Full Version: Thrips ,Cannabis ,Sulphur (Dioxide)
Ive had a prob with thrips for a while , after finding a bud wich looks like its top has been munched - will post pic l8ter due to camera being dead, i have decided that it might be a good idea to switch the ex fan off and burn some sulphur in there to produce a atmosphere of So2 is this a good idea or should i avoid it like the plague?
Burning Sulfur creates a vapour that alters the pH of the leaf surface which controls powdery mildew and only slows the breeding process of insects.
I don't think this will get rid of your thrips entirely and may damage your crop, taste or health of.
Are you sure you have thrips? they tend to eat the leaves leaving a bleached dappled look to the leaves. I'm not sure they would be capable of eating an actual top.
How long left have you got to go? If not very long I would consider leaving it, then when the grow room is empty, fumigating the grow room with a smoke bomb device and general other cleaning.
If you have only just started flowering you could spray the actual plants with some product designed for thrips etc.

The reason i wanted to try So2 is because ive only got 2,ish weeks to go seed packet said 6 weeks and im 4 weeks in
im gettin exactly what you say on me leaves . had the prob 4 a while handled it with neem + removing leaves that looked to bad leading to this particular plant being rather naked
. as for the top other than pests i havent got a clue !!
I'm not sure what to advise. The only trouble with burning sulfur is it can give your buds a nasty taste.
but then again, thrips on your buds don't taste too nice either!
Manually remove the adults by gently rubbing the leaves between your fingers and cover the top of the plant pot with white cardboard so it will prevent any eggs from getting to the soil, turning to larvae and completing their life cycle.
To kill them, no-pest strips are good and pyrethirn bug bombs are too. However, only use smoke bombs if you have 3 weeks or more to harvest.
You can get ones that are safer closer to harvest but they are only found at grow shops.
I'm pretty sure this will work with thrips too and apparently is safe to use throughout flowering.

It is true - the bugs taste bitter (so I'm told) under 12/12 so the preds leave off them.
"SB Plant Invigorator" - Works every time. It works by clogginng up the orifices of the mites so that they cannot feed/breathe (forget which). They claim that the spidermite cannot become tolerant, because of this modus operandi.
Whatever, I know I would not be without it in my grow, just in case. I found that three applications halted a small infestation in its tracks and killed them all off. 100%.
