I believe you're referring to the speech Titania gives to Oberson, regarding the natural disasters that have occurred because of the jealousy between the two of them:
1. Fogs from out of the sea, pelting the land, causing rivers to flood;
2. The fields are all flooded and filled with mud and muck;
3. Corn (crops) have rotted in the fields;
4. Disease is in the air;
5. The seasons are changed around.
