IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs Universal Constraints to IPM Seven papers presented at the seminar on Institutional Constraints on IPM, held during the XIIIth International Plant Protection Congress in 1995, set forth a dismal litany of factors and arrangements that hamper wider adoption of IPM. This provocative mixture of case studies and insights now has been published as INSTITUTIONAL CONSTRAINTS TO IPM, edited by H. Waibel and J.C. Zadoks, and issued as no. 3 in the jointly supported Pesticide Policy Project's publication series. Among the studies, the aspect of research specialization that fosters a clearly non-integrated attitude toward IPM was cited as a major impediment to IPM. The role of donor agencies that have inflexible administrative procedures and self-interests can complicate the conduct of IPM programs, particularly in the country attempting to implement the activity.

Another viewpoint suggested the need for redefining the role of plant protection services from a "classical fire brigade mentality towards a concept of agro-ecosystems management." Also analyzed was the ultimate importance of political support and commitment which goes far beyond the usual rhetoric of public administrators.

State Launches Who's Who in IPM One of the United States' major fruit and berry producing states recently launched an ambitious project to develop a comprehensive directory of individuals statewide who are working to promote the use of integrated pest management. "Who's Who in Michigan IPM" is aimed at increasing cooperative efforts in IPM as well as identifying critical resources for improving IPM in Michigan. The completed director will be made available as an electronic database, a hard copy publication, and a WWW site.

The directory will include:

EDUCATORS who are teaching how to develop an IPM program and the use of IPM techniques; EXTENSIONISTS who are bringing new information and research to growers; RESEARCHERS in applied and basic research who are searching for new solutions and innovative techniques in IPM; CONSULTANTS whose services support growers and others in the use of IPM; SUPPLIERS who provide the materials and tools for implementing IPM; GROWER/PRACTITIONERS who participate in demonstration, research, or raising public awareness of IPM; and PUBLIC/PRIVATE AGENCY REPRESENTATIVES who provide funding or organizational support for IPM.

The directory is expected to be available in about seven to eight months. excerpted from: THE IPM REPORTIntegrated Pest Management in Michigan, 5(1), Spring 1996.

Biocontrol of Cassava Pests in Brazil Two phytoseiid species, Typhlodromalus tenuiscutus and Neoseiulus californicus, have been introduced into northeastern Brazil as part of the ongoing project, "Ecologically Sustainable Cassava Plant Protection in South America and Africa," sponsored by the United Nations Development Program and designed to develop biological control for major cassava pests. The objective: reduce losses caused by Mononychellus tanajoa, (cassava green mite - CGM) and Phenacoccus manihoti (cassava mealybug - CM) through introduction of predator mites, fungal pathogens, and insect parasitoids into small-scale cassava production systems in the semi-arid regions of northeastern Brazil. The program is based on collaboration between the Centro Internacional de Agricultura Tropical (CIAT) headquartered in Colombia and Empresa Brasileira de Pesquisa Agropecuaria (EMBRAPA).

Phytoseiid establishment has yet to be confirmed, but releases continue at several locations. This same classical biological control technique was used previously to establish three South American phytoseiid species in Africa to help control CGM on that continent. Project research workers are also pursuing several other elements of formalizing biocontrol in the region.

IPM Scout Training Held in Jordan Twenty IPM scouts from Jordan and the Palestinian Authority participated in classroom and field training during the first Integrated Pest Management (IPM) Scout Training course held 20-22 April 1996, at the National Center for Agricultural Technology Transfer and Training near Amman, Jordan. The course was conducted as part of the Jordan Valley Regional Integrated Pest Management Project, an activity sponsored by the International Cooperation and Development unit of the U.S. Department of Agriculture's Foreign Agricultural Service.

In early May, individuals involved with the human health component of the project travelled to Washington, DC, and met with scientists from various agencies to discuss general public health issues and human health concerns related to the use of agricultural production chemicals.

IPM MEDLEY --- publications and other IPM information resources

IV. IPM MEDLEY general information, publications of interests, and other information and resources related to IPM Asian Association Formed Industry representatives from throughout Asia met in Malaysia, concurrently with an International Pesticide Conference last April, and established the Asia-Pacific Crop Protection Association (APCPA), another in the increasing number of regional industry-oriented crop protection groups. Among the activities APCPA has pledged to support is "implementation of IPM including the safe, effective and judicious use of crop protection products where appropriate within an overall IPM strategy." It will also support implementation of the FAO International Code of Conduct on the Distribution and Use of Pesticides.

APCPA plans to continue programs launched by the International Group of National Associations of Agrochemical Product Manufacturers to develop education and expand training on the safe and effective use of crop protection products (CPPs) in compliance with the industry's safe use initiative.

According to an APCPA document, the Association was established "to help meet the food demands of a rapidly increasing population and, at the same time, the interests of the crop protection product industry working to meet these demands." APCPA joins other regional associations in Latin America, Europe, Africa-Middle East, Japan, and the U.S.

European Group Will Host Symposium The European Weed Research Society (EWRS) is one among the group of specialized international professional groups devoted to pest management. A key objective involves promoting weed research throughout Europe. Periodically the Society sponsors an international symposium. The 10th such meeting has been scheduled for June 1997 in Poznan, POLAND.

EWRS also assists with communication between weed researchers, and encourages the overall advancement of weed science and technology, according to the Society's stated objectives.

Managing Moles and Gophers In its usual thorough manner, COMMON SENSE PEST CONTROL (a quarterly publication) presents an extensive summary of the problems and various control methods associated with moles (vertebrate order Insectivora) and gophers, true rodents. Both are common, underground pests, though gophers are generally the more serious threat to plants. Backed by an extensive reference list, authors W. Quarles and L. Simon have gathered information on identification, trapping, and baiting. Control methods, when called for, vary according to site and situation. The article appeared in vol. XII(2), 5-15, Spring 1996, published by the Bio-Integral Resource Center (BIRC). FMI: BIRC, PO Box 7414, Berkeley, CA 94707, USA E-mail: BIRC@igc.apc.org Phone: 1-510-524-2567

Guide to Certain Pests in Tomato Fields Headed by a plant pathologist, a scientist-extensionist team in the U.S. state of Florida thoroughly revamped FLORIDA TOMATO SCOUTING GUIDE to help identify disease, nematode, and insect pests. The 1995 version (of its 12-year old predecessor) includes insect and disease identification keys, complete with a 16-page full color photo section. The text addresses action thresholds as well as field scouting procedures (but does not discuss weeds nor vertebrates). An interesting feature asks questions about careers in scouting (tomato fields) and offers answers. The 45-page, softbound publication, SP-22, by K. Pernezny, et al, contains a revised list of references and is said to have relevance to tomato growing areas beyond Florida that have similar climatic conditions.

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

II. RESEARCH REVIEW research and findings related to IPM. Research Profile: THE PACIFIC FORESTRY CENTRE MICROBIAL BIOCONTROL OF FOREST WEEDS PROGRAM An active research group within the Canadian Forest Service's Pacific Forestry Centre (PFC) is pursuing "integrated vegetation management" (IVM) with emphasis on microbial biological control of forest weeds. Headquartered at Victoria, British Columbia, the group has responsibility to research, select, develop, and refine biocontrol agents and processes that are sensitive to forest biodiversity and public concerns, as well as economically and physically feasible.

According to microbiologist C.E. Dorworth, "we are the single full program in the world directed entirely toward microbial biocontrol of native forest weeds with native pathogens." The one exception is Dr. Dorworth's new study to define indigenous pathogens and biocontrol strategies to control Scotch broom [Cytisus scoparius (L.) Link].

One estimate pegged crop losses in British Columbia due to weeds and their associated control costs at more than C million annually. The province began using natural enemies to control noxious grassland and pasture weeds in 1951. By 1993, over 50 biocontrol organisms had been released to control unwanted vegetation.

Among the laboratory's recent work is "Manipulation of Endophytic Fungi to Promote their Utility as Vegetation Biocontrol Agents," by Dorworth and mycologist B.E. Callan, to be included as chapter 11, in: ENDOPHYTIC FUNGI IN GRASSES AND WOODY PLANTS, SYSTEMATICS, ECOLOGY, AND EVOLUTION, edited by S.C. Redlin and L.M. Carris, and published in 1996 by APS Press.

III. TECHNOLOGY the nuts and bolts of IPM New Device Helps Control Trees A complete system utilizing biological agents to control unwanted hardwood tree species in managed forests has been developed by Canada's Pacific Forestry Centre (PFC). Originally developed to attack red alder (_Alnus rubraBong.), a species that, in many forest settings, readily crowds out young conifers being grown for harvest, the strategy of the PFC system is potentially useful for delivery of any biological or translocatable material into orchard, forest, or amenity trees. The patented system is built around the PFC-Mycocharge formulation and the PFC-Alderwak, a hand held tool that an operator uses to perforate a tree trunk and insert one or more biocontrol agent-impregnated pellets (PFC-Mycocharge). In the case of red alder, the biocontrol agent is Nectria ditissima, a pathogenic fungus specifically formulated as PFC-Alderkill.

Operation, while labor-intensive, can be economically justified for use in high value coniferous forests, or where public concern rules out other control methods. Killing takes about five years and may be completed by other fungi and insects. When the fungus is applied according to instructions, it is said to neither reproduce nor spread out of control. A full sales package was made available in 1996 to interested developers.

Rights to Med-fly Trap Acquired A U.S.-based international pest management products manufacturer has acquired rights to a dry trapping system developed by the U.S. Dept. of Agriculture (USDA) that attracts both male and female flies, including Ceratitis capitata (Wiedemann), the Mediterranean fruit fly. The system developed by R. Heath, a USDA researcher, uses a synthetic blend of attractants and colors to lure flies into a plastic cylinder where they become trapped. According to the manufacturer, Consep, Inc., traps are said to be easily assembled and maintained, and attractants are capable of lasting up to six weeks in the field. The product uses Consep's proprietary technology to control the release of the attractant over time.
