IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs IPM Adoption: Willingness and Confusion A recent survey of growers in the U.S. state of New Jersey revealed a willingness to adopt IPM tactics, but also showed that there remains significant confusion about which farming practices actually constitute "IPM," and confirmed a nagging perceived communication-education gap between growers and various sources of IPM information. In the article, ඓ% Adoption of Integrated Pest Management by 2000? A Case Study from New Jersey," (in AMERICAN ENTOMOLOGIST), G.C. Hamilton and colleagues report their findings. A 33-question survey, complete with definition of IPM and designed to divulge why growers did or did not participate in IPM programs, was sent to 270 growers of various crops. Only 52 forms were completed and returned, but upon analysis the results offered several clear trends.

Both those growers claiming to follow IPM practices and those who said they did not pointed to regulations, crop values, and labor costs as primary obstacles to continuing to farm, but not necessarily related to practicing IPM. The investigating team of scientists and extensionists found that marketing played a key role in IPM adoption. Changing the way they market their crops showed promise as an avenue to help non-IPM growers increase use of IPM tactics.

All growers in the survey indicated that greater access to state, university, and privately sponsored IPM programs (information, counsel, demonstrations) would help accelerate IPM adoption. However, perceptions of useful information sources differed between growers, and county extension agents and chemical industry representatives who were also queried. The latter group placed more emphasis on neighbors as a source of information for growers than did the growers themselves.

Blunting Resistance to Herbicides The increasing emergence of herbicide-resistant weed species prompted research and extension specialists to develop guidelines for growers to use to minimize the possibility of inadvertently helping to spread resistant species. This approach is based, in part, on how various herbicides work, i.e., their sites of action within the plants they contact. Recently, E.J. Retzinger, Jr., and C. Mallory-Smith published "Classification of Herbicides by Site of Action for Weed Resistance Management Strategies," listing the characteristics for numerous herbicidal products. According to the authors, the listing was "developed to help maintain the usefulness of herbicides as a tool in crop production" and to also slow the emergence of herbicide-resistant weeds.

In their paper, the authors refer to a set of guidelines published by the Weed Science Society of America (WSSA) for promoting awareness of the problem and recommending steps that growers should follow. The following points are broadly based on the WSSA guidelines.

Scout fields (I): before applying a herbicide; determine weed species present. Evaluate economics: is herbicide application justified by increased returns? Consider use of alternatives: cultivation, delayed planting, using weed-free crop seeds. Rotate crops: avoid growing the same crop in the same location season after season. Limit herbicide application: minimize usage of a single herbicide, or herbicides with the same site of action, during a growing season. Vary herbicides: use mixtures or sequential applications. Scout fields (II): after applying herbicides, note weed escapes or species shifts. Eliminate weed seed transfer: clean off equipment and clothing before moving from an infested area. excerpted from: WEED TECHNOLOGY, 11(2), 384-393, April-June 1997.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general information, publications of interest, and other resources related to IPM Sorghum Ergot Appears in North America Almost prophetically the INTERNATIONAL SORGHUM AND MILLETS NEWSLETTER recently published the feature article, "Ergot - A Global Threat to Sorghum," recounting the disease's worldwide spread, but noting that, as yet, it had not been reported in the USA. It has now. In March 1997 Scientists from Texas A&M Univ. confirmed presence of the dreaded disease in south Texas. Ergot (Claviceps spp.) is a fungal disease that infects the floral parts of the sorghum plant [Sorghum bicolor (L.) Moench] that would normally develop into seeds. Instead of seeds, infected plants produce a sticky fluid which can spill onto other seeds complicating harvest and encouraging growth of saprophytic fungi that blacken the head.

Depending on temperature and moisture, a chain reaction can develop favoring production of secondary conidia that are easily wind-borne to nearby areas. Spread can be devastatingly rapid, as evidenced by epidemics in Brazil (1995) and Australia (1996).

The Sorghum Improvement Conference of North America (SICNA) and the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) have produced a clear, full-color leaflet as part of the article mentioned above. Close up photos and descriptive text profile ergot and its nasty effects on sorghum.

Options for ergot control involve: enforcing quarantines; planting seed produced in ergot-free areas; altering planting dates to allow flowering when weather conditions are unsuitable for disease development; removing collateral hosts and rogueing infected plants; and, protecting seed production plots with a suitable fungicide.

IPMporium .... According to a recent issue of AREAWIDE IPM UPDATE, "most consultants see more consistent biological control of aphids where the use of broad-spectrum insecticides has been reduced or eliminated, as in orchards using codling moth mating disruption." quoted from AREAWIDE IPM UPDATE, 2(8), 3, July 1, 1997. .... Two years of field trials have shown that reduced usage of herbicide on row-grown processing tomatoes in Northern California provided sufficient weed management in all but the weediest areas, and did not lower crop yields.

.... A U.S. firm has indicated its intent to conduct small-scale field testing of a microbial pesticide involving a microorganism which has been genetically engineered to: (1) express an insect-specific pesticidal toxin from the scorpion Androctonus australis; and, (2) prevent expression of the ecdysteroid gene. The tests are aimed at control of the tobacco budworm (Helicoverpa virescens Fabricius) and the cotton bollworm (H. zea).

PESTICIDE USE REDUCTION POLICIES Pesticide Action NetworkAsia and the Pacific, one of the regional centers for promoting alternatives to pesticides, has commissioned and published a useful literature review, REDUCING RELIANCE: A REVIEW OF PESTICIDE REDUCTION INITIATIVES. The extensively documented, 93-page monograph surveys numerous national pesticide policies, especially those advocating reduced usage of pesticides. The softbound work provides a framework for workable pesticide use reduction initiatives. Authors M. Watts and R. Macfarlane are less clear about the definition, role, and benefits of IPM in achieving lowered pesticide levels. The 1997 publication performs its intended service: summarizing a vast body of information in a single document.
