CPA residue reduction in Thailand. A case study of cypermethrin residue reductions in Thailand Burley
Cypermethrin has long been a problematic crop protection agent (CPA) in Thailand with residues over GRL’s being found in most samples since the early 1990’s. Through dedicated efforts by the tobacco industry stakeholders, including farmer education and awareness, on farm demonstrations & training, extensive CPA residue testing & eward schemes, cypermethrin residues have presented a year on year reducing trend 2010 through 2012. The main factors contributing to this being, increasing farmer awareness to the issues of cypermethrin and the residues seen in Thai Burley in particular, the threat to of loss of business and hence income for them and an incentive driven programme to reduce cypermethrin use have all contributed towards this reducing trend. Extensive sampling of farmer green tobacco through to processed Burley leaf from 2007-2012 has seen a shift in the Burley crop being over 60% non-compliant (> 1.00 ppm) to 72% complainant (< 1.00 ppm). The presentation details findings and actions taken to achieve this reduction on a national level through industry efforts and initiatives.
