Exploring Spray Drones in Soybean

White mould is caused by the fungus Sclerotinia sclerotiorum and it’s an annual threat to soybean when cool, wet conditions correspond with flowering. Variety selection (e.g. high tolerance) and cultural control (e.g. crop rotation and wider row width) are important management tools, but ultimately the application of a crop protection product between R1 and R2 […]

How to Succeed with a Soil Drench Application in Strawberries

In 2016, Ontario berry growers were surveyed to determine the typical spray volume they used to apply unspecified crop protection products. For strawberry growers (day-neutral and June-bearing), the results spanned 50 to 1,000 L/ha (~5 gpa to ~100 gpa). In an earlier survey (2013), respondents specified 250 to 650 L/ha (~26.5 to 70 gpa) for […]

Beluga Drop Hoses in Corn: Utility and Return on Investment (2023 Update)

In 2019 we evaluated the spray coverage from nine application methods on corn silks. The results showed that a directed application from drop hoses (aka drop pipes, drop legs) suspended in between the rows gave significantly higher deposits. The results led us to wonder if the superior coverage from a directed application translated to improved […]

Crop-Adapted Spraying – A Multiyear Study in Highbush Blueberry (2023 Update)

This case study is taking place on a 15 acre highbush blueberry operation in southern Ontario. In 2016, considerable pressure from spotted-wing drosophila (SWD) prompted the growers to make changes to their crop management practices and their spray program. They employed a three-pronged approach to improving crop protection: We have been tracking pesticide use, water […]

The State of Drone Spraying in Canadian Agriculture (2023)

In Canada, the use of drones for pesticide application, otherwise known as Remote Piloted Aerial Systems (RPAS), is regulated by two Federal Departments: Transport Canada establishes regulations for safe operation and Health Canada for the registration and conditions of use of pest control products. Drones are already used in Canadian agriculture for crop surveillance and […]
