This stuff is the bomb! I've been using it on my roses, coneflower, gayfeather, and tomato plants with great success.

"The effectiveness of Neem Oil is based on several modes of action. It disrupts insects' hormonal balance so they die before they molt to the next life stage. Neem Oil suppresses some insects' desire to feed and also repels in areas that have been sprayed.
Dyna-Gro 100% Pure Neem Oil

These different modes of action result in broad spectrum control of the majority of insects that harm your yard and garden. Neem Oil spares many beneficial insects such as honey bees and lady bugs that prey on undesirable insects. Without beneficial insects to control pest populations, plants are even more vulnerable to new infestations.

Neem-based products have been extensively tested and used as effective insecticides in commercial greenhouses. The Neem seed has been the subject of extensive testing throughout the world since World War II. Neem has been tested at major universities throughout the U.S. since 1982. Pure Neem Oil is completely organic and is not diluted with other ingredients. It comes from the neem tree, a renewable resource. The neem tree is native to India, Africa and several other tropical countries. You can learn more about Neem Oil at The Neem Foundation.

and from https://www.weekendgardener.net/plant...oil-060806.htm

"we have talked about how great neem oil is as an insecticide and mitacide, but we don't want to forget the many fungal and bacterial problems neem oil can also solve.

Neem oil is pressed from the fruits and seeds of Neem (Azadirachta indica), an evergreen tree which is native to India, and is used as a broad spectrum insecticide, miticide, and fungicide, which is used on vegetables, fruit trees, ornamentals, and more.

It is used commonly as an effective fungicide for the prevention and control of various fungal diseases including:

* powdery mildew
* black spot
* mildew and scab
* anthracnose
* rust
* leaf spot
* botrytis
* needle rust
* tip blight
* alternaria

It also controls bacterial diseases such as fire blight.

As a preventative: neem oil should be applied on a 7 to 14 day schedule until the potential for disease development is no longer present.

To control disease already present: apply neem oil on a 7 day schedule until disease pressure is eliminated. Then continue spraying on a 14 day schedule to prevent the disease from reoccurring."

Neem Oil is quite great stuff I agree. Thanks for the info on the neem seed meal. I am going to find a source for it soon.

Picked up some Neem seed meal yesterday at the shop for my outdoor ladies.

Lets see if it will get off those "spit bugs"

[maryjohn]

I use it every week to keep problems at bay

[Joey56789]

So I got a Kentucky Colonel (spearmint) seedling from a nursery. I've seen some bug damage, and now some silk/cobweb like stuff, that I think are spider mites. I hit it with Neem oil foliar spray. Since it is next to my sweet basil and chives, I'm just going to hit those too (and probably the cilantro and thyme and habanero... sigh...). How long do I have to wait before I can go back to eating my herbs? Neem flavored Mojitos don't sound that good, though I do kind of like how it smells.

I use neem oil but recently found out about GH Azamax.

Bought a 4 oz. bottle so we'll see what that's like.

Neem oil with dial soap works good though, I just like Azamax's more simple application and the fact that it's advertised to be safe to use up to and on the day of harvest.

I use neem oil at 5ml with dial soap at 5ml in 24 oz. RO'd water, definitely works to kill/reduce pests (in my case whiteflies and some type of flying bugs).

thanks for the info about the other problems neem oil battles for us barnyard. good to know about the seed meal Clackamas Coot. gotta get some. after finding neem oil I had been problem free for 2 years, till now.

used it for mites my first grow and just kept using for the next 3 grows after it had killed off the mites for me. forgot to use it this grow for some reason and I have mites again. AND powdery mildew and rust spots for the first time. after some treatment things are getting back to normal again. hate setbacks. the neem musta been fighting off the other ailments and I didn't even know it.

neem oil is a great tool to fight off problems after the fact, but it's also a great preventative measure too. ya just gotta remember to use it. lol.

i never really was a big fan of neem oil, i had a bad mite infestation once and the neem didnt work! emptied a whole bottle and the bastards still spun some mean webs! i like sm90 or sm190 its a leaf wash that not only controls the spider mites but it kills them!
