By: Jim Chaput, OMAFRA, Minor Use Coordinator, Guelph

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 greenhouse-grown eggplant, lettuce, mint, onion and Brassica transplants, Asian water spinach and greenhouse-grown strawberries in Canada. Bioceres WP Biological Mycoinsecticide was already labeled for use on a variety of crops in Canada for management of these pests.

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.

Crop(s) Target Rate Application Information
GH lettuce, GH eggplant, GH mint, GH onion transplants, GH Brassica transplants, GH Asian water spinach, GH Strawberries Reduction in numbers of whiteflies, aphids and thrips Apply at a concentration of 2-4 g BIOCERES G WP/L water depending on insect population density. Use spray volume sufficient to cover foliage infested with insect pests. Crop size and spray equipment will determine spray volume needed. Depending on crop treated 500 to 1000 L of spray volume will typically be required for 1 ha.  Reapply at 7 day intervals or at 3 – 5 day intervals if pest pressure is high.  Pre-harvest interval is 0 days.

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.

Follow all other precautions, restrictions and directions for use on the Bioceres WP Biological Mycoinsecticide label carefully.
