Droning On and On – RPAAS Pilot Certification in Canada

In Canada, the use of drones for pesticide application, otherwise known as Remote Piloted Aerial Application Systems (RPAAS), 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 […]

In 1977, David Shelton and Kenneth Von Bargen (University of Nebraska) published an article called “10-1977 CC279 Gear Up – Throttle Down”. It described the merits of reducing tractor rpm’s for trailed implements that didn’t need 540 rpm to operate. In 2001 (republished in 2009), Robert Grisso (Extension Engineer with Virginia Cooperative Extension) described the […]

Centrifugal and Diaphragm Pumps

Adjusting Sprayer Settings Operators are encouraged to adjust airblast sprayer settings to conform to the variability in canopy size, density, spacing, and weather conditions. The efficiency and accuracy of the application is improved through the regular and independent adjustment of travel speed, nozzle output, and air settings. Inflexible sprayer design results in a suboptimal match […]
