Today's article is dedicated to one of the pests of Cannabis that most concern growers, fusarium. It consists of a fungus that lives in the soil, in the substrate, and that can generate great damage to the plants since rot the roots. In the most serious cases it can ruin your crop causing the death of all the plants.

Prevention, once again, is the best alternative to get rid of this feared fungus. Therefore, we bring you very useful information of how to prevent it, how to detect it and how to eliminate it.

What is Fusarium?

Fusarium, refers to a genus of filamentous fungi, Which inhabit the substrate and which attacks the root system of various types of plants, including cannabis.

The Fusariosis is the name of the disease generated in plants by some of the species of fungi of the genus Fusarium (phytopathogens), which grow in this case as parasites.

The fungus is usually present in the warm and tropical regions of the world. It spreads through the movement of water and garden tools.

One thing to keep in mind is that this fungus can remain dormant for many years in the substrate and activate when it finds a viable host plant, such as marijuana and also the Weather is warm and humid. Therefore it is difficult to detect, because it may take years before you discover that this fungus has affected your harvest.

Fusarium disease is really a very bad disease for marijuana, affecting especially to roots and stems. Infected plants lose vigor, paralyze the growth or flowering and even dry the branches or the whole plant depending on how intense the attack is.

Fusarium affects cannabis plants in indoor, greenhouse and outdoor crops and can be generated on all substrates: earth, coconut, etc.

Cultivate hydroponically Marijuana plants are considered one of the best ways to prevent fusarium because the fungus can not survive without the soil.

However, if you do not like this farming system, you will have to know what are the factors that can trigger its appearance for be able to prevent it.

How does Fusarium work in marijuana?

The colonization of this fungus begins in the soil, through the roots reaches the stem, then moving to all areas of the plant through the vascular system.

The Fusarium fungus is colonizing the xylematic ducts of the plants, obstructing the vessels and preventing the transmission of water and distributing to all parts of the plant. This blockage causes the leaves and stems to wilt, generating a necrosis and, in most cases, death of the host plant.

How is Fusarium or Fusariosis identified?

Let's start with the signs that may indicate that our Cannabis plants are infected from Fosarium

The fungus begins attacking the roots. Obviously, we can not see this since the roots are buried underground. The roots rot and begin to turn reddish brown-brown. A few days later the root becomes woody.

The fungus blocks the entry of water and nutrients to the plant. As the symptom worsens, it begins to ascend quickly towards the stems and also to decompose. As a result, the plant will collapse and die.

One of the first signs that indicate that a plant may have a fungus, are the fallen leaves, with stains and after a few days, see a completely withered branch.

As for the stem, this fungus attacks from inside the xylem, from outside it can be observed as a watercolor stain (translucent) of a tonality dark brown. When the fungus advances, we will observe that the leaves are decayed as if they lacked water and the branches completely dry. If we cut the stem, we would see the brown vascular bundles.

We can also see exterior signs in the stem, where dark spots will appear and we can even see how a viscous liquid dark brown. When the fungus is widespread, we will see the Leaves down and decay of the general plant. In these cases the fungus penetrates through wounds or openings in the trunk.

If we look at the plant with a good quality microscope, we can possibly see the fungus spores. However we must be careful to disinfect the microscope very well before observing another plant for not infect other plants. The contagion by means of tools is very easy.

How to prevent Fusarium?

We always recommend preventing fungal diseases before seeing his appearance. They are really harmful, because they are practically impossible to eradicate.

Before a plague of Fusarium, you must get rid of the infected plants and monitor healthy ones, bearing in mind that possibly they are also infected because the fungus expands rapidly. You must monitor the remaining plants in search of Fusarium symptoms and try to treat the substrate with Trichoderma.

There are several considerations that are important to take into account to avoid their development.

Humidity and Temperature Control

As with any other fungus, fusarium will develop when the environment is humid and warm. Therefore, it is going to be practically appearing if in our crop we carry a exhausted control of humidity and temperature.

The best way to control is to monitor the crop with a hygrometer. If this indicates that the humidity is high, we will use a dehumidifier to maintain correct levels.

As plants need less moisture as they develop and bloom, it is essential to control the growing room regularly.

Acid soils (low pH) poor in nitrogen and rich in potassium

Fungi will grow better on nitrogen-poor acid soils. Plants have less defenses against pests and diseases.

Fungicides for the Fosarium

Use fungicide products, either in the irrigation water or by foliar application as a preventive measure.

Trichoderma

One of the best methods to prevent Fusarium is by applying a product based on Trichoderma. It is effective, but it should be applied in each transplant to ensure that it is present throughout the crop. You should not use fungicides or chemicals, since you will eliminate the trichodermas.

Bioponic Mix by GHE

Green House Powder Feeding Enhancer

Streptomyces griseoviridis, competes for the substrate and the rhizosphere, and produces streptomycin, bacterial toxic antibiotic, can be used together with trichodermas

Bactofil

The Bacillus subtilis strain QST 713, also effective against powdery mildew and botrytis, is a highly positive bacterium that produces secondary metabolites with anti fungal properties such as Iturin A and surfactin. It can be applied together with tricodermas. Bactofil

Avoid over watering

In addition to cutting off the supply of oxygen to the roots, excessive watering also promotes the growth of any fungus. Then, it is essential that you water the plants correctly to avoid these common problems.

Clean the Farming Room

You should try to keep clean the growing room, greenhouse or outside garden.

Get rid of the old leaves of the ground. since the spores can also germinate in dead plant matter. Also avoid water deposits or standing water.

If you are going to reuse the pots from one crop to another, wash them thoroughly with bleach and rinse well with plenty of water before using them. We will have to clean all the instruments like mowers, irrigation tanks, etc. Maintain the hygiene of the walls and floors of the indoor crop.

Sterilize gardening tools

Diseases are often spread from one place to another by the use of garden tools that have been in contact with fungi.

Therefore, be sure to clean and sterilize all the utensils you use, as well as the gardening gloves and the irrigation hose if you use it. When it comes to stopping fusarium, we need to cover all the bases.

Look for signs of infection

Controlling the status of marijuana plants is an important part of caring for them.

Without it, we will not know if our plants are suffering from a Fusarium infestation. But, what does an infected plant look like? As mentioned, the two main symptoms are wilting and root rot depending on the type of weed.

Change your clothes to enter the Cultivation Room

In indoor crops, you must change your clothes and shoes before entering. You should also wash your hands very well before touching the plants. Hygiene is essential.

Stop the infection

While it may be useless to treat infected plants, we can try to save healthy ones if we move fast.

The first thing we must do is get rid of the infected plants. We can try to apply trichodermas to healthy ones and some product for fungi (like neem extract). However, it is very likely that in the end the virus will also spread to healthy ones and have to eliminate them. Porello, it is best to start with a new crop.
