Abstract:
Novel amine salts of substituted N-phosphonomethylureas are disclosed herein, having the formula in which R, R', and R'' are independently C1-C4 alkyl; a is 1 or 2 and b is 2 or 3, such that the sum of a and b is 4; and c is 1 or 2 and d is 0 or 1, such that the sum of c and d is 2. The compounds are useful in regulating the natural growth or development of plants.
Abstract:
A compound characterised in that it consists essentially of a phosphonium cation and a glycylmethyl phosphonate anion is disclosed. More particularly, such compounds correspond to the following general formula (I): wherein
R 1 , R 2 , R 3 and R 4 independently represent C 1 -C 10 alkyl, optionally substituted benzyl or optionally substituted phenyl, the substituents being selected from halogen C 1 -C 4 alkoxy and C 1 -C 4 alkyl, provided that at least one or R 1 , R 2 . R 3 and R 4 represents optionally substituted benzyl or substituted phenyl; or to the following general formula (II): wherein R 1 , R 2 , R 3 and R 4 independently represent C 1 -C 10 alkyl or phenyl.
Sucn compounds may be used as herbicides and plant growth regulants.
Abstract:
Trialkylsulfonium salts of N-phosphonomethylglycine having the formula in which R represents C 1 -C 3 alkyl and n is zero or one are useful in regulating the natural growth or development of plants and as herbicides, and can be prepared from N-phosphonomethylglycine directly or by in a two stage reaction with a trialkylsulfonium or sulfoxonium halide.
Abstract:
Novel tri-mixed alkylsulfonium salts of N-phosphonomethylglycine are disclosed herein, having the formula in which R 1 , R 2 , and R 3 represent C 1 -C 5 alkyl and n is zero or one, wherein no more than two of R 1 , R 2 or R 3 are identical. The compounds are useful in regulating the natural growth or development of plants and as herbicides.
Abstract:
Trialkylsulfonium salts of N-phosphonomethylglycine having the formula in which R represents C 1 -C 3 alkyl and n is zero or one are useful in regulating the natural growth or development of plants such as herbicides. Preferably R is C 2 H 5 and n is zero.

Abstract:
Nolvel amine salts of substituted phosphonomethylureas having the formula in which
R,R' and R" are independently C 1 -C 4 alkyl; a is 1 or2 and b is2 or3, such thatthe sum of a and b is4; and c is 1 or 2 and d is 0 or 1, such that the sum of c and d is 2.
These compounds are useful in regulating the natural growth or development of plants. They may be prepared by reacting the appropriate amine ReNHtb, where b' is 1 or2, with an appropriate phosphonic acid. A rate of application of 0.11 to 22 kg/ ha is suitable. For application the compounds may be formulated with an inert carrier or diluent A preferred compound is the mono(diisopropylamine) salt of N,N-dimethyl- N-carboethoxymethyl-N'-phosphonomethylurea.
