Grosafe FreeFlo Copper - Broad-spectrum fungicide for black spot, mildew, leaf spot - 100gm
Copper is a popular broad-spectrum fungicide used to treat a wide range of fungal and bacterial diseases including black spot, downy mildew and leaf spot. Copper is also a micronutrient essential for plants.
This is for the 100gm Grosafe FreeFlo Copper granules, 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).
For Roses and ornamentals, to treat diseases such as black spot, leaf spot and mildew, use at the rate of 20 grams per 10 litres.
Apply at bud burst on flowering plants, and green tip (around September), leaf fall (around May), and during winter dormancy.
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.
