Monterey (LG3190) - Liqui-Cop Copper Fungicidal Garden Spray, Ready to Spray Liquid Copper Fungicide for Disease Prevention in Plants (32 oz.)

Good stuff. Saved my little pine trees from dying from some type of brown needle disease…

This product works very well, and it is very easy to use.

I really like this product. It attaches to your water hose and it’s very easy to use when spraying your plants. I have use the product three times now on my eunyomous shrubs. The powdery mildew is gone and the shrubs are healthier than ever! Will definitely buy again.

I bought a house in summer 2021. The property has a dogwood tree. Previous owner told me it was sick with “anthracnose” and left behind a substance to treat it with.Fast forward a couple of years and I didn’t find the treatment effective, so I searched on Amazon for something new and found this product. Decided to give it a try.The previous owner advised me to treat it after the first flowering stage and then in late September. So I did: I treated it for the first time late September 2023. I then treated it after all the flowers had fallen in late spring of this year, 2024.The results so far have been jarringly good. This year the leaves grew in with a lush, healthy-looking spring-green hue. Even my neighbors noticed & complimented me on how great the tree looks this year. The bark also seems “earthier.”I’m not a botanist or anything so I can’t really speak to if this treatment is actually fighting the disease or simply treating the symptoms. Regardless, I went from worrying about possibly having the tree taken down to feeling a lot better about it lasting another decade or so.The product attaches to a hose and when activated sprays a blue-ish liquid. Pretty easy to use. Not much more to say, it helped me and I recommend it!

The chemical itself does what it’s supposed to do and helps control fungus on my peach trees. I’ve bought it multiple times because of this. But there is a special place in hell for whoever designed the on/off wheel. I have to cut the plastic tab completely off just to be able to get it to work and then it’s still super hard to turn.

I loved this product it is great to use on anything that requires it. I don't attach a hose to it and use it. I cut it open pour some if it into a spray bottle and then spray my plants. Only use during the dormant season. If used when plants have leaves it CAN prevent photosynthesis from occurring. I like to spray it twice before buds start appearing. Great product, I'll definitely buy again when I run out.

Working great on my peach tree

As others have also commented, the container I received had substantial leakage as shown in attached photo. Be VERY CAREFUL where you open the package, since the material can stain surfaces.
