Various chemicals have been used to eradicate weeds. Of these, sodium chlorate has proved to be one of the most effective and has been used extensively both by experimental workers and by farmers. An objection to the use of sodium chlorate has been the residual toxic effect upon farm crops planted after the weeds were eradicated. There are many cases on record where the soil was either sterile for a period after the application of the chlorate, or, if crops grew, the yields were reduced. From experiments that have been made, it is known that the soil is not injured permanently, and that, in general, a year or two between the application of the chlorate and the planting of farm crops is ample time to allow the toxic effects of the chlorate to disappear. In some cases, the toxic effect of fall applications had disappeared by the following spring.
