When used as selective or general contact sprays, dinitro-o-sec-butyl phenol compounds decompose too rapidly to create any problem of residual toxicity. Decomposition of dinitro selectives, like many other herbicides, causes considerable stimulation of crop growth. High cost prevents the use of these compounds for soil sterilization. In pre-emergence sprays water-soluble compounds of dinitro-o-sec-butyl phenol are not safe for tender crops, but preliminary tests indicate parent substituted phenols may be used.
