WHO CAUSES IT?
Botrytis cinerea is a filamentous fungus that causes the disease known as gray rot in a wide variety of plants, including crops, flowers and fruit trees. It is a very destructive pathogen that can attack healthy and injured plant tissues, both in field and greenhouse conditions. This fungus spreads rapidly in cool, humid environments, and is capable of surviving for long periods in plant debris, soil, and in storage conditions.

SYMPTOMS
On grapevines, Botrytis cinerea can cause a disease known as grape gray rot. Symptoms include the formation of watery Taches on the surface of the berries, which are subsequently covered with grayish mold. As the infection progresses, the berries become soft, wrinkled and eventually disintegrate, leading to loss of harvest and wine quality.
TEMPERATURE AND HUMIDITY
15°C - 20°C
90% - 100%
TRANSMISSION ROUTES
Air, rainwater, direct contact with infected plants, contaminated soil, contaminated growing tools, infected plant material, and spread through spores produced by the fungus.

Recommendations
To prevent and control gray rot caused by Botrytis cinerea in grapevines, it is essential to implement a series of integrated management measures. These may include appropriate pruning to improve air circulation and reduce humidity, weed control and removal of crop debris. Additionally, preventative fungicides can be applied in a timely manner, especially during periods of high humidity and rain.
