The concentration of the essential ingredients for application to a crop by conventional ground methods is preferably within the range of {TAIL ~ 0.001 to 10 percent}, especially 0.005 to 5 percent by weight of the total composition, but more concentrated compositions containing {HEAD ~ up to 20 percent} by weight may be desirable in the case of aerial sprays but with corresponding loss in economy
