essential oils control botrytis cinerea aka Bud rot

[Kygiacomo!!!]

hey Ic i been doing alot of reading and research on what essential oils that inhibit the growth of the dreaded bud rot(botrytis cinerea). im sure they are many different recipes out there to prevent this disease..
i would just like to hear what others are useing or have read to help us all control this horrible disease..from my studies that i have found oregano, thyme,clover,rosemary,Eucalyptus, Lemongrass,fennel,black caraway and tea tree are the best..
i have thyme,clover and rosemary as of now but before i get anymore i want to see what u guys are useing or have heard about useing..
this is one disease that strikes fear in us all im sure..here is a few links to the research i been reading on and hopefully we all can come together here and have a good good positive debate on which to use..
im a guerilla grower and i have had to deal with this shit ever year, so hopefully this conversation will help us all this year as growing season is not to far away!

Ive also read some papers mentioning these oils and the compounds that may be responsible. We might have to try an experiment. I dont really want to spray my buds with fragrant oils though. Have you found anything out about this yet?

I was thinking the same thing sticky, adding oils doesn't seem to be something that would help with rot. The most I could see it doing is creating a moisture barrier, and not in a good way.

I've sprayed the bajeezus out of buds with SNS 244, homemade SNS 244, as well as this year buildasoil.com's essential oil blend, which they seem to have carefully selected and sourced the herbs for their maximum anti-fungal properties in the extract (so they say). at any rate, once bud rot takes hold not even blasting it with copper soap (aka Camelot O, or just bonide Copper Octanoate). These were not buds i planned on smoking, or even using, I was so fed up I just wanted to see what would kill the rot I had no plans on keeping the bud so i figured i might as well experiment. so i quarantined it and blasted it with everything under the sun. it worked ok, it slowed the spead of the rot, it allowed the buds to finish, but it gave a bizaare iridescent appearance to the leaves (maybe i over-applied). anyway, what i learned from this experiment is that the rot starts from the center, so before the buds are large enough to hide the main stem you could apply these oils and *maybe* they would keep that area un-inhabitable to mold reproduction, just a guess. time will tell. but its been a very dry summer as luck would have it i hope that trend continues.

interesting reading Kygiacomo!!! it is very hopeful reading, although unfortunate that they are only applying the research to post-harvest fruits as oppose to pre-harvest cannabis!

"Light microscopic observations revealed that the essential oils caused... morphological degenerations, such as cytoplasmic coagulation, hyphal shrivelling and protoplast leakage of the fungal hyphae."

hyphal shrivelling AND protoplast leakage. take that, Botrytis. stuck yr dick in the wrong oil sounds to me.
