Are you saying to yourself – Betsy Lamb has lost her mind, we don’t have chrysanthemums, yet?  Both may be true.  However, based on last year, if you have overwintered chrysanthemums in a garden, it is possible that you can have CWR in June.  Go out and check them now.

Pest Alert information – including an updated fungicide list is available at https://nysipm.cornell.edu/agriculture/ornamental-crops/pest-alerts/chrysanthemum-white-rust/

Thanks to Margery Daughtrey for all her help.

I’ll send another reminder when you have chrysanthemums coming in.  Remember that the fungicides are protectants, not curative.
