Quarantine Service Okays Use of Methyl Bromide for Crop Pest Control

By ZION Olalekan

Following a warning issued by the National Agency For Drugs Administration and Control (NAFDAC) to the effect that the agro-chemical, methyl bromide, has been phased out and its use in Nigeria is now prohibited because of the impact of the substance on climate change, particularly the depletion of the ozone layer, the National Agricultural Quarantine Service has asked stakeholders to discountenance such instruction.

Dr. Chigozie Nwodo the spokesman of NAQS in a statement sent to Nigeriamaritime360.com yesterday, said the announcement by NAFDAC has caused concern and panic among farmers and exporters who rely on Methyl bromide as potent option for the control of certain agricultural pests.

The statement reads in part “In the interest of clarity, we wish to state as follows:
Methyl bromide is a widely used gas fumigant for the control of insect pests, termites, rodents, weeds and some soil borne diseases”

“Whereas the use of methyl bromide is known to have some deleterious effect on the environment, it is acceptable for controlled quarantine use because of the lack of comparably efficacious alternatives. For example, under the International Standard for Phytosanitary Measures (ISPM) 15, the use of Methyl bromide for the treatment of wood packaging in international trade is allowed.

“More so, the use of methyl bromide is sometimes set as a precondition for the treatment of agro-commodities intended for export. Some destination countries specifically request for its use in the fumigation of a number of agricultural produce meant for export to their market. A case in point: Mexico, as a nation, explicitly requested that all Hibiscus shipments from Nigeria to their country must be treated with Methyl bromide. This is a clear and categorical precondition for the export of Nigerian Hibiscus to Mexico”.

Dr. Nwodo noted that healthy compliance with the necessary prerequisite enabled Nigeria to earn over $35 million in foreign exchange in the seven months of 2017 alone.

“For the avoidance of doubt, all agro-chemicals are potentially harmful; if used contrary to their original purpose or if applied arbitrarily. This is the reason NAQS advocates the use of agro-chemicals according to the appropriate product specification” he added.

Dr. Nwodo also argued that the NAQS is the statutory agricultural quarantine authority in Nigeria. It is mandated to promote and regulate sanitary and phytosanitary measures in order to minimize the risk to agricultural economy, food safety and the environment.

He said it is also within the sole purview of NAQS to make pronouncements on the permissibility or otherwise of the use of methyl bromide and other agro-chemicals for the phytosanitary treatment of agro-commodities.

“NAQS is the National Plant Protection Organization (NIPPO) for Nigeria under the International Plant Protection (IPPC) guidelines. The Agency is thus responsible for ensuring that Nigeria conforms to all relevant international protocols on agro-commodities that are consistent with the overall interest of the Nigerian agricultural economy.

“Consequently, farmers are advised that the healthy use of methyl bromide for control of agricultural pest remains permissible in Nigeria especially for export of Hibiscus to Mexico.
Any possible announcement of a change in the regime of the use of methyl bromide for agricultural pest control in the future will emanate from NAQS” he said.
