The Pest Management Regulatory Agency (PMRA) in Canada has granted Dow AgroSciences upgraded approval for Closer insecticide use to actively control Woolly apple aphid in pome fruit crops. 

“Canadian apple growers who have used Closer in the past know of its exceptional speed and ability to knockdown aphids. This upgraded designation reinforces the quality and efficacy of Closer and we are pleased that the PMRA has responded to the ongoing need to control insect infestation,” explains Tyler Groeneveld, category leader, Horticulture with Corteva Agriscience. 

This approval is significant as it gives growers greater access to a highly effective product that combats sap-feeding insects at various stages of growth and outbreak. Insects such as Woolly apple aphid can cause extensive crop damage, ultimately impacting the quality and value of orchard crops. 

Closer insecticide, powered by Isoclast active, is a revolutionary product ideal for control of both resistant and non-resistant pests, delivering the active ingredient sulfoxaflor, which is classified by the Insecticide Resistance Action Committee as the sole member of IRAC Subgroup 4C sulfoximines. The active ingredient moves quickly through the plant and has excellent systemic and translaminar activity that controls insect pests both on contact and by ingestion. The results are fast knockdown and residual control of aphids and other sap- feeding insects. 

Closer is highly selective and has minimal impact on beneficial insects. The properties and overall spectrum of activity of Closer insecticide make it an excellent fit for treatment when outbreaks occur as well as part of Integrated Pest Management Programs (IPM) to minimize flare-ups.
