Peronospora

Peronospora

Peronospora is very dangerous for agriculture because of the economic consequences that a crop loss can cause to the producers of fruits and vegetable or other plants. In humid areas, the peronospora attacks more frequently vines and creepers. Since it is a parasite, peronospora’s life purpose is to reproduce and survive. It attacks the leaves first, and when it has no more substance to get food from, it starts attacking the fruits. The typical stains are yellow, brow or purple. It follows a sort of film made of mold, causing the fall of the leaves. Humidity and temperate areas are the peronospora’s favorite environments, but it is not only a matter of temperature and wetness, because this fungus can arise due to bad trimming and reproduction cuts, that could get the plant wicker and vulnerable to external bad agents.

Peronospora prevention's

You can prevent peronospora by limiting the presence of those conditions favouring the development and the propagation of the fungus. Reduce the irrigation and avoid water stagnation. For ornamental plants it is better to place them in dry molds, sunny places, repaired from the wind. Keep the trimmings constant and try to make stronger grafts proliferate more than the weak ones.

    Remedies

    RemediesAnti fungal and anti-parasites are the typical remedy for peronospora. In some cases you can use products which go work directly on the parts of the plant affected by the disease. Other should be sprayed before the fungi have actually allowed the beginning of a disease, going to work directly on the spores. Be sure you are going to use the right active principle fighting the fungus and not the positive elements of the plants. Sometimes other kinds of fungi are used to fight against the peronospora, adding them to a mixture made of copper and other combined substances. These solutions must be applied melting them into water and then spraying them on the damaged parts of the plant. They can be added to the water used for irrigation, in order to let the plant absorb the remedy without getting damaged by the mix of sun exposition and sprayed solution which could cause burning and dryness.
