Abstract
Broadleaf weeds, including sicklepod are selectively controlled in soybean fields by applying post-emergently to the plant foliage one of a restricted class of 5-chlorobenzylthio-1,3,4-thiadiazolylurea compounds, for example, 1,1,3-trimethyl-3-(5-p-chlorobenzylthio-1,3,4-thiadiazol-2-yl)urea.
Claims3
The method of selectively controlling broadleaf weeds in soybean fields comprising applying post-emergently to the plants in said fields an effective amount sufficient to kill weeds, including sicklepod but insufficient to cause substantial permanent injury to soybeans, of a compound having the general structural formula ##STR4## in which R is hydrogen or methyl, with the additional provision that when the chloro substituent is in the para position on the benzyl structure, R is methyl.
The method of selectively controlling broadleaf weeds in soybean fields comprising applying post-emergently to the plants in said fields an effective amount, sufficient to kill weeds, including sicklepod, but insufficient to cause substantial permanent injury to soybeans, of a compound having the structural formula ##STR5##
The method of selectively combating weeds in soybean fields comprising applying post-emergently to the plants in said fields an effective amount, sufficient to kill weeds, including sicklepod, but insufficient to cause substantial permanent injury to soybeans, of a compound having the structural formula ##STR6##
