Review: Works as intended - Works as intended, have purchased this many times, and will again.
Review: If You're A Beginner, Hire Someone - This works like a charm for me. Then again I, like another reviewer, follow ALL instructions. I use a cheapo pump sprayer too, so if this product was going to damage any tools it'd definitely be the one I got. I use this twice a year, sometimes once every couple months if necessary, on many kinds of plants from wild roses to fruit trees to bell peppers. It keeps the pests off, the beneficial bugs safe, its cured black spot and mold, and I don't have to worry about my dog or the neighborhood strays getting sick. It would be a shame for this product to disappear over user error. And yes, it stinks. Its not perfume, its a 3-In-1 chemical spray, so I don't know what some people are expecting here. And yes, you should wear gloves, which anyone would know if they actually read the directions. Or had any common sense about chemical products that KILL certain types of organic life. If you can't follow directions and common sense, then I guess we just have to live with your contribution to soil pollution and cancer when you go grab a bottle of Roundup. Or maybe just hire someone if you don't know what you're doing. Sorry for the tone of this review, I'm just so over ineptitude causing products I love to get canned.

### ⭐⭐⭐⭐ Be careful, don’t overuse
*by C***E on December 16, 2025*

Works fine, just be careful not to overdo it, it is a concentrate so it must be diluted. If you overdo it, it will cause rot, black spots, & just straight up kill whatever plant you spray it on. If you use it & your plants start to turn brown & die, wash it off immediately with Castile soap.
