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 on various crops and crop groups 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 the British Columbia Ministry of Agriculture, Food and Fisheries (BCMAFF), and Ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Québec (MAPAQ) 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.
Rate (L product / 1000 L of water)
Crop Group 13-07 (Small fruit and berries) *
Control of Scale
Dormant to Green tip up to 1 cm green or first leaf. Foliar spray using ground application equipment only. For Lecanium Scale in highbush blueberry, apply one application as dormant spray in late winter. Use 1000L/ha for small bushes –1500L/ha for large bushes. Maximum of two dormant applications per year if summer spray applications are expected during the growing season. Apply at 7 – 14 day intervals.
Apples, Pears **
Control of Codling Moth
For codling moth overwintering, 1st summer and 2nd summer generations: apply at or just prior to first egg hatch and during egg laying. Apply every 7-14 days depending upon level of pest pressure. Do not exceed more than 10 L oil per ha per application for summer treatments. For apples and pears do not use oil within 14 days before or after captan fungicide. Do not apply as dormant spray.
Suppression of Leafhopper Nymphs
Eight (8) summer spray applications with a 10-14 day interval. Begin applications when eggs or small nymphs are present. Thorough coverage is essential. PHI is 14 days for table grapes as oil will remove bloom on grapes. On grapes, do not tank mix oil and copper more than once per season. Do not use copper and oil together with fruit present. Do not use oil within 14 days before or after captan fungicide.
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.
