Pests of Sugar Cane

Abstract

Sugar cane white grub, Clemora smithi: Tests begun in 1947 have shown that benzene hexachloride is not a practical proposition against this pest though it does reduce infestation. The data emphasize the known ability of the important cane M.I34/32 to overcome the grub injury. When the standard of cultivation practice is good the grub apparently causes no loss in yield unless infestation is very high. Quarantined sugar cane: Pestox 3 is used in the quarantine greenhouse at 3 and 6 c.c. of the 60% anhydride (or equivalent doses of other formulations) per drum of cane after the canes have germinated and the foliage is at least 2 ft. high. This renders the juice toxic to Aphis sacchari [Melanaphis sacchari] for apparently the whole duration of the cane generation (about 10 months).
