Don't be a blighter, with main crop planting well underway, check old potato dumps and prevent any growth on them. Most outbreaks of potato blight can be traced back to someone's long forgotten potato dump.

For low risk crops, the first blight fungicide should be applied at the high-risk warning or when the leaves begin to meet along the drills, whichever is sooner.

A key factor in successfully controlling blight with fungicides is to start programmes early enough. In some situations, fungicide needs to be applied before the crop meets along the rows, e.g. very susceptible varieties, locations that experience suggests are prone to early infection, crops grown from seed stocks that contained blighted tubers.
