Abstract

Although the first or second clonal cuttings of heat-treated sugar cane were widely used for seed, differences were not detected among crop years or locations in the incidence of ratoon stunting disease. Sugar cane mosaic virus (SCMV) disease was widespread in all areas surveyed; however, the plant cane crop had a lower incidence of SCMV than the first or the second ratoon crop. The estimated cane yield was increased approximately 19.4 t/ha by heat treatment during the 2-year survey period. The management system used to control the Sugar cane borer (SCB), Diatraea saccharalis (F.), was effective regardless of the crop year or area surveyed. Season-long SCB control was achieved by the use of two (1981) or three (1982) properly timed applications of insecticide and the use of a SCB moderately resistant variety resulting in an average of 6-9% bored Sugar cane internodes. Poor weed management, particularly with johnsongrass (Sorghum halepense (L.) Pers.), accounted for much of the reduction in cane yield (P < 0.01); the estimated yields of the second ratoon crop were substantially altered, particularly those of farms surveyed in the Bayou Lafourche area. © 1987, Cambridge University Press.
