IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news, and application of IPM techniques and programs. IPM Certification Program Expands The U.S. State of Massachusetts' IPM Certification Program, "Partners With Nature," completed its third year of operation in 1995, with a 32 percent increase in participation over 1994. IPM certification is based on the use of best management practices including: soil and nutrient management; disease management; insect management; weed management; pesticide application and records; and education. In 1995, 68 qualifying crops including strawberry, sweet corn, potato, cole crops, and tomato grown on 37 farms were IPM certified.

IPM certification is based on a point system that weights production practices according to their difficulty and their importance to management. Practices are documented with written records where practical. Partial credit can be earned by completing a percentage of an appropriate practice. A crop can be IPM certified when a grower verifies that 70 percent of the possible IPM practices were followed.

Program sponsors feel that the point system has a number of advantages. It lists all of the best management practices available to the grower. Growers then have the flexibility to select and design the most appropriate IPM system for their particular farm conditions. Use of the most desirable practices is encouraged by assigning them more weight. Allowing partial credit prompts growers to try new techniques.

All farmers who enroll in the certification program are provided with educational materials. Qualifying growers are licensed to use the "Partners With Nature" logo and are provided with marketing assistance including posters, brochures, and documents that prove their crop is IPM certified. The program is also associated with the U.S. Dept. of Agriculture's (USDA) federal cost-sharing program, so that growers meeting certification requirements are eligible for cost-share funds.

The Massachusetts IPM Certification Program is jointly administered by the Univ. of Massachusetts Extension, the Massachusetts Dept. of Food and Agriculture, and the USDA Farm Services Agency.

IPM Program in Sudan Broadened The long running FAO/Government of Sudan IPM project, funded by the Government of the Netherlands, has recently opened an Integrated Pest Management Research and Training Centre at Wad Medani. The new building can accommodate regional IPM research and training activities for nations in the region. The collaborative IPM effort, now known as the FAO/ARC IPM Project, began in the late 1970s and has significantly reduced the use of pesticides, primarily in Sudanese produced cotton. Phase IV of the program began in 1993 and is primarily devoted to IPM in vegetable crops.

The successful use of `farmer field schools' in Asia to implement IPM has been adopted in Sudan in close partnership with several governmental departments. Both the Univ. of Gezira and Univ. of Khartoum are contributing to Phase IV. More than 30 extensionists, entomologists, plant physiologists, and weed scientists are assigned to the project, according to the report of the program's 1995 annual review and planning meeting.

The report notes that, "national support for the IPM project is tremendous," and that Farmers Unions are "very supportive." During 1995, Sudan's IPM Steering Committee has been transformed into a permanent National IPM Committee.

Study Looks at IPM for sub-Saharan Africa A study summarized in a late 1994 report provides, among other elements, an insightful and thorough review of the complexities of implementing IPM in African agriculture. The document, BILATERAL DONOR AGENCIES AND THE ENVIRONMENT: PEST AND PESTICIDE MANAGEMENT, by R.J. Tobin, reviews sector assistance offered by five major donors (France, Germany, Japan, UK, and USA) and examines the donors' policies of the designed to promote agricultural trade or production in sub-Saharan Africa. Varying approaches and attitudes among donors toward provision of pesticides and support for IPM, as well as cultural impediments and diverse national considerations, are cogently set forth in a direct manner. The conclusion Dr. Tobin reached is not entirely positive nor are the answers to a series of critical questions always encouraging.

The study, prepared for the Office of Sustainable Development, within the U.S. Agency for International Development's Bureau for Africa, drew upon extensive contacts with key individuals representing organizations in each of the five donor nations. The inescapable reaction to this study is that Tobin has cut through the dialog and developed a factually-based, balanced overview.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general information, publications of interest, and other information and resources related to IPM. Insect Research Center Marks 25 Years The International Centre of Insect Physiology and Ecology (ICIPE) has published a full color retrospective pamphlet, ൡ Years of Research in Tropical Insect Science." The text and numerous photos document the Centre's quarter-century of progress from a concept and modest beginnings to a modern research organization recently reshaped to address key scientific issues in the tropical developing world. According to the text, ICIPE has renewed its mandate to "serve as a force to alleviate world poverty and to ensure food security and good health for the peoples of the tropics through management and control of both harmful and useful arthropods."

In late 1994, Swiss scientist and 1995 World Food Prize laureate H.R. Herren was appointed ICIPE's director general. Dr. Herren observed that, despite progress, the future challenge of pest management in the tropics is daunting.

ICIPE has now "reoriented its research agenda toward areas long neglected in Africa and to a lesser degree in the tropics as a whole," Herren noted in the Centre's 1994 annual report. One new thrust will focus on horticultural crops (vegetables, fruits, and ornamentals) because these plants are the target of so many arthropod pests and the site of major pesticide abuse because of high market value and cosmetic requirements.

U.S. Wildlife Research Relocates Wildlife research in a new U.S. federal facility was scheduled to begin in 1995 with initial emphasis on development of attractants and repellants leading to new, effective, and acceptable wildlife management methods. The new U.S. National Wildlife Research Center (NWRC) is being phased in on the campus of Colorado State Univ. at Ft. Collins, in the state of Colorado. The present facilities the Denver Wildlife Research Center (DWRC) will be closed when its research functions are incorporated into the NWRC. The Center's Research programs focus on resolving problems resulting from human/wildlife interaction.

One of the more prominent programs involves bird strikes to commercial and military aircraft which cause many million dollars in damage and occasional loss of human life. A current project underway seeks to quantify the magnitude and nature of bird strikes to aircraft nationwide. Another effort, in progress at DWRC's Ohio field station, is investigating responses of birds and small mammals to various grass management regimes at one of the nation's busiest commercial airports, Chicago's O'Hare International Airport. The objective is to provide information that could help minimize the population of gulls, starlings, hawks, and waterfowl through reducing the factors that serve as attractants.

A program to evaluate a collar worn by sheep to deter coyote predation found that the device, when punctured, did release a deterrent substance, but which only temporarily halted the attack.

Another effort continues to research various immunocontraception techniques for both mammals and birds.

An international thrust covers a range of activities including reduction of blackbird damage to rice in Uruguay, and management of the brown tree snake (BTS) on Guam. The threat in the latter case is BTS introduction into other Pacific islands which could trigger a similar ecological disaster. On Guam, the BTS, a species accidentally introduced via cargo following World War II, has extirpated several species of indigenous birds, caused numerous power outages, and has bitten infants and small children.

excerpted from: DWRC RESEARCH UPDATE, Fall 1995.

IPMporium ..... Scientists at the International Rice Research Institute (Los Banos, Philippines) are experimenting with using the Bacillus thuringiensis (Bt) gene as a "built-in" protectant against one of the most damaging insect pests of rice, the yellow stemborer [Scirpophaga incertulas (Walker)]. Seeds of transgenic rice containing the Bt gene were supplied by Ciba-Geigy through the Swiss Federal Institute of Technology in Zurich. ..... In recent months the destructive cocoa pod borer (Acrocercops cramerella) has affected more than 40,000 hectares of cocoa land in Sulawesi, Indonesia's main growing region.

..... In 1996, U.S. producers will have access to genetically altered corn seed that incorporates a gene from the Bacillus thuringiensis, or Bt soil bacteria, that, according to research conducted at Iowa State Univ., provides safe, effective control of Ostrinia nubilalis (Hubner), European corn borer, without reducing yields.

..... Four entities that have adopted techniques to increase the benefits and reduce the risks of pest management were honored as "IPM Innovators" by the U.S. State of California in the second year of a joint state-federal government awards program. The honorees included a nursery, a growers' association, and two governmental organizations.

..... Japanese pest management scientists have established a national IPMnet link for information sharing and product development.

..... A noted world authority predicts that food security will outrank military security in parts of the world in coming years because of ever tightening food supplies and upwardly spiraling prices.

Pesticide Policy Guidelines One of the more recent publications in the "Pesticide Policy Project Series" (PPPS) is GUIDELINES FOR PESTICIDE POLICY STUDIES: A Framework for Analyzing Economic and Political Factors of Pesticide Use in Developing Countries, by S. Agne, et al. Elaborating on material developed at an FAO Panel of Experts on Integrated Pest Control (1994), the 27-page work aims to establish a general methodological framework and "to facilitate inter-country comparisons and to raise the level of transparency of pesticide policy studies." The premise is that several factors contribute to the sluggish adoption of IPM, key among them a lack of knowledge of the factors that influence the use of "chemical" pesticides. The PPPS arose from a belief that the current use of pesticides exceeds a level that is acceptable to society. For more information, contact: H.

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

III. FORUM / EDITORIAL viewpoints, opinions, and discussion of IPM issues. I, P, and M: Three Familiar Letters When combined, those three ordinary letters have evolved into a critically important international approach to improving crop production and simultaneously decreasing a threat to the environment and human welfare. "IPM" not only is shorthand for Integrated Pest Management, but an acronym that's now synonymous with advancement in the way humans are attempting to cope and coexist with other species that compete for space and food in the universe. While "pest" and "management" seem relatively straight-forward and unambiguous, how did they come to be preceded by "integrated?" Who, in fact, coined the phrase that is now nearly universal? Here is one possible scenario. Readers with other information are invited to offer their insights and comments.

The burgeoning post World War II economy of the western U.S.'s biggest agricultural state, California, led to an explosion in agricultural production. With increased land brought into production, there came the inevitable upsurge in insects, weeds, and other pest species that posed problems both real and perceived. The clamor from consumers first and then producers for immediate, effective control methods led to expanded chemical control, supplanted to ever lessening degrees by other practices.

Visionaries began to warn of the implications of reliance on, and over-use of, chemicals. A few researchers focused on biological control techniques and their potential benefits, but were not ready to offer assured, deliverable methods to commercial growers. A group of entomologists from two Univ. of California branches began to investigate augmenting one form of control with another. One of the earliest published research papers in this vein was "The Integration of Chemical and Biological Control of the Spotted Alfalfa Aphid: The Integrated Control Concept," by V.M. Stern, R.F. Smith, R. van den Bosch, and K.S. Hagen, in HILGARDIA, 29(2), 81-101, October 1959.

"With adequate knowledge," these pioneers observed, chemical and biological control can augment one another. "Integrated control combines and integrates biological and chemical controls. Chemical control is used as necessary and in a manner which is least disruptive to biological control. Thought must be given to biological control of not only the primary pest under consideration but also other potential pests," they noted.

Stern et al concluded that, "Integrated control is most successful when sound economic thresholds have been established, rapid sampling methods have been devised, and selective insecticides are available."

The concept later shifted from one of "control" to one of "management" and grew from only referring to pest insect species to include the numerous weed species that were and are economically devastating pests, as well as diseases, nematodes, and vertebrates.

The architects of what we now know as IPM were clear: the approach they developed was intended to be integrative, resourceful, and sensitive to prevailing conditions, not necessarily exclusionary, and certainly not limiting. Their nearly four-decade old legacy should benefit mankind well into the future.

IV. RESEARCH REVIEW research and findings related to IPM. Energy-efficient Weed Management A team of Canadian scientists conducted energy audits for conventional and alternative weed management systems and found that most alternative methods of weed control (e.g. reduced herbicide and tillage inputs) are more energy efficient than conventional weed control practices broadcast application of herbicides at recommended rates. The experiments, conducted in Ontario Province, revealed that energy was conserved by eliminating or reducing tillage and reducing or eliminating herbicide application. Eliminating tillage was more energy efficient than eliminating herbicide. Also, low-input systems were more efficient in converting energy into crop yield than high-input systems, provided substituted inputs were used in moderation.

In the Ontario trials, modifications in fertilizer use were more important for energy conservation than weed management because the latter represented only 20-25 percent of the annual energy cost for systems using "synthetic" herbicides and fertilizers.
