Organophosphate and Carbamate Review
Bee non-contact periods
Recently the Environmental Protection Authority (EPA) notified us of a proposal to implement non-contact periods for certain organophosphate and carbamate plant protection substances in order 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 8 and 10 days respectively. Along with other industry groups Tomatoes NZ have 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 are continuing the recent OPC reassessment process and are currently 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 Initially dichlorvos was included in in the OPC reassessment but it was withdrawn in May 2012 as this compound has some non-plant protection uses and could not be considered with the other OPCs.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 issue their report. TomatoesNZ consider 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.
