Refuge Roulette: Growers Defy Requirements

A significant percentage of U.S. corn and soybean growers are taking careful aim in preparation for shooting themselves in the foot.

Growers who opt to plant crops genetically modified (GM) with Bacillus thuringiensis (Bt) are required by federal guidelines to plant 20 percent of their fields with non-GM crops, establishing refuges to help delay development of pest insect resistance to Bt, as well as to protect the environment.

However, federal survey responses reported in 2002 revealed that more than 19 percent of farms growing Bt-corn in 10 midwestern U.S. states skirted federal requirements and either cut back the accepted refuge size, or didn't bother to plant them at all. These growers violated the requirement, were deemed to be noncompliant, or in plain words, cheated. That action that could have future consequences.

A noted entomologist long involved with developing rational management approaches to pest insects attacking midwestern corn and other crops exclaimed, "I was dismayed," by the federal noncompliance findings. "No wonder the general public is skeptical about our stewardship of products developed from biotechnology," he wrote in a recent newsletter.

Citing the latest data and the widespread violations of the refuge requirement, the Center for Science in the Public Interest (CSPI) urged the responsible federal agency to implement several actions: * obtain the most accurate data possible on refuge compliance; * require regular on-farm visits to assess compliance; * require growers to provide a certificate of compliance and map identifying Bt and non-Bt fields; * investigate with growers reasons for noncompliance and take action based on that information; * require registrants (the firms selling Bt crop seed) to devise strategies to reduce noncompliance, or face federal restriction of Bt crop seed sales.

IPM MEDLEY --- publications and other IPM information resources

A Muted Toot of the Horn

With a decade of uninterrupted monthly publication in hand, IPMnet NEWS and its sponsors, the Consortium for International Crop Protection (CICP), hopefully will be forgiven a rare spate of chest thumping.

In 1993, CICP Board members met to brainstorm the dual challenge of finding an avenue to continue the Consortium's long and productive efforts to foster global IPM development and adoption, but now without a traditional means of support. Creation of an electronic newsletter to communicate recent developments in IPM to an international audience seemed like a plausible and highly worthwhile option that capitalized on the emergence and accessibility of the Internet coupled with the fact that no other entity had stepped forward to provide what was deemed a potentially important service.

The endeavor was a gamble; what initially stumbled out of the gate as "Global IPM Information Service" (the not to memorable "GIPMIS") quickly morphed into IPMnet and inclusion of the monthly IPMnet NEWS, an embryonic website, and a slate of creative ideas for broadly disseminating IPM information. A search and salubrious circumstances connected CICP with a semi-retired agricultural technical editor with international newsletter experience, time on his hands, a suitably smudged keyboard, and a keen interest in tackling the challenge.

From inception IPMnet NEWS has spread, fungus-like, from an inauspicious initial distribution of just under 300 e-mail addresses 10 years ago to well over 3,000 e-mail subscribers today, plus uncounted web viewers and others who see pass-along files or articles from the NEWS picked up by other electronic outlets. While the wheels came off and sidelined numerous other IPM information vehicles for any number of reasons, IPMnet NEWS has trudged forward with intent to stay the course.

The NEWS owes it's continuation to a very supportive CICP Board of Directors led by J.D. Harper, the nurturing of R.E. Ford as CICP's executive director, and especially to the interest and tangible support from M.S. Fitzner, national program leader for IPM at the U.S. Dept. of Agriculture's Cooperative State Research, Education, & Extension Service. The encouragement and provision of a home and infrastructure for the NEWS by the director of Oregon State University's Integrated Plant Protection Center M. Kogan for many years (and a prime architect of IPMnet), and most recently P.C. Jepson has been incalculably valuable and the essential lifeblood of the effort.

Lastly, a very heartfelt salute and "thanks" is extended to all NEWS e-mail subscribers and website viewers. After all, there's commonality of interest in seeking more rational pest management approaches, but your continued readership of the NEWS is genuinely appreciated, valued, and critical to the global future of IPM.

PRACTICAL AQUATIC WEED GUIDE

A new, lavishly illustrated manual is a practical guide to the identification and biology of submerged, floating-leaved, and emergent aquatic weeds in rice production fields, water use systems, and wild land areas across the western U.S. With 442 pages, AQUATIC AND RIPARIAN WEEDS OF THE WEST is the first such comprehensive volume for the region and covers 171 aquatic plant species in 58 plant groups. Authors J.M. DiTomaso and E.A. Healy include full descriptions of 82 species and compare another 96 plants as similar species, representing over 40 plant families. The softbound, 2003 work includes: more than 560 clear full color photos; 17 shortcut identification tables to groups that share similar, unusual, or relatively uncommon characteristics; useful keys to floating-leaved and submerged aquatic weeds, pondweeds, and grasses or grass-like species; plus a glossary, and a bibliography with a handy "by genera" section. The landmark guide, Pub. #3421, was sponsored by the California Weed Science Society, and, while based on the western U.S., could be a valuable reference for other regions with similar aquatic plant species. *> ANR, Univ. of California, 6701 San Pablo Ave., 2nd. floor, Oakland, CA 94608-1239, USA. danrcs@ucdavis.edu .

CROP-SPECIFIC IPM AND ITS IMPACT

A regional collaborative project developed and validated a sustain-able IPM strategy for managing Leucinodes orbonalis (Guenee) (eggplant fruit and shoot borer), a primary pest of Solanum melongena L. (eggplant), one of the most popular and economically important vegetables among small-scale farmers and low income consumers in South Asia. Scientists from Bangladesh, India, and Sri Lanka worked with the Asian Vegetable Research and Development Center (AVRDC) to formulate a multitactic approach involving sanitation, use of pheromone traps, and reduction in pesticide use to encourage parasitoid activity. A 2003, softbound booklet, DEVELOPMENT OF AN INTEGRATED PEST MANAGEMENT STRATEGY FOR EGGPLANT FRUIT AND SHOOT BORER IN SOUTH ASIA, describes the process and favorable results. Authors S.N. Alam, et al, discuss each element of the strategy and present 25 figures, some in full color, as well as extensive tables. The 56-page work is Tech. Bull. #28.

A companion publication reveals the impact IPM adoption had on one region's eggplant growers. In SOCIO-ECONOMIC PARAMETERS OF EGGPLANT PEST CONTROL IN JESSORE DISTRICT OF BANGLADESH, M.A. Rashid, et al initially found that 98 percent of 100 eggplant farmers interviewed entirely relied on pesticides to control L. orbonalis, with more than 60 percent spraying their eggplant crop 140 times or more per season. Most sprayed everyday during the rainy season; pesticide cost was the single highest expense of production. Following demonstration of an IPM program sanitation, pheromones, and withholding pesticides those farmers adopting IPM reduced their labor and pesticide expenses, and had less reported illness. This softbound, 29-page monograph was published in 2003 as Tech. Bull #29, and includes both figures and tables.*> AVRDC, Communication/Training, PO Box 42, Shanhua, Tainan, Taiwan 741, ROC.

TOWARD BIOCONTROL QUALITY

An international aggregation of authorities on biocontrol agents contributed a mass of material that editor J.C. van Lenteren has neatly organized into QUALITY CONTROL AND PRODUCTION OF BIOLOGICAL CONTROL AGENTS, THEORY AND TESTING PROCEDURES. In the words of the editor, this timely, 2003 monograph addresses "a great need for quality control in the production and use of these natural enemies." In fact, the need for quality control forms the backbone of the first two chapters before various specifics of production and testing are discussed. But quality control, and how to best achieve it with biological organisms, is a repeating and constant theme throughout the 331-page work. In short, this welcome hardbound volume tackles a touchy, but clearly relevant issue and in doing so helps establish guidelines for mass producing biocontrol agents, an increasingly important tool for global agriculture. *> CABI Publishing, Wallingford, Oxford OX10 8DE, UK.CABI@cabi.org .

EARLY PHYTOBACTERIOLOGY

A collection of illuminating papers from the 19th and early 20th centuries highlight the pioneering research on plant disease conducted by T.J. Burrill, J.C. Arthur, and M.B. Waite. These three notable scientists established the fundamental concept that bacteria could cause plant disease and provided the first proof that insects acted as vectors of plant pathogens. C.S. Griffith, et al, have edited these milestone documents into the informative FIRE BLIGHT: THE FOUNDATION OF PHYTOBACTERIOLOGY, a 2003, all-text work. The 158-page, softbound monograph introduces fire blight, its history, and science, as well alluding to the "politics of a disease." A concluding chapter considers fire blight in the 20th century. *> APS Press, 3340 Pilot Knob Rd., St. Paul, MN 55121-2097, USA. aps@scisoc.org .Fax: 1-651-454-0766. Phone: 1-651-454-7250.

LIVELY BROCHURE INTRODUCES IPM

The entomology unit of the South Australia Research and Development Institute (SARDI) has published an attractive and informative brochure, "IPM, Integrated Pest Management." Using full color photos and a compact style, the 6-panel information piece aims to enhance "general community awareness about IPM in Australia," notes D. Jevremov, SARDI's IPM Adoption Co-ordinator. The intent, Jevremov says, "was to begin to broaden public knowledge about pest management in their vegetables, and also to introduce IPM to some growers." The text ranges from defining IPM, to citing its benefits, as well as covering basic tactics involved. A list of additional resources is included. The brochure states that IPM "is widely accepted as the modern approach to agricultural pest management." *> D. Jevremov, SARDI Entomology Unit, GPO Box 397, Adelaide, SA 5001, AUSTRALIA.

FEATURED PAPER

BASELINE FOR MEASURING IPM PROGRESS

The U.S. state of Washington is a major international producer of tree fruit (apple, pear, cherry), and as such, has a long history of intensive pest insect management in its orchards. A recent paper, "Pesticide Use and IPM in Washington's Pear and Cherry Orchards," by J.F. Brunner, et al, provides a comprehensive, data-rich profile of how a segment of pest management has evolved from highly traditional, i.e., nearly exclusive application of pesticides, to increased adoption of biocontrol, use of degree-day models, and allied IPM tactics. The authors surveyed growers in 1990 and again in 2000; the results, backed by actual on-the-ground comparisons, show a clear trend along the "IPM spectrum." The article, appearing in the August 2003 issue of AGRICHEMICAL AND ENVIRONMENTAL NEWS, #108, and on the web at aenews.wsu.edu ,includes numerous detailed tables (color coded for ease of use). The reported research stands as a useful example for gathering data to establish a baseline from which to measure future IPM progress.*> S.O.

Shampooing Grasshoppers

It may be a useful foaming agent for shampoos, but when sodium lauryl sulfate (SLS) in a purported insecticide optimistically named DeadSAFE! was liberally applied to Melanoplus packardii (grasshoppers) in Wyoming, it didn't phase them, reports extension entomologist S.P. Schell who observed the futile presentation of what was billed as a new, environmentally safe insecticide.

Schell and a colleague were invited to a field demonstration of DeadSAFE!, modestly claimed to be safe to everything except all insects at all stages. Not only were the sprayed hoppers still active 45 minutes after being sprayed, they showed no adverse signs 4 days later.

The DeadSAFE! label claims to be exempt from registration as its main active ingredient, SLS, is deemed a minimum risk insecticide. The SLS in DeadSAFE! is 0.109 percent, and inert ingredients are 99.89 percent; thus a US9.99 jug of DeadSAFE! concentrate would contain less than 0.2 fluid ounces of SLS. Other sources offer 29 percent SLS for a tenth the price.

The DeadSAFE! website www.lp (replete with misspellings and fractured grammar) is sponsored by LP-Products. The site also promotes Trinity Horse Shampoo; maybe it and DeadSAFE! share their chemistry. Ironically DeadSAFE! is billed as "a nontoxic insecticide" and "safe to use around aquatic systems" (possibly related to after-lather rinsing).

Schell advises to be alert to unsupported claims for insecticidal products. In the case of DeadSAFE! however, he points out that at least it is made from relatively harmless ingredients that are safe to both humans and grasshoppers. thanks to S.P.
