My little indoor garden got spider-mites. OMG! I tried Dr. Doom 2 or 3 times. I tried predatory mites.
Every time the little &$*#%^ came back. Somewhere I read that this was good for getting rid of them. Although I was skeptical, nothing else seemed to work.

I used SM-90 according to directions for a foliar spray (5 parts water to 1 part SM-90) and sprayed the plants well including the undersides of leaves. Next day I went over the plants with q-tips and removed all the spider-mite webs.
5 days after spraying didn't see any sign of mites but I sprayed again just in case they were hiding. It's been over 6 weeks and I have not seen a mite under any leaves and no webs anywhere.

I like it SO well I went and bought a gallon! :-)

I am extremely pleased with this product.

This can be used for systemic (root feeding) to prevent problems, and can also be used as a foliar spray to stop a bug attack in it's tracks.

The main ingredient is Coriander oil. It has a little smell which doesn't bother me, but some dislike. It is food safe.

Can be used in both the vegetative stage and in the bloom stage. I was able to save a crop that was only 2 days from harvest, using this as a spray directly on the leaves, flowers, and fruit. Add a little TLC and wash or wipe each leaf of your plant as lovingly as you have time for. I also rinse with water by foliar spray.

Always remember to pH your water after mixing SM-90. Depending on your application, the pH will NEED to be between 5.5 and 7.0. Remember, a little goes a long way, so mix according to directions, then pH.

SM-90 not only protects against spider mites, aphids, and a host of other bugs, this also kills and prevents white powdery mildew! Any place you have treated on the plant, will Not get WPM again! Just don't forget to treat new growth over time.

This is the product you Need to have at the ready so when a problem arises you can treat right now.

Happy gardening!

Use as directed, this is really good stuff. I'm not sure about the bad reviews because this product took care of wpm, mites and even rust for us. I was freaking out because I don't want to use poison , so this fit the bill. It works more by suffocating the mites. Cropsaver.

I guess its good to my green leaf plants who got attacked by some kind of a green worm leaf eater.
this nasty little thing gets in the leafs and makes like a "wrap" from treads similar to cobwebs.
Briefly, Im not sure how effective this is but, when I spray my plants the green worm doesn't show for a couple of days. Once the oil gets washed off the leaves the plants get attacked again.
I am confident that the product isn't toxic in any way it is simply coriander oil!

SM-90 is a food safe insecticide and root conditioner. It kills fungus, and all sorts of other pests. Works very well on powdery mildew. This is a very good product. It has saved my plants from many pesky pests.

Love this stuff. This bottle was full and not opened like the previous bottle. A bit pricy as a spray but in the Rez or a half strength spray for use as a sticking agent it's the best. Smells great too.
