The same high humidity that most orchids need for optimal growth can also leave moisture on leaves, which encourages disease. Providing good air circulation around orchids keeps foliage dry and diseases at bay. But if a fungal disease does attack your plants, you need to use a fungicide to nurse them back to health. Before you reach for synthetic chemical fungicides, consider reaching inside your spice cabinet for the best organic remedy — cinnamon.
Orchid Fungal Diseases
Orchids are particularly susceptible to black rot fungal diseases from Pythium and Phytophthora fungi. These pathogens cause leaves to turn black before they die. Diseases progress rapidly and can kill plants unless you treat them with a fungicide in their early stages. Anthracnose (Glomerella and Colletotrichum spp.) moves from leaf tips to bases, turning leaves brown as the infection rots tissue. When Cercospora leaf spot (Cercospora spp.) infects plants, it causes chlorotic leaves, which turn yellow and bear dark spots that enlarge as the disease worsens.
For fungicides to manage a disease, you must begin treatment in its early stages. You may also use them as a preventive measure before diseases takes hold of plants. Many synthetic chemicals are available commercially for orchid diseases, but the American Orchid Society recommends powdered cinnamon as an excellent fungicide. Not only does it kill fungal pathogens, but it is also a safer alternative than synthetic chemicals around children and pets. The U.S. Environmental Protection Agency lists cinnamon as a minimum-risk pesticide, which means that its use has been demonstrated as safe’
If your orchid is infected with a fungus, you must first remove diseased parts before you apply fungicides. Apply ground cinnamon to exposed areas where you removed infected leaves, shoots or roots. You should also treat the surrounding tissue by first wetting dry areas so that the cinnamon adheres. The American Orchid Society suggests mixing cinnamon in oil or casein-based glue to make a thick paste before applying it over wounds and surrounding tissues. This holds the cinnamon next to the wounded surface and creates a waterproof barrier against pathogens. source
