The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Bioceres WP Biological Mycoinsecticide for reduction in numbers of whiteflies, aphids and thrips on the following greenhouse-grown crops: eggplant, lettuce, mint, onion and Brassica transplants, Asian water spinach and strawberries in Canada.

Bioceres WP Biological Mycoinsecticide was already labeled for use on a variety of crops in Canada for management of these pests. Its active ingredient is Beauveria bassiana strain ANT-03.

These minor use projects were submitted by Ontario and Quebec as a result of minor use priorities established by growers and extension personnel.


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 Bioceres WP Biological Mycoinsecticide.

Do not apply or allow drift of Bioceres WP Biological Mycoinsecticide to other crops or non-target areas. Bioceres WP Biological Mycoinsecticide is toxic to bees exposed to direct treatment or drift and may be toxic to some beneficial insects.  Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers.
