A gardener must regularly inspect garden crops to promptly detect signs of dangerous diseases.
Thus, a bad sign is the appearance of a large number of spots on the cucumber leaf blades. These spots can be white or brownish.
Such characteristics often indicate that the plant has encountered a dangerous disease - powdery mildew.
If you ignore the problem, you can completely lose your harvest.
How to prevent illness
To protect the crop from disease, you need to choose the right place to plant the plant.
So, cucumbers should not be planted in the same bed where the plant was already located last season or the season before.
It is not allowed for the garden crop to encounter low temperatures. To do this, it is necessary to maintain a temperature of at least +23 degrees in the greenhouse. You should also avoid watering cucumbers with cold water.
Fertilizers should be applied carefully. Excess nitrogen can cause powdery mildew.
How to deal with a disease that has already manifested itself
What should you do if you were unable to protect your cucumbers from the disease?
Then the plant needs "first aid". We are talking about spraying with a certain agent.
It is very easy to prepare. You need to take a bucket, fill it with water (the liquid should not be cold) and add 2 milliliters of the preparation called "Topaz" to the container.
After thorough mixing, you will have a solution that should be poured into a spray bottle.
It is advisable to spray cucumbers at a time when there is no rain or strong wind.
