  • Ripening of sugarcane by use of certain alcoholic and ethoxylated compounds
    Patent number: 3930840
    Abstract: Sucrose yield of sugarcane is increased by treating sugarcane a few weeks prior to harvest with a ripening agent which is composed essentially of a compound selected from the group consisting of linear alcohols containing from 11 to 15 carbon atoms, polyalkylene glycols and ethoxylated compounds of the general formulaR--O--CH.sub.2 CH.sub.2 O).sub.n Hwherein R is C.sub.8 - C.sub.20 alkyl or ##SPC1##R' being hydrogen or alkyl of 8 to 15 carbon atoms, andn is an integer from 6 to 20, in an amount sufficient to increase sucrose yield.
