Powdery Mildew is a frequent problem in the growroom. While this fungus won’t (as is often said) destroy your crop there’s nothing you can do but prevent it. Copper Fungicide is by far the best preventative product available to growers using Hydro as a growing medium. The reason for this is simple, Chemical funticide like captan and thiram do not work when mixed with Hydroponic solutions. Copper based fungicides are however an exception to this rule as Copper being an element does not alter its molecular structure in a hydro solution meaning it remains chemically active thus preventing infection. For Powdery Mildew prevention the best solution is an application of copper fungicide at 2-3 weekly intervals during your plants flowering cycle. It should be noted that Powdery Mildew can live on seeds and or clones of infected plants so make sure you sanitise all your equipment after any spray application. Copper fungicide for powdery mildew is a traditional way to control this disease. Copper fungicides appear to be less affected by previously applied fungicides. Copper fungicides act by attacking fungal cell membranes. Copper-based products are not used on grapes. Copper sulfate is classified as an extremely hazardous substance due to its toxicity and its potential to cause oxygen depletion in water. Copper fungicide is an effective method of control for preventing powdery mildew. Powdery mildew is the term used to describe a number of fungal infections that can cause leaf damage on a range of indoor and outdoor plants. Copper fungicide is likely to be a popular choice due to its effectiveness when dealing with powdery mildew and its ability to retain efficacy over a long period of time. Copper fungicide can be applied by garden and landscape maintenance professionals or DIY enthusiasts, as it is safe and easy to use, adhering to most plants.

How Does Copper Help Plants

Copper is a micronutrient that is essential for plant growth. It helps plants grow by helping them convert nitrogen from the air into proteins, which are needed to make chlorophyll and other pigments that are involved in photosynthesis. Copper also plays an important role in enzyme production, which is critical to a plant’s ability to produce energy through respiration.
