One of the common diseases that summer residents have to protect cucumbers from in the greenhouse is powdery mildew.
The first sign of damage is blackening and curling leaves, as well as falling fruits. Here is the simplest way to protect plants from this scourge.
As the ancient wisdom says, any disease is easier to prevent than to treat. And in advanced cases, it is difficult or even impossible to overcome powdery mildew.
Therefore, it makes sense to take preventive measures.
How to proceed
To definitely destroy fungal spores, you need to use fungicides containing sulfur. These can be "Topaz" or "Privent", "Sulfarid" or "Bayleton", etc.
If the crop is already bearing fruit, it is better to use Fitosporin, Fitodoctor or Baktofit.
Prevention
1. The main rule is to follow the watering regime, regularly and without flooding the beds.
2. The air temperature in the greenhouse should be kept within 23-25 degrees Celsius.
3. It is necessary to apply fertilizers correctly and in a timely manner and carry out disinfection before planting plants, as well as observe crop rotation.
4. It is important to maintain a distance between plants when planting – at least 60 cm.
5. Do not forget to regularly ventilate the greenhouse, and also choose crops that are resistant to this type of disease.
