before treatment because the presence of bark on the wood affects the efficacy of the methyl bromide treatment. For HT, the removal of bark can be carried out before or after treatment. In HT method the wood packaging material must be heated in accordance with a specific time–temperature schedule that achieves a minimum temperature of 56 °C for a minimum duration of 30 continuous minutes throughout the entire profile of the wood, including at its core.
In MB method the wood packaging material must be fumigated with methyl bromide in accordance with a schedule that achieves the minimum concentration-time product (CT) over 24 hours at the temperature and final residual concentration.
Unfortunately, in Pakistan HT method of wood treatment does not exist while MB method depletes ozone. On the other hand, being signatory of Montreal Convention, Methyl Bromide wood treatment method can be used only in special cases. Thus in general this method cannot be applied for wood treatments.
Director General Plant Protection Department Pakistan, Dr Mubarik Ali talking to The News said that they were aware of the situation and has already taken up the issue with ministries concerned, adding that letters have been written to the ministries to create awareness among the textile exporters to address the issues.
“We are also working to hold a high level meeting with Ministry of Commerce, Ministry of Food Security, Ministry of Textile and others involved to resolve the issue amicably,” Dr Mubarik said.
Talking about number of consignments returned from the EU due to untreated wooden packaging issue, he said they are around 14, 15 but correct numbers can only be declared after checking the records.
He further said that it is impossible for plant protection department to physically inspect thousands of export containers, besides the department does not issue phytosanitary certificate to the textile products. It only provides phytosanitary certificate for the wooden packaging and it is the responsibility of the exporter as well as the textile industry to look into the matter.
He accepted that the HT method for woods does not exist in Pakistan and long term working is required to make it available.
