This fungus lives in the soil and feeds on waste from other organisms. The name for this disease is fusarium, and then tell you how to eradicate it.
What is the fusarium fungus?
Fusarium fungus comes from the family of nectriáceas and is actually in a reasonably broad genre that encompasses different types of filamentous fungi that inhabit the substrate. Generally, these types of fungi are saprophytes, meaning that they depend on the remains of various organisms to feed themselves. This means acting parasitically, colonizing cannabis, feeding on the plant, and causing the same sick and eventually die.
What happens when the fusarium fungus attacks a plant?
Fusarium fungus attacks the plant pot from the floor, colonizándola by xylem ducts, preventing the flow of sap. If we made a passing resemblance to the human body, this fungus taponaría the veins of our organization, blocking blood flow.
This fungus weakens the plant and the sick, causing his death since it has not yet developed any effective product to combat it. So the best you can do if your plants are infected is to remove all plants with the fungus.
Blocking the sap causes yellowing and wilting of leaves and stems, accompanied by necrosis. Several factors may contribute to the contamination and spread of the fungus. If you use seeds, soil, tools or cultivars contaminated by fusarium, no doubt, you will translate the fungus to other plants s breeding conditions are favorable: high humidity, low light, acidic soils and deficient in nitrogen and high in potassium, temperatures between 12 and 28 ° C.
It is essential to note that this fungus has conservation mechanisms that allow it to continue inactivity in the substrate up to 6 years so that plants have died by this fungus will serve to contaminate others who are around him.
- Symptoms of fusarium
- Rottenness and lignification of stems
- Yellowing leaves
- root rot
- The attack usually progresses from the bottom of the pot to the top.
How to prevent and control the fungus?
As we said earlier, there is currently no treatment that is effective for infected plants fusarium fungus. Therefore the only and best option is prevention. This means that to avoid having to disinfect all tools you use and always buy a good quality substrate.
Scatters the risks and try to keep it below 30 ° C. Many cannabis growers usually add to the substrate a beneficial fungus called Trichoderma. However, if your plant is affected by fusarium, it is advisable to get rid of it as soon as possible, so they do not harm healthy plants.
Carefully monitors the remaining plants for symptoms of fusarium fungus and treats the substrate with Trichoderma fungi that colonize and prevent fusarium penetrate the soil. A tip: before planting marijuana seeds, apply a fungicide naturally based green nettle or horsetail.
