Downy mildew symptoms

The symptoms of downy mildew at the beginning can be confused with other infections manifested by various types of spots on the leaf blade. However, if we look at the lower side of the leaf, we will notice a white, powdery coating at the discoloration site - clusters of powdery mildew mycelium.

Before we reach for chemical preparations to fight infections, let's first give a chance to home-made, natural methods that will not harm us or nature. Here are some of the methods already used by our grandmothers.

Soda in the fight against mildew

Soda in the fight against fungal diseases is as effective as specialist preparations available for sale.

To prepare the preparation, take 4 grams of baking soda and dissolve it in 1 liter of water, and then add 4 grams of gray soap. Mix thoroughly and spray infected plants several times at intervals of 7 days.

To make another measure, dissolve 5 grams of soda ash, half a teaspoon of liquid soap and 1 g of copper sulfate in 0.5 l of water. Then add another 0.5 liters of water and spray the plants with this solution. This measure can also be safely used in homes.

Emulsion with wood ash

Take 0.5 cups of wood ash and pour 1 liter of boiling water over it. Leave for 2 days, then strain and add 4 grams of gray soap. Use every two days, but no more than three times.

Manure

When preparing a manure-based preparation, take 1/3 bucket of fresh manure and pour water over it. Set aside for 3 days, stirring occasionally. Then strain, and before spraying, dilute with water in a ratio of 1:10. Plants should be sprayed in the evening to avoid sunburn.

Curdled milk or kefir

The liquid leaves a thin protective layer on the leaves, and the protein under the influence of the sun has a lethal effect on the fungal spores.

We prepare the spray mixture from the separated sour milk whey or kefir, diluting 1: 10 with cold water. We spray the plants prophylactically.

Jodyna

Experts believe that, preventively and at the first signs of the disease, iodine solution is very effective and also safe. To prepare an agent against powdery mildew, dissolve 1 ml of iodine in 10 liters of water and spray the infected plants.

Mushrooms in the fight against mushrooms

Yeast used in the form of a spray after spraying on the plant colonizes its leaves, displacing microorganisms harmful to plants. Thanks to this, yeast creates a natural barrier that protects the plant against fungal infections

To prepare a spraying solution, dissolve 100 g of baker's yeast in 0.5 liters of 3.2% milk. We dilute with 10 liters of water and add approx. 30 g of gray soap or a few drops of dishwashing liquid to increase the adhesion of the preparation.We spray every week throughout the growing season.

Plant preparations in the fight against downy mildew

Nature is an endless source of raw materials that we can use to fight plant diseases and pests. To combat downy mildew, try the methods that have been used for a long time in amateur plant cultivation.

Onion infusion

Pour 100 grams of onion husks with 5 liters of hot water and let it brew for 1-2 days. Then strain and you can spray the infected plants.

Decoction of onion husks

To prepare the stock, take 200-500 g of onion husks and add 10 liters of water. Leave for 12-24 hours, then cook for 0.5 hours. Spray with undiluted decoction every 3-4 days.

Yarrow extract

Add 1 kg of fresh or 100 g of dried herb to 10 liters of water. Leave for 24 hours. After dilution with water in a proportion of 1: 10, spray the yarrow of infected plants.

Horsetail manure

Prepare 1 kg of fresh herb or 150 dried horsetail and pour over 10 liters of water. Leave for 2 weeks. Spray and water the plants with manure diluted with water in a ratio of 1: 5.

Dung with garlic, onion and blackcurrant leaves

Both garlic, onion and black currant leaves are natural fungicides. See how to make slurry of them to combat downy mildew.

50 g garlic heads, onion husks and blackcurrant leaves in equal proportions pour 10 liters of water and leave for 2-3 weeks. Strain and dilute 1:10 with water. Spray the prepared liquid every 3-4 days.

Nettle slurry

Take 1 kg of fresh herb and add 10 liters of water. Leave in a closed container for 2-4 weeks until it starts to ferment. Spray with nettle slurry diluted with water in the proportion 1: 10.
