Abstract
Alkvlnaphthalenes are used as solvents for chlorinated insecticides and herbicides. Johnson, Veomans, and Smith (2) reported that these solvents could cause the death of the apical meristems of chrysanthemums when applied in concentrated solutions or in mechanically or thermallv generated aerosols. Controlling the number of flowers and fruits on a stem is not only of academic interest but of practical importance. Thev are now controlled on chrysanthemums by removing the excess by hand. Research reported in this paper show that HAN,R a petroleum fraction containing a large percentage of alkvlnaphthalenes. can be used to control the number of flowers borne by chrysanthemum plants.
