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:
An inherently pliable polymeric marking film comprises a film component containing an internally plasticized vinyl chloride copolymer resin, a layer of pressure sensitive adhesive and, in preferred embodiments, a release coated protective liner. In certain embodiments, the polymeric marking film is destructible. The marking film has a small degree of shrinkage, shows exceptional conformability to irregular surfaces and has permanence of mechanical properties upon exposure to elevated temperatures.
Abstract:
The present invention relates to blends of: (1) a vinyl chloride polymer; and (2) a thermoplastic graft copolymer composition comprising (a) a resinous polymer of monoethylenically unsaturated, non-chlorinated, resin-forming material and (b) a rubbery polymer of two different linear alpha-monoolefins, one of which is preferably ethylene and the other of which is a higher alpha-monoolefin having 3 to 16 carbon atoms, and a copolymerizable non-conjugated diene.
Abstract:
Compounds having the formula in which R is selected from the group consisting of hydrogen and lower alkyl having 1-4 carbon atoms, inclusive, are useful as antidotes for thiocarbamate herbicides, and may be applied on their own or in admixture with the herbicide. Seeds may be coated with the antidotes.
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 translation:具有下式的N- phosphonomethylglycines的三烷基锍盐... ...其中R darstellt C1-C3烷基和n是零或一个是在调节植物的自然生长或发育的有用:例如除草剂。 优选地,R是C 2 H 5,n是零。
Abstract:
Alkyl and alkoxyalkyl substituted benzenes having the formula in which R is C 1 -C 5 alkyl, C 1 -C 4 alkoxy, methylenedioxy or hydrogen and R' is C 2 -C 20 alkyl or C 2 -C 20 alkoxyalkyl are prepared from corresponding benzyl halides by a three-step process of cyanation, alkylation, and decyanation.
