Re­view of organophos­phates, car­ba­mates

NZ Grower - - Product Group Tomatoes Nz -

Re­cently the En­vi­ron­men­tal Pro­tec­tion Au­thor­ity (EPA) no­ti­fied us of a pro­posal to im­ple­ment non­con­tact pe­ri­ods for cer­tain organophos­phate and car­ba­mate plant pro­tec­tion sub­stances to pro­tect bees and other in­sect pol­li­na­tors.

For the com­pounds of in­ter­est to Toma­toes NZ, the EPA is propos­ing non-con­tact pe­ri­ods* for methomyl and ox­amyl of eight and 10 days re­spec­tively. Along with other in­dus­try groups Toma­toes NZ has en­gaged Mar­ket Ac­cess So­lu­tionz to re­view the cur­rent use of methomyl and ox­amyl and pro­vide ben­e­fit and im­pact in­for­ma­tion to the EPA on the pro­posed non-con­tact pe­ri­ods. The sub­mis­sion will be based around propos­ing that cur­rent good agri­cul­tural prac­tices used for th­ese com­pounds in the green­house do not have ad­verse ef­fects on bee or other in­sect pol­li­na­tor health. *Non-con­tact pe­riod – the pe­riod of time that must elapse be­tween ap­pli­ca­tion of a sub­stance onto a plant or tree, and when that plant or tree be­gins to flower. Trade names of prod­ucts that in­clude the ac­tive in­gre­di­ents listed above are: Methomyl: ORION, METHOMYL 200SL, DuPont, Lan­nate L in­sec­ti­cide Ox­amyl: DuPont Vy­date L ox­amyl in­sec­ti­cide/ne­mati­cide


The EPA is con­tin­u­ing the re­cent OPC re­assess­ment process and is re­assess­ing the use of dichlor­vos. Ini­tially dichlor­vos was in­cluded in in the OPC re­assess­ment but it was with­drawn in May 2012 as this com­pound has some non-plant pro­tec­tion uses and could not be con­sid­ered with the other OPCs. Again, Toma­toes NZ is in­volved in pro­vid­ing use pat­tern and ben­e­fit in­for­ma­tion to the EPA ahead of the for­mal re­assess­ment. A sub­mis­sion will then be made once the EPA is­sues its re­port. To­ma­toesNZ con­sid­ers the use of dichlor­vos to be crit­i­cal in pro­duc­tion of green­house toma­toes. Trade names of prod­ucts with dichlor­vos as an ac­tive in­gre­di­ent are Nu­vos and Di­vap.


The To­ma­toesNZ web­site is be­ing re­de­vel­oped to make it more user friendly, ap­peal­ing and more in­for­ma­tive. Once the new web­site is launched pass­words will be re­set to email ad­dresses for those with email ad­dresses. TNZ mem­bers will be no­ti­fied when this change is due to take place and also be given con­fir­ma­tion of pass­words. If you think we may not have your most cur­rent email ad­dress or do not have an email ad­dress for you at all please con­tact Lynda Banks on 04 494 9981 or email


At the re­cent AGM, TNZ mem­bers have gave man­date to pur­sue sign­ing the GIA Deed which in­cludes closer en­gage­ment be­tween MPI and in­dus­try on im­prov­ing biose­cu­rity sys­tems, joint decision mak­ing on pre­par­ing for and re­spond­ing to pest/dis­ease in­cur­sions and shar­ing the costs of th­ese ac­tiv­i­ties be­tween Gov­ern­ment and In­dus­try. In or­der to sign the GIA Deed an or­gan­i­sa­tion must be a le­gal en­tity. Cur­rently TNZ is not a stand-alone le­gal en­tity and ef­fec­tively op­er­ates like a ‘branch’ of HortNZ. As the most ap­pro­pri­ate type of le­gal en­tity for TNZ to be­come is an In­cor­po­rated So­ci­ety we are cur­rently work­ing through the de­tails of this. The TNZ com­mit­tee are of the opin­ion that be­com­ing an In­cor­po­rated So­ci­ety is not in any way a means of dis­so­ci­at­ing TNZ from HortNZ and the cur­rent re­la­tion­ship will be main­tained. Once the In­cor­po­rated So­ci­ety has been formed an ap­pli­ca­tion is then made to the min­is­ter to sign the GIA Deed. There are still some ma­jor and com­plex de­ci­sions to be made go­ing for­ward with re­gard to GIA such as in­dus­try ver­sus gov­ern­ment por­tion of cost shar­ing, how in­dus­tries are val­ued and the sub­se­quent ap­por­tion­ment of costs be­tween them and de­tails of any Op­er­a­tional Agree­ments (OAs) with re­gard to spe­cific pest in­cur­sions. We are part of th­ese dis­cus­sions and will keep you in­formed of fur­ther de­tails as they are fi­nalised.
