## Description

Southern Ag - Liquid Copper Fungicide - Fungicide, 16oz

Review: Effective and Easy to Use – Great Results! - 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.
Review: > DOES THE JOB - > 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.

## Questions & Answers

**Q: Why are all the reviews for different items??? Boxers, nailpolish, shoes, mugs but no fungicide. I smell a scam cooking!!**
A: I have seen reviews for the wrong products sometimes. I suspect a data error. Funny thing. I did not order this product. I think some Amazon folks are overloaded.

**Q: will it work for palm trees ?**
A: It is a prescribed treatment for queen palms after cold weather has damaged the phytophthora causing the center bud to rot. Remove the rotted bud (spike) and treat the center of the tree only. Refer to guidelines specifically for palm trees for proper mixture.

**Q: Can this product be used to control dothistroma needle blight on austrian pine and is so what rate should be used (teaspoons per gallon)**
A: label says it treats blight . And yes  I would only use a tsp. to a gallon ratio, at least this is what world on my ornamental crab trees. good luck

**Q: Will this product help with lilac blight? thanks**
A: Yes, it will but you need to prune the infected branches and twigs first if they are noticeable.  Also rack around the base of your brush and clean up old leaves and debris.  The blight thrives in moisture and the lilac brush probably leaves more air circulation.  Cleaning up helps this.  Spray with a solution mixed according to directions in the fall.  In the spring, spray before bud formation if you can.  If it has already bloomed, go ahead and spray and repeat in two weeks.  Hope this helps.  I do love the old-time lilac's.
