7. 20th MOP - Doha Critical Use Nomination Overview

8. Trends in Total Amount (mt) of MB Approved or Nominated for Critical Uses from 2005 - 2010 Total amounts approved for critical uses continue to fall in all countries, but at different rates.

9. MB Amounts Approved or Recommended for Approval by Parties for Continuing Nominations (2005 to 2010) NZ, Switzerland and the EC have ceased submitting CUNs.

10. 2008 Nominations and Recommendations by Party (metric tonnes) MBTOC recommended amounts under consideration for the 2008 round are shown in brackets. * Renominated amount.

11. Progress in MB Phase out by Sector • In the 2008 round, MBTOC considered nominations for 4740 t MB for soils uses and 321 t MB for post harvest uses requested for either 2009 and 2010. Amounts in 2010 were revised downwards by 602 t. • 95% of the reduction of MB for controlled uses in non A5 countries is for phase out for preplant soil uses. MB Consumption (tonnes)

15. MB Preplant Soil Use - 2008 CUN Round • 31 CUNs submitted, 12 for 2009 and 19 for 2010. • 10 nominations were reassessed based on new information from the parties after the OEWG-28. • The US revised their total nominated amount from 3722.23 t to 3164.982 t to account for uptake of iodomethane which obtained a new registration in Florida and reregistration in all States except California. (Revised nominations were received for tomatoes, strawberries, ornamentals and peppers). • Japan submitted new technical advice on its action plan to phase out by 2013, and this led to reassessment of four CUNs (cucumbers, peppers, melons, watermelons).

16. Changes in nominated and recommended amounts of MB for preplant soil uses after the interim report (May 2008) * Japan sectors reconsidered - cucumber, peppers, melons & watermelons

17. Final recommendations for soil use in 2009 and 2010(metric tonnes)

18. Progress in phase out of MB for major preplant uses - Vegetable crops • The US (5), Israel (4) and Japan (4) are the remaining nominating parties. Other parties have phased out MB for vegetable crop uses.

19. Progress in phase out of MB for major preplant uses - Strawberry fruit crops • US and Israel are the remaining nominating parties. Australia, EC (France, Spain, Italy, United Kingdom) and New Zealand have phased out MB for this use.

21. At the request of the United States at the OEWG-28, MBTOC considered the economic feasibility of IM in a partial budgeting analysis framework. For many crops and locations, IM is an economically feasible alternative. The cost for fumigant is typically a relatively small share of total costs and variable production costs. After adjusting for dose rates expected to provide equivalent yields, IM/MB price ratios of 1.4 to 2.0, result in percentage changes in net revenue which can be very small (<2%) for high value cash crops (>US$50,000/ha). Economic feasibility of Iodomethane (IM)

22. Issues raised by the CUN08 for preplant soil CUNs • In early 2008, registration of iodomethane was obtained in 45 US States, and a non timebound reregistration granted. The US reduced the nominations by 558 t to account for this progress. Registration of IM is expected in Australia, Israel & Japan. • A number of other chemicals are now in the registration process for specific sectors, including dimethyl disulphide (DMDS) in Europe and the USA and ethane dinitrile (EDN) in Australia and a range of new herbicides.

23. CUN Preplant Soil Uses - Significant Issues • Australia and Canada could reduce CUNs if they adopt regulatory changes that lower MB dose rates and/or adopt barrier films for strawberry runners. • Japan has further developed an action plan with alternatives identified to achieve phase out for all preplant soil uses by 2013. • Israel is considering registration of chloropicrin and 1,3-D/Pic to reduce MB use. • Israel, Japan and SE USA continue to increase use of barrier films to reduce MB dose rates, however they are still prohibited in California.

24. MOP-20 Doha, Qatar MBTOC QSCQuarantine, Structures and Commodities

25. EU publication of Maximum Residue Limits (MRLs) for fluoride resulting from SF treatment of dried fruit and nut commodities resulted in ~ 55% reduction in US commodities the 2010 CUN because their main export market is the EU. Development of alternatives for high moisture dates is being conducted under aegis of UNIDO. New information from the US indicates the dates in their CUN are also high moisture fresh dates. Applicants with CUNs continue to support research efforts on alternatives in commercial scale trials and adaptations and to make necessary contributions to registration efforts.

26. 2008 CUNs for 2009 and 2010

27. Australia rice 2010; nominated 7.82 tonnes. Recommended 6.65 tonnes. Australia reported rice growers beleaguered by drought will not adopted alternatives until rice harvest revert to pre-drought levels. Canada flour mills 2010, nominated 22.878. Recommended. Canada requested less MB than is required for one MB fumigation per year per mill. A new regulatory change allows sharing of MB allocation, within the sector, to the neediest mills. Canada pasta 2009; reduced nomination of 4.74 was recommended. This allows partial treatment of three pasta mills. Canada’s currently has a zero MRL for fluoride residue from SF treatment of flour mills or pasta facilities. This makes the use of SF difficult or impossible under some circumstances. Israel dates; nominated 2.1 tonnes. Recommended. Doing research to try to expand heat treatment to other varieties QSC CUN Summary

28. Israel flour mills, 2009; nominated 0.3 tonnes. Recommended. Industry may replace MB with spot heat treatments by 2010. Japan chestnuts, 2010; nominated 5.4 tonnes. Recommended. Methyl iodide suitable but not yet registered. US commodities 2010; reduced nomination from 43.007 tonnes to 19.242 tonnes. Recommended. We hope a new understanding of its date sector will enable the US to expand date research. US food processing facilities 2010; nominated 37.778. Recommended. CUN indicates 2010 as final year for transition in herbs and spice equipment and processed food facilities, except cheese in storage. US mills and processors 2010; nominated 191.993. Recommended 173.023. Reflects significant decreases in rice milling and pet food processing approx 24% decrease in flour milling. US dry cured pork 2010; nominated 4.65. Recommended. There is no technically effective and registered alternative for this use. QSC CUN Summary cont’d

29. CUE/CUNs for 2009 and 2010 assessed in 2008 round (metric tonnes) • Total • Initial nominations 321.808 • Revised nominations 277.746 • Additional quantity nominated for 2009* 7.14 • Additional quantity recommended for 2009 7.14 • Quantity nominated for 2010 270.606 • MBTOC recommendation for 2010 269.436 • *Not including first round of CUNs in 2007 for 2009

30. MBTOC’s review of the current status of flour milling alternatives was published in May TEAP report. Flour milling is the largest non QPS post harvest MB use in CUNs from Canada, Israel and the United States. MB nominations have declined each year, but slowly. Some flour mill representatives express continuing concern about the efficacy and cost of alternatives. Fumigators with experience in alternatives say they work and costs are reasonable. MBTOC’s report summarizes methods to ensure flour mill pests -- at all life stages -- are controlled with MB alternatives Current Status of Technical Efficacy, Costs and Adoption of Methyl Bromide Alternatives in Flour Mills

31. There are consistent indications of the ineffectiveness of SF in killing insect eggs at low or ambient temperatures, Unlike MB, current regulations do not allow SF to contact many food ingredients present in mills. These factors sometimes discourage the adoption of SF. As with MB, which also does not always kill all insect life stages present, other pest management methods could be deployed to keep the mill pest free. Insect eggs can be killed by increasing SF dosage rates, but adds cost and might not be the wisest choice from a total environmental perspective. Key Technical Concern

32. Intensive sanitation and enhanced integrated pest management (IPM) are prerequisites to full site treatment. Heat treatments – 50°C for 24-36 hours - are effective when carefully planned and executed with additional pest barriers. SF fumigations should be conducted jointly with heat to a temperature of 27°C (80°F) to achieve satisfactory egg kill. In many cases, supplemental heat will be required. The majority of pest control operators achieved technical efficacy and comparable costs as they gained skills and experience in treating a particular mill. Non-MB Mill Pest Control Findings
