IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs U.S. IPM Program Budget Proposed Key elements of the United States government's IPM Initiative program, whose goal is IPM implementation on 75% of all U.S. crop acreage by the year 2000, are proposing a US0 million budget for fiscal 1996 and an increase to nearly US5 million in fiscal 1997, according to an official fact sheet issued in mid-April 1996. The IPM Initiative, notes B.J. Jacobsen, IPM Coordinator for the U.S. Department of Agriculture (USDA), reflects a new approach by redirecting and combining both current and new resources. Various agencies of the USDA, along with Land-grant university programs, farmers, private consultants, and industry, are now cooperating in a coordinated, broadly supported effort focused on resolving major pest management challenges and striving to attain the national IPM goal.

The National IPM Initiative is built on a logical progression of: needs assessment; development of knowledge and technology; implementation; feedback; and accountability. The latter involves data collection to document the economic, environmental, public health, and social impacts of IPM adoption.

One piece of the overall IPM effort involves a three-phase competitive research and extension grants program. Twenty-three teams of growers, consultants, research and extension staff, plus state and federal agencies, formed all across the U.S.in 1996, identified priority research, education, and technology transfer needs, and developed implementation plans for specific production regions.

In the next phase, these teams will submit their cooperatively developed proposals for a competitive review in 1997, provided the Initiative receives the funding requested. Anticipated funding to initiate selected proposals will be US!!news_content!!.5 million annually per project for up to 6 years. Each selected proposal has to include plans for assessing the impacts of its proposed actions, and for privatization, the third phase.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general information, publications of interests, and other information and resources related to IPM Leading Journal Marks 14th Year One of the world's pre-eminent pest management journals has enjoyed over a decade of steady growth by focusing on a broader, more integrated approach than most of the more specialized biological science journals. CROP PROTECTION (CP), published by Elsevier Science Ltd., recently marked its 14th anniversary. CP's policy especially welcomes "papers describing an interdisciplinary approach," and that demonstrate "how different control strategies can be integrated" into effective and usable pest management programs, according to the journal's aims and scope statement. CP skirts fundamental aspects of the various pest management disciplines and concentrates on practical approaches to control and management.

Four principal editors, backed by a 30-person international editorial board of experts in a variety of disciplines, produce eight issues annually. In an editorial (February 1996 issue) commemorating the beginning of the journal's 15th year, the editors signaled increased future attention to biotechnology, the impact of commercial release of transgenic plants, and studies concerned with pests developing resistance to control tools.

Like many other scientific periodicals, CP is not inexpensive, but if institutions concerned with pest management were to choose but a single journal, strong consideration would have to be given to CP.

IV. TECHNOLOGY the nuts and bolts of IPM Biocontrol Application Makes Progress Biocontrol using predators, long considered an important pest management technology either as a supplement or alone, historically has been restricted by a lack of modern methods for effectively and economically delivering the control agent to the target site. Several recent developments hold promise for overcoming this obstacle. In the U.S., a collaborative effort between a retired entomologist/biocontrol researcher, a commercial insectary, and an agricultural equipment manufacturer has produced a unique, sprayable solution and a line of specifically designed power units that together significantly increase effective application of biocontrol agents. The combination is intended to replace expensive, slow manual application methods. The solution is comprised of food-grade materials and is said to evenly and gently distribute predator species' eggs to plant foliage. The solution adheres the target surface and prevents the beneficials' eggs from falling to the ground surface, where they are rendered less effective and subject to predation, in contrast to dry carriers such as bran or rice hulls.

The powered applicators use a combination of very low pressure and forced air to gently eject the egg-carrying solution. System design intentionally eliminates the solution passing through any pressure regulator or sharp directional changes so that the beneficials are discharged relatively undamaged and enjoy a high survival rate on plant surfaces.

The self-contained sprayers, one a skid-mounted, 3-point hitch modelfor use on tractors, all-terrain vehicles, and other vehiclesand the other a backpack-style unit, permit the operator to easily control application. The spray solution is kept agitated so that predator species' eggs are evenly suspended throughout the solution. The powered units allow delivery of a specific quantity of the organisms to an area. The manufacturer notes that successful application can be made to row crops, orchards, and vineyards.

Dealing with Pheromone Dispensers To be effective, mating disruption programs to control certain key orchard pests, such as codling moth [Cydia pomonella (L.)], require correct selection, application, and placement of pheromone dispensers, according to long-term IPM research underway in the U.S. state of Washington. The number of dispensers per hectare (of apple orchard, in this case) varies with pest density or pressure, as well as the pheromone release rate which differs among the several brands that are being used commercially. Fewer units are needed for those dispensers that release pheromones faster; however, these dispensers may run out of pheromone necessitating replacement (a second application) to ensure coverage for the entire season.

Experience indicates that pheromone dispensers must be in place when the codling moth begins to fly in certain varieties of apple orchard. Since the moths usually mate the first or second night they fly, delaying dispenser application can allow an infestation to become established and force growers to take other control measures.

The Washington research team advises that proper dispenser placement is essential for effective mating disruption. Dispensers, which need to be placed in the upper one-third of the tree canopy where most codling moth activity occurs, should be securely attached to tree limbs that will not be dropped out of the upper area by fruit weight later in the season. Placing dispensers within the tree canopy, where they are also shaded by foliage, may improve their impact by limiting exposure to wind, sunlight, and high temperature.

Research for Application of Biologicals Listed The U.K. company that pioneered in the development of rotary atomizers (spinning discs) for improved delivery of pesticides, through what it termed controlled droplet application (CDA), has prepared a draft overview of research conducted on the use of CDA and low or ultra-low volume application methods for biological products. Reported work covers both aerial and surface application to manage a variety of pests, and represents a wide geographical spread. While the bulk of reports are quite recent, several noteworthy studies of more than 15 years ago are cited. In addition to an extensive reference list, the text includes sections on: B. thuringiensis; fungal entomopathogens; viruses; and mycoherbicides. The latest draft is current as of March 1996.

Crop Disease Detection Kit A highly portable, easily used "mini-lab" in a box can help detect and identify several important crop diseases. The kit makes it possible to accurately perform the equivalent of a laboratory analysis in about 10 minutes, on the premises, or in the field, according to the manufacturer. ALERT On-Site Crop Disease Detection Kits can detect and identify numerous species of Phytophthora, as well as Rhizoctonia and Phythium. A kit has been used to successfully detect disease in a variety of crops, including potatoes, soybeans, certain vegetables, and some ornamental plants. Extensive testing has confirmed the kit's ability to detect Late Blight in potatoes.

The kits are based on immunoassay methods. Each kit includes a pre-sensitized "disease detector," extraction solution, and other simple materials. Samples from the target crop are ground and treated. Color change and intensity of the detectors indicates disease presence, or absence, as well as level of the pathogen.

Use of a kit when a crop shows symptoms can help with the decision of whether or not to apply fungicide. If the test is negative, then the problem may not be caused by the tested-for disease, but due to other factors.

Kits must be kept under refrigeration until use. A detailed instruction booklet is supplied and a toll-free phone line is available. Used kits can be safely disposed of without any special requirements.
