Yield losses in sugarcane caused by ratoon stunting disease were observed for seven of eight cultivars tested in four to six crop cycles of 3-yr plantings. In the seven cultivars, average 3-yr losses ranged from 29 to 60 t/ha; sugar losses ranged from 2,67 to 7,369 kg/ha. Losses tented to increase with the number of years a planting was cropped. Cane losses averaged 14% in the first-year crop and increased to 27% in the third-year (second-ratoon) crop. For a given cultivar, the magnitude of losses varied among plantings; however, the planting × disease treatment interaction was not significant (...)
