFORMATION A leading international authority on scale insects (Coccoidea) has developed "ScaleNet," an extensive website that offers comprehensive information about the insects' biology, classification, naming history, distribution, plant hosts, economic importance, and management techniques as well as links to relevant scientific literature. In collaboration with colleagues in Israel and Canada, D.R. Miller of the U.S. Dept. of Agriculture designed ScaleNet to make scale insect information widely scattered and tedious to locate in thousands of scientific publications readily accessible to growers, scientists, and homeowners at the website:

www.sel.barc.usda.gov/scalenet/scalenet.htm. Scale insects damage food, ornamental, fiber, and greenhouse crops causing serious economic losses each year. ScaleNet was conceived as an information tool to expedite identification, management, and prevention of problems related to scale insects. FMI: D.R.

EQUIPMENT & MATERIALS FORD HELPS FOIL FRUIT FIENDS In a twist on the long abandoned advert, "Is there a Ford in your future?," orchardists may soon find that there is a Ford in their foliage when an intriguing new device using an off-the-shelf Ford Motor Co. fuel injector nozzle to spray pheromones becomes available commercially. The Microsprayer, a device for controlled release of insect sex pheromones for insect mating disruption in orchards and eventually other economically important crops, has shown promise in early trials, according to scientists at Michigan State Univ., in the USA, where it was designed. In contrast to current pheromone release systems, the Microsprayer is said to be more durable, capable of releasing a mixture of pheromones instead of a single substance, and designed for reuse from year to year.

A Microsprayer unit comprises a nozzle assembly and a 9-volt battery-powered system that emits a burst of pheromone every 3 minutes (or as programmed), 24 hours per day, for an entire growing season. Units, weighing approximately 1 kg (2.3 lb), are placed in the upper third of the tree canopy, either hung from branches or at the upper end of poles, at a frequency of three per ha (two per ac). The pheromone material, which is tailored for either a single insect or more than one target species, is held in a replaceable attached canister, and protected against deterioration by oxygen and light.

IPM RESEARCH/TECHNICAL PAPERS --- categories and topics related to IPM

III. RESEARCH/TECHNICAL PAPERS research/technical topics related to IPM. IPMnet NEWS will gladly provide the postal address for any first author mentioned in the listed titles that follow. Please direct requests for this information via e-mail to: IPMnetNUZ@bcc.orst.edu. This Month's FEATURED PAPER Nearly three decades since the term "integrated pest management" (IPM) first appeared in print, the approach has become the paradigm of choice for attempting to moderate the impact of pests on crops, amenity plants, and public settings. In their broad overview, "Integrated Pest Management: A Global Reality?," scientists M. Kogan and W.I. Bajwa observe that despite IPM's conceptual acceptance, its practical application remains restricted. Within that context, this paper surveys both the status of, and static surrounding, IPM and the potential for its broad universal implementation. excerpted from: ANNL. SOC. ENTOMO.
