Abstract:
Compounds having the formula in which R is chloro, fluoro, bromo, methyl, methoxy or methylthio, and R 1 and R 2 are each C 1 -C 4 alkyl have herbicidal activity. The compounds may exist as optical isomers.
Abstract:
Certain haloalkylcarbonylamino-1,3-dioxane herbicide antidotes corresponding to the following general formula: wherein
R represents chloro-, bromo- or iodo- C 1 -C 4 alkyl; R, represents hydrogen, C 1 -C 4 alkyl, C 2 -C 4 alkenyl or phenyl; R 2 represents hydrogen or C 1 -C 4 alkyl; R 3 represents hydrogen or C 1 -C 4 alkyl; and R 4 represents hydrogen or nitrophenyl; provided that one of R 3 and R 4 represents hydrogen; are disclosed, as is the production thereof.
Such compounds may be formulated with inert diluents or carriers and/or adjuvants or with herbicides, in particular thiocarbamates or acetanilides. The use of such compounds counteracts crop damage caused by herbicides and hence provides a method of establishing herbicidal selectivity.
Abstract:
"N-cyano and N-alkynyl-2- (substituted phenoxy) butyramides and the use thereof as miidewicides" A compound corresponding to the following general formula: wherein O represents when Q represents X represents chlorine, bromine, thiocyano or methyl; and R represents methyl, ethyl or methoxymethyl; and when 0 represents X represents bromine or methyl; and R' represents hydrogen or methyl. The use of such compounds for controlling mildew is also disclosed.

Abstract:
A compound characterised in that it corresponds to the following general formula: wherein
R represents C 1 -C 4 haloalkyl; R 1 represents hydrogen or C 1 -C 4 alkyl; and R 2 represents C 2 -C 8 cyanoalkyl, C 5 -C 12 cyanoalkylcycloalkyl, C 5 -C 12 cyanocycloalkyl, C 3 -C 6 cyanoalkylalkoxy or cyanobenzyl; provided that, when R 2 represents cyanoalkyl, R repres- entsdibromoalkyl; is disclosed.
The above compounds may be prepared by reacting an appropriate nitrile amine or salt thereof with an appropriate halogenated acid chloride. The use of the above compounds reduces the injury to desired vegetation caused by herbicides, more particularly thiocarbamates and haloacetanilides. Compositions comprising such antidotes and such herbicides are also disclosed.
Abstract:
Alkylphosphonium salts of N-phosphonomethylglycine having the formula wherein R 1 , R 2 , R 3 and R 4 are the same and are selected from the group consisting of saturated or unsaturated alkyl groups having from 2 to 5 carbon atoms, and their use as herbicides.
