Remedy for mildew - these really help!

The Content Of The Article:

Basically, a distinction is made between real and downy mildew. Both diseases are caused by different fungi, have different symptoms and types of control.
Symptoms of powdery mildew
The powdery mildew predominantly affects leaves. The pathogen is a fungus (Ascomycota), where there are special fungi that specialize in certain plant species (cereals, pasture grass, wine). Evident is the infestation of an initially flour-like coating on the top of the sheet. Over time, the leaves will turn brown, become brownish and dry. At an advanced stage, shoot tips, buds and fruits can also be affected. The mushroom hibernates on the plant. Dry weather favors its distribution, which is why it is also called fair weather mushroom. However, he also likes hot and humid weather and strong temperature fluctuations between day and night, as they often occur in the fall. The hose fungus finds good conditions at temperatures above 20° C and a humidity of about 70 percent. In late autumn the mushroom forms winter fruit body. These overwinter in the fallen leaves, but also in plant remains from the environment. There are exceptions to the normal appearance. Strawberries do not show the floury coating on the leaves. In contrast, the underside of the leaves turns red. The leaves curl upwards. In grapevines, the infestation looks similar. Here it comes with the progression of the disease also to bursting of the grapes.

  • Fair weather fungus
  • May temperatures between 20 and 25° C and dryness
  • Individual mushrooms have a specialization in certain plants
  • Particularly affected: roses, asters, carrots, gooseberries, cucumbers
  • Spores are mainly spread by wind and insects
  • Hard winters are no problem
  • Wintering spores survive in fallen leaves and plant remains
  • First symptoms appear early in the year
Symptoms of Downy Mildew
In case of downy mildew, the pathogen, in this case an egg fungus, penetrates deep into the plant. This also produces a whitish coating, but at the bottom of the leaves. On the upper side of the leaves are reddish-purple spots, sometimes yellow to brown spots, which remain bounded by the leaf veins. Buds and shoots dry out and in the end even the fruits. In contrast to powdery mildew, the wrong one grows better in humid and moderately warm to cool weather. In addition, too high a nitrogen content in the soil favors the spread. The fungus is constantly forming new subspecies, which makes the fight easy.
  • Bad weather fungus
  • Affects both ornamental and vegetable plants
  • Mushroom penetrates into the plant, lives between the cells
  • Mushroom grows outward
Spore carrier on the leaf undersides
  • Infestation much later than with powdery mildew
  • Mushroom hibernates in the shoot tips, under bud scales or in fallen leaves
Prevent mildew
Preventing this fungus infection is better than curing. This starts with the selection of robust or resistant varieties, goes through the right location and substrate for the plants and woody plants, to care, so the plants, irrigation, fertilization, cutting and hibernation. Plant Tonics help to strengthen the plants. Healthy and strong plants are better able to defend themselves against pathogens. Field horsetail broth is very effective. In addition, an overdose of fertilizers must be avoided, especially of nitrogen. Sufficient distance to neighboring plants ensures that the leaves can dry better, do not stay wet or moist for too long. Even a regular cut is helpful.
  • Select resistant plant varieties
  • Are not there any, resort to resistant varieties
  • Sufficient planting distance
  • Suitable location
  • Good air circulation
  • No damp and shady places
  • Plant Strengthener - Horsetail broth, garlic broth
  • Certain herbs interbreeding, chervil, chives, basil
  • Targeted watering, do not pour on the leaves
  • Water in the morning instead of in the evening
  • Do not fertilize too much nitrogen
  • Soil mulching, weed removal
Combat mildew
It is important to remove the affected parts of the plant. This can be tedious to pluck the whole leaves, but it helps and that without chemistry. Even fallen leaves must be collected and disposed of. If shoots are involved, they should be cut away and disposed of as well.
Tip: Devices and cutting tools can adhere to organic material. This can hibernate fungal spores. Therefore, it is very important that after use everything is cleaned and cutting tools are also disinfected.
When powdery mildew initially helps the wiping of the leaves, if that is troublesome. It is easier to spray the infested plants. A home remedy is well suited, namely milk.The milk is diluted with water (1: 9) and then distributed on the plants. It is favorable to spray around, even from below. The treatment should be repeated once or twice, always every few days. If you do not like this method, you can not use any commercially or siliceous preparations from the trade. It is important to spray on a day when there is no rain. It is sprayed directly on the affected areas, but also around it. Extremely environmentally friendly is the use of beneficial organisms. These not only help to reduce insect pests, they are also ideal for crop protection. They harvest the mushroom turf. Unfortunately it grows again, but still it helps. Suitable are normal ladybirds, twenty-two point ladybugs and sawflies.
Tip: The collected or separated leaves and shoots do not belong to the compost. They are best disposed of in residual waste.
Alternatively, mildew can also be controlled by chemical means. There are broadband fungicides that help against various fungal pathogens and specialty products such as roses, vegetables and other plants. Some remedies help against both the real and the downy mildew, others only against one. Powdery mildew - rose mushroom free Saprol (Celaflor), rose mushroom free Saprol (Celaflor), Naturen net sulfur WG (Celaflor) especially for vegetables
Downy Mildew - Rose Mushroom-Free Saprol (Celaflor), Rose Mushroom-Free Saprol (Celaflor), Bayer Garden Special Mushroom-Free (Bayer)
A powdery mildew is usually the powdery mildew or downy mildew. Both are caused by fungi, but by different. So the symptoms are quite different. It is important to determine the mildew, because that is important for the fight. There are chemical remedies that help against both fungi, but especially with home remedies you only go against one of the pathogens. So he has to be identified correctly. The powdery mildew is easier to combat, because it remains superficial, does not penetrate like the downy mildew in the plant itself. Important is the prevention that it does not even come to an infestation.
