Plants can have various diseases, both in private gardens and in greenhouses. The most common ones are diseases that come from different types of fungi.

They can damage and sometimes destroy the structure of plant tissues and their physiological functions. Below are a few vivid examples of this type of disease.

Powdery mildew

It’s a disease caused by powdery fungi. One of the symptoms is the formation of plaque on the leaf plate and the stems of plants. The leaves affected by powdery mildew will soon wither. This disease can also lead to buds drying out and falling off and slowing down or even stopping the development of shoots. This type of fungus is transmitted by spore dispersal or along with cuttings.

The stages of powdery mildew treatment:

  1. Spraying infected plants with clean water;

  2. One-time pollination of the infected plant with ground sulfur;

Also, plants’ treatment with the copper-soap solution (a mixture of copper sulfate and soap) is encouraged.

Infected plants react well to being sprayed with an infusion from rotten leaves or hay.

If you do not have these products on hand, you can use a more straightforward method. You’ll need to mix:

  • 1g salicylic acid

  • 5mg denatured alcohol

  • 10g of soap

  • 3g baking soda

  • 0.5 gallons of water.

Infected plants should be treated with this mixture at least 3 times.

False powdery mildew

This disease is caused by the formation of gray plaque on the bottom side of the leaf. The plaque turns yellow and then brown. In general, this disease is caused by excessive humidity or incorrect watering. Plants that are affected by false powdery mildew usually appear less healthy.

It is beneficial if you manage to detect the disease at an early stage since there is a chance to cure the plant. All you need to do is use products that contain copper (copper sulfate, Bordeaux mixture). Diluting 5g of the drug in 1 liter of water is enough for the solution.

Use this solution to treat plants 2-3 times at intervals of 10 to 20 days. The diseased parts of the plant should be removed and burned. Sometimes, however, the disease progresses and goes too far. In this case, the plants must be removed and destroyed.

Gray mold

The sources of infection are conidia and sclerotia, which are found in soil and plant remains. Signs of gray mold are the appearance of gray fluffy mold on plants.


  • timely removal of the diseased areas of the plant;

  • treatment of sick plants with systemic fungicides (medicine for fighting broad-spectrum diseases).

It’s recommended to reduce the watering of the plant during the treatment period.


Chlorosis is a reasonably common plant disease that develops because of a lack of chlorophyll in plants.

Signs of chlorosis can vary: yellowing of the leaf plate, changing of the leaf shape and twisting of its edges, shedding, changing of the bud shape, which can sometimes lead to withering and even death of the plant root system.

The treatment is quite simple: transplant the plants into more suitable soil in a lit area and fertilizes them with iron-containing fertilizers.


Fusariosis is one of the most dangerous fungus diseases. The signs of the disease are yellowing, drying out and withering of the plant. The disease is the result of root and bulb damage (rotting of the bulb in the bottom area during cultivation or at rest). Fusariosis is spread by dry brown-red spots, which get covered by light pink plaque as time goes by.

Treatment of this disease consists of watering sick plants with a mild solution of potassium permanganate at least 3 times and brilliant green dye treatment. To prevent fusariosis, you can put the cuttings into the 0.1% potassium permanganate solution for about 2 hours before planting.

Each year, various diseases cause huge damage to crops, which can eventually destroy the economies of different countries that depend heavily on the export and import of agricultural products. You can protect the plants from these diseases by following simple steps: proper care, timely watering, fertilization and plant treatment.

Automated IOGRU systems can simplify all these tasks and even more – prevent the possibility of diseases. With these systems, all your crops and greenhouse functions are under your full control, wherever you are.
