Perhaps, there are no such gardeners who at least once would not face rotting of cucumbers at themselves on the site. There is even enough observance of special care and conditions of keeping not always that cucumbers have avoided fungal diseases.
In general, cucumbers are plants which are especially subject to fungal diseases. The fact is that cucumbers love high humidity, and in humid environment, as we know, and mushrooms therefore it is absolutely no wonder that this culture often is ill develop. If to contain plants in more arid climate, then it is possible and not to hope for good harvest therefore nothing else remains except how to maintain the necessary air humidity and soils in hotbed and to watch closely saplings, and at emergence of the first signs of emergence of fungus to take measures. Cucumbers are subject to many types of decay, for example, root, radical, gray, white and so on, however in this article we will sort those types because of which first of all fruits suffer. So, vegetables are most often subject to gray and white decay.
Gray decay
The activator of gray decay fungus under the name Botrytis cinerea, develops it because of high air humidity and low temperature condition. The first signs of gray decay is:
- emergence on leaves of gray raid;
- emergence on leaves black krapin;
- termination of formation of ovaries;
- formation of large number of barren flowers;
- rotting of barren flowers;
- death of plants.
If in time to take measures against gray decay, namely to normalize temperature condition (to reduce temperature drops) and to reduce air humidity, then gray decay will recede.
White decay
The reasons of education and this fungus (Sclerotinia sclerotiorum) the high humidity (85-95%) and temperature drops is therefore elimination of these adverse factors - the main step to recovery of saplings. Signs of white decay is:
- softening of fruits of plants and their stalks;
- formation of white spots on leaves and fruits;
- aquosity of escapes;
- termination of formation of ovaries.
For disposal of this fungus it is only not enough to review leaving (airings, fertilizing, removal of sick saplings, etc.), special medicines not to do without processing of plants here. If disease at the initial stage, for processing of saplings it is possible to use folk remedies, for example, whey if the fungus has absorbed the big area of the greenhouse, Rovralya is better to give preference to specialized medicines like Oksikhom, Topaz.
