How to Protect Cucumbers from Powdery Mildew: Follow These Rules and You'll Never Know About the Disease
Powdery mildew can most often be found on cucumber beds at the end of summer.
As the expert of the online publication Belnovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh said, most often the attack appears in the greenhouse, but those cucumbers that are grown in the open ground are not insured against it.
You can tell that you have encountered a dangerous disease by the white spots on the underside of the leaves.
Subsequently, the white coating spreads to the leaves and stems, the spots darken, and the affected parts of the plant turn brown and dry out.
Fortunately, there are preventive measures that are almost 100% effective in ensuring that you don’t have to save your crop from powdery mildew.
So, since the pathogen overwinters in the plant remains of cucumbers, pumpkins and squash, try not to plant other pumpkin crops near the greenhouse.
In addition, you should not neglect pre-sowing seed treatment.
Follow crop rotation rules and maintain hygiene in the greenhouse, and do not overdo it with nitrogen fertilizers.
Water the cucumber beds only with warm water and be sure (do you hear me, be sure) to disinfect both the greenhouse and the tools.
As a preventative measure, it is also worth using spraying with biological preparations during the season.
