Spider-mite CURE!!!!

March 30, 2014

Size: 1 literVerified Purchase

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! :-)

This is a fantastic solution to the spider mite or aphid problem for any gardener!

December 2, 2013

Size: 1 literVerified Purchase

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!

Should have on hand.

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.

Great stuff but too expensive see details

Size: 4 literVerified Purchase

With the usage rates as high as they are, this stuff gets kinda spendy if you use it as suggested on bottle. For instance I use it foliage spray, it’s roughly 250ml per quart, which means the gallon of this stuff will make 16 applications. That’s about $5 per application. “OK” but this stuff used to be $50 per gallon. What gives? I can’t justify buying it anymore. Anything over 60$ and you lost my interest. It’s nice stuff but I will be looking for a different we it’s nice stuff but I will be looking for different wetting agent to use

A great product for spider mites

September 20, 2017

Size: 1 literVerified Purchase

A great product for spider mites, fungus gnats, thrips, botrytis, rooting clones, and helping to make establish plants flourish. So many uses for this amazing coriander oil based product. Do a little research online to see just how amazing this product is. Due to legal reasons they cannot claim it helps with any of these issues, but I have been using it for over a decade with awesome results.

Swear by this stuff it's like a gift from God himself so to speak. Works as intended and so many other benefits from using this product. Keep a few bottles of it on hand in case a friend has troubles I can introduce them to something that actually works.

Not bad at all

Had spider mites, and it helped with other ingredients used to kill them and control them. Not bad at all. Just have to be persistent with it.
