IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news, and application of IPM techniques and programs Caribbean Workshops Urge IPM Adoption Participants at two Caribbean technical workshops concerned with crop protection formulated and endorsed a series of recommendations calling on area governments to adopt a series of IPM policies. Representatives from 12 nations in the Caribbean region attending the first workshop, and 14 at the second, called on regional governments to "explicitly adopt IPM as national policy for sustainable agricultural development." Among additional points the delegates urged were that:

IPM be developed as a commodity approach; training be implemented in integrated procedures; current IPM practices be inventoried and made available; IPM information, including profiles of key pests in the region, be developed as databases; and that, the "farmer participatory training" approach successfully developed and implemented in Asia be incorporated into any IPM program. The two workshops, organized and conducted by FAO in conjunction with local governments, took place in October 1994 and were primarily focused on vegetable production and weed management respectively.

IPM Means Profits to Pecan Growers IPM helped growers in the U.S. state of Texas significantly raise yields of pecans (Carya illinoensis Koch) while increasing profits and reducing insecticides by 27 percent. The pecan, one of the most important native horticultural crops in the U.S., grows throughout the southern tier of U.S. states and is attacked by a complex of insects and diseases. Data from 1991 recorded that well over half the growers in Texas used regular insecticide and fungicide applications.

Texas A&M Univ. IPM scientists conducted 24 IPM workshops in six locations during a 2-year period to help producers with management of pecan pests. Participants, representing approximately 23 percent of the state's commercial pecan producers, were provided information about using computer prediction models, sampling for both pests and beneficial insects, and determining levels of pests present. They also learned which pesticides were least disruptive to natural enemies of insect pests.

According to a 1994 survey conducted after the workshop series, 63 percent of the attendees adopted an IPM approach and used insecticides only when pest insect populations exceeded threshold levels.

Managing Pests in Mongolia In Mongolia, "There is tremendous potential to increase the productivity of cereals and potato by inducing technological changes in weed management strategy in these crops," according to a report published by the Asia and the Pacific Working Group for Improved Weed Management. In particular, farmers in Mongolia's extensive dryland areas have been slow to accept weed management techniques, reports R.K. Malik (India), even though they have "achieved a moderate breakthrough in increasing their productivity through new cultivars and a little fertilizer," he noted. The planning process in weed science has reached a point where new approaches and strategies are needed.

Heavy infestations of Brandt's voles and limited means for rodent damage control have caused severe depletion of Mongolia's vast grassland resources, reports D.L. Nolte, a specialist with the U.S. Dept. of Agriculture's Denver Wildlife Research Center, (DWRC) who assessed rodent problems during an FAO-sponsored visit.

As outcomes, DWRC will present a short course on vertebrate pest management in Mongolia and will assist Mongolian scientists with demonstration trials. FAO also plans to establish, with DWRC's assistance, a pest management laboratory in Mongolia, at Ulan Batar, and plans to help the country initiate a research program to improve the methods available for managing rodent caused damage to rangelands.

IPM Buoys Cranberry Producers IPM and use of organic fertilizers that are less likely to leach are helping cranberry producers in the U.S. state of Michigan reduce input costs and realize cost savings. In a four year study funded by Agriculture in Concert with the Environment (ACE), producers at five commercial cranberry bogs reduced herbicides and insecticides by more than half, fungicides by 44 percent (with two-thirds of the applications using more environmentally friendly copper-based compounds), and nitrogen fertilizer by 47 percent.

An improved water management strategy, intensive pest scouting, use of microbial insecticides, and other measures helped reduce crop damage from cranberry fruitworm (Acrobasis vaccinii Riley), cutworms, mites, and fruit rot, according to the ACE study.

The cooperative research involved growers, researchers, processors, and the U.S. Environmental Protection Agency. Results indicated that, depending on the interaction of weather and the water management practice, crop yields can decline by up to 10 percent in certain years. However, sustainable techniques can maintain overall profits through cost reductions and yield increases in other years.

IPM MEDLEY --- publications and other IPM information resources

II. FORUM / EDITORIAL viewpoints, opinions, and discussion of IPM issues. IPM and the Importance of Record Keeping A Viewpoint Pest managers, to make correct decisions, need good information about the status of pests and crops. However, simply increasing the volume and precision of information does not necessarily help managers make the correct decision. Collecting unnecessary information can bog down the system by increasing costs and the time it takes to make a decision. Information needs to be timely and directly linked to the management objectives of the cropping system. Sequential sampling plans that link pest, natural enemy, and crop phenology to decision making can facilitate the adoption of IPM in a cropping system. Although this approach has been successful for a variety of agronomic crops, it is unlikely to be used in the near future for ornamental crops; there are simply too many kinds of ornamental plants, pests, and management situations to allow development of individual sequential management schemes. Furthermore, the complexity of the ornamental system can make it difficult for pest managers to record and summarize scouting information.

Three tools have been developed that can improve information gathering and record keeping for ornamental crops. The first is a conceptual model for determining management objectives for an ornamental system. Although ornamental plants are valued for their appearance, individuals who produce plants have different objectives from those who manage them in the landscape. Ornamental crop producers are similar to agronomic producers in that they seek to optimize the balance between production costs and sales of plants. In contrast, landscape managers need to keep clients satisfied with plant appearance. In general most people are dissatisfied with a plant's appearance when 5-10 percent of its leaves are distorted, disfigured, or discolored. Recognizing differences between management objectives can help managers make decisions that are appropriate to their management situation.

The second tool is the more widespread use of degree days and phenological indicators to link scouting events to pest activity. Data pods that track accumulation of heat units have been widely used to help derive relationships between pest biology and weather conditions. For instance, in linkages made between the bloom time of common landscape plants and pest activity have been verified in several U.S. regions of the country.

Finally, computers are becoming available to help pest managers record and summarize scouting information in an organized manner. At Purdue Univ. (USA), software is being developed for nursery and landscape pest management that allows scouts to rapidly assess plant appearance, pest density, and the proportion of the crop at risk. Currently software for landscapers is available with a 90 page manual designed to guide individuals in the field and at the computer. A companion version for nurseries will be released in the next six months.

Pest Management, Precision Agriculture, and Technology Advanced technology is being applied across society. A research scientist offers a thoughtful view of how it may impact pest management in relation to the practice of "precision agriculture." Ed. GIS (Geographic Information System) software and GPS (Global Positioning System) hardware are being used to develop and apply a wide range of new technologies to agriculture in the area of precision agriculture, including pest management.

In precision agriculture, inputs are applied to fields when, where, and in amounts needed. If chemicals are used, minimizing amounts and areas of application is particularly advantageous because this will minimize the environmental impact of the chemical. If biological control agents are used, precise application will minimize the cost of inputs.

GPS/GIS and variable rate application hardware is being offered by a number of agricultural equipment companies to apply many ag inputs in precise quantities to narrowly defined locations according to field maps. The problem lies in developing the maps that will identify exactly where the inputs are needed. For water and nutrients, maps can be based largely on soil samples and yield maps (yield monitoring equipment). Draft or torque sensors on tractors can give information about changes in soil texture to the depth being tilled.

For pests, the problem is more difficult. Topology maps (exact elevation of key species in a field) can offer valuable information about where problems are likely to occur. Soil borne pests tend to reappear in the same locations and spread out from there if not controlled. Thus, field surveys with a GPS can be used to precisely identify problem areas when the pests are visible. This is feasible for nematodes and wireworm for example.

If the pests affect the plant appearance in an area of at least 3 meters diameter, aircraft borne remote sensing equipment may be used to map problem areas. Viruses carried by aphids into potato are a good example. Research at the Univ. of Califorina, Davis, aims at identifying root louse infested areas in grapes with imagery taken from aircraft.

Tractor-mounted sensors that can identify shapes of weed leaves are also being developed. If the sensor identifies a weed, a squirt of herbicide could be applied to the exact spot as the sprayer behind the tractor passes over. The amount of chemical applied to a field would be a tiny fraction of that used in conventional spray treatments, and herbicides otherwise damaging to the crop could be considered, broadening the farmer's choices.

The next few years should see rapid changes in availability and costs of these technologies. Comments by farmers on what pests might be controlled by these technologies will be valuable to researchers and engineers developing new equipment.

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

III. RESEARCH ROUNDUP research and findings related to IPM. Transgenic Biocontrol Needs Risk Assessment Molecular methods for genetically manipulating arthropods create opportunities for altering genomes of pest and beneficial organisms alike. However, these advanced techniques also impose significant new responsibilities and hurdles for both research and regulation, contends research entomologist M.A. Hoy. In her paper, "Impact of Risk Analyses on Pest-management Programs Employing Transgenic Arthropods," Dr. Hoy observes that "deploying a transgenic arthropod in a pest management program will be an awesome challenge, requiring risk assessments, knowledge of the population genetics, [and] biology and behavior of the target species under field conditions."

Because of the potential risks, Hoy contends that releasing a relatively risk-free example initially may be the preferred course of action. Once the risk assessment issues of releasing a beneficial arthropod are evaluated, releases of transgenic pest arthropods might be more readily assessed. Both procedures continue to increase in terms of required time and the consequent costs.

Hoy also cites the need for, and importance of, "coordinated efforts between molecular and population geneticists, ecologists, regulatory agencies, and pest management specialists."

V. IPM MEDLEY general information, publications of interests, and other information and resources related to IPM Biocontrol Promising for Widespread Weed Bugweed, Solanum mauritianum, is widespread, particularly in forestry, in the Natal and Transvaal areas of South Africa. Although susceptible to herbicides, the extent of infested area makes herbicide use financially prohibitive, according to T. Olckers, a scientists in the Weed Research Division at Cedara. Following a 1994 trip to South America to collect potential biocontrol agents, several species were imported, successfully cultured, and placed in quarantine. Special attention focused on six defoliating chryssomelid beetles. Initial results indicate that all six species are restricted to the Solanum genus, and further tests are continuing.

Wildlife Center Report The Denver Wildlife Research Center (DWRC) has published an extensive HIGHLIGHTS REPORT, FISCAL YEAR 1994, describing a wide range of research, outreach, and other activities conducted by the Center and its field stations. One of the year's highlights was the symposium on contraception in wildlife management, co-sponsored by the Center and three other organizations, and attended by 200 representatives from eight countries. Presented papers covered numerous aspects of the theme.

DWRC has a new name, National Wildlife Research Center (NWRC), coincident with its relocation from Denver to new, stateof-the-art facilities on the campus of Colorado State Univ. at Fort Collins, CO. NWRC remains a part of the U.S. Department of Agriculture's Animal and Plant Health Inspection Service.

The report is miscellaneous publication no. 1530, illus., 34 pgs, published in July 1995. For further information, contact: Office of Communications, USDA, Washington, DC 20250, USA.

Caribbean IPM Workshops FAO has published two summary reports for technical IPM-related workshops held in the Caribbean in late 1994. They are: INTEGRATED PRODUCTION AND PEST MANAGEMENT PRACTICES FOR VEGETABLES; and, INTEGRATED WEED MANAGEMENT IN THE CARIBBEAN. Both reports (identified as CULT-43, and PROVEG-34, respectively) summarize the various technical presentations and conclude with a list of recommendations. The first workshop was based on the fact that vegetable production in numerous Caribbean states depends heavily on pesticides which has led to pest resistance and other problems. The event was organized to consider the issues and propose new strategies for producers.

Copies of both documents can be obtained from: Plant Production and Protection Division, Attn: R. Labrada Romero, FAO, Via delle Terme di Caracalla, 00100 Rome, ITALY. Fax: 39-6-5225-6347. Phone: 39-6-5225-4079.

MATERIALS & EQUIPMENT INSECT REPELLENT A U.S. firm produces a non-synthethic product registered as an insect repellent for crops both plants and trees. Guardian Spray is described as a biochemical pesticide generally, and specifically designated as an insect repellent and/or feeding depressant. It does not kill organisms. The product is manufactured from garlic (Alium sativum) utilizing a patent pending process. An enzymatic base is the active ingredient. The manufacturers have conducted extensive testing and, though unsure of the mode of action, suspect resulting improved plant nutrition combined with minute quantities of dimethyl sulfoxide and selenium provide the repellent effect.
