Stem cuttings from a prostrate clone of Cephalotaxus harringtonia (Forbes) K. Koch (Japanese plum yew) were taken monthly from Sept. 1994 through Aug. 1995, treated with K-IBA at 0 or 10,000 mg·liter–1, placed in a greenhouse under intermittent mist, and evaluated after 16 weeks. Cuttings taken from December to February and treated with K-IBA averaged 85% rooting, 10 roots per cutting, and a total root length of 35 cm. The next highest rooting percentages were for cuttings taken from March to May; poorest rooting occurred for cuttings taken from June to August and September to November, regardless of K-IBA application. Chemical name used: K-indole-3-butyric acid (K-IBA).

Apple (Malus domestica Borkh.) leaves were sprayed to runoff using a selection of pesticides, and subsequent spray retention was evaluated by weight. Timing, cultivar, leaf surface, and leaf type significantly influenced spray retention. Spray retention correlated significantly and positively with leaf hair density. The importance of these differences is considered in relation to the possible efficiency of the pesticide application process in apple orchards.
