There are virtually no weed free fields in western Canada organic or other wise.
Weeds have been spreading since the begining of agriculture even though farmers have been using lots of herbicides for decades. Singling out organic farms for an industry wide problem is unfair. Organic acres are very small proportion of total acres.
Herbicide tolerant weeds will be a bigger issue and have greater economic impact on crop production because the majority of farms use herbicides on the majority of acres. If that system fails then we are in big trouble.
All types of farms spread weeds unless they are completely weed free.
Most seed spread occurs because of poorly cleaned seed. Some of that is caused by inadequate on farm and elevator cleaners.
Road sides, yard sites, fencelines,sloughs, river valleys, pastures, hayland, all contain weeds and are generally not sprayed and are a potential source of weed seeds for neighboring fields.
Commercial trucks also spread weed seeds by dumping their gates wherever and leaving their tarps open while driving.
Organic screenings are often sold to feed companies and pelletized which is a good method of making sure they are not viable.
