Plants Illnesses

Plant diseases are caused by fungi, viruses, bacteria, and non-living factors. Plants are more inclined to get sick if there is too much organic matter on the ground (eg, too much fertilization with nitrogen), in unpleasant weather conditions and if the plant has been subjected to stress. Therefore in adverse terms, we strengthen plants with different preparations in time.

Diseases caused by fungi

Most fungus-related conditions are linked to a plant family. The measures stand out. Therefore they are described under specific diseases.

Alternariosi

Attacks fruit vegetables, endive, radicchio, legumes, bulb vegetables. We recognize it thanks to concentric circles on the spots that are found on the stems, the leaves, and the fruits.

Protection and help:

  • moderate fertilization;
  • distances between the rows large enough to allow air circulation and quick-drying;
  • strengthening of plants with different preparations;
  • prevention with milk preparations, apple vinegar, elderberry leaves or chamomile tea;
  • care with sage tea, thyme, or horsetail.

Potato mildew

Attacks Solanaceae: potato, tomato, pepper, aubergine. It is recognizable by the gray-black spots on the stem, on the leaves, or the fruit.

Protection and help:

  • moderate fertilization (if it often occurs we plant the Solanaceae on a different parcel);
  • distances between the rows large enough to allow air circulation and quick-drying;
  • strengthening of plants with different preparations;
  • use of less sensitive cultivars;
  • a quite large turnover;
  • we transplant small-sized shoots, as those that are too large do not bear the changes well;
  • we do not touch the plants when they are wet or humid;
  • plant the potato as far as possible from the tomato and do not perform work on both plants at the same time;
  • we remove the lower leaves and the little bitches of the tomato and thin the leaves on the whole plant (up to 5 a week);
  • prevention with preparations (sprayed products) of chamomile milk or tea;
  • care with onion, garlic, sage, horsetail preparations;
  • in case of severe attack elimination of diseased plants.

Erisifacea

It attacks almost all vegetables, most often parsley, radicchio, and cucurbits. We recognize it from the gray spots on the leaves of plants.

Protection and help:

  • regular maintenance of soil moisture;
  • among the plants we sow the basil, in the vicinity instead of bulb vegetables;
  • when it appears for the first time, we clean the plants with delicate water jets;
  • when rinsing is no longer helpful, we cut parsley and radicchio and leave only the central leaves;
  • care with garlic preparations, apple vinegar, ponytails, elderberry leaves, nettles, chamomiles.

White mold

It attacks almost all vegetables, most often beans, peppers, and composites. We recognize it from the hair on the damaged parts (plant stems).

Protection and help:

  • moderate fertilization with nitrogen;
  • distances between the rows large enough to allow air circulation and quick-drying;
  • significant turnover is essential;
  • maintenance of light earth;
  • use of preventive preparations of sage, chamomile or compost;
  • we maintain cleanliness and regularly eliminate parts of damaged or decayed plants.

Gray mold

Attacks almost all plants. We recognize it because the leaves and fruits rot, the frame on the damaged parts is gray-green.

Protection and help:

  • moderate fertilization with nitrogen;
  • distances between the rows large enough to allow air circulation and quick-drying;
  • use of mulch, which prevents the humidity of the leaves and fruits;
  • maintaining light earth;
  • use of sage, chamomile or compost preparations;
  • we maintain cleanliness and regularly eliminate parts of damaged or decayed plants.

Lettuce downy mildew

Only attack the salad. We recognize it from the pointed yellow leaves, limited by the veins, they appear before on the outer leaves. Later the leaves turn brown.

Protection and help:

  • use of less sensitive cultivars;
  • quite a large turnover;
  • distances between the rows large enough to allow air circulation and quick-drying;
  • we cultivate lettuce on the second or third parcel;
  • prevention with preparations (sprayed products) of chamomile milk or tea;
  • care with onion, garlic, and sage preparations.

Ficomiceti

They attack many vegetables, most often cucumbers.

Protection and help:

  • moderate fertilization;
  • distances between the rows large enough to allow air circulation and quick-drying;
  • use of less sensitive cultivars;
  • a quite large turnover;
  • prevention with preparations (sprayed products) of chamomile milk or tea;
  • care with onion, garlic and sage preparations;
  • since we are unlikely to stop the attack, we take the risk into account, and we keep extra ready shoots to plant new plants.

Plant death

They attack the sowing and the new plants. We recognize it from the withering of plants in typical circles.

Protection and help:

  • use of healthy substrates without too much organic matter (peat);
  • we put the seed to soak in the sage tea and water the substrate for sowing with sage tea;
  • homogeneous watering, not exaggerated (with sprayer);
  • maintenance of hygiene in greenhouses, regular airing;
  • thinning in time, tapping or sparse seeding, because there is enough space between the plants;
  • when it appears we uproot the damaged plants and their neighbors, we dry the arable land and water with sage tea, after which we reduce the watering and increase the airing.

Rust

Attacks numerous plants. We recognize it from spores if we touch the contested parts, so it cannot be replaced with bacterial infections.

Protection and help:

  • moderate fertilization;
  • distances between the rows large enough to allow air circulation and quick-drying;
  • use of less sensitive cultivars;
  • quite a large turnover;
  • prevention with preparations (sprayed products) of chamomile milk or tea;
  • care with onion, garlic and sage preparations;
  • since we are unlikely to stop the attack, we take the risk into account, and we keep extra ready shoots to plant new plants.

Virus

We recognize viral diseases from wrinkled, curled or twisted plants and leaves (which are not the consequence of lice), unusual patches and leaf colors.

Protection and help:

  • since they are transmitted by sucking insects, we must drive them away, even providing for useful organisms.
  • They are also transmitted with seeds and parts of plants, so we provide certified shoots and seeds.
  • We provide resistant cultivars.
  • Many viruses are found on tobacco, so smokers must wash their hands thoroughly and not smoke on the garden before starting work.
  • We take care of plant health, as viruses do less damage to healthy plants.

Bacteria

Bacterial diseases are recognizable by the drops and circles of water on the spots that are the cause of bacteria. They are frequent when the weather is wet. The damaged parts have a terrible smell, the plants and fruits rot.

Protection and help:

  • We take care of plant health because, on weak plants, they do more damage. We fertilize properly and provide light soil.
  • They are also transmitted with seeds and parts of plants, so we provide certified shoots and seeds.
  • We provide resistant cultivars.
  • Beans are susceptible, so we don’t plant them until it’s too cold; we provide rows with good air circulation and adequately distant from each other.
  • The rot of the cruciferous trees causes triangular spots from the edge of the leaf towards the yellow and then brown petiole and in the event of a stronger attack, causes the withering of the plant. Providing plant health is the only help.
