Abstract
513,300. Weed-killing compositions. R-KAS, Ltd. Dec. 14, 1937, No. 34548. Void. Convention date, Dec. 16, 1936. [Class 81 (i)] A weed-killing composition comprises (a) growth-killing agents such as arsenic, (b) a wetting medium for the foliage of the plants such as soft soap with emulsifiers and fat solvents such as triethanolamine and trichlorethylene and saponified tar distillates containing cresols or the like and (c) a substance giving visual indication of the application of the mixture such as a dye. The saponified tar distillates, however, may serve for (c) by virtue of the milkiness they impart to the diluted product. Part (a) is preferably made up separately, e.g., from white arsenic and caustic soda and then added to'parts (b) and (c), the whole being relatively concentrated and requiring dilution before application.
