Copper is a popular broad-spectrum fungicide used to treat a wide range of fungal and bacterial diseases including...

• black spot
• brown rot 
• leaf spot
• black spot
• leaf curl
• shot hole
• bladder plum
• bacterial blast
• mildew

...in roses and other ornamental and flowering plants (that includes houseplants), fruit including citrus, pipfruit, stonefruit and vegetables. Copper is also an essential micronutrient for plants. This is for the 200gm Grosafe FreeFlo Copper which makes up to 50 litres. Measuring cup included.

Why is Grosafe Copper superior to other copper treatments?

Grosafe FreeFlo Copper is an organic copper hydroxide in the form of water-dispersible granules, making it rain-fast and more efficient due to the fine particle size, as well as more bioavailable for better protection from both fungal and bacterial pathogens (pathogens are bacteria, viruses, or other microorganisms that can cause disease). Grosafe's Copper also means less elemental copper for better environmental protection. Certified input for Organics. 

How does it work?

The copper crystals adhere to the leaf surface and continuously release free copper ions, creating a protective barrier that prevents infection. With Grosafe's average particle size a tiny 1.711 microns (compared to copper competitors which average around 7  microns), Grosafe FreeFlo Copper provides better coverage, better staying power as well as making it easier to mix with virtually no dust plus better suspension in water for problem-free prep and spraying.

How to mix and apply Grosafe FreeFlo Copper

Half-fill the spray tank with water. Slowly add the required amount of FreeFlo Copper, stirring well as you go. Top up with water and spray. The measuring cap (included), has marked lines (filled to the top it's equal to 11grams).

Spray to cover foliage well. Can be used by itself, however for best results, use with a compatible spreader such as EcoSpread to reduce beading, increase coverage and ensure better distribution, especially during difficult weather such as hot and dry conditions.

Safety first

Follow best practice when handling or applying this product. The same general safety precautions apply as for any spray treatment, including insecticides and fungicides, even those certified organic or generally safe.

Always check the label before use. Spray outdoors when possible, or in a well-ventilated area. Wear basic protective gear, including gloves and eye protection, when preparing and using the product. A coverall (like disposable Painter’s overalls) is recommended to protect clothing and reduce skin exposure. Avoid inhaling spray / mist. Avoid contact with eyes / skin. Wash hands and exposed skin with soap and water after use. Read the full safety precautions here before use >
