In 1992 the MOP (Copenhagen) established MB as a controlled
ODS. Deadlines for phase-out were agreed separately for
A5 and non-A5 Parties

Controlled consumption in Latin
America 2009
• Six countries account for 97% of the regional
controlled consumption: Mexico, Guatemala
Honduras Argentina Costa Rica and Chile.
• The main sectors using MB are cucurbits,
strawberries and tomatoes.
• All countries are in compliance with MP obligations.
• Brazil a large user in the past (>1000 tonnes) now
phased out. Cuba, the Dominican Republic and other
previous mid to large users have also phased-out.
• All Caribbean countries are LVC or report zero
consumption
Impact of MB phase-out
• The Montreal Protocol has brought changes in agricultural
practices in both developed and developing countries
• Technically feasible alternatives to MB exist for virtually all
previous uses.
• Combination of practices/ alternatives has been shown as the
best way forward - the long term benefits of wide spectrum
fumigation are questionable.
• Implementation of new options for soil pest management may
require changes in attitude/ strategies but is not necessarily
difficult, and often proves cheaper over time.
• Technology often comes from developed countries but
adaptation and successful adoption have proven possible
Agriculture, particularly horticulture is
undergoing significant changes
• As shipping methods to distant markets improve, production
increasingly shifts to the tropics and subtropics. Climate allows
for year-round production without wide cost variation, plus
labor is available and comparatively cheap.
• However, challenges are brought by
– Lower land availability - land costs more, soil is “tired” or too
infested after continuous monoculture!! - Control measures are
required
– Fewer chemicals are available, particularly MB, but others not
registered or undergoing review
– Concerns have reached consumers who now demand high quality
products grown within an environment-friendly framework. This
may include not using MB for soil fumigation
The QPS exemption for MB
• Article 2H of the Protocol (Copenhagen, 1992)
specifically excluded QPS from control measures, since
at that time no alternatives to MB for a diverse range of
treatments carried out for QPS were available.
• Although QPS was about 10% of global MB
consumption at the time, this was still significant in
allowing inter- and intra-country trade in commodities
treated with MB in the absence of site-specific
alternatives.
• Parties are nevertheless urged to use alternatives to MB
for QPS and to reduce emissions and use of MB
whenever possible
Definition- Quarantine
a) Quarantine applications, with respect to methyl
bromide, are treatments to prevent the introduction,
establishment and/or spread of quarantine pests
(including diseases), or to ensure their official control,
where:
–
Official control is that performed by, or authorized
by, a national plant, animal or environmental protection
or health authority;
– ii. Quarantine pests are pests of potential importance
to the areas endangered thereby and not yet present
there, or present but not widely distributed and being
officially controlled
i.
Definition - Pre-shipment
(b) "Pre-shipment applications" are those treatments applied
directly preceding and in relation to export, to meet the
phytosanitary or sanitary requirements of the importing
country or existing phytosanitary or sanitary requirements of
the exporting country;
 The definition of 'Pre-shipment' is unique to the Montreal Protocol.
(Decisions VII/5 and XI/12). Decision XI/12 declares that pre-shipment
applications are "those non-quarantine applications applied within 21
days prior to export to meet the official requirements of the importing
country or existing official requirements of the exporting country”.
 Official requirements are those, which are “performed by, or authorized
by a national plant, animal, environmental, health or stored product
authority".
Reasons for using MB for QPS
• Use of MB for QPS for commodity treatments is mostly
associated with international trade where regulations are
imposed by the importing country on the exporting
country.
• Some countries prefer to treat products upon arrival (at
import)
• MB is used in response to either pests found during
inspection and/or needed for a phytosanitary certificate,
which requires the commodity to be free from quarantine
pests.
• The driving force for what treatments are required,
allowed or not allowed, are those of the importing
country
Examples of QPS treatments
• Fumigation of cut flowers of fresh produce found to be infested
on arrival in the importing country with quarantine pests
(quarantine treatment);
• Fumigation of fruit before export to meet the official
phytosanitary requirements of the importing country for
mandatory fumigation of an officially-listed quarantine pest
(quarantine treatment);
• Fumigation of grain before export to meet the importing
country’s existing import regulations that require fumigation of
all export grain consignments (pre-shipment treatment);
• Fumigation of log exports either prior to shipment or on arrival
against official quarantine pests.
Pros and cons of MB as a QPS treatment
• Rapid speed of treatment.
• A high level of toxicity to humans;
• Low cost for fumigation;
• Odourless, difficult to detect;
• Relatively non-corrosive and applied
easily to shipping fumigation facilities,
containers or to bagged, palletised or
bulk commodities ‘under sheets’;
• A significant ODP;
• A long history of recognition by
quarantine authorities;
• Broad registration for use;
• Good ability to penetrate into the
commodity where pests might be
located;
• Rapid release of gas from the
commodity after exposure;
• Adverse effects on some
commodities, i.e. loss of viability,
quality reduction, reduced shelf life
and taint;
• Slow desorption from some
commodities and at low
temperatures, leading to hazardous
concentrations of MB in storage and
transport;
• Excessive bromide residues retained
in some product.
Key issues regarding MB use for QPS
• In 2009 QPS consumption was 46% higher than non-QPS
consumption. This is the first time that exempted uses exceed
controlled uses. QPS has become “the largest unregulated
emissive use of all ODS”.
• Increased use of MB for QPS is offsetting gains made by
reductions in controlled uses for soils, structures and
commodities.
• On the basis of use appraisals and currently available technologies
to replace MB for QPS, TEAP estimated that about 31% of global
consumption of MB for QPS reported in 2008 was immediately
replaceable.
• Some Parties have stopped all uses of MB including QPS (e.g. the
EU) and others have announced their intention to stop QPS use in
the near future (e.g. Brazil).

Main QPS uses
• In response to Dec XX/6 TEAP determined that four uses
consumed more than 70% by weight of the methyl
bromide used for QPS in 2008:
•
•
•
•
1) Sawn timber and wood packaging material (ISPM-15)
2) Grains and similar foodstuffs
3) Pre-plant soils use and
4) Logs.
• On the basis of these estimates, TEAP calculated that 31 to
47% of MB consumed for QPS in these four categories
were replaceable globally with immediately available
technologies. This represents about 31% of total global
use.

Tracking QPS use
• It is often difficult to track the actual use of MB after
import
• There is always a risk for QPS MB to end in a nonauthorized controlled use.
• Tracking systems are in place in many countries.
• QPS treatment performed under official control
• Some countries have registered different formulations for
QPS (100% MB) and controlled uses (98:2, 67:33, 50:50)
WTO and MB use
• WTO rules do not allow a country to require MB where another
treatment gives adequate phytosanitary protection.
• Countries have the right to adopt measures for the protection of
human, animal or plant life or health provided that the measures
are applied only to the extent necessary, based on scientific
principles and risk assessment.
• Members may adopt measures that give a higher level of protection
than international standards if there is scientific justification or as
a result of rigorous risk assessments
• Measures must be applied consistently across all their trading
partners and even within their own territory.
• Parties to the WTO agree to recognize and accept treatments which
shown to meet the required level of quarantine security.
• Countries may also choose to apply any available treatment that is
approved.
EU quarantine legislation allows many non-MB alternatives
Example of activities: ISPM-15 in the EU
• In 2002/3 TEAP and USDA highlighted risk of large increase
in MB use due to ISPM-15
• Several EU companies set up facilities for heat treatments,
NL provided seed funding
• The European Commission distributed paper about ISPM15 alternatives, held discussions with wood pallet
industry.
• Wood pallet industry agreed to reduce MB
• Presently >1,800 registered heat treatment facilities
• Many suppliers of pallets that do not need MB or heat
treatment: plastic pallets, cardboard, other materials
