Abstract
SUMMARY Organophosphorus sprays applied to crops of potatoes in eastern England in 1969–73 inclusive controlled aphid numbers and increased yield by at least 10 per cent when populations of aphids reached 500 or more per 100 leaves on untreated plants. They also tended to reduce the severity of potato blight at sites heavily infected before mid‐September. Fungicide sprays (mostly mancozeb or maneb) were extremely successful in controlling blight on the foliage and increased yield of ware tubers by 12–24 per cent at sites where blight became severe, the larger increase occurring when blight became severe by the end of August. Blight sprays also appeared to increase the number of aphids present in mid and late July on plots receiving aphicides.
