Dear Rakesh , On zooming, it does look like scale insects. I have seen scale insects on pepper vines that are much smaller and are difficult to dislodge. However, I have been able to successfully treat it with an emulsion of neem oil and extracts of gliricidia leaves and wild camphor leaves I am not sure about the name. In common parlance they call it malaria chappu in Malayalam. we need to spray the plant a couple of times and then it is very easily dislodged. In fact they die on the vines and then there is no need to dislodge. Regards Yazdy Palia.
