Dyna-Gro Pure Neem Oil?

[daggazee]

Neem got rid of my daughter's head-lice too. Every kid in her class was infested and none of the expensive potions from the pharmacy worked.

Peace..

it probably would work on lice.... though I wouldn't want to be walking around reeking of stank Chinese food all day...

I haven't had the shiny wax look since using the Pure Neem, with the Einstein it always made them shine... but they are changing the label from spider mite killer, to leaf shine product..... the pure neem had no shine in my experience....

The mode of action is to disrupt the insect's metamorphosis. The principle active ingredient, azadirachtin, acts as an insect growth regulator (IGR) preventing exoskeleton development and impeding the molting process. In other words, azadirachtin prevents the bugs from growing. This is most effective on younger stages of an insects development than when they have reached their adult form.

Neem doesn't kill bugs...

Neem doesn't smother bugs...

Neem is the carrier for azadirachtin the active ingredient that stops bugs from growing old enough to lay eggs. Babies can't have babies...so if you can prevent all the babies from growing old you can eliminate your population.

The oily waxy look some neem oils give to your leaf surface is a by product of the carrier oil neem.

Obviously oil doesn't mix with water...no matter how hard you shake it up. But that is fine...its not the oil that is what matters, its the azadirachtin

Take olive oil for example...you have olive oil, virgin olive oil...then you've got extra virgin olive oil. Why do cooks prefer EVOO? It is the first pressing of the olives that give it a superior taste. This same can be said for einstien oil It's the best...

That was some f'ing awesome explanation, kokua.

It was a very close decision between the Dyna-Gro Pure Neem Oil and the Safer BioNEEM, but I finally went with the Safer brand. The Dyna-Gro was $7.95 for an 8oz concentrate; the Safer was $14.50 for a 16oz concentrate... about the same price per volume (didn't factor in dilution ratio, though...). Let's first hope I don't even have a mite or other pest problem to begin with... but if I do, I hope this does the trick like it did for you DJ Highst!

The mite eradication BioNEEM Team:



Edit: I just peeled back the label, and it lists just about every insect EXCEPT mites... any thoughts on this? Also, the active ingredients is listed as:

Azadirachtin 0.09%
Other ingredients 99.91%

How does that compare to Dyna-Gro Neem? Hmm...

 

[darthvapor]

my dyna gro just says active ingredients 100% neem. I dont rely on just one product. I use the dyna, 3 days later I use the water and soap, 3 days later I use bio-neem, and 4 days after that the last application is sm-90. Thats for treating infestetation already in progress. For just preventing I use neem every month and wash it off 4 days later with sm-90 I usually only apply twice during veg, but I keep my space clean and dissinfect inbetween grows and I got a filter on my fresh air intake.

I am pretty sure Neem oils dont have any active ingredient. They are all 100% neem, but they dont have any Azadachdrin (sp?) as their active ingredient.

If any one want something even stronger try Azatrol (sp?) it is even stronger than Bio-neem, but its over $100 a bottle.

I do neem baths on all my clones and a preventative spray every other week and have no issue with mites.

DJ- azadachdrin comes from neem seeds. I got this from wikipedia
"This compound is found in the seeds of the Neem tree (0.2 to 0.8 percent by weight). Many more compounds, related to Azadirachtin, are present in the seeds as well as in the leaves and the bark of the Neem tree which also show strong biological activities." So its safe to say that neem oil made from cold pressed neem seeds has azadachdrin in it already naturally. It seems to be a secondary metabolite in neem seeds, whatever that means I have no clue

I know Azadachdrin comes from neem.... pretty sure thats been mentioned several times.... cold pressed Neem oils have azadachrin, but like previously mentioned, its not in a chemically active state. Get a bottle of cold pressed neem and a bottle of Bio-neem, pour them each in cups and tell what you think..... they look, smell and act VERY differently.

Find me a bottle of Cold pressed neem that states Azadirachtin as its active ingredeint, take a picture and post it here please. They all list "100% Neem" on the label, but they dont list Azadirachtin as its active ingredient. If you prove me wrong I will happily put a foot in my mouth and give you due props.

What do you think about this ingredient list?

ACTIVE INGREDIENT:
Clarified Hydrophobic Extract
of Neem Oil.................. 70%
INERT INGREDIENTS....... 30%

Also, the instructions and warnings on this bottle are a bit scary... all the other neem / neem concentrate products that I've seen appeared to have more "friendly" labels, but this stuff sounds like it's more harsh to more types of friendly bugs.

 

[DJ_highst_]

thats pretty much the same thing as Bio-neem, they just call it "neem concentrate", whats the consistancy of it like? I beleive that is still different then just the plain "cold pressed seed" versions.


....So I guess this is not quite the same as the Safer brand stuff. I just found some more really good info. I will try to copy it all here. To Be continued....

 

[DJ_highst_]

I have used that stuff too, when I cant find Safer brand Bio-neem.

 

[clowntown]

One thing that bothered me about the Safer Bio-Neem was that it listed every insect EXCEPT mites. I'm not sure why... neem / azadachdrin is just neem / azadachdrin, right? Dunno.

This is all so confusing that I'm thinking of returning this bottle, too, and waiting to see if any mites or other pests show up to begin with...

"Neem seed oil (NSO) is composed of a complex mixture of biologically active compounds. When the natural neem oil is removed from the seeds and treated with alcohol, virtually all of the azadirachtin and realted substances seperate from the oil itself. The remaining oil- without the azadirachtin- is called Clariified Hydroponic Extract of Neem oil. Commercial products containing this extract, such as Trilogy (registered trademark), Triact, (""), Rose Defence, (""), GreenLight, fruit, nut and vegetable sprays do not contain measureable of Azadirachtin and contain an emulsifying agent, so are not pure neem oil and may not be suitable for use on certified organic crops...."

[clowntown]

So this product contains no azadirachtin, which is what I want... correct? In other words, return return return...

 

[dankiestog]

Azatrol is the best hands down..two treatments anythings dead..ands its OMAR so u dont have to panic

 

[DJ_highst_]

from the info that I just found the only products they list with Azadirachtin are: Azatin XL (same as Azatrol XL I beleive), BioNeem, and Ornazin

the neem trees scientific name is: Azadirchta Indica. Thought that was kinda funny

 

[DJ_highst_]

Azatrol is the best hands down..two treatments anythings dead..ands its OMAR so u dont have to panic

I agree, but its over $100 a bottle, but it is also more than twice as strong as Bio-neem. Use this if you already have an outbreak and use the Bio-neem as a preventative.

 

[darthvapor]

I guess your right dj. I just did some research and found this. I guess its good I use both products because they both work well for full coverage. The neem oil is better at powdery mildew and a pest deterrent and the azadachdrin is more of a pesticide but doesnt do much to powdery mildes. check this out

"products containing extracts of neem oil are registered pesticides, tested and approved by the EPA for use as a pesticide. Remember, extracts of of neem have had the ACTIVE COMPOUNDS FOUND IN NEEM OIL REMOVED during the refining process, and these products usually cotain alcohol or phenol used i the extraction process. Theses extracts of neem have an emulsifier added to help it mix readily with water. Pure or "crude" neem seed oil must be mixed with an emulsifying agent to accomplish this. Pure castille soap can be used as an emulsifier when using pure neem seed oil. warm water should be used when using crude neem oil since it becomes soild at room temeratures."
