NEEM Oil Questions

[Glass Man]

Neem oil seems to be a great product around the garden. It is an all natural and nontoxic product which controls Spider Mites and Powdery Mildew, two of our worst enemies (w/o badges that is!!). I've read that there's a penetrating additive which can be used with Neem Oil to help make it even more effective. Also I have been wondering about adding it to the hydro resevoir and/or nute water for potted plants. Does anyone have any knowledge about using it that way?

Also wondering how far into flowering can it be applied? Is it a no-no to use it till the end of flowering, if necessary?

Is it very effective for helping with PM?

What else is it good for?

Does anyone know about Pyrethrin? What all is it good for? Is it as safe (or safer) as Neem?

Thanks,

Neem Oil is a great all natural coumpound derived from the Neem Tree.
Neem oil works great because it not only kills soft bodied insects(SpiderMites)
ect... but messes with the reproductive systems of these insects, causing
inevetible control, eventually.

My feeling on a root zone application is not to waste your money, even if its good. Neem oil is expensive and their are cheaper, better(thinner even!) products out their to take care of damping off and other airborne pathogenic plant sicknesses.(flora sheild(g.h), Hydroguard(natural))

I always make sure i control any infestations before they ever touch a flower
forcing chamber of mine...nuff said on that.

Pyrithium is a plant derived insecticide and is found in most store bought insectisides. It is not nearly as safe and can cause SERIOUS RERSPITORY PROBLEMS!!! This is due to its method of derive from the source and also its intense concentration in store bought form.

For a last alternative try Diatamacious Earth. Its 100 percent mined silica shells(looks like powder). Dust your vegging plants liberaly with a dry application every 7 days to literally rain death on those spider mite f%$^ers!!

Hope this helps....
Good Grow!!!

I used to mix neem oil with enzymes and let it sit for a few days, the enzymes seemed to make it more water soluble and easier to spray in a fine mist

I get my Neem Oil concentrate from Southern Ag. They sell it at wholesale prices in single bottles. They offer it in two sizes 8oz ($5.54) & pints ($9.25). It's a concentrate so you mix 1oz per gallon of water. They sell something called "sticker spreader" which is supposed to make it even more effective. I bought it too, but am a slacker and forgot to add it to the mix. It's even cheaper than the Neem.

S Ag is where I get my cheap commercial hydro nutes. $18 for 25 lbs, makes 30,000 gallons . And they also sell all other brands of plant chemicals too, for better prices than I found on the net.

Oh, btw the Neem bottle says not to store the diluted mix for using later. I think the emulsion, or something, goes bad.

neems is easy to thin out but it still isn't the most soluble.

that's why I mixed it with enzymes, worked really well actually

Dyna Grow has a neem...not too smelly and pretty cheap...

C-Ray, wouldn't enzymes foliar applications by themselves be a tool in the fight against pests and diseases ?
