Description
AEF Global Cyclone Fungicide (Cyclone PLUS) is a bactericide and fungicide used for plant disease management, focused on suppression of powdery mildew and other common diseases. This commercial-use liquid concentrate is a plant disease control product built for growers who want targeted disease suppression without adding extra complexity.
Cyclone Fungicide is made with citric acid and lactic acid as the active ingredients. It is positioned for suppression of powdery mildew across a range of horticultural crops, including greenhouse cucumbers and field cucurbits such as cucumbers, squashes, and pumpkins. It is also listed for powdery mildew in grapes, plus greenhouse and outdoor ornamentals including cut flowers.
Beyond powdery mildew, Cyclone Fungicide is listed for bacterial canker in tomatoes, and for black spot on greenhouse and outdoor roses. It also covers fire blight on apples, and it is listed for control of anthracnose fruit rot on blueberries. If your priority is reducing disease pressure that can compromise foliage, flowers, or fruit quality, these targeted disease claims are the core reason growers keep Cyclone in their disease program.
Cyclone Fungicide is suitable for foliar application and is presented for both greenhouse and outdoor production settings where diseases like powdery mildew and leaf-spotting problems can show up quickly. It’s a good fit for commercial growers and serious gardeners looking for a single bactericide and fungicide option that focuses on powdery mildew suppression while also addressing bacterial canker, black spot, fire blight, and anthracnose fruit rot where those problems are part of the crop cycle.
Citric acid helps improve nutrient availability by gently lowering pH and binding certain minerals so they stay more usable for roots, which can reduce common lockout symptoms like pale new growth. It’s unique because it influences nutrient behavior beyond pH alone, making it especially helpful when nutrients are present but not being absorbed efficiently.
Why is lactic acid important for plant fungal control, and what makes it unique compared to other options?
Lactic acid is important because it helps make the leaf surface less friendly for fungal spores by temporarily lowering surface pH, which can reduce early spread during humid conditions. It’s unique because it works mainly by changing surface conditions rather than feeding the plant, adding living microbes, or relying on a highly targeted chemical mode of action.
