The Pest Management Regulatory Agency (PMRA) recently announced the approval of minor use label expansion registrations for XenTari® WG Biological Insecticide for control of box tree moth on boxwood, for control of cabbage looper, corn earworm, and leafrollers on greenhouse strawberries and for control of tomato leafminer (Tuta absoluta) on fruiting vegetables in Canada. XenTari® WG Biological Insecticide was already labeled for use on a wide variety of crops in Canada for control of many caterpillar pests.
These minor use projects were submitted by Ontario as a result of minor use priorities established by growers and extension personnel. Box tree moth was also the subject of an emergency use approval in spring 2019 in response to the first outbreak of box tree moth in Canada.
The following is provided as an abbreviated, general outline only. Users should be making pest management decisions within a robust integrated pest management program and should consult the complete label before using XenTari® WG Biological Insecticide.
