Used Crossbow brush killer & within 48 hours the brush was dying.
Great stuff!

Prompt delivery. Good price. Works well.

My order was correctly and quickly executed.

I began using MSO last year when a new herbicide recommended only using MSO. The MES-100 from Keystone was fairly priced and shipped quickly. This stuff makes your herbicide as deadly as it can possibly be. At first I was not happy to see the MSO recommendation on my herbicide label because I have always used my own cheap dish soap. But after finding MES-100 at Keystone, and seeing the results, I am glad that I had to use MSO with the herbicide that I was using on Texas Mesquite and other mixed brush.

I first used this product in Placerville CA, as this is a place for heavy poison oak/ sumac and I am highly allergic. It was great for that so I thought I would try it on the tomato weeds ( woody stems with thorns and they reproduce from root and seed) in Silver City NM. So far so good. Within 12 hours they are showing signs of wilting!!! And, it is taking out the other crazy weeds here. Thanks

This works good when the weeds are small - a second application is needed when they are bigger then 6" or so. Will continue to use.
