I would suspect that he was allergic to the plant, rather than have a foxtail up his nose. I have seen my dogs sniff or bite a plant and then they would sneeze a lot. My Chewy just had a foxtail taken out of her ear, poor baby. But they don't usually go up the nose. I live in the country and we are covered with foxtails all over. There is no escaping them. Your baby will be okay in a few hours, I'm sure. Wash his face and nose and rinse it well. That will help. Good luck.
