PURESPRAY GREEN® spray oil label expanded via Minor Use Program to help manage insects and powdery mildew on Crops Groups 25 (Herbs) and 26 (Spices)

By Josh Mosiondz, Minor Use Coordinator, OMAFRA

The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for PURESPRAY GREEN® spray oil for management of numerous insects and powdery mildew on Crop Groups 25 (Herbs) and 26 (Spices) in Canada. PURESPRAY GREEN® spray oil was already labeled for management of insects and powdery mildew on a wide range of crops in Canada. These minor use proposals were submitted by Ontario Ministry of Agriculture, Food, and Rural Affairs 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 insect and disease management decisions within a robust integrated pest management program and should consult the complete label before using PURESPRAY GREEN® spray oil.

Crop(s)TargetRate (L product / 1000 L of water)Application Information
Croup Group 25 (Herbs) (field and greenhouse)   Crop Group 26 (Spices) (field and greenhouse) Suppression of powdery mildew (Podosphaera spp.) on crops that are susceptible to these diseases; suppression of mites; deter the feeding of aphids10Mites, aphids: begin when mites and/or aphids appear. Minimum reapplication interval of 7 days. Powdery mildew: begin when conditions are favourable for disease development and/or when first symptoms appear. Reapplication interval of 7 – 14 days.

TOXIC to aquatic organisms. Observe BUFFER ZONES specified under DIRECTIONS FOR USE. To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water body. For terrestrial uses: Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high-water mark. Do not contaminate water when disposing of equipment washwater or rinsate. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas.

Follow all other precautions, restrictions, and directions for use on the PURESPRAY GREEN® spray oil label carefully.
