New wireworm control option available
BASF recently released their new wireworm seed treatment Teraxxa F4. Teraxxa F4 contains the active ingredient broflanilide and is applied at a rate of 5.0g active ingredient per 100kg of seed.
Recently, Dr. Willem van Herk (Research and Development Centre, Agriculture and Agri-Food Canada, Agassiz, British Columbia) and his research partners investigated the effects of broflanilide on wheat emergence and wireworm population reduction. Population control is measured by assessing the number of wireworms caught before and after treatment.
In 2012, initial research applied broflanilide at five times the rate found in Teraxxa F4. Those initial results indicated 87.3% reduction in wireworm populations. More intensive research was conducted in Agassiz from 2013 to 2019 utilizing the 5.0g active ingredient per 100kg of seed rate. Results indicated that at the 5g rate, broflanilide reduced the wireworm population by 79.8% while maintaining a plant stand of 82.7%. For reference, lindane provided a wireworm population reduction of 70%.
Broflanilide shows promise as a vital tool in the battle against wireworms in Alberta.
