Disease Control

Fungal diseases

disease control and prevention

Fungal disease can be detected if there is rot or melt in the leaf and root system.

Treatment of leaf fungal and root system fungal diseases should be treated separately.

Prevention of fungal disease control by preventive treatment before the onset of disease is beneficial for optimal growth of the plant.

Prevention of fungal diseases on leaves

Two different agrochemicals recommended for fungal control should be published on rotating leaves every two weeks.

Selecting a specific day of the week will help you get the right treatment.

For example – if you can easily book a Saturday, you can use Saturday mornings every week. If one day the remedy is missed, you can choose a date that is close to it.

Every month

  • The first week – For the control of fungi
  • Second week – For insect control
  • Third week – For the control of fungi
  • Fourth week – For insect control

The following are the concentrations of the recommended agrochemicals for fungal disease control

  • Brand name Chemical name concentrations(For 1.5 liters of water)
  • Antracol Propineb 2.5gr
  • Baycor Bitertanol 2.5ml
  • Ronil Chlorothalonil 2.5ml – 5ml
  • Daconil Chlorothalonil 2.5ml – 5ml

Remedies for Fungal Infections in the Root System

  • A fungal infection of the root system can be inferred if the dark yellow color of the plant begins with mature leaves and spreads to the leaflets.
  • As a precautionary measure, preventive remedies should be applied to the recommended soil fungicidal media every two weeks.

Recommended Soil Fungicides

  • Brand name Chemical name concentrations(For a bucket)
  • Pomarsol – Forte Thiram Stuffed teaspoon 2
  • Monceren Pencycuron Stuffed teaspoon 2
  • Topsin Thiophanate Methyl Stuffed teaspoon 1
  • Homai Thiophanate Methyl + Thiram Stuffed teaspoon 1
  • Antracol Propineb Stuffed teaspoon 2

Deficiency disease control

Deficiency diseases are seen in crops that are not well maintained. Symptoms of new leaves and flowers that develop after a short period of time are not show.

Nitrogen deficiency

The entire plantations are uniformly yellow. This condition is caused by the lack of fertilizer as well as the growth of mosses on the media.

The roots should be fed with Osmocote N plus the leaves should be fed Leili or 30 + 10 + 10 nitrogenous liquid fertilizer.

If the liquid has developed on the medium, remove the slab layer by hand and apply a fungicide solution.

Trace elements deficiency

The leaves are colored dots or spots. This condition can be prevented by applying particulate matter.

Examples of fertilizer containing trace elements

  • Vegtrac – 1.5 to 1.25ml of water
  • Vegimax – 1.5 liters of water – 1.25 ml

If no symptoms are present in the newly formed leaves, it can be concluded that the deficiency is cured.

Phosphorus (P) fever

The buds of newly formed leaves are short. For roots, Osmocote N Plus can be gradually recovered by applying a high dose of 10 + 52 + 10 phosphorus to the leaves.

Moisture thickening

The leaves are provided with a coarse texture. This characteristic can lead to a decrease in the quality of small plants. To maintain the moisture content of the water vapor, place the plant in a shade net and apply water daily.

Bacteria diseases

Xanthomonas = Ervinea – Bacteria cause infection. For plants obtained from well maintained cultivation

For plants obtained from well maintained cultivation Bacteria There is no chance of disease.

In the case of fungal disease, a diagnosis of bacterial disease is often seen by apprentices to anthurium cultivation

It is speculated that may have contracted a bacterial infection If, the plants should not be sold.

Several medications can be used as a remedy for Bacteria diseases.

Due to their complexity and to avoid unnecessary use of drugs, these drugs are not mentioned here.

It is best to protect the crops without causing bacterial diseases.

Pest disease control

Living organisms that are harmful to crops are known as pests.

There are a number of species that are known to be harmful to anthurium and their impact varies by region and with different weather conditions.

Various types of pests at the same time will only cause damage to the crop. Therefore, it is important to make time to look after the crops you have built.

Various strategies are used to control the pest.

There is a special type of nets called Insect Proof, which is manufactured exclusively to prevent insect infestation, Insect Proof mesh is not suitable for commercially run anthropoem plantations.Cultivation of the nets can cause stress due to the lack of ventilation

80% black shade nets are difficult for many pests to access, but shade nets are not a hindrance for small animals such as mites and thrips. In such cases, the application of topical agrochemicals may help prevent damage.

Insects cannot eat the foliage or absorb the sap because the agrochemicals in the plant remain in the tissue for a certain period of time.

The applied agrochemicals should be re-applied at the end of the active period.

Dumb oysters are not found in the shade nest house, and they are only found when the coconut husk media is grown. Pests such as caterpillars, and crocodiles can be caught and removed.

Prevention of pesticides which are harmful to crops


In all parts of Sri Lanka, pests that have the most impact on anthurium cultivation are mite infections.

The juice of the little leaves or the flowers suck up on the underside of the leaves.

If not suppressed quickly, the damage worsens and the plantation deteriorates.

How to detect infections

Flexibility is naturally present in the leaf, so it bends when folded.
White spots appear on leaves.


Preventive Remedies

Spray two different agrochemicals on the leaves on a given day for rotation every two weeks.

Applicable agrochemicals

  • Zoro, mig-18, Jet, Nissorun
  • 5ml/75g per 1.5 L of concentrated water


Aphides, a tiny creature, comes into the shade from the shade nets and sucks the juice out of it.

How to identify the infection

The edges of the little leaves and buds do not protrude. Due to the absorption of the juice, the leaves and buds are twisted.


Preventive Remedies

Apply recommended systemic agrochemicals

Examples – Admire

Concentration 2.5ml-5m for 1.5 L of water

white fly

the leaves are twisted and the quality of the plants is lost.

Acting as a carrier of disease in propagating fungal and bacterial diseases

After laying eggs in the plant’s stem or near the root system, the larvae suck out the juice, leaving the root and root system of the leaf black and the leaves crumbling.

How to identify the infection

On the underside of the leaves. As the population grows, the surface of the leaves becomes black dots.

The tiny white creature can be observed in a well-lit environment.


Remedies for Suppression

Apply the recommended systemic agrochemicals.

Examples : Admire, Lebaycid, mightee, zoro, Mig – 18 Concentrate for 1.5 L of water – 2.5 ml – 5ml.

Leaf miner

Staying in the garden damages the inner tissues of the leaves and eats the layers of cells beneath

How to identify the infection

The inside of the sheet shows lines like a map.

Remedies for Suppression

Examples : include mightee, zoro, Mig-18, Jet Concentration for 1.5 L of water 5ml 88 89 doo – Mealy Bug.

Mealy Bug

The juice of the underside of the leaves sucks.

Once infected, the leaves dry up and the plants die.

It must be quickly suppressed as it is highly contagious.

How to identify the infection

Leaves are brownish-brown.

If you look down the sheet you can see that as the root of the Narrator is a white cotton cloth.
