Health Canada’s Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is granting registration for the sale and use of Pyrifluquinazon Technical and Pyrifluquinazon 20SC Insecticide, containing the technical grade active ingredient pyrifluquinazon, for the control of aphids and whiteflies in greenhouse vegetables and greenhouse herbaceous and woody deciduous ornamentals.
Pyrifluquinazon is an insecticide that acts on the insect nervous system. Pyrifluquinazon controls insects by acting as a feeding blocker that disrupts feeding in plant-sucking insects. This leads to starvation and death as the insects can no longer penetrate plants with their mouthparts. Pyrifluquinazon displays translaminar (local systemic) movement by entering one side of a leaf and moving to the other leaf surface when applied to foliage.
Pyrifluquinazon is the active ingredient in Pyrifluquinazon 20SC Insecticide, which controls aphids and whiteflies in greenhouse lettuce, cucumber, tomato, eggplant and pepper and greenhouse herbaceous and woody deciduous ornamentals. Aphids and whitefly are widespread and significant pests of greenhouse crops.
Pyrifluquinazon 20SC Insecticide can aid in resistance management of aphids and whitefly when used in rotation with other insecticides in integrated pest management programs. As pyrifluquinazon stops feeding by insects, it may also aid in reducing the transmission of insect-vectored plant viruses.
The Proposed Registration Decision PRD2022-15, Pyrifluquinazon and Pyrifluquinazon 20SC Insecticide, containing the detailed evaluation of the information submitted in support of this registration, underwent a 45-day consultation period ending on 30 November 2022. The evaluation found that, under the approved conditions of use, the health and environmental risks and the value of the pest control product(s) are acceptable. Health Canada received no comments on PRD2022-15, Pyrifluquinazon and Pyrifluquinazon 20SC Insecticide, during the public consultation period conducted in accordance with section 28 of the Pest Control Products Act.
