Southern Ag 02901 Liquid Copper Fungicide, 8oz

Southern Ag Liquid Copper Fungicide is a solid, reliable product that delivers exactly what it promises. I used it on a few plants showing early signs of fungal issues, and within a short period the leaves stopped deteriorating and new growth looked much healthier. It’s definitely effective when applied as directed. The mixing instructions are straightforward, and the product spreads evenly with a standard garden sprayer. A little goes a long way, so this 16oz bottle lasts quite a while, making it good value for money. Overall, if you’re dealing with leaf spots, mildew, or other fungal problems, this is a great solution to have on hand. Highly recommend for gardeners who want an easy and dependable way to protect their plants.

> Great for controlling fungus on fruit trees and vegetables, because copper sulfate in small quantities is not toxic to human beings. If your fruit or vegetables absorb a little copper, they are perfectly safe to eat. > It actually needs to touch the surface of the plant that is affected---that is, both the top and bottom sides of leaves, and needs to set there for a while. So, spray from multiple angles, and don't apply unless you expect conditions to be dry for say 6 hours or more. > Can kill or repel snails and slugs, since they are very sensitive to copper. > I mostly spray it on my citrus and mango trees. For some varieties of mangos it is essential in order for the flowers to set (i.e., develop into fruit). I also paint undiluted copper sulfate on tree wounds (e.g., such as those caused by trimming a limb). > It is recommended not to use it on orchids or bromeliads---but I've had no choice when I've treated trees which had orchids and bromeliads growing on them--but the orchids and bromeliads seem to tolerate it with no problem. > Copper sulfate mostly works on the surface of the leaves, kills the surficial fungus, and is washed off with the next rain -- very little is absorbed. Copper sulfate is ineffective against (systemic) fungal infections of the stems or roots, since it is NOT absorbed at significant levels. That means little gets into the fruit or vegetables. > If you have serious fungus problems on non-fruit trees or other ornamentals (such as roses), you may need a systemic fungicide. I use Monterey Agri-Fos Systemic Fungicide 32oz . IS COPPER TOXIC? > Sure, copper is toxic in excessive concentrations. So is virtually every natural chemical element. Salt is sodium chloride (sodium and chlorine), right? --- both of which are VERY toxic. But both sodium and chlorine (both together and separately) are absolutely essential to human health. Copper is also ESSENTIAL to human nutrition --- you can even buy copper supplements on Amzn . The question is the concentration. At the recommended concentrations, copper sulfate is safe to apply and use. At the recommended concentrations, the amount of copper absorbed into fruit and vegetables is negligible. The water pipes in your home are probably copper -- you'll get far higher doses of copper from your drinking water, than you'll ever get from eating tomatoes -- and that copper may be beneficial to your health. > Obviously, it is best to minimize breathing copper sulfate mist for long periods of time, or soaking your bare skin with copper sulfate solution for long periods. It is best to take care disposing of excess copper sulfate solution --- although simple dilution (with more water), or spreading the excess over an area, is probably adequate care. Don't pour directly into a stream. But copper sulfate isn't like an insecticide or systemic fungicide where you need to wear a respirator and rubber gloves to use safely. For household garden use, no special precautions are necessary.

Why did you pick this product vs others?: Price point and review

I live in a rainforest in Hawaii. Used it to spray the outside of my green house that was covered in a green algae. Absolutely killed it all! It has been a couple of months, and the algae has not returned. Note: Applied with my car washing foam cannon....and just filled the foam cannon with the copper fungicide....and it sprayed to the top of the arch....went done both sides, done in 5 min.

This is an excellent antifungal root medicine. I got this for my avocado tree which was getting root rot, it helped bring it back to life and just as the tree was grown, a massive Arizona monsoon and windstorm broke the branches. Now I have a small sampling in it, hoping it will come back to life.

Product: Southern AG Liquid Copper Fungicide Rating: 3/5 (ave) While the product does seem to work, i'm kinda turned off by the fact that when mix up a batch to spray, it rapidly turns from cobalt blue to a fugly charcoal grey, indicating rapid oxidation. I'm switching back to Bonide.

Todo bien

Potente y muy efectivo.
