My potted cayenne peppers have had problems with pests for about a year and a half. Does any one recognize it and know how to deal with it?
The plants have been standing on a glazed balcony during summer, the older ones have been overwintering indoors.
The soil is a mixture of potting soil and compost.
When I planted them I added some spoons of leftover tomato fertilizer (7-3-10)
I am located in northern scandinavia.
I have so far treated it without success by:
- Removing any damaged leaves.
- Spraying/washing leaves and stems with dishsoap diluted in water.
Update: I have sprayed the plants with neem according to stormys answer and have not observed any new damage to the leaves so far.
Update2: After researching this a bit more I believe the pests may actually be (chilli) thrips, rather than whitefly as the accepted answer says. Compare this image to my closeup photograph. I will leave the answer accepted since the neem seems to be effective against them as well, but I might write up a new answer in spring depending on how it works out.
