The Pest Management Regulatory Agency (PMRA) recently approved a minor use label expansion registration for Purespray Green spray oil for management of several insects on various fruit crops in Canada. Purespray Green spray oil was already labeled for management of insects and diseases on a wide range of crops in Canada. These minor use proposals were submitted by the British Columbia Ministry of Agriculture and Food (BCMAF) 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 management decisions within a robust integrated pest management program and should consult the complete label before using Purespray Green spray oil.
