Northern Poor Root Syndrome of sugarcane - studies on soil transmission and the effects of various fungicidal, nutritional and agronomic treatments

This paper discusses a series of investigations involving soil sterilisation, soil transmission, nutrient and pH effects, soil physical structure and fungicide applications, and the responses obtained in plant growth and NPRS root symptoms. NPRS symptoms on roots, as they are currently understood, include a soft, flabby rot, small reddish lesions, and poor development of lateral and fine roots. The symptoms are described elsewhere (Egan et at., 1984; Lawrence, 1984; Magarey, 1984).
