>> Greetings.
>> Are there any chemical sprays labeled for Iris which appear to be
>> effective against fungal leaf spot after it has manifested and had some
>> weeks to
>> develop? Obviuosly the spots are not going to go away, but is there
>> anything
>> which appears to arrest them and retard new outbreaks?
>> Is all chemical treatment of fungal leaf spot preventive in nature?
>> Is there any soil treatment which will help beat back spot other than
>> solarizing?
>> What do you personally do if you get a bad spot outbreak? Bloom is past,
>> the leaves look grody to the max, and there must be spores aplenty. Do
>> you
>> spray? Do you cut everything back to the ground? Prevention is better
>> than
>> cure, sure. but you did not prevent well enough, so, what now?
>> Thank you.
