Fertilizing potatoes with ammonia

I was advised, as a fertilizer and protection against pests, to water and spray potatoes with an aqueous solution of ammonia (the one sold in a pharmacy, diluted in a volume of 10 ml of a 10% solution in a bucket of water). The potatoes are bright, gave a good leaf mass, bloomed profusely.

But I have a question. Wouldn't it be harmful to eat potatoes fertilized in this way later? All the same, ammonia is not exactly ammonium nitrate and I have never heard of it being used. Maybe this shouldn't be done?
