E. Africa Aims for Biopesticide Harmonization

Pesticide registration officers from five east African nations met recently in an effort to begin a process of harmonizing biopesticide registration requirements across the region and even beyond.

Representatives from DJIBOUTI, ETHIOPIA, KENYA, TANZANIA, and UGANDA gathered in Arusha, TANZANIA, to participate in a workshop and mock review of a biopesticide, an exercise designed to highlight the variations in how such a product would be treated according to differing national guidelines.

The group, whose ultimate goal is to develop guidelines that can be uniformly adopted throughout the region, committed itself to revising and unifying guidelines by September 2003. After review and revision, a single document will be presented for consideration by all member countries of the Southern and Eastern African Committee on Harmonization, a non-governmental organization comprising government regulators from countries spanning South Africa and Madagascar to Ethiopia.

Adoption of a uniform policy would help eliminate unnecessary barriers to registration of natural, environmentally friendly plant protection products, as well as enlarge and stabilize market potential, according to a press release from one of the workshop's sponsors. *> M.S. Rich, MRich@vt.edu. excerpted with thanks from the Afrik-IPM Listserv site, Afrik-IPM@listserv.vt.edu .

EC Backs Crop Co-existence

The European Commission (EC) recently published guidelines to help EC member states develop practical, workable strategies and best practices to ensure that genetically modified (GM) crops can successfully co-exist alongside conventional and organic crops.

The guidelines state the general principles, plus technical and procedural aspects, to be taken into account, and provide a list of possible actions that could be tailored for implementation at national, regional, or local levels. A press release (IP/03/1096) announcing the guidelines was dated 23 July 2003 and can be found at (multi-line address) europa.eu.int.rapid An EC official stated that, "We want to ensure that farmers are able to cultivate the types of agricultural crops they choose be it GM crops, conventional, or organic crops. This is why we need measures to ensure their coexistence. The recommendations are based on the latest available research results, and provide a sound basis on which member states should build their approaches."

The guidelines list a variety of measures that could be taken including: on-farm procedures including isolation distances, buffer zones, and pollen barriers (such as hedgerows); cooperation between neighboring farms (e.g., sharing information about sowing plans; use of crop varieties with staggered flowering times); providing training and advisory services for farmers; establishing monitoring and notification schemes; and, encouraging active information exchange efforts. thanks to Agnet July 24/03-II for information.

GLOBAL IPM: BITS AND PIECES

The Council of Australian Weed Science Societies and partners have endorsed formation of a physical weed control methods working group in AUSTRALIA to develop, apply, and promote strategies such asvarious tillage regimes, barriers, mulching, competition, and flaming. *> A. Bishop, Andrew.Bishop@dpiwe.tas.gov.au. Comparing maize grown in wheat straw mulch to maize growing over bare soil, researchers found: significantly lower Dalbulusmaidis (corn leafhopper) populations for up to a month following emergence; lower incidence of corn stunt disease; and, 25 percent higher yields. *> C.G. Summers, CGSummers@ucdavis.edu. Authors of a new pest management text present ample evidence that acarine biocontrol agents could be beneficially incorporated into IPM programs. *> U. Gerson, Gerson@agri.huji.ac.il. The U.S. Agency for International Development-funded IPM Collaborative Research Support Program, managed and led by Virginia Tech. (U.S.), recently received US.4 million for an 11th year of global activity. *> E.A. Heinrichs, IPM-dir@vt.edu .

PUBLICATIONS PERUSED (4 in this issue)

INSECTS AND TROPICAL FRUIT Insects, both harmful and beneficial, play a large role in the global production of tropical fruit. To address the interplay of the two groups and emphasize the role and increasing importance of IPM techniques in successfully managing pest insect populations, J.E. Pena and co-editors aggregated material from 28 international authorities to yield a timely new text, TROPICAL FRUIT PESTS AND POLLINATORS Biology, Economic Importance, Natural Enemies and Control. The hardbound volume's content is arranged in 13 chapters by crop or crop group and focuses on all critical aspects of the topic including the variety of management strategies deployed. The 2002 work includes a 16-page section of 90+ close-up color photos (but no other illustrations) in its 437 pages. *> CABI Publishing, CAB International, Wallingford, Oxon OX10 8DE, UK.

RESISTING NEMATODES' DAMAGE

An informally published 1990 manual (Host Resistance Committee of the Society of Nematologists) has been significantly expanded and augmented by a 2002 text, PLANT RESISTANCE TO PARASITIC NEMATODES, that describes methods for evaluating the resistance, and tolerance of, plant cultivars to the most devastating parasitic nematode species including cyst, root-knot, and reniform. Editors J.L. Starr, et al, and an international legion of contributing authors, discuss the concepts, needs for, and consequences of resistance, all with an eye to practical application. The 268-page, hardbound work includes 10 color plates and other illustrations across 13 nematologically organized chapters. The goal of the publication, notes Dr. Starr, "is to stimulate increased activity in the identification, characterization, development and employment of resistance to important nematode species." *> CABI Publishing (contact particulars as above).

ORCHARD PESTS PROFILED

A new, handy set of TREE FRUIT PEST IDENTIFICATION AND MONITORING CARDS is a "take-it-to-the-orchard" reference for doing just what the title says. The full-color, laminated 32-card pack covers pest insects, and mites, as well as several important diseases. While based on deciduous tree fruit and nut crops in California, the information presented by authors C. Pickel, et al can have far wider use. Each pest is identified by a description and close-up photos of important life stages. The peer reviewed information is applicable for both growing and dormant seasons. Management data is not included, but references to the relevant management and control documents stressing IPMare. Each 13 x 8.9 cm. (5.25 x 3.5 in.) card is printed on both sides. The pack was published in 2003 as ANR Pub. #3426. *> ANR, Communication Svcs., Univ. of California, 6701 San Pablo Ave., 2nd Floor, Oakland, CA 94608-1239,USA. Fax: 1-510-643-5470.

WHEAT: INSECT PESTS AND DISEASES

A 135-page, illustrated field handbook, WHEAT DISEASES AND PESTS: A GUIDE TO FIELD IDENTIFICATION, published by the International Maize and Wheat Improvement Center in 1986, has been more recently recast into an HTML version by others (with permission) and is found at: wheat.pw.usda.gov . The original was designed "as a quick guide for identifying wheat and triticale diseases in the field," plus insect pests, nematodes, and physiologic and genetic disorders, according to the preface. While a lot of grain has been harvested since the Guide first saw the light of day, a large portion of the information is still useful, especially the list of symptoms that lead directly to discussions and (somewhat grainy) photos of specific disorders. Regrettably, weeds receive zero attention.

HERBICIDE RESISTANCE

The Queensland Department of Primary Industries offers THE NORTHERN HERBICIDE RESISTANCE REPORTER, a periodic web-based multi-page newsletter covering regional research and developments concerning herbicide resistance (wwwweeds.crc.org.au ). The very colorful and graphically appealing publication includes material on many aspects of herbicide resistance, an increasingly troublesome occurrence. The newsletter is hosted by the website of the Cooperative Research Centre for Australian Weed Management.*> M.

DEVICE AIDS PITFALL TRAP USE Pitfall traps are commonly used to sample arthropods that travel on the ground. A trap is usually some sort of small container (often a vial) buried up to its rim in the soil. The process of extracting a container from the soil can be difficult when the soil dries around it, not to mention having to stoop or kneel down at each trap site and risk brushing unwanted soil into the trap during removal. Two researchers engineered a device that overcomes the problems and allows for fast, safe removal. In their paper, "A Simple Device to Assist with Pitfall Trap Sampling," FLA. ENTOM., 86(1), 94-95, March 2003, J.T. Vogt and D.K. Harsh, describe a low cost pitfall trap container retriever constructed from tubing and a few inexpensive bolts. Squeezing a trigger lifts a threaded rod that in turn compresses a round rubber head inside the trap. Friction holds the trap while it is extracted, and without any loss or entry of soil, or need for bending over or kneeling. *> J.T. Vogt, JVogt@ars.usda.gov .

FEATURED PAPER

Kaolin Film Deters Bollworms The last few years have witnessed increased possibilities for incorporating kaolin particle film into programs for protecting crops against pest insects. In recently reported lab and field studies, M.S. Sisterson, et al, found that when Gossypium hirsutum (cotton) bolls were treated with kaolin film the result had an overall deterrent effect on Pectinophora gossypiella (pink bollworm). In their paper, "Effects of Kaolin Particle Film on Oviposition, Larval Mining and Infestation of Cotton by Pink Bollworm (Lepidoptera: Gelechiidae),"the authors conclude that the film, in conjunction with other management tactics, may effectively hinder P. gossypiella and thus contribute to control of this serious insect pest of cotton. excerpted with thanks from JRNL.

Weed Science Site Offers Multiple Choices

The weed science group at the Univ. of Illinois has launched a lively website, "Weed Science," at weeds.cropsci.uiuc.edu . Not only are there items of interest broadly specific to Illinois, (e.g., 2003 ILLINOIS AGRICULTURAL PEST MANAGEMENT HANDBOOK freely available for downloading in PDF format), but universally useful information such as "Utilizing Herbicide Site of Action to Combat Weed Resistance to Herbicides," another free PDF file of wide interest. In addition there is a weed photo gallery with dozens of full color plates and extensive accompanying information.

The new website pulls together material on research, extension, and teaching as well as resource and reference items. The latter, in turn, leads to a wide selection of links ranging from other university weed science web pages to industry sources and professional societies.
