Gekon Posted October 10, 2012 Report Share Posted October 10, 2012 Hello I have very annoying dome kind of mold in my terrarium. It allready killed 4 B. Guehoi seedlings and it seems to grow. I sprayed it several time with Bayer Garden Systhane Fungus Fighter but it doesn't seems to work. Can anyone recommend me a good fungicide? I searched here on forum but I couldn'y find the good one.

Gaz Posted October 10, 2012 Report Share Posted October 10, 2012 Hi Gekon, Is it a fuzzy grey mould? If so it could be botrytis which apparently thrives in humid or unventilated conditions. I had a some on my D regia seedlings recently, I lost a few but managed to save the rest by taking the propogator lid off the seed tray till they'd grown a bit. There's a write up about it here on the RHS website but basically they are saying that there aren't any chemicals licenced for use by amateur gardeners and treatment (according to them) relies on hygene, clearing up and improving ventilation. Other fungicides don't seem to touch it but some of the other growers here might know differently. Good luck Gaz Quote Link to comment Share on other sites More sharing options...
Gekon Posted October 10, 2012 Author Report Share Posted October 10, 2012 Its hard to explain how does to look like. It's like a gray fluff on top of the soil and around plants. I have quite powerfull fan in the terrarium and the humidity is not very high. It around 60-70%. Quote Link to comment Share on other sites More sharing options...
johns Posted October 10, 2012 Report Share Posted October 10, 2012 Is the fan on 24/7 or is it on the same timer as the lights? It might help to run it 24/7 if possible. Quote Link to comment Share on other sites More sharing options...
Gaz Posted October 10, 2012 Report Share Posted October 10, 2012 There's probably loads of info on the net but this site gives advice and a few pictures click here, have a look to see if it looks like your grey fluff..certainly sounds like botrytis though.

Gekon Posted October 10, 2012 Author Report Share Posted October 10, 2012 The fun tunr it self on automaticlly every 1hr. I think it's botrytis as well because of its hard to get rid of. Quote Link to comment Share on other sites More sharing options...
hddk Posted October 11, 2012 Report Share Posted October 11, 2012 Bayer Garden Systhane Fungus Fighter is myclobutanil and it's mainly for black spot, rust, powdery mildew. You can try using fungicides based on chlorothalonil and/or azoxystrobin (eg. Amistar by Syngenta), fenhexamid (Teldor by Bayer) or thiophanate methyl (Topsin by Nippon Soda). I don't know if they have the same names in UK. Does the fan blow fresh air into terrarium or is it closed inside and just stirs air? Maybe try to open terrarium from time to time...

sciabokho Posted October 12, 2012 Report Share Posted October 12, 2012 What helps for me is removing the symptoms by hand. I use a little wooden stick to remove all the green and grey and brown stuff. If the rest of the conditions are right, this should work. But you have to be tight and cautious and not let it grow out of hand. I don't like chemicals because they pile up in culture due to lack of streaming water.

dergeier7 Posted December 22, 2012 Report Share Posted December 22, 2012 Maybe a acidic growing medium,which would be in the optimal PH for most cps,could work better than same mold inhibitor I gess^^ Quote Link to comment Share on other sites More sharing options...
