T h e effective use of concentrated 2,4-D amine solutions for weed control h a s been made difficult, and sometimes impossible, in many agricultural regions because of hard water conditions. But now the precipitation of undesirable salts (caused by the dilution o f concentrated 2,4-D amine solutions with "hard" water) can be avoided. A new Pittsburgh chemical . . . I M I N O L - D . . . when incorporated in 2,4-D concentrates at the time of formulation, not only prevents nozzleclogging precipitates b u t also increases the wettability and effectiveness o f the spray. iPrecipitation protection lasts for an adequate period after hard water dilution. Since many of the richest agricultural areas in the country have water classified as hard or very hard, the introduction of Pittsburgh I M I N O L - D is a development of significant importance to herbicidal spray manufacturers.
