Given the appearance of the foliage as well as the timing and location (near farm fields), we strongly suspect this is herbicide drift damage. (Though if weed killers were used in your yard in this area, that also explains the symptoms.) Drift occurs when wind or water move the chemical beyond the boundaries of where it was applied. Certified applicators are trained to avoid drift and in general should not be applying pesticides on breezy or wet days. Nothing can be done about damaged tissue except to let the plant outgrow it in time. You can prune off the distorted stems or leave them; it's your choice and won't impact the roses in any measurable way.
