Well some good guesses, and some dam right crazy ones
Anyway Tonitrophobia is the fear of thunder so well done to Topper very close. Agrizoophobia is wild animals but farm animals was almost bang on the money.
The other 3 nobody even got close, well apart from redDevil_UK with Amathophobia - fear of italian door mats but then he did use google to get that close
So come on the last 3 still stand
Amathophobia
Epistaxiophobia
Lachanophobia
