What are the most common diseases of plants?

The first organisms that can cause disease in plants are fungi, bacteria, viruses, and nematodes.

Plant diseases caused by fungi

According to the affected plant part, we can classify viruses, such as:

  • Conditions of the aerial part of the plant.
  • Disorders and root.
  • Vascular diseases or trichomycosis.

In the first group, they are among others, oídiums, which at this time of year (spring), tend to show up in many vegetables.

Detection How to recognize hate in plants?

Powdery mildew or powdery mildew is a disease caused by parasitic fungi ericifolia all crops.

Are easily identified by presenting a whitish mycelium (like flour), which is visible to the naked vista.encase of outbreaks affect them can cause deformations even to dry them.

A very typical powdery mildew, caused by the fungus Sphaerotheca pannosa, is usually seen in roses and other ornamentals.

Combat powdery mildew

As always, preferably, we recommend products and preventive actions.

Well, we have fungicides, which, together with sulfur-based products ( consult fungicides ), are the basis of prevention.

However, if we are presented with a flattering spring fungus, or we have neglected to treatment, we can resort to overall systemic Fungicide, which has a curative action, allowing us to new shoots, leaving healthy and clean.

Combat Mildew

With warm and humid weather attack the new shoots in spring, and if this fungus is not combated, it detracts from the weakening damaging their foliage plants.

It is necessary to remove debris from the affected plants preventing the infected foliage remains in the garden for future infections. Apply fungicides.

Fungicides

Combat browning of conifers

Soil fungus Phytophthora, especially conifers in yours and cypresses (eye hedges formed by such plants), whose main symptom is the foliage desiccation, which turns brown, from the inside out.

Infection occurs in the root system and is favored by an excess of water (puddling) on ​​the ground.

Not overwater. There are specific fungicides.

Roya combat

It is producing fungus stains and colored bumps on leaves and stems.

Remove the affected parties and treated with a fungicide as soon as possible.

Combat Bacteriosis

Some bacteria infect our plants, producing them spots on leaves or soft rots malodorous.

It is best to remove the affected areas or whole plants.

Combat Botrytis or gray rot

The fungus Botrytis cinerea appears with high humidity, puddling, or excess water.

Affects leaves, stems, flowers, and fruits, which are covered with gray rot mold.

Avoid injury as it penetrates out there on the ground.

Remove the affected parties and deal with anti botrytis fungicide.

A virus in plants, the Virosis

Germs and bacteria with fungi are the microorganisms causing plant diseases. They produce very different symptoms.

Viruses usually do not cause plant death, but reduce their ornamental value and vigor.

Viruses are hopeless.

The only solution is to start the affected plant and burned to prevent contagion.

Recognize and treat Negrilla

It looks like a black powder covering leaves, branches, and fruit. This fungus appears on molasses (sugary liquid) that excrete aphids, scale insects and whiteflies.

It is not severe, but it gives a bad aesthetic appearance and hurt losing vigor.

Fungicides usually not applied directly against Negrilla but the fight mealybugs, aphids, and whiteflies, which are the insects that occur due to the Beleza.

How to fight these diseases of plants?

Keep healthy and vigorous plants. Preferably parasites attack weak plants. Water and fertilize regularly but without excess.

When the weather is beautiful, you must pay attention because they start fungal attacks (Video, Milidu, Roya, Botrytis, etc.) and pests (aphids, mealybugs, whiteflies, red spider, etc.)

Collect and burn the leaves that have been attacked by fungus.

Used insecticides and fungicides for use in organic farming as sulfur or copper (Bordeaux mixture. Fungicide against mildew and Botrytis It is a mixture of copper sulfate, lime, and water).
