Methyl Bromide
Soil Fumigation

Methyl bromide is a naturally occurring chemical which is produced by oceans,
forest and grass fires, and volcanoes. It also can be man-made. Manufactured
methyl bromide is used to fumigate buildings, soils and stored products.
|
 |
Methyl bromide in soil fumigation combats a
host of
devastating organisms and diseases. These include nematodes, soilborne fungi,
phytophtora, weeds
and diseases which attack roots and thus, destroy
and kill the
plants.
|
 |
Methyl bromide, when needed to
destroy
pests and diseases in the soil, is used at most once a year. (For trees and
vines, it is used only once every 10-30 years).
|
 |
Methyl bromide is used in the soil BEFORE
planting begins. For this reason, it does not come into contact with crops while
they are growing - and is not a food safety issue.
|
 |
California has extensive laws which are
administered under the
California Environmental Protection Agency - Department of Pesticide Regulation
(CALEPA/DPR) regarding the use of any pesticides in agricultural production.
CALEPA/DPR has monitoring and reporting programs to assure growers are abiding
by the laws.
|
 |
CALEPA/DPR also has developed and set forth
extensive permit conditions regarding the use of soil fumigants -- such as
methyl bromide -- to provide for the safety of farmers, farm workers and the
general public. These permit conditions include "buffer zones" which establish
the distances and more than a 100-fold margin of safety between applications and
any occupied structures including schools. The manual which governs over methyl
bromide applications is two-inches thick!

 |
Methyl bromide is a very important tool
which is used to protect structures from wood destroying pests, to protect
against the introduction of diseases and pests in ports and through shipping, to
preserve food after harvest from cockroaches, rodents, maggots, weevils, moths
and beetles, as well as in soil fumigation to protect plants including those
which provide vegetables, fruits and nuts.
|
 |
All tests on methyl bromide to date have
shown that it is NOT a carcinogen. In 1994, an independent scientific panel
appointed by the state to review data relative to pesticides decided by a 7-0
vote that the evidence does not support a determination that methyl bromide is a
reproductive toxicant.
|
 |
According to the University of California,
the loss of methyl bromide would cost direct losses to California business up to
$346 million per year, with 9,894 full-time jobs lost annually. Air freight
facilities and seaports in California depend upon the use of methyl bromide for
their very existence - their business would be transferred to other U.S. ports
and Mexico. Discontinuing the use of methyl bromide could also threaten
California's real estate market - as methyl bromide plays a key role in the
battle against termites and other wood-destroying pests.

 |
Methyl bromide, as well as other
agricultural chemicals, can only be applied by qualified application specialists
who have received extensive training in pest control and chemical usage.
Applications are monitored by county agricultural commissioners and must be
conducted in accordance with stringent state and federal regulations.
|
 |
The loss of methyl bromide will reduce our
ability to control food borne diseases such as Salmonella, E. Coli., etc.
carried by vectors such as cockroaches, rodents, maggots, weevils, beetles, etc.
|
 |
Methyl bromide increases the supply, quality, nutritiousness and safety of fruits, vegetables, nuts, grains and processed
foods. This leads to decreased rates of cancer, heart disease and other health
related problems.
|
 |
The loss of methyl bromide means a loss of
efficiency for American farmers, putting them at a competitive disadvantage to
farmers in other countries.
|
Ø
The loss of farming efficiency in
the United States means consumers can expect more imported food as well as
higher costs for food. It will also result in the loss of jobs in the U.S.
Ø
The loss of methyl bromide would
cost American farmers $1.3 billion annually, according to the U. S. Department
of Agriculture.
 |
More than 100 crops
benefit from methyl bromide.
