Various plant diseases often develop in greenhouses, since crop rotation is not observed and the same crops have to be grown.
Among the most dangerous diseases, the expert of the online publication BelNovosti, agronomist, landscape designer Anastasia Kovrizhnykh named late blight.
The disease manifests itself in the form of dark watery spots on the leaves and stems of plants, which then increase in size and can lead to the death of the plant.
Perhaps the most important step you can take in the fight against late blight is to prevent it from appearing in your greenhouse.
The risk is especially high in cold and rainy weather, which typically occurs in the second half of summer.
A sign of the approach of the disease are separate foci, spots of late blight on potato leaves. If you notice such a phenomenon in potato beds, be sure to treat the greenhouse plants.
For this you will need biological agents.
If late blight has already attacked the plants in the greenhouse, biological preparations will be powerless. As "heavy artillery", use compositions containing copper.
