IPM NEWS / APPLICATIONS international IPM news and programs Disease Grows into Worldwide Problem Ergot, once limited to Asia and Africa, has now become a serious global disease threat to sorghum (Sorghum bicolor [L.] Moench) with recent widespread epidemics in Brazil and Australia and appearances in several other Latin American nations. It continues to be a plague in numerous African and Asian countries, report the authors of "ErgotA Global Threat to Sorghum," in the INTERNATIONAL SORGHUM AND MILLETS NEWSLETTER (ISMN). A team of international scientists led by R. Bandyopadhyay present an extensive and detailed profile of a disease that can spread rapidly and has the ability to severely reduce grain yield. The authors recount that the 1995 epidemic in Brazil covered 800,000 square km. in a week, and, during a 3-week period in 1996, 60,000 square km in Australia. Ergot can be caused by either of two fungal pathogens. The disease can be spread by conidia that are wind-borne, carried by splashed raindrops, or moved by insects, as well as by clothing, footwear, and farm implements. Multiple cycles of infection can occur in the same growing season under certain conditions. Several options can be integrated in an ergot control program including sowing ergot-free seed, enforcing strict quarantine measures, adjusting sowing dates to take advantage of conditions that do not favor disease development, and removing other plants and litter to reduce sources of infection. A full color supplement to the original article contains clear close-up photos showing the disease's impact on sorghum.

Breeding Aimed at Cocoa Disease Black pod disease, caused by Phytophthora spp., is arguably the most devastating disease of cocoa plants (Theobroma cacao), an important tropical crop. Chemical control tactics, while available, are both costly and problematic, according to the French research organization, CIRAD (Centre de Cooperation Internationale en Recherche

Agronomique pour le Developpement). In his third edition of COCOA, published in 1975, G.A.R. Wood asserts that, "The replacement of susceptible trees by material showing durable resistance to the pathogen is the ultimate longterm solution to black pod losses." Following Wood's concept and to provide another tool for control, CIRAD has launched a genetic control research project being jointly conducted in Cote d'Ivoire and Trinidad. The approach uses molecular markers to analyze the genetic basis of resistance, identify early selection markers, and preserve the genes that confer cocoa with resistance to black pod disease. The research program in progress is built around: the genetic map of cocoa comprising 193 markers; analysis of population diversity of the responsible pathogen (showing variability within species of the genus Phytophthora); identification of sources of resistance; and, development of an early test on leaves.

IPM MEDLEY general information, publications of interest, and other information and resources related to IPM U.K. Council Expands Activities Long a presence in the U.K., the British Crop Protection Council (BCPC) more recently has been exerting an increasing international influence through an expanding range of activities. BCPC brings together a wide range of entities with interests in furthering the science and practice of crop protection: organizations representing research, corporations, education, government, small business, and overseas development. BCPC's primary objective is to "promote and encourage the science and practice of crop protection for the benefit of all." The Council pursues its objective by promoting independent and authoritative views through the means of conferences, symposia, publications, and other media. The general public, BCPC believes, should be exposed to a "balanced view on crop protection and its place in crop/food production." BCPC has taken over organization of the internationally recognized annual Brighton conferences (alternating between weeds one year and "pests" and diseases the next) as well as publishing and marketing an extensive list of titles through British Crop Protection Enterprises, BCPC's wholly owned commercial subsidiary. These uniformly well-produced, up-to-date works include proceedings, manuals, handbooks, and other titles. "Given the international nature of all important crop protection issues," says the Council, it has adopted a policy of enhancing its "relationships with like-minded crop protection organisations both within Europe and on a global basis."

QUOTES F.G. Zalom, Director of the Univ. of California Statewide IPM Project, on THE "INTEGRATION" IN IPM: "Integrated pest management is both a strategy and a philosophy for addressing potential pest problems. It is not a specific control tactic, although specific IPM-compatible tools to address key pest problems are often necessary elements of IPM systems. IPM requires an understanding of the ecology and economics of the production system being impacted by a pest species, as well as understanding of the biology of the pest species itself. "Non-chemical control approaches have been studied and used for many years, but the concept coalesced in the 1950s with the notion of `integrated control' which illustrated that using insecticides wisely so as to preserve naturally occurring biological control agents was a better long-term strategy than relying on pesticides alone. IPM expanded upon this concept of integration to include other pest control approaches in producing ecologically and economically based production systems. "IPM is not `insect pest management,' but necessarily encompasses the management of weed, pathogen, nematode, and vertebrate `pests' within an integrated production system framework. All of these pests face similar issues in terms of their damage potential, development of resistance to pesticides, and changing pesticide regulations brought about by possible environmental and health risks. "The research approaches and possible control tactics may differ by discipline, but IPM strategies apply to all. Integration of pest disciplines and of pest disciplines with production and social disciplines is vital to the development of IPM systems." excerpted with permission from: 1996 ANNUAL REPORT, UNIVERSITY OF CALIFORNIA STATEWIDE IPM PROJECT. J. Duffus, Research Plant Pathologist, on whitefly damage: "We're finding that whiteflies transmit close to 100 different diseases. Throughout the world, more crop damage is caused by these diseases than from the actual plant feeding of whiteflies." The British Agrochemicals Association (BAA), on IPM: "The goal in Integrated Pest Management is not to destroy every last weed, pest [insect] or disease in a crop but to keep infestations within bounds so that they do not cause economic damage to current or to future crops. "If any control treatment is needed, whether biological or chemical or a combination of both, it is only applied when a population reaches a damage threshold." "The growers' aim is to ensure the best yields of high quality fresh produce in the safest way and with minimal adverse environmental impact. They manage pest populations to keep them at levels which will not cause economically unacceptable damage.

"IPMthe techniques available to the farmer: Crop rotation; Cultivation(s); Use of resistant varieties; Better prediction methods of pest and disease attack; Encouragement of natural predators; More accurate diagnosis of pests and diseases infesting the crop; Target-specific crop protection chemicals; Biological pest control; and, Biotechnological methods." excerpted from BAA publications: CROP PROTECTION: THE WAY FORWARD; and, CROP PRODUCTION, WORKING WITH NATURE. IPMporium ..... Tests carried out to determine the activity of Cry 1 toxins from Bacillus thruringiensis against lepidoteran pests of maize showed that efficiency can vary 100-fold between species and that insect susceptibility differed with various toxins. ..... The U.K. Pesticide Guide plans to add an electronic version for its 1998 edition. ..... For Central American coffee plants, Meloidogyne and Pratylenchus nematodes pose one of the critical pest problems as they can cause up to 15-20 percent production losses.

International Pest Management Formerly known as "Tropical Pest Management," the periodical INTERNATIONAL JOURNAL OF PEST MANAGEMENT is alive and thriving under the editorship of Univ. of Wales scientists, N.A. Kidd and M.A. Jervis. The Journal, published by Taylor & Francis Ltd. in the U.K., covers "original research concerned with the control of pests and diseases of plants of economic, conservation, medicinal, and amenity value within the areas of agriculture, horticulture, forestry, conservation and stored products research." Interestingly, the publication excludes research on "pesticide development, formulation, and application methods and testing, unless presented in an integrated pest management context." FMI: N.A. Kidd, PO Box 915, Cardiff CF1 3TL, U.K. E-mail: Fax: 44-0-1222-874305 Pest Management in the Crosshairs Integrated pest management redefined to exclude pesticides is the subtext for a new softbound report published by Consumers Union (CU), a U.S. consumer advocacy organization. Within its attractive cover a print of an oil painting of a vineyard with a lush, low growing cover crop PEST MANAGEMENT AT THE CROSSROADS pulls no punches in forcefully presenting a raft of data and arguments to support adopting what it labels

biointensive IPM, or "high IPM." CU hired ag economist C.M. Benbrook, former executive director of the U.S. National Academy of Sciences' Board on Agriculture, to work with the CU hierarchy in preparing this 288-page work. On their way to the basic recommendation that, "The best way to lower pesticide risks is to reduce reliance on pesticides through a transition to bio-intensive IPM," the authors stitch together vignettes, numerous web site references, profiles of individuals, and practical examples of pest management (is putting lids on garbage cans in parks to avoid pest problems "biointensive?"). Entomologists may grimace at the page labeled "Bug Identification," but the volume's line drawings and graphs are well executed throughout and the publication's overall presentation crisp.

EQUIPMENT DEVICE MEASURES DEGREE-DAYS A series of automated, preprogrammed, microcontroller driven devices measure time and temperature and calculate degree-days for a wide variety of insect pests. The small (6.5 x 11.8 x 2.3 cm) weather-tight units, marketed under the TEMPEST label, are powered by a standard 9v. battery which is inserted at the time of placement in the field. Offered by Insect Investigations Ltd., a small highly specialized scientific firm in Cardiff, Wales, U.K., these devices are designed to predict pest outbreaks and to thereby target the optimum time to implement control practices. Manually activating a test button indicates status for the particular insect species being monitored. The manufacturer can tailor units for any of nearly 200 pest species found worldwide.

Pesticide is delivered in a 10 liter plastic container fitted with a special coupling that mates with a corresponding fitting on the tank of an application unit. Once engaged, the container is twisted to release pesticide into the tank.

The system assures "closed" transfer and controlled rate of release. The container is reclosed, removed, and returned for refilling. Farmers who tested LinkPak noted improved environmental and operator safety, more accurate measuring, and reduced wastage. FMI: Ciba Agriculture, Whittlesford, Cambs.
