I. IPM News

IPM: CHOICES, VISION, SUPPORT IPM has always involved informed decisions and deliberate choices. Now a recent paper by two U.S. IPM scientists casts a bright light on a second level and, perhaps, even more visionary if complex set of IPM choices.

In their article, "Approaches and Incentives to Implement Integrated Pest Manage- ment that Addresses Regional and Environmental Issues," published in Annual Review of Entomology, M.J. Brewer and P.B. Goodell point out that, from its inception half a century ago, IPM has been influenced by agricultural, environmental, and social interests with emphasis on field-based management and market-driven decision making. More recently a broader concept has arisen, with strategies such as area-wide IPM and conservation agriculture triggering a potential conflict between practices for a grower's own fields and crops, and approaches that reflect more than the immediate time frame and carry an expectation of generating wide spread environmental benefits.

The authors point to "an incentives dilemma for farmers: selecting IPM activities for individual fields on the basis of market-based economics versus selecting IPM activities best applied regionally that have longer-term benefits, including environmental benefits that accrue to the broader community as well as the farmer." In some regions publicly supported incentivessuch as financial incentives to growers to mitigate against possible decreased net income and to encourage adoption of various techniques including IPM have emerged as viable tools. Public support combined with private investment also can effectively address the incentives dilemma, particularly when IPM approaches are de- ployed regionally, Drs. Brewer and Goodell assert.

The review is designed to focus on "adaptation of IPM to these broader issues, on transition of IPM from primarily individual field-based decision-making to coordinated community decision making, and on the form of partnerships needed to gain long- lasting regional and environmental benefits." The article thus should be of interest and relevance individuals and organizations involved with IPM implementation, who are focused on identifying support through collaborating with public agencies, and possibly private sources as well.

The article appears in vol. 57, pgs 41-59, 2012 of Ann. Rev. of Entom.

IPM CENTER LAUNCHED IN THE UK Scientists at the University of Greenwich's Natural Resources Institute (UK) have launched the European Centre for IPM (EUCIPM) as an entity that will build on the Institute's long history of involvement and accomplishments in research and develop- ment of IPM technologies for agriculture in developing countries, and also in the UK.

The EUCIPM is designed to provide a platform for the Institute to contribute to both the expansion of IPM in the UK as well as to European farming. Formation of the Centre stems from both a rapid decline in available pesticides, resulting from Euro- pean Union legislation, plus the importance given to encouraging wider adoption of IPM by European growers (under the European Community [EC] 'Suitable Use Directive),' according to the EUCIPM web page.

Since that EC directive requires all farms in member states to implement IPM by the end of 2014, the Centre anticipates an opportunity to contribute to local, national, and European-wide sustainable farming through development and promotion of IPM component technologies and systems. The EUCIPM also plans to participate in the policy debate for delivery of competitive food production and ecosystem services. See: www.eucipm.org. > R.J.

THE SCOPE OF NECESSARY MINIMUM To assist growers in GERMANY reduce pesticide use over the oncoming years, two scientists have refined the theoretical concept of necessary minimum (NM) which defines a level of pesticide use above which further use is unnecessary. The term arises from the German definition of IPM as spelled out in the Plant Protection Act, 2012.

"IPM," the act states "is a combination of measureswith priority consideration of biological and biotechnical measures, resistant cultivars, cropping and cultural control measureswhere the use of chemical plant protection products is restricted to the necessary minimum."

A 2008 document states that "the necessary minimum can be described as pesticide use intensity where optimum efficacy is combined with the minimum quantity necessary. It varies depending on application parameters (pesticide selected, dosage, time, application equipment available, local conditions and using alternatively reliable non-chemical measures)."

Based on the defining statements and inputing actual field data over time and then collating data, a bell curve can be drawn with the amount of pesticide on the horizon- tal axis and number of farms on the vertical axis. The mean amount of pesticide used, with standard deviation, constitutes NM, and higher uses of pesticide above NM have potential for elimination. See: tinyurl.com > B.

III. IPM Medley > Equipment, Products, Processes, Services > Professional Opportunities > Sorting Through the "In" Box


In operations where more than one pesticide is to be applied from a mobile tank, mixing products together for simultaneous application can be beneficial by reducing trips across the land surface leading to less soil compaction, less fuel consumed by equipment, and less labor required. But there is a serious down side with potential for plant injury, damage to spraying equipment, or a resulting ineffective mix that wastes money and may negatively impact the environment.

Usually pesticide labels offer information on mixtures that may cause phytotoxicity. But labels cannot predict the effect of the multitude of possible mixtures; some combin- ations may cause physical incompatibility leading to a foamy, flaky, gelatinous or sludge-like substance that is not only ineffective on targeted pests, but leads to severe mechanical problems with equipment.

A recent issue of the informative and graphically appealing UTAH PESTS News tinyurl.com addresses the challenge of tank mixing pesticides and, as with other sites and information sources, recommends the use of the jar test to determine physical compatibility of products being considered for a tank. The follow- ing steps are based, in large part, on information in the Utah publication.

1.) A day or two before field application, establish which products are candidates for mixing. Check each product's label for compatibility profile. Determine the pH of the water source that will be used to fill the tank. Labels may state the optimal pH range for best results with their products. The pH may need to be adjusted accordingly.

2.) Add 473 ml (1 pint) of water (from the same source to be used for filling the tank) to a glass jar that has a tight fitting screw-on lid.

3.) Add each pesticide (and any other products) to the water one item at a time in the following order and amount: = water soluble pouches – 15 ml (1 tablespoon - tbs); = wettable powders – 15 ml (1 tbs); = dry flowables – 15 ml (1 tbs); = capsule suspensions – 5 ml (1 teaspoon - tsp); = emulsifiable concentrates – 5 ml (1 tsp); = soluble liquids – 5 ml (1 tsp); = soluble powders – 5 ml (1 tsp); = surfactants and other adjuvants – 5 ml (1 tsp); = fertilizers – 1.1 gm (0.039 oz). Tighten the lid and shake the jar vigorously after each addition.

4.) After all selected products have been added, shake again, let the solution stand for 1 hour, then shake again and let the solution stand another 15 minutes, then observe the results. Some authorities advise allowing the jar mixture to stand for 24 hours before being assessed for compatibility. For a compatible mixture: * Jar is cool to the touch; * mixture is smooth and homogeneous. For an incompatible mixture: * Layers form quickly after stirring; * Mixture is clumpy, grainy, foamy, or becomes sludge-like; * Jar is warm or hot to the touch.

5.) Reject use of an incompatible mixture and consider redoing the jar test with a clean jar to see if altering some steps will improve compatibility such as: * change the order of mixing; * change the water supply; * change either the brand or formulation of the product(s) to be mixed. Once a compatible mixture is determined, follow the same order of product addition when filling the tank. Rinse all utensils and jars and pour the rinse water into the spray tank. Triple rinse and discard the jar (or jars) used in the testing process.

Several free apps (for use with a smart phone) provide information on tank mixing and are available on the web. excerpted, with thanks, from the indicated website.

A recent addition to the 15 titles produced within the "Advances in Agroecology" series is said to be the first volume to "apply omic technologies to address issues related to understanding and improving agricultural sustainability in the food production pro- cess." The 2011 work, Sustainable Agriculture and New Biotechnologies, discusses a widely ranging topic selection as contributed by an international author group and edited by N. Benkeblia. The term "omics" is defined in a foreword by series editor C.A. Edwards as being a newer general term, best known to date for use in genomic, with derivation from biome, and a concept from the Greek omes (all, whole, or complete), implying "a holistic way of describing and analyzing complex biological systems." The liner notes state that "biotechnological approaches will become increasingly important in the future," but then ventures beyond that stance to suggest that "a shift from industrial to sustainable agriculture will be necessary." The hardbound, 555-page publication is proclaimed to describe "exactly how omics can contribute to greater food productivity and security" as well as agricultural sustainability. {$} -> CRC Press, 6000 Broken Sound Parkway NW, Suite 300, Boca Raton, FL 33487, USA.
