[quote=orchidgiants;243301]Thanks for all the responses and greetings!

Des - Why would we want to feed it with a lower nitrogen fertilizer now, during the grow season? . Des - can you recommend a good contact fungicide? We thought the Bayer would take care of most bacterial and fungal infections systemically, but perhaps we should switch to a contact fungicide instead.


My summer fertilizer has a 16% nitrogen content and I also foliar feed during warm nights with a seaweed fertilizer Fungi seem to enjoy a high nitrogen on your leaves and will initiate on a temperature drop especially if you still have water down the axle of the new growth.
We have cold snaps here even in mid summer which can play havoc especially with your Cymbid seedlings.
I try not to use a systemic product unless it really necessary, as it can result in crippled flowers .
I use Captab and dithane alternativly, evey two weeks as part of my prevention program it makes for cleaner leaves and fewer problems
