The Pesticides Regulatory Directorate (PRD), formerly known as the Pest Management Regulatory Agency (PMRA), recently approved a minor use label expansion for Pyganic insecticide for suppression of onion thrips, and control of beet armyworm, leafhoppers, and climbing cutworms on Crop Group 3-07, Bulb Vegetables; and control of aphids, leafhoppers, climbing cutworms and cabbage looper on Crop group 25 Herbs and Crop Group 26. Pyganic insecticide was already labelled for management of insects on a wide range of crops in Canada. These minor use proposals were submitted by Agriculture and AgriFood Canada’s Pest Management Centre as a result of minor use priorities established by growers and extension personnel across Canada.
The following is provided as an abbreviated, general outline only. Users should be making insect management decisions within a robust integrated insect management program and should consult the complete label before using Pyganic insecticide.
Crop(s) | Target | Rate (mL product/ha) | Application Information | Pre-Harvest Interval (PHI) (days) |
CG 3-07 Bulb Vegetables | Suppression of Onion Thrips
Control of Beet Armyworm, Leafhoppers, and Climbing Cutworms | 2.32 – 4.65 L
| Do not reapply more often than every 3 days. Do not apply more than 10 times per season. Do not apply more than 46.5 L/ha (600 g a.i./ha) per season. For most cutworms, activity is greatest during the late evening and night. Application should be timed as close as possible to insect feeding activity. | 0 - The harvest of all labelled crops is permitted on the day of application. |
Crop group 25 Herbs Crop group 26: Spices
| Control of Aphids, Climbing cutworms, Cabbage Loopers, and Leafhoppers | 2.32 – 4.65 L
| Monitor for pest presence and apply when pests are first observed; do not wait until plants are heavily infested. Repeat application if necessary, as indicated by monitoring, but do not reapply within 3 days. Do not apply more than 10 times per year. Do not apply more than 46.5 L/ha (600 g ai/ha) per year. Apply in sufficient spray volume to ensure complete and thorough coverage of all plant surfaces. For most cutworms, activity is greatest during the late evening and night. Application should be timed as close as possible to insect feeding activity. Toxic to bees. Avoid application during the crop blooming period. If applications must be made during the crop blooming period, restrict applications to evening when most bees are not foraging. When using managed bees for pollination services, DO NOT apply during the crop blooming period. | 0 - The harvest of all labelled crops is permitted on the day of application. |
Follow all other precautions, restrictions, and directions for use on the Pyganic insecticide label.
