What is this on Rosemary?
I've looked at other forums and I believe it to be either sclerotia or psuedonomas or a blight infection. (Based off another forum and another website.)This is the first time I've experienced this and we've owned this plant for years. Could a pesticide work on it? It's not on all of the plant but it's turned some lower branches brown. It's in a raised bed near other plants so could it spread to other plants? (Near it I've planted Spring onions, chives, carrots and beetroot.) Also, there is a new Rosemary plant next to it but it doesn't seem to have any of that on it. Any help is appreciated.
