The use of biological fungicides is a major requirement for orchid plants. Orchids grow and live with the help of symbiotic microorganisms, given their particular root system, and one hundred percent say that without these microorganisms, they cannot grow and live in normal conditions.

Diagnosis of orchid disease

To use fungicides you need to make sure that your orchid disease is related to bacteria and fungi. Bacteria and fungi attack all orchid species. When phalaenopsis orchids are infected with orchid fungal or bacterial disease, speed of action is important in controlling and treating the disease. Colorless leaves and unpleasant odor are two of the hallmarks of a bacterial infection. Orchid fungicides from Nikooraee’s company are capable of killing bacterial pathogens. Bacterial diseases are caused by high temperatures and high humidity and usually have visible symptoms. If you see brown or soft spots on the orchids during your daily inspection, it is most likely a bacterial disease.

The most common orchid diseases are:
Treatment of bacterial brown spots with orchid fungicide: As a soft, watery lesion, it usually develops on the orchid leaf and eventually turns brown. In the advanced stages, the brown spot starts to release a dark liquid.
Soft bacterial blotch and treatment with the fungicide of Nikooraee: it begins with a watery blotch with an unpleasant odor on the orchid leaf. The infected area expands rapidly and the whole leaf becomes soft and thin within 1 to 2 days.
Crown rot fungus and prevention and treatment with orchid fungicide: The most common and dangerous orchid fungal disease. Orchid growers may notice a slight discoloration at the center of the plant or at the base of the leaves at the onset of the disease. Crown rot is caused by a combination of water shrinkage, poor air circulation, and low temperatures. If left untreated, the plant may disappear within a week.

Orchid Disease Control:
Immediately remove contaminated foliage with a sterilized razor (with 70% alcohol or Nikooraee fungicide). Move your orchid to expose it to better air circulation, low humidity, and temperatures between 24 and 29 degrees Celsius. Treat your orchids with high-quality biological fungicides. Even if you think the agent is a bacterium, use fungicides because the use of fungicides prevents secondary infection.

Black rot and its treatment with biological fungicides: This disease is a danger to orchids whenever the weather is rainy or humid. Black rot can quickly destroy an entire plant if it is not controlled. Black rot occurs in one or both of the Pythium ultimate and Phytophthora cactorum fungi and affects a wide range of orchids. Catelia orchid appears to be more susceptible to this disease. The black rot agent moves quickly inside the plant and, if left untreated, can destroy the whole orchid plant.

The life cycle of the disease agent
You need to know the pathogen to use the right fungicide. Fungi that cause black rot in orchids can only live in environments where water is available. They are composed of spores capable of independent movement. These spores are called zoospores that swim through water. If water accidentally sits on orchid leaves, zoospores can penetrate the plant tissue and begin the next phase of their life cycle. The biological agent present in the fungicide Nikooraee can hunt and kill these spores. At this stage, the fungus forms a vegetative or mycelium consisting of hyphae (narrow tubes and yarns) that spread rapidly between the damaged plant tissues. After the onset of the disease, visible symptoms of infection include small watery, translucent spots that spread rapidly and turn brown and then black. If left untreated or damaged, healthy plants can infect and possibly die.

Spraying orchid fungicide on the soil is important because when the fungus invades the seedling, it usually happens in the soil that it can kill small plants. In mature plants, the disease can occur anywhere on the plant (leaf, stem or root). But it often starts in new or growing leaves and goes down to the roots within the plant. As its name implies, black rot appears as dark black spots on different parts of the damaged plant. Spray the fungicide directly on the infected parts in the second step. Black spots grow rapidly and can spread throughout the plant. If it reaches the crown of orchids that are single-stem, it kills the plant. Injured leaves may turn yellow around the infected site and release material if pressed.

Prevent disease
Along with the use of orchid, fungicides are other things to keep in mind. Contaminated pots with other pots, food or water sources, as well as sprinkled water from adjacent infected plants are all great ways to spread the fungus. In addition, outdoor plants should be 90 to 120 cm high above the ground to avoid contamination by soil and water particles. When transporting the plant, be sure to soak the roots with a biological fungicide. Don’t let the leaves of your orchids stay moist for a long time. Good air circulation is very important and can help plants dry out after the rain. Adding a fan to the greenhouse can improve airflow and help prevent dew. In the first signs of infection, remove all damaged plants from the vicinity of healthy ones to avoid contaminating healthy plants. The use of orchid fungicides for healthy plants is effective in raising them against pollution. Some growers recommend using high-calcium fertilizers in the spring to prevent black rot in the new season.

Phyllosticta leaf spot
Leaf fungi of Pyllosticta Phyllosticta Capitalensis spread easily and cause ugly spots on the leaves of orchids. It is common in warm climates, but the disease is present in a number of different orchid species worldwide. This pathogen is also known as Guignardia. These names are two sexually distinct stages of the fungus. Dendrobium and Vanda’s plants are most susceptible to this fungus. Removing the pathogen from the orchid is almost impossible, but biological fungicides can completely eliminate it. With specialized tracking of the fungus in the plant.
