Again Bordeaux Mixture should work, but you must start spraying BEFORE any signs of trouble, it will help prevent, but won't cure. My intention is to start spraying within the next week. How frequently should I repeat the spraying, please? Every ten days to a fortnight. I always spray with a mixture of bordeaux and Dithane. One takes care of downy mildew and the other powdery mildew. Both these mildews can attack at any time and you can lose the whole crop. -- +-------------------------------------------------------+ | Internet: | writing from | | Fidonet: David Rance 2:252/110 | Caversham, | | BBS: telnet://mesnil.demon.co.uk | Reading, UK | +-------------------------------------------------------+ |
