Powdery mildew on cucumbers. Who is to blame and what to do to save the harvest - my safe way
It's a shame when the cucumbers grown with care, are suddenly struck mildew. Confuse it with other diseases complicated by plants: the leaves appear white spots. It seems that someone is planting vegetable powder with flour, which is why the diagnosis is well named.
In fact, the white portions - of the fungus colony is slowly destroying cucumber. Harmful microorganisms rapidly reproduce by spores, ready to attack. So do not ignore the problem.
Where does the fungus
To the "stars" came together and planting mildew sick enough influence 3 factors:
- The presence of the causative agent - the fungus spores. Is immune from this, no gardener. One need only consider that the risk of powdery mildew above on the beds, where the fungus has raged in the past year. Therefore, in the fall, after the harvest of cucumber, land treated with potent fungicides.
- High soil moisture. Rainy summer, abundant watering - all this creates a fertile environment for active growth of various fungi.
- Cool weather.
Indirectly to causes powdery mildew include a lack of nutrients, negligent care, poor ventilation beds or greenhouses.
But! In such weather, as it is now in the suburbs, for example, powdery mildew is not insured even the most attentive grower.
How to get rid of mildew with cucumbers now, in the height of summer
Grower could go for the most simple way. Generously fill the bed of cucumber strong fungicide couple of times. If it were not for one "but": after harvest chemicals are allowed to be collected through 20-70 days after treatment, and cucumbers grow now.
Safe choice - Chemical fertilizers. Forgive me, fans of folk remedies, but "Grandma's recipes" have not justified my confidence and often difficult to use. It is much easier to buy biofungtsid designed specifically to combat pathogenic fungi.
My favorite times proven to be effective - "fitosporin-M". This bacteria that are not harmful to humans and plants, but the mildew suppress "Hurray." "Fitosporin-M" can be applied at all stages of cucumber growth, for the prevention and treatment of fungal diseases.
