Ontario’s processing tomato growers have accomplished a unique goal. They have established the first grower-led program which collectively, as an industry, compiles a complete record of their crop protection use information. While growers of other horticultural crops keep records, they are not organized in the same format across the entire grower base. The industry-wide standard which has been established for this crop provides several advantages for growers. Being recognized by all processors is a good start. However, specifically for this article, they are ensuring that the regulatory system makes accurate decisions.
Recognizing the need for a real-time documentation and notification system for crop protection products, Tomecek Agronomy Services based out of Chatham, Ontario developed SprayHub in collaboration with the Ontario Processing Vegetable Growers (OPVG). The program can be accessed via mobile app or through a desktop computer. It is first and foremost a system designed for ensuring worker safety and food traceability.
The primary goal of the program is to keep track of product applications for restricted-entry intervals and pre-harvest intervals. Growers create a spray record for each field and application and the system automatically calculates and monitors these intervals. Multiple individuals can be added where there are multiple applicators or custom operators working on a farm. Farm employees and others who visit fields regularly can be instantly informed before entering any fields with entry restrictions. Fields can also be monitored at harvest for when the pre-harvest interval has been met. Growers consent to sharing their records with their processor and the grower association in aggregate form; confidentiality is assumed.
Initially developed with funding from Growing Forward 2 and the Ontario Tomato Research Institute, the operational cost of SprayHub is now covered directly by the processing tomato growers. Growers agree in their contract to use SprayHub. As a result, enrollment in the program is industry standard with approximately 65 growers enrolled in 2021. Growers support the costs of running the program through their licensing fees which currently run at seven cents per tonne of production. The OPVG collects and processes this payment on their behalf.
The program is now in its fifth year of operation having collected data since 2017. With a multi-year history of data now accumulating, a new benefit has emerged – the ability to produce comprehensive aggregate summaries of crop protection use information. This represents the average use of crop protection products on the crop across the industry. What additional benefits does this bring?
Regulatory decisions made by the Pest Management Regulatory Agency (PMRA) rely on estimating how much of a particular product is used by growers. Unfortunately, availability of this information, particularly for horticultural crops, is poor. When conducting a product re-evaluation, in the absence of updated use information, PMRA assumes the worst-case scenario: the maximum number of applications at the maximum label rate. This results in the estimated usage being higher than actual use -- many times higher would not be uncommon under this scenario.
