EVENT SEEKS TO STRENGTHEN MINOR CROP PROTECTION A second Global Minor Use Summit (GMUS-2), scheduled for early 2012, aims to amplify and follow up issues and obstacles cited at the 2007 event by again focusing on global matters that impact pest management for growers of crops considered 'minor' or 'specialty,' in world parlance. GMUS-2 will convened at the UN Food and Agriculture Organization's headquarters in Rome, ITALY, during 21-23 February 2012 and highlight global agreements for pesticide policy, procedure, and methodology to "help deal with minor use issues while providing growers with access to safe tools to grow their crops," according to the global minor use portal at www.gmup.org. The global summit serves as a forum for "international exchange of information on current activities" that relate to minor (pesticide) use issues, among key topics. The event will emphasize strengthened technical cooperation, discussion and international data sharing, increased involvement of all stakeholders, plus capacity building. FAO, the U.S. Dept. of Agriculture's Foreign Agricultural Service, and the U.S. Environmental Protection Agency are again jointly sponsoring the summit, with other organizations as yet to be identified. The 2007 GMUS attracted nearly 300 participants from 60 nations, and the forthcoming summit expects at least as globally wide attendance particularly engaging developing countries. A direct link to registration can be found at the GMUP website. --excerpted, with thanks, from the GMUP website and the IR-4 Project Newsletter for Summer 2011, 42(3); thanks, also, to D.

[#] PESTICIDE RISK COURSE LAUNCHED The University of Cape Town (UCT) has launched a new Post Graduate Diploma course in Pesticide Risk Management based on the United Nations Food and Agriculture Organization's UN Code of Conduct on the Distribution and Use of Pesticides, according to information on the UCT website and other sources. The course, particularly aimed at personnel in developing countries, was organized by H.-A. Rother, Health Risk Management head and principal research officer in the UCT School of


Public Health & Family Medicine, with funding from FAO and the Swedish Chemicals Agency (KemI), noted as "the driving force in the efforts to attain a non-toxic environment," per the KemI website. The initial class of 18 participants represents primarily African nations, but at least two other countries as well. The group spent the first two weeks of the course on the UCT campus before returning to their home countries to continue course work for two years via the UCT Vula on-line teaching system. Participants will eventually return to UCT for final concluding activities. The course is open to individuals with an undergraduate degree in agriculture, public health, toxicology, social science, or other relevant field. Ten modules composing the course address a variety of topics ranging from health and safety management to chemical conventions, plus issues and procedures for dealing with obsolete pesticides and pesticide container management. Dr. Rother noted that all materials developed for the course are open source and will be available to the general public in addition to course participants. Plans call for the materials to be translated into Chinese, Russian, and French versions preparatory to partnering with other universities. The next session of the course, planned for 2012-2013, is now in the enrollment process for any interested individuals. The contact is C. Lewis at Cynthia.Lewis@uct.ac.za. -> H.-A.

STUDY EVALUATES A MAJOR HERBICIDE-TOLERANT CROP To address the question of whether indirect benefits--including environmental gains--of herbicide-tolerant crops might in fact balance societal concerns related to the technology, researchers in Canada undertook a study to evaluate and quantify the beneficial impacts, if any, of a key genetically modified crop grown in Western Canada, herbicide tolerant Brassica napus (HT canola). Their findings, as reported in "Environmental Impacts from Herbicide Tolerant Canola Production in Western Canada," by S.J. Smyth, et al are illuminating. In 2007, a decade after the launch of commercial production of HT canola in three provinces of Western Canada, a survey of grower experiences revealed a reduction of 1.3 million kg of herbicide active ingredient compared to conventional usage within the canola production area. Fewer required tillage passes across HT canola fields also reduced soil compaction, improved moisture conservation, decreased soil erosion, and contributed to expanded carbon sequestration. Compared to 1995, an estimated 1 million tons of carbon is either now being sequestered, or no longer released due to HT canola production. The gain was estimated to yield a current carbon offset of C$5 million. --excerpted, with thanks, from Agric. Systems, 104(5), 403-410, June 2011. SCIENTISTS WARN OF REFUGE RISKS


An experienced group of 13 U.S. and Canadian entomologists has issued an unmistakenly stern warning that a recently approved procedure for simultaneously planting mixtures of genetically modified (GM) and conventional crop seeds could trigger several unforseen and less than desirable outcomes. The method is a newer twist on providing an in-field refuge for susceptible insects in transgenic insecticidal crop plantings. The group, headed by D.W. Onstad on the faculty of the Univ. of Illinois, concluded that a process to establish refuges in GM crops using seed mixtures, dubbed by some 'refuge-in-a-bag,' will result in making "pest monitoring more difficult." Seed mixtures also may, in the group's view, "make IRM (insect-resistance management) riskier because of larval behavior and greater adoption of insecticidal corn." In a commentary published in the Journal of Economic Entomology the group observed that planting block refuges, an earlier technique used for some time and condoned by at least one major commodity group, is also not without serious risks. The primary problems of this practice, in the group's view, are adult pest behavior, and the failure of some growers to comply with currently promulgated IRM rules specifying size and location of block refuges. "It is likely," the group's commentary noted, "that both secondary pests not targeted by the insecticidal corn as well as natural predatory species will respond in differing fashion to block refuges compared with cropped areas based on planting seed mixtures." -> D.W.

NEW EDITION OF IPM GUIDE FOR HOPS One doesn't need to like beer to fully appreciate a highly informative and artfully executed 2010 volume devoted to IPM for Humulus lupulus (hops). Overflowing with clear, crisp full color photos throughout, a Field Guide for Integrated Pest Management in Hops, second edition, not only addresses identification and management tactics for the main groups of commonly encountered pests in H. lupulus, it does so in a straight forward manner accompanied by useful tables and charts. The 89-page work uses "at-a-glance" side bars to further enhance its utility. Editor-contributors D.H. Gent, et al, provide expert information for effectively managing pest organisms in hops, a unique crop with a unique set of challenges. A balanced approach includes both biocontrol information as well as data for conventional practices. Adding to the publication's aura is the delightful layout devised by S. O'Neal that incorporates use of


heavyweight coated paperstock that makes the color photos pop and use of a lay-flat spiral binding for in-field convenience. The title is a cooperative publication produced by Oregon State Univ., Univ. of Idaho, the U.S. Department of Agriculture's Agricultural Research Service, and Washington State Univ. The Guide can be freely downloaded from http://tinyurl.com/3tvknv4. Hard copies, from a limited supply, may be requested from: Washington Hop Commission, PO Box 1207, Moxee, WA 98936, USA. [#] EXTENSIVE NEW REFERENCE ON MITES The goal of a new and extensive reference volume, Agricultural Acarology, is, according to its preface, to "provide pest-control workers and students with the tools to manage mite pests of agriculture using the concepts of integrated pest management (IPM), so mite management becomes an integrated effort rather than one based largely on chemical control." Hence the 2011, hardcover publication's subtitle, "Introduction to Integrated Mite Management." Author/ entomologist M.A. Hoy has achieved the stated goal with 430 pages of coherent, highly applicable text and data backed by numerous black/white illustrations, all of which are influenced by both her long acarological experience and her firm belief in the value and application of IPM approaches. The work's 25 chapters leave very little about mites unexplained, ranging from identification basics to the nuances of understanding the roles, nature, and impacts of mites broadly and most specifically in agricultural settings. The book comes with a companion CD that contains full color supplementary photos for each chapter. The title is also available as an e-book. -> CRC Press, 6000 Broken Sound Parkway NW, Suite 300, Boca Raton, FL 33487, USA. See: http://tinyurl.com/3brq2ka. [#] IPM SCOUTING MANUAL FOR FIELD CROPS (AND MORE) An extensive amalgam of key information has been melded into the Crop Scouting Manual, 2010, prepared by IPM specialists and others at the Univ. of Wisconsin, USA. Text and visual (a large percentage in full color) data in the Manual is designed to help field staff conduct intelligent and accurate assessments of pest insects, weeds, and diseases--the fundamental backbone of designing an effective IPM approach. At over 300 pages, the publication represents an invaluable asset for field personnel charged with scouting responsibilities. While the primary focus is on field crops and conditions prevalent in Wisconsin, the presented information has far broader utility and potential for extrapolation.

VI. U.S. AID's IPM-Collaborative Research Support Program (IPM-CRSP) - International Workshop Focuses on Biocontrol - Philippines: Impact of Field Schools INTERNATIONAL WORKSHOP FOCUSES ON BIOCONTROL An international workshop on production of biocontrol agents was convened during July 2011 at Tamil Nadu Agric. Univ. (TNAU), Coimbatore, INDIA, focused on review of current research on the selection, development, mass production, mode of action, and use of biocontrol agents in agriculture, specifically Trichoderma and Pseudomonas. The workshop included participants from six Asian countries and was sponsored by the IPM-CRSP program. Attendees discussed activities involving use of Trichoderma and Pseudomonas as components


of IPM programs. Recent information for using microbial agents to help control plant diseases was presented via lectures and laboratory sessions. Additional information focused on induced system resistance (ISR) and system acquired resistance (SAR), storage and shelf life of biocontrol agents, quality control and registration, as well as the role of gender in the production and utilization of biocontrol agents in IPM. The group also took field trips to research plots, to a private firm developing and commercializing microbial biocontrol agents, and to the Biocontrol Research Laboratories (BCRL) in Bengaluru, Karnataka, to learn about the range of activities BCRL scientists undertake, especially related to Trichoderma, Pseudomonas, insect pheromone traps, and other pest management agents.
