July is exactly the time when cucumbers can look healthy still yesterday, and today already become covered with spots. First small yellow or brown dots appear on the leaves, then they increase, the leaves dry, and the plant starts to lose strength. If nothing is done, the harvest quickly decreases.

To prevent the development of brown spot, rust and powdery mildew, it is worth regularly carrying out preventive treatments. One of the proven homemade solutions helps create an unfavourable environment on the leaves for the development of fungal diseases.

Recipe of the mixture:

• 1 liter of whey or low-fat milk;
• 9 liters of clean water;
• 10–15 drops of pharmaceutical iodine.

Mix everything well and use immediately.

Spray not only the upper side of the leaves, but also the lower, because exactly there fungal infections most often start to develop. It is best to carry out the treatment in the evening or in cloudy windless weather, when the sun is no longer burning the leaves.

For prevention it is enough to repeat the procedure once every 7–10 days. If the first signs of the disease have already appeared, the interval can be reduced to 4–5 days.

But even the best solution will not help if the bed is thickened. Cucumbers need free air movement. Regularly remove old lower leaves, do not water the plants on the leaves in the evening and do not allow prolonged stagnation of moisture.

Remember: it is much easier not to allow the development of the disease than later try to save the vines that have already lost most of the leaves. A few minutes of prevention every week often mean many more weeks of generous collection of juicy, crunchy cucumbers.
