Pests Of Sugarcane And Their Control PDF Download

Excerpt from Pests of Sugarcane and Their Control Borer attacks on sugarcane may cause any of the following types of damage: (1) Dead hearts in young plants, (2) dead tops in older plants, (3) broken-over stalks, (4) loss in weight and sucrose, and (5) injury to seed cane. Borer injury is not so easily recognized in old plants as in young ones unless the infestation is heavy enough to cause many dead tops and broken stalks. Some borers, as they tunnel up and down the stalk, gnaw their way out through the hard rind and re-enter at another place. Usually the leaf sheaths must be stripped off to detect borer entrance and exit holes and the sawdustlike frass pushed out of borer tunnels.
