mosquito dunks for fungus gnats on seedlings?
My flats of seedlings have fungus gnats which are stunting the growth of the plants. I read that the most non-toxic remedy is bacillus thuringiensis. I have some mosquito dunks which have that in them, but they dissolve slowly and I'm not sure what proportion to use. I doubt it would harm the plants to put too much BT on them but I want it to be strong enough to be effective and to work quickly. Do you think it would be a waste of time to try this? I have no idea what liquid BT would cost. Or maybe you have a different remedy for fungus gnats. They also have aphids and I haven't sprayed anything for that yet because I didn't want to do too many things at once to my seedlings. I potted them up a few days ago.
