October 30, 2008, Guelph, Ont. –
The Pest Management Regulatory Agency (PMRA) recently announced the
approval of registrations for potatoes in Canada for Matador and
Warrior (cyhalothrin-lambda) insecticides for control of the true
armyworm species Pseudaletia unipuncta.
 The PMRA also announced the approval of registrations for leaf lettuce for these products for the control of tarnished plant bug.
The active ingredient cyhalothrin-lambda was already labelled on a wide range of crops including grains, oilseeds, vegetables and fruits. Note that Warrior will eventually replace Matador in the marketplace.
Management of true armyworm has become a more serious problem affecting potatoes in Ontario and other nearby provinces such as Quebec. Tarnished plant bug is an annual, serious pest of leaf lettuce wherever lettuce crops are grown. Matador and Warrior were only labelled previously on head lettuce.
For copies of the new minor use labels, contact Jim Chaput, OMAFRA , Guelph (519) 826-3539, Eugenia Banks, OMAFRA potato specialist at Guelph (519) 826-3678 or visit the Syngenta Canada website at http://www.syngenta.ca.
