Learning Groups Benefit Growers

An impact survey conducted in 2002-03 by the joint Egyptian-German program to extend IPM to Egyptian fruit and vegetable farmers found that exposure to Farmer Learning Groups (FLG), a participatory extension approach modeled on the FAO's Farmer Field Schools, resulted in improved skills and knowledge for farmers, according to a new report.

The program, supported by the German Agency for Technical Assistance (GTZ), surveyed both physical and financial indicators as well as adoption rates of recommended IPM and cropping management practices. Farmers who had participated in FLGs were 45 percent more likely to implement IPM elements than those who had not come into contact with an FLG. A middle group, farmers living in the same village as those attending the FLG and benefitting from a "spill-over" effect, also practiced a higher degree of IPM than those without any contact.

The FLG-participating farmer group realized improved production rates, higher quality crops, and a 21 percent greater income level than farmers without any extension contact. Again, the farmers in the spillover category improved in comparison to the base group. Additionally, cost-benefit analyses prepared for the IPM project were clearly positive, particularly so when the "spill-over" affect was included. *> W.

High Tech Weeder Shows Promise

A prototype video-guided, GPS-enhanced, herbicide-applying machine is under study in California as a way to increase the efficiency of chemical application and reduce the need for hand weeding in crops such as processing tomatoes, lettuce, and cotton that currently require intensive hand weeding or hand hoeing.

While numerous improved spraying devices have been developed in the past by various entities, the device under test at the Univ. of California at Davis is believed to be the first to utilize video technology, mathematical computations, and micro-spray needles combined and mounted on a field-tested robotic cultivator.

Increasing pressure from farm worker advocates to limit hand weeding and short-handle hoeing as being damaging to workers' backs is forcing U.S. growers to seek alternatives. But herbicide application, particularly to food crops, needs to be extremely precise to avoid problems.

Enter the prototype device conceived and constructed to apply only the precisely required amount of herbicide and to do so with pinpoint accuracy and without overspray or waste.

The goals are to achieve effective weed management and eliminate major physical harm to farm workers, as well as decrease both herbicide usage and potential for any chemical residues on the crop.*> W.T. Lanini, Lanini@vegmail.ucdavis.edu .

While rodents as a key group account for more than 40 percent of known mammalian species, only an estimated 5 percent of rodent species are pests, but as such are capable of causing severe losses of crops in many world regions, as well as being reservoirs of organisms that cause debilitating diseases in humans and livestock. An extensive 2003 document, RATS, MICE AND PEOPLE: RODENT BIOLOGY AND MANAGEMENT, focuses on important aspects of rodent-human interactions and offers dozens of papers and reports, many arising from the 2nd International Conference on Rodent Biology and Management in early 2003. Editors G.R. Singleton, et al grouped materials into nine "symposia" ranging from taxonomy and behavior to management, both in the field and in urban settings. The softbound, 564-page work is functionally organized and attractively presented. While emphasizing Asian experiencethe Australian Centre for International Agricultural Research (ACIAR) sponsored the publication, which is ACIAR Monograph #96the presented information is comprehensive and broadly applicable. *> Communications, ACIAR, GPO Box 1571, Canberra, ACT 2601, AUSTRALIA.

Roughly every decade, the global sorghum and millet pathology community meets to assess progress, doing so most recently in 2000. Most of the numerous papers presented at this conference have been melded into a 2002 volume, SORGHUM AND MILLETS DISEASES, containing the decennial summary of work in progress as well as setting forth the critical areas for future research. Editor J.F. Leslie has not only included conference presentations, but has expanded the book's coverage beyond to round out this 516-page, landmark reference. The hardbound work offers dozens of papers by global experts compiled into 21 chapters, and stands as "a considered summary" of current critical problems in disease management for these globally important crops. *> Blackwell/Iowa State Press, 2121 State Ave., Ames, IA 50014-8300, USA.

Herbicide resistant weeds are a growing problem (and a very tiredpun) that is drawing increasing attention. A recent 4-page publication (no. A3615) from the Nutrient and Pest Management program at the Univ. of Wisconsin (USA), "Avoiding Herbicide Resistance in Weeds," by R. Proost, et al colorfully describes the issue, asks key questions, and most importantly sets forth succinct information about various herbicidal modes of action, plus key steps to help forestall resistance development.

A comprehensive new (2003) report assesses the relationship between modern agricultural production and the loss of valuable biodiversity, and then examines the potential of biotechnology in the form of genetically modified crops to slow down or even reverse the bio-slide. In "Biodiversity and Agricultural Biotechnology, A Review of the Impact of Agricultural Biotechnology on Biodiversity," on-line at www.bio author K. Ammann asserts that, "by slowing the rate at which natural habitats are destroyed, GM crops and other technologies that increase agricultural productivity can help to preserve natural biodiversity." He contends that "GM crops are important tools in the preservation of biodiversity," and "creating agricultural systems with minimal impact on biodiversity will require utilizing all available technologies while simultaneously encouraging appropriate farmer practices."*> K.

Material from INVASIVE PLANTS OF CALIFORNIA'S WILDLANDS edited by C.C. Bossard, et al originally published in 2000 through the California Exotic Pest Plant Council (CalEPPC) as a 360-page volume (133 color photos, 76 black/white illustrations), can now be found in an on-line version at: groups.ucanr.org A database provides nomenclature, description, management data, and more for dozens of plant species.



An insect cage specifically designed to study insect-plant interactions (based on actual whitefly research) offers improved convenience as well as greater consistency and reliability due, in part, to reduced pathogen presence, according to the maker. Known as the Polaris Insectary, the 12kg (26.5Lb) device separates the insect chamber and watering medium, thus avoiding fungal growth in the former and algal presence in the dark watering system. Clear acrylic panels on four sides can be removed for cleaning or replacement, and two have quick releases to allow large plants to be inserted or removed. Two smaller doors on the 56x60x60cm (22x23.6x23.6in.) insectary have handles and are attached with magnetic strips. Apertures are covered with 50 mic. mesh, and a circulating fan moves air through the cage to eliminate condensation. A water level sensor warns of low water levels. Units pack flat for shipment. *> Polaris Instruments, 1 Home Farm Court, Diddington, St. Neots, Cambridgeshire PE19 5XT, UK. Fax: 44-0-1480-811311. Eml: information@polaris.co.uk .

Profiles and Strategic Plans

Outcome from a law passed in the U.S. several years ago includes extensive review of pesticide use data for both major and minor crops. Because some of these uses will no longer be legal, the need for a thorough review of the current situation and future requirements became urgent. A fundamental tool for gathering all the information needed to conduct assessments is the crop profile (CP), an omnibus document that not only describes the crop, but includes pest management issues and other information bearing on the crop's production.

Crop profiles assume a variety of formats, reflecting the individual approaches and concerns of each state (region) all of which are under directive to prepare them, but basically are designed to: Fully describe production practices; List problem-causing pest organisms; List main pest management practices (and specifically pesticides currently in use, if any); Identify critical pest management needs, current and future; and, List farm worker operations during the crop cycle. Formats allow for text and visual illustrations as well as tables and charts. Content in any form is aimed at providing the information that fully profiles a specific crop in a specific state or locale.

A second set of documents, Pest Management Strategic Plans (PMSP), build on CPs and are developed through collaborative efforts of growers, commodity organization, research specialists, food processors, crop consultants, and governmental officials. PMSPs are oriented toward a pest-by-pest approach that identifies current management practices and materials, and those under development. PMSPs are also designed to state a commodity's priorities for research, regulatory activity, and education/training programs needed for transition to alternative pest management practices.

Completed CPs and PMSPs are all listed on the U.S. Dept. of Agriculture Regional Pest Management Centers website at: www.pmcenters.org ; crops for each of the four national regions are also listed on that regional center's specific website.
