October 15, 2014, Calgary, Alta – Maximum Residue Limits (MRLs) for Delegate Insecticide have been established in Japan effective immediately. That means Canadian potato producers who grow product that could be destined for export to Japan can now apply Delegate for control of Colorado potato beetle and European corn borer.
“There has been a five to 10 per cent annual growth in imports of frozen potato products in Asia the last several years,” says Mark Alberts, product manager for horticulture with Dow AgroSciences. “Export markets are really important to potato producers so establishing foreign residue tolerances for potatoes is critical to Canadian growers. Now they have the peace of mind they can apply this excellent product without compromising where they can sell their crop.”
Delegate is from the spinosyn family of chemistry, which features a mode of action that controls insects two ways – through ingestion and contact – for knockdown and residual activity. It is active on insects across multiple growth stages. The company reports that insects stop feeding within minutes. Spinetoram, the active ingredient in Delegate, is derived through the fermentation of a naturally occurring organism.
Delegate can be used as a tool for potato growers managing neonicotinoid resistance in seed treatments. Delegate’s mode of action affects the insect’s nervous system in a manner different than other classes of chemistry. Delegate is formulated as a wettable granule and is labeled for a maximum of three applications per year.
