September 14, 2012, Guelph, Ont – The Pest Management Regulatory Agency (PMRA) recently announced the approval of a label revision to allow Delegate WG use on bulb vegetables and tree nuts in Ontario, Quebec, Nova Scotia, Manitoba and Alberta.

In 2011 the PMRA granted an emergency use label expansion for Delegate WG on bulb vegetables to help onion growers manage the thriving population of onion thrips, which impact crop quality and yield. This 2012 label revision will permit growers to continue using this insect control option on a variety of bulb vegetables, including garlic, leek, dry bulb onion, green onion and shallot.

Delegate WG, a Dow AgroSciences product, provides control of a broad spectrum of insect pests in a variety of fruit and vegetable crops at lower use rates. Delegate is from the spinosyn chemistry class, a mode of action that provides control of targeted pests across multiple growth stages. It combines the favourable environmental profile of a biological product with the efficacy of synthetic technologies.

“This label revision will allow growers to elevate the performance of their bulb vegetables and tree nuts by using Delegate WG,” said Allan McFadden, research scientist with Dow AgroSciences Canada Inc. “Delegate does an excellent job of controlling insects like onion thrips. It’s the safe, effective control option growers have been looking for.”
