Interesting facts about the development of late blight on tomatoes in the greenhouse

0

When growing tomatoes, the risk of late blight is always high. Almost no season goes by without this disease attacking tomato plantings. The appearance of late blight can destroy the crop, so understanding the factors of its appearance will make it possible to reduce the possibility of its occurrence.

Why it appears

The development of late blight on tomatoes is facilitated not only by weather conditions. The risk increases significantly if potatoes grow nearby. They can get sick together. Among the negative factors, frequent rains and plants that are not adapted to the influence of external factors should also be noted.

Pay attention to the soil. Everyone is trying to improve it, nourish it, but not everything is so simple. Land that is very generously filled with organic matter has an excess of nitrogen, also a negative factor. Phytophthora will appear much faster on such soil.

There is also a question about the arrangement of the greenhouse. It is a mistake when the side walls of the greenhouses are made of glass, and the roof is made of film. It is better to do the opposite. In greenhouses with a film roof, Phytophthora appears much faster. Studies show that in film conditions the disease makes itself felt 2 weeks earlier.
