What to do to avoid having to fight downy mildew: effective prevention of downy mildew
Most often, plants affected by downy mildew can be found in greenhouses or under films.
As the expert of the online publication Belnovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh explained, this is explained by the fact that for the reproduction of spores of the fungal disease, high humidity and a temperature of 15 to 25 degrees are required.
Downy mildew can affect cultivated crops when there are already three leaves and does not reduce its activity until the end of the growing season.
If you are determined to prevent downy mildew from appearing in your garden, you should disinfect the soil after signs of the disease have been detected.
Even better if you have the opportunity to change it completely.
In addition, try to reduce humidity to 80% to stop the development of the disease.
In the fight against downy mildew, a procedure such as spraying plants with a 0.4% solution of copper oxychloride and cuprosan has proven itself to be effective.
You can also use 1% Bordeaux mixture with barium chloride - it is added in a 1 to 1 ratio with copper sulfate.
