Tell me, please, what is this with beets and what can be cured? And many more rotten leaves

Answers:

Signs of beetroot aschitosis Lower, old leaves are covered first with blue-green spots, which subsequently become necrotic brown foci of sporulation. In the center of the brown spot there are many dark points - this is the concentration of pathogens. Following the leaves, the fungus affects peduncles, seed plants, and even root crops. For one vegetative period of beets, the fungus can give several tens of generations. Damaged tops quickly die off, because of this the development of the vegetable stops, and the yield of the plot falls by at least 15-17%. And ascochitosis and peronosporosis can be eliminated only with the help of fungicides. In addition, it is very important to observe the correct fertilizer system. It is necessary to form it taking into account the needs of the soil and the vegetable itself. Doses of fertilizing should not only be balanced, but also justified by the urgent need for root crops. Signs of cercosporosis: a fungal pathogen and its treatment with beet cercosporosis is called the spotting of the leaf plate that the pathogenic fungus causes. Every year, this disease deprives many summer residents of their legitimate harvest, because it develops very quickly and aggressively. In the vegetable itself, this disease manifests itself under the guise of numerous round and oval spots with a gray-brown hue. The spot has a characteristic brown necrotic border. The diameter of the fungal infection is up to 6 mm. Over time, the necrotic parts merge and the entire leaf is affected. The shrunken fabric falls away. If urgent measures are not taken, the pathogen fungus will very quickly move from the focal form of existence to the occupation of the entire plot. With such active reproduction, there is a great risk of the death of the entire green tops. Measures to combat beet cercosperosis include the following: Preventive treatment of beet allotments with Rex Duo and Abacus preparations. The consumption rate for preventive measures is 0.7 liters per hectare. Urgent use of fungicides such as Abacus, Rex and Tango. Which are characterized by high antifungal effectiveness. And also have the longest period of protection, up to the harvest. This method is most effective in the early detection of infected plants; Collection and burning of infected plants. All manipulations on the disposal of spore-bearing parts are best carried out outside their area, which will help to avoid the spread of the fungus by air.
