Four A5 Parties submitted their first nominations for MB use in One of the A5 Parties (Malaysia) withdrew its nomination before the MBTOC meeting in late March.

Ham producers should also be trained in IPM options, eg dips, traps, pesticides for crevices and cracks and heat and cold treatments. MBTOC notes that in the absence of alternatives that recapture facilities could be adopted to reduce emissions.

Party substantiated that substrates were uneconomical. Active research program in place. Dec. XX/V 4 requires the Party to provide an update of the research program progress to the 34 th OEWG.

MBTOC accepts that substrate technology is uneconomical at this time for later generations. Groundwater studies for a key alternative, chloropicrin, was to commence in December Party is required to provide an update to this OEWG as per Dec XXV/4.

M o n t r e a l P r o t o c o l O E W G m e e t i n g, J u n e , P a r i s MBTOC Interim Recommendation for 2016: t Party accepts that alternatives are available for the remaining MB use. The Party has indicated that this is the final nomination for this sector which has been one of the most difficult for uptake of alternatives, due to regulations.

The submission however did not provide data from studies within Argentina showing that alternatives were not effective for these sectors. This is a requirement of Decision IX/6. Further the request was for sectors where alternatives are proven effective.

MBTOC recommends a reduction of 6 t for protected ginger crops to align with the dosage rate used for outdoor ginger in China as 40 g/m 2 of MB is considered suitable for control of the target pathogens and weeds.

MBTOC considered clean planting material essential, despite the lack of an official certification requirement. The recommended amounts were reduced because extrapolated amounts beyond current usage are contingency amounts and were not recommended

Requests from A5 Parties in this round are in preplant soil sectors where target pathogens and the effectiveness of alternatives are similar to those in non A5 sectors. An exception is the submission for ginger from China (i.e. bacterial wilt). Difficult sectors in A5 countries are similar to those in non A5 countries (e.g. nursery sectors). Accounting frameworks are required next year by A5 Parties (Dec Ex. 1/4 (9f)) seeking any CUEs. Issues M o n t r e a l P r o t o c o l O E W G m e e t i n g, J u n e , P a r i s
