Between harmful insects and pests (aphids, beetles, slugs, etc.) and cryptogamic diseases (alternariosis, peach blight, powdery mildew, etc.), our vegetable plants and other fruit trees can suffer great damage. Among gardeners, however, it is often mildew that is the most well-known and feared. If nothing is done to stop the infestation, the fungus can quickly spread to all parts of the plants. It is necessary to remove all infected plants from the garden or vegetable garden to prevent it from spreading further. So many crops are lost because of these spores that cause black and brown spots on leaves and fruits! To eradicate this destructive cryptogamic disease, there is no need to use chemical phytosanitary products. Here is a grandmother’s recipe against mildew that you must know.
With this natural remedy that uses essential oils, you will avoid using Bordeaux mixture, whose copper can pollute the soil.
