̄ Johnson grass is a serious pest in many places in the southern part of the UnitedStates, and although it can be controlled by heavy grazing and proper cultivation, there are many instances where such methods cannot be used effectively and where a chemical method for its control would be desirable. During the past few years several investigations have been made in which sodium chlorate has been used. as a means of controlling certain noxious weeds and recommendations have been made for the chemical eradication of quack grass (5), 3 bindweed (6), and Canada thistle (~). In order to determine whether or not sodium chlorate could be used alone or in combination with some other salt to c6ntrol or eradicate Johnson grass, a series of experiments were planned to study the effect of rate, method, and time of application of the chlorate on the growth of the grass.
