Botrytis A Quick Look!

Most gardeners and growers cringe at the fist site of the dreaded “grey mold” known as Botrytis Cinerea. I do find that that the fungus is synonymous with damp warm conditions. Certain crops are more susceptible that others. Strawberries are the crop that come to mind, but the dreaded fungus can become a nightmare for all growers. So, this fungus is what’s known as a “necrotrophic” . Of course that means that the fungus kills the host to get all the nutrients that it needs.

Botrytis will also effects well known plants grown indoors. Attacking weak plants and dying flowers. Importantly, this fungus plays a big part in the natural growing cycle of nature. So, helping to form an important part in the natural breaking down of natural substances. Unfortunately, when it affects your precious plants it can become a real pest problem.

In my experience, the first signs can be seen on your plants in a damp wet summer! With sun and rain a plenty. Unfortunately this summer (2021) is such a year. The only thing you can do is keep an eye on your crop for the first signs of the dreaded dark spots.

The plant tissue ,usually the leaves will become darker with some soft looking due to the death of the host plants leaves or flowers. Consequently, a fury grey mold will quickly develop on these dark spots.

Spores develop in the air

Unfortunately, the mold is spread from air borne spores. So, affecting plants when the weather starts to warm up in the spring. Structures called condias are formed usually from previous years infected plants. These are air borne and transported through the air so coming into contact with the host plants leaves and other parts of the plants.

If you find that you have the start of an infection then get rid of the plant parts that are infected. The infected plant parts should be burned if possible or taken as far away as possible for disposal.

I must admit though that getting rid of an infection is very difficult and losses will be imminent. This is because when the mold is disturbed then it release clouds of spores onto adjoining plants. Causing even more infection as time goes by.

There are many preparations that claim to prevent botrytis attacks. One that I think worth trying is prevention by using “BAC foliar spray” on your plants to try and help prevent an attack.
