Bringing you the latest advancements in aerial application, agronomy and crop protection.

Jonair (1988) Ltd. is owned and operated by Bryan Dion and Dave Frisch — your true independent.

Locally Owned and Operated

Based in Portage la Prairie, Manitoba, Jonair provides aerial applications to growers in Manitoba and Saskatchewan. Also, as part of a consortium, the company applies crop protection products to forests in Eastern Canada.

Our Ag pilots are highly trained professionals who hold commercial pilot licenses and provincial pesticide applicator licenses. They also offer over 100 years of combined service in the industry.

Our agronomists and pilots strive to maintain the most up-to-date knowledge of legislation, pesticide hazards and safe working procedures.

Jonair is proud to work with local growers and proud to support local community activities, sports teams and charities.


Bryan Dion

Bryan has 22 years experience at Jonair and over 24 years in the agricultural field. He has a Diploma in Agriculture from the University of Manitoba, is a Certified Crop Advisor, and a member of the Manitoba Aerial Applicator's Association (MAAA) and Canadian Aerial Applicators Association (CAAA). Bryan grew up on a dairy and grain farm, which enables him to connect with today's growers.


Dave Frisch

Dave started flying in 1999 and has been in flight ever since. His commitment to Ag piloting began at Jonair in 2001, and he still provides the best possible aerial applications. Dave is actively involved in the Manitoba Aerial Applicators Association (MAAA), the Canadian Aerial Applicators Association (CAAA), and is a member of the National Agricultural Aviation Association (NAAA).


Since 1988, Jonair has delivered advanced aerial application services to satisfied growers across Manitoba and Saskatchewan.

Benefits of Aerial Application

Because many products are only useful at specific pest and crop growth stages, Jonair applies crop protection products in a timely and efficient manner.

Our fleet of Air Tractors services large areas quickly, treating crops faster — which is critical for disease and pest control — and spraying more acres per day than ground machines.

Aerial application pays for itself and puts more money in a grower's pocket.

Our sophisticated Fleet

2 Air Tractor AT-502 B Aircraft

At 500-gallon capacity, this fast and efficient aircraft boasts state of the art Satloc GPS and advanced nozzle technology that helps ensure the practical application of product on crops and pests. This implementation allows for field navigation accuracy to less than a foot and application rate accuracy to 0.1 gallons per acre.

3 Air Tractor AT-502XP Aircraft

The Air Tractor 502XP has the Xtra Power to haul a full load even on the hottest days. It has a 500-gallon capacity and provides speed and high productivity.

2 Air Tractor AT-802A Aircraft

The AT-802A has a 800-gallon capacity and is the largest single-engine ag aircraft. It can complete more jobs in a single load and has the capacity to do the work of several smaller planes.

Guaranteed No Tracks

One of the most apparent advantages of aerial application is zero soil compaction.

Ground equipment driven through fields leaves wheel tracks and compacts soil particles. This invasive activity reduces pore space and restricts oxygen and water movement into and through the soil and root zone. Compaction can be particularly harmful on wet ground, sometimes making the soil hard and reducing yields.

Wet soils will never stop aerial applicators from spraying. Moving ground equipment through a field also inevitably damages the crop  — sometimes up to five percent of the plants. That damage can reduce crop yield much more than the cost of an aerial application.

Aerial applications also reduce the risk of diseases like club root from spreading field to field.


In addition to agricultural aerial applications, Jonair also protects forests and controls health-threatening pests.

Outbreaks of eastern spruce budworm occur regularly in the boreal, Great Lakes and Acadian forest regions of Eastern Canada. Jonair is part of a group of over 30 aircraft from Manitoba, Saskatchewan and Alberta that head to Quebec at the end of May to participate in a spray program to control the spruce budworm — a moth whose caterpillar feeds on trees.

The Budworm Program aims to maintain tree survival, preserve the annual allowable cut, and in some instances protect wildlife habitat and recreation value. Biological control using Bacillus thuringiensis (Bt) has made this program highly successful in reducing the budworm populations.

Jonair is dedicated to keeping our Canadian forests green and healthy.

Agronomy &
Crop Inputs

Agronomy is a branch of agriculture that studies the principles and practice of soil, water and crop management.

Benefits of a Jonair Agronomist

Our agronomists are knowledgeable about the latest technology and chemistry and can provide advice on the application of crop inputs for crop enhancement and protection.

Jonair agronomists continually scout fields to monitor for weeds, disease and insects throughout the stages of crop growth and advise growers of any issues during the growing season.

Our agronomists are also available to provide local farmers with assistance on future crop rotation planning.

Full Lineup of Crop Inputs

Jonair carries a full line of crop inputs from major manufacturers, including top yielding soybean, canola and corn varieties along with a wide range of seed treatments. Our crop protection products include herbicides, fungicides and insecticides.
