Introduction
Welcome to the Health Canada Pest Management Regulatory Agency’s Vertical Farming Stakeholder Questionnaire. The Pest Management Regulatory Agency (PMRA) is the Canadian government agency responsible for the regulation of pest control products, or pesticides, in Canada. To participate in the questionnaire, you should be either an owner or operator of a commercial vertical farm in Canada. One response only per vertical farm is requested.
What kind of information is being sought?
The purpose of this questionnaire is to obtain a snapshot of the vertical farming industry that will help inform the PMRA’s strategy to support the safe and effective use of pest control products in commercial vertical farming facilities.
You will be asked for information about aspects of your growing facility, production system, crops and pest pressures.
The PMRA will use the information gathered with this questionnaire to develop an appropriate approach to assess potential exposure and risks associated with the use of pest control products.
There are currently no pest control products registered for use in vertical farming operations in Canada. For more information, see Information Note: Vertical farming and pest control products (Appendix A).
What does Health Canada/PMRA consider to be a vertical farm?
To determine if your facility would be considered a vertical farm, please consult the following features of a vertical farm:
produces crops grown in appropriate media, for instance hydroponically, aeroponically or in soil;produces crops grown indoors on vertically stacked or inclined layers and/or integrated in other vertical structures, andrelies solely or largely on artificial lighting.
Can a greenhouse be a vertical farm?
Vertical farming differs from greenhouse production. In a greenhouse, plants are generally grown in a single layer on horizontal benches, containers or troughs placed on the ground and rely largely on natural sunlight. Vines, like tomato or cucumber plants, may grow vertically but are not considered vertically farmed if all plants are placed on one layer.
If you wish to participate in the questionnaire but are uncertain if your facility would be characterized as a vertical farm, please feel free to contact the questionnaire team at [email protected] for clarification.
What is a pesticide in the context of this questionnaire?
A pesticide or pest control product is any product used to directly or indirectly control, destroy, attract or repel a pest or prevent the pest’s injurious, noxious or troublesome effects.Pest control products contain active ingredients that can be substances, living organisms (for example, a beneficial species of bacteria or fungi) or other materials (ozone, chemical fungicide/insecticides) that exert these effects.Pest control products may be applied to plants or soil, or be used for surface, air or water sanitization in the presence or absence of crops.In Canada, pest control products are identified by a Pest Control Products Act (PCPA) registration number, which will appear on the product label in this format:
‘Registration number: ##### Pest Control Products Act’
Participation in the questionnaire
Thank you for taking time from your schedule to participate.
Pesticide free? If your goal is to produce vertically farmed crops without the use of pesticides, we also would like to hear from you. The goal of the questionnaire is to understand the vertical farming industry in Canada, which includes vertical farms that are “pesticide-free”.
By providing your responses to the questionnaire, you acknowledge that your participation in the questionnaire is voluntary, and you are at least 18 years of age. You may choose to terminate your participation in the questionnaire at any time and for any reason by contacting the questionnaire team at [email protected].
Any personal information (names and contact information) provided as part of the data collection process will not be used to inform decisions or be made publicly available. Please see the Privacy Notice.
START OF THE QUESTIONNAIRE
PLEASE FEEL FREE TO SKIP QUESTIONS IF YOU DO NOT KNOW OR DO NOT WISH TO PROVIDE AN ANSWER.
The questionnaire should take about 25 minutes to complete.
The following questions relate to pest pressures in the vertical farm. Pest pressures affect the type of pesticides that may be useful in a vertical farm, the frequency of their use and their efficacy. Your answers to these questions will help the PMRA understand existing needs and focus resources and efforts.
1. Please rate your level of interest in the following pesticide types for use in the vertical farm.
Level of Interest : 0=not interested, 5=highly interested.
Select ‘0’ for all choices if no pesticides will be used in your vertical farm.
Select ‘ND’ if you are undecided or you do not wish to respond.
*Microbial biopesticides contain living microorganisms or viruses that are used for pest management. They do not include predatory or parasitic insects/mites used for biological control.
*Non-conventional pesticides include food items, extracts, preservatives or additives (e.g. garlic powder); plant extracts and oils (e.g. vegetable or mineral oils); commodity chemicals that have a range of non-pesticidal uses (e.g. acetic acid, table salt, citric acid); fertilizer or other plant growth supplements commonly used in the agricultural sector (e.g.mineral salts, such as sodium, and potassium salts of phosphorus acid); or inert materials (e.g. diatomaceous earth) that have pesticidal uses.
*Conventional pesticides include chemicals that are synthesized by industry for pest management purposes.
*Surface sanitizers for equipment’ are pesticides that are meant to be applied to hard structures in the plant production area to prevent or control pests. While they may be applied either in the presence or absence of plants, they are not intended for application to plants.
*Air or water sanitizers’ are pesticides that are released into the air or water in the plant production area to prevent or control pests that live or move there. While they may be applied either in the presence or absence of plants, they are not intended for application to plants. Includes UV devices but does not include physical sanitization devices like a HEPA filter.
*Post harvest clean-up refers to application of pesticides (spray or fog) to plant material after the crop has been fully harvested but before the unusable plant material has been removed.
