Hi friends!
We want to write today about this other fungus...

289895

Botrytis is a fungus that usually attacks on stems, leaves and buds (in bloom). This pest produces rottenness in attacked areas.
It is usually called grey mould or gray mold, as it forms a sort of gray fuzz.
His prolific conditions for their development are mild temperatures and high humidity.
If these conditions are met the gray mold will spread quickly and end with the plant quickly.
In outdoor crops usually happens in spring because of rainfall during that season, causing both, moderate temperatures and humidity, generating the right climate for the fungus.
More sativa varieties are the most "appreciated" to be attacked by the botrytis.

The typical symptom is a characteristic dark gray fluffy mycelium of the affected area. Affected parties rot. This disease infects entering through wounds caused by insects, hail or chafing.

Interestingly, if you see any of these symptoms:
- Sheets of dried buds.
- A gray spot bud progresses downward.
- The buzz is "undone" when touched.
- In cuttings, see if the buried part of the stem is "rotten."

DAMAGE:

- Destroy them like rotten buds.
- Kill the harvest in just one week if you act quickly.
- The cuttings and young plants die suddenly.


PREVENTION:

Avoid injuries on the plant, if the plant has any you must use a scar product.
Be especially careful with clones. Use a scar product.
Avoid humidity increases and have good ventilation in your crop.
Good drainage in the pot is essential.
Do not reuse the same land where you had a plant affected by botrytis, the fungus can remain in the soil and infect the new.



CONTROL:

If you have a sick plant delete it or cut affected parts for prevent spreading.


I HAVE BOTRYTIS, WHAT CAN I DO?:

We must say that there are also organic remedies, but in this case is already complicated combat with chemical fungicides, its effects are smaller and may not give good results.


ORGANIC REMEDIES:

Absinthe Broth: For this preparation first we must know if we have fresh wormwood or possibly has already been dried.
If itâ??s fresh, the ratio will be 150 grams per liter. If the wormwood has been dried beforehand, the proportion is 15 grams per liter.
Immerse the stems and leaves of the plant (depending on the ratio explained above) and let it go over for 15 days, after which, spray on the plant.
Nettle soup: Cut the root, and will use the rest of the plant at a rate of 100 grams per liter of water if the plant is fresh. In your case, if it has been dried, the proportion will be 20 grams per liter if it has been dried. We leave 15 days to rest and apply on the affected plant.
We advise these ecological and preventive remedies, because once caught the pest by the plant, these treatments actually dictate far from effective.


SYSTEMIC FUNGICIDES:

If the attack is caught early, you can treat with fungicides such as:
Fosetyl-A1, Oxadixyl, Benomyl or Vinclozolin.

Almost any commercial product has these components:
- Euparen from Bayer.
- Multipurpose Fungicide, of Masso.
- Total Multipurpose Fungicide, Flower.
- Multipurpose Fungicide Compo.



BIOLOGICAL FUNGICIDES:

A biological fungicide specific for this type of fungus is the Rot Stop, the biological being can be used both in growth and flowering.



Hope this info will be useful for you.
Have a great day!

Peace.
