How to Get Rid of Phytophthora in Soil: Secret Methods of Professional Gardeners

Phytophthora is a real nightmare for any gardener. This fungal pathogen can destroy an entire crop in a matter of days.

Anastasia Kovrizhnykh, an expert of the online publication "BelNovosti", an agronomist and landscape designer, reminded summer residents of the most important thing.

Understanding the Nature of Phytophthora

Phytophthora belongs to the class of oomycetes and is a dangerous pathogen that affects various crops.

Tomatoes, potatoes and other nightshades are especially vulnerable to it.

The fungus spreads quickly in conditions of high humidity and moderate temperatures, which makes it especially dangerous during rainy seasons.

Preventive measures

Preventing the occurrence of late blight is a key aspect in the fight against it.

Gardeners are advised to select disease-resistant plant varieties and practice proper crop rotation.

It is also important to ensure good air circulation between plants, avoiding dense plantings.

Agrotechnical methods of control

To effectively get rid of late blight, it is necessary to use a range of agricultural measures.

Mulching the soil helps reduce the risk of infestation by preventing leaves from coming into contact with contaminated soil.

Regularly removing the lower leaves of tomatoes and potatoes will also help reduce the likelihood of infestation.

Biological means of protection

The use of biological preparations is becoming an increasingly popular method of combating late blight.

Trichodermin and Fitosporin are examples of effective biological agents that suppress the development of the pathogen without harming the environment. These preparations contain beneficial microorganisms that compete with late blight for nutrients.

Chemical methods

In cases of severe infestation, the use of chemical fungicides may be required.

Copper-based products, such as Bordeaux mixture, have proven themselves to be effective in combating late blight. However, it is important to remember the need to alternate products to prevent the pathogen from developing resistance.

Folk remedies

Many gardeners successfully use folk methods to combat late blight. A solution of whey or garlic infusion can serve as an effective preventive measure.

Spraying plants with a weak solution of potassium permanganate also helps strengthen their immunity and resist disease.

Improving soil structure

Healthy soil is the basis for plant resistance to diseases. The introduction of organic fertilizers, such as compost or humus, promotes the development of beneficial microflora, which naturally suppresses pathogens, including late blight.

Proper watering

Watering regime plays an important role in preventing late blight. Avoid over-wetting the soil and water getting on the leaves of plants.

Drip irrigation or root watering helps minimize the risk of disease development.
