The best protection against diseases and insects in plants is preventive measures. Treat the same country and garden crops should be at the first signs of the formation of problems. Viral diseases manifest themselves in the form of changes in colors and shapes of various elements of the plant - flowers or leaves. You can save plants from infection by burning the source of the virus. Fungal diseases are formed due to non-observance of hygienic conditions during planting or agricultural work. Bacterial diseases in plants are very rare, but the harm can be very great, and the consequences are serious
Septoria is a problem that results in the formation of light red spots that rapidly spread over the surface of the leaves. As a result, the leaf plates dry out completely. You can observe a similar disease on asters, snapdragons, nasturtiums or tobacco. Immediately upon observing signs of a violation of the plant species, it is necessary to treat the flowers with a solution of Bordeaux liquid (1%) or copper oxychloride (0.5%). As a preventive measure, the seeds should be treated with potassium permanganate before planting.
Powdery mildew is presented as a white bloom observed on the green ground mass of the plant. The fungus multiplies very quickly and mercilessly at temperatures above nineteen degrees Celsius. Also contributes to their reproduction and excessive moisture. Powdery mildew is observed on a variety of plants, the list of which includes roses, dahlias, poppies, violets. The disease can be cured by pollination of plants with a mixture (copper sulfate + laundry soap + soda ash) in an amount of fifty grams, dissolved in ten liters of water. Sulfur powder, zineb, or basezol are other effective remedies.
Botrytis (gray rot) looks like a grayish bloom with a fluffy texture. You can observe it on peonies, hyacinths, tulips, irises and other flowers. The disease develops in warm, humid weather. Also, the reason may be a lack of calcium and phosphorus in the soil. You can destroy pathogenic bacteria by treating plants with a solution of Bordeaux liquid. Boric acid and copper oxychloride solution (0.5%) are suitable as a means. In this case, the damaged root system must be destroyed. Dry the bulbs thoroughly before storing.
Plant rust is an infectious disease caused by puncture of a fungus on a culture. Leaf plates acquire brown or brown spots, transforming over time into voids. All bulbous plants are at risk of being damaged by this disease. Cultures can be cured with a copper chloride solution. Plants are treated with this agent only during the growing season. Until the buds open, you can use iron sulfate. In no case should Bordeaux liquid and sulfur be used in this case.
Leaf curl is usually formed on phlox. But other plants are not always protected from the formation of a similar problem. You can distinguish the disease by the tightened veins. It is from them that the leaves subsequently curl up and acquire a yellow color. It is difficult to deal with this violation. For this reason, these plants are best simply destroyed. Jaundice manifests itself in the form of crushing leaves and the formation of yellowness. Asters are most often affected by this problem. Here it is also more correct to simply destroy the specimens of flowers.
Penicillus rot is characterized by a spore-shaped reddish-brown spot. A disease is formed due to improper storage and excessively early digging of the bulbs. The development of the disease can be prevented by examining the inoculum. The bulbs must be absolutely free from damage. It is important to create optimal temperature readings during the entire storage of flowers.
White spot is a disease that can lead to a dangerous consequence - the death of all leaf plates. The problem can be identified by the first sign in the form of round brownish specks. You can try to cure the plant with a solution of Bordeaux liquid (1%). With its help, it is necessary to pollinate crops for exactly two months every ten to fifteen days.
