I have a big problem going on right now and I am very frustrated! I haven't had a single sign of a plant pest in my grow until I planted a couple of seeds recently. I only planted a couple of them as a test thankfully, but I have a very limited number of them and am very scared to plant the others. My big plants are unfazed so far, thriving even, but all my seedlings and mid-sized(4-6 inch) plants have either died or are dying. I need to get flowering soon, but this setback has seriously hurt my plans to flower in waves. I've been pretty depressed about it.
Is it possible for fungus gnats to live dormant inside a seed? I ask because when one of the seeds broke the surface I noticed there was a hole forming in the side of it and eventually I saw a bunch of little white worms inside the seed. I checked my soil on all my plants and saw absolutely none of those. I just started to see gnats flying around though and like I said all my mid sized plants are fubar.
I normally use nicotine sprays to deal with this sort of problem, but some people have suggested that I should be worried about TMV. If I boil the tobacco into a tea for a sufficient amount of time would that kill any TMV that might be dormant in the brew? Does anyone know how tough TMV is outside of a host? I need to get my big plants cloned right now and I doubt that's going to work with gnats messing with everything. I can't figure out why the big plants aren't being killed like the little ones though. They have the same soil, but they also have a thick layer of "black forest mulch" over top of them that is mixed with cut up horsetail reeds and charcoal.
As soon as the problems started I sprayed 3-in-1 "organic" spray on them, put a layer of DE powder on top of the soil/mulch, and put out sticky strips. They still died....
