I have a row of arborvitae and the tips of the foliage have turned brown over the winter and have died. Now that things are greening up, it is more noticeable. Could this just be winter kill because it was so cold,or something else like a bug or disease? What can I spray on or action to take?

This does not look like insect or disease, but rather winter damage. Evergreens are showing a great deal of winter damage this spring because of a severe winter cold, made worse by a dry fall and winter.
Much of the dead foliage will drop off. Thoroughly dead tips can be pruned off, but you can just let it self-prune if you like. Damage will also be hidden by new spring growth. Be sure not to prune off tips that look dead but actually just need to put out new growth.
In the future, do not let your evergreens go into winter in dry soil. Be alert in the fall for dry weather and water.
Thank you very much for your prompt response. Ver
