Ways to protect floral plants from various forms of rot
Decontamination of soil with fungicidal preparations.
Treatment of bulbs and tubers before storage for storage with various copper-containing preparations.
Careful observance of storage conditions for planting material.
Disinfection of tubers and bulbs before planting with homo.
Screening of diseased bulbs and tubers.
Before planting bulbs, it is recommended to pour wood ash into the hole.
Repeated treatment of plants during the growing season.
Constant control of plantings and the timely removal of diseased plants along with a clod of earth.
Sick plants must be destroyed: burned or buried in the soil to a depth of at least 0.5 m.
Annual change of plot for annual plants and bulbous plants.
The early excavation of bulbs before high temperatures and complete yellowing of the aboveground part of the plant.
Thorough cleaning from the site of all plant residues, on which the culture of the fungus, the causative agent of the disease, can subsequently develop.
Observance of the conditions for the cultivation of flower crops, since the moist environment, the absence of bright light and the acid reaction of the soil are favorable conditions for the development of fungal parasites.
Already at the beginning of summer, spotted flowers and raids may appear on flower plants. The source of contamination is the last year's plant remains uncleared from the site. On plants with overwintering leaves, for example, on primula, badana, spots are already visible from the spring.
and groups of attacks include a number of quite dangerous viral and bacterial diseases of flower crops that can significantly reduce the decorativeness of plants and even become a threat to their life. Pestarepestnost is especially massive in affecting tulips, but it also poses a danger to lilies on which they can live without manifesting symptoms.
Mosaic exists in a number of forms depending on the affected culture: a mosaic of daffodils, a yellow mosaic of gladiolus, a cucumber mosaic of gladiolus. Mosaic also affects tulips, peonies, dahlias, chrysanthemums, lilies, violets, asters.
This powdery mildew affects many plants: asters, chrysanthemums, marigolds, snapdragons, carnations, delphiniums, forget-me-nots, roses, phloxes, violets, pansies, lilacs, etc. Downy powdery mildew occurs in many flower crops - on anemones, lion throat, carnations, marigolds, forget-me-nots, fragrant peas, roses, violets, etc. Fighting with patches and plaques consists of both protective and preventive measures.
Viral diseases, which include patchiness and plaques, are often transmitted mechanically through infected instruments. Therefore, knives and pruners should be thoroughly disinfected after working with potassium permanganate, a strong solution of soda.
For preventive purposes, the soil 2-3 weeks before the landing of the pilots in the ground can be spilled from the watering can with a solution of copper sulfate( 1 tablespoon per 1 bucket of water).When spots appear on leaves, plants are sprayed with copper chloride solution in accordance with the instructions for use. The concentration of any copper-containing drug in the range 0.3-0.4 %. For all flower crops, it is advisable to carry out the first treatment against spotting as early as the beginning of June. In autumn, perennial cultures are recommended to be re-processed after flowering. The main protective measures for the protection of plants from all forms of patches and raids are careful collection of plant residues in autumn and spring after the opening of plants, the culling of diseased plants and the use of copper-containing preparations.
A number of flower crops are affected by such dangerous bacterial diseases as scab and growth, the causative agents of which are bacterial pathogens.
Parim affects gladioli, dahlias, irises and freesia.
Growing. This disease is also called gladiolus cancer. It strikes gladiolus, dahlias, carnations, delphiniums, sweet peas, chrysanthemums, lilies, nasturtiums and petunias.
