Phytophthora is a real headache for gardeners.
Moreover, it can be quite difficult to fight it.
Agronomist Anastasia Kovrizhnykh suggested how to get rid of late blight in a greenhouse.
Reasons for the appearance
Greenhouse conditions can be favorable for the development of this disease that affects tomatoes.
In particular, increased temperatures and high humidity can lead to its development.
Other factors can also influence the appearance of late blight.
This could be due to excessive watering, excess nitrogen, or, conversely, a lack of certain microelements.
This disease can develop if there are potato beds growing near the greenhouse, or if the plantings are very dense.
How to fight
Before planting tomatoes in a greenhouse, the soil must be treated. For this, you can use a solution of phytosporin.
This remedy will help destroy the fungus if it has survived in the soil.
When planting seedlings, you can put glyocladin tablets in the hole.
One tablet of this product is enough for one hole. It will also help prevent the appearance of root rot.
In addition, it is worth monitoring the humidity level in the greenhouse. It needs to be regularly ventilated.
When the tomatoes get a little stronger and grow a little, they can be watered with a solution of wood ash. This will also act as a fertilizer.
It is important to pay attention to the soil after harvesting. At the end of the season, a solution of phytosporin can be added to the soil again.
