Black mould on peppers
Kathy N
Hi, Sharon,
How long have you had the plant? How long has the plant been under plastic? It sounds like your pepper has a fungus called Alternaria alternata - which is commonly referred to as Black Mould (exactly what it looks like!). It is common on many fruits and veg, including tomato and pepper. It is usually associated with moisture, particularly from heavy dew, rain and overhead irrigation. Warm, humid weather makes the condition worse since these are the ideal conditions for the fungus to grow. Given that yours is in a plastic covering, I would assume that lack of air circulation and too much moisture within the plastic have made the right conditions for the mould to grow. Perhaps you could remove the plastic or make the opening larger during the day - especially on warm, sunny days, and then close it up (though not completely) at night? Also, you can buy a fungicide at a local garden centre to help get rid of the problem right now but too moist conditions will cause it to grow again.
