With the arrival of heat, the plants in our green space are more exposed to the attack of fungal diseases which affect both vegetables and ornamental plants. In this regard, let's see how to eradicate fungal diseases effectively and harmless to the environment.
How to eradicate fungal diseases, prevention
Among the fungal diseases that most affect vegetables, shrubs and ornamental plants, we find powdery mildew, a disease that presents itself with whitish spots on the green parts: the leaves turn yellow and dry, and a downy-looking mold forms. The appearance of this fungus is facilitated by humid conditions, with both low and high temperatures.
To prevent powdery mildew from occurring, it is essential:
- do not get the leaves wet when watering

- do not water in the evening to avoid water stagnation on the leaves.
