Abstract:
New m-(3-alkoxyureido and 3-alkoxythioureido)phenyl carbamates wherein at least one valence of the carbamate nitrogen is satisfied by a halogen-substituted lower alkyl group are shown to be selective herbicides.
Abstract:
New meta-3-alkylated ureido or thioureido phenyl carbamates and thiocarbamates wherein at least one valence of the carbamate nitrogen is satisfied by a halogen-substituted lower alkyl group are shown to be selective herbicides.
Abstract:
N-haloacyl oxazolidines mono or dialkylated with C1-12 alkyl groups at the 2-position and with C1-8 alkyl groups in the 4 and 5 positions of the oxazolidine ring have been found to be selective herbicides for the protection of crop plants.
Abstract:
N-haloacyl (2-spirocyclopentyl, 2-spirocyclohexyl and 2spirocycloheptyl) oxazolidines including those substituted at the 4 and 5 positions with lower alkyl groups are selective herbicides for the protection of crop plants including corn, cotton and peanuts.
Abstract:
Certain N-haloacyl (2-spirocycloaliphatic) oxazolidines including those substituted at the 4 and 5 positions with lower alkyl groups have been prepared. Such compounds are selective herbicides especially useful in protecting corn, cotton, peanuts and soybeans.
Abstract:
Novel compositions comprising (a) an inert carrier and (b) a phytocidal quantity of a compound of the formula:
REPRESENTS A NITROGEN-CONTAINING HETEROCYCLIC GROUP, AND N IS AN INTEGER OF FROM 1 TO 3, ARE DESCRIBED. The invention is advantageous in that the compositions exhibit phytocidal properties toward a wide spectrum of plants. Crop plants are not adversely affected by a significant number of the compositions of this invention, which are selective against pest weeds. Other compositions are general phytocides and are useful in controlling plant growth in rightsof-way. WHERE Y is a monovalent hydrocarbon radical containing from 8 to 12 carbon atoms, X is sulfur or oxygen, R is lower alkylene,
