DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to certain ketals and spirocycles, their agriculturally suitable salts and compositions, and methods of their use for controlling undesirable vegetation.
The control of undesired vegetation is extremely important in achieving high crop efficiency. Achievement of selective control of the growth of weeds especially in such useful crops as rice, soybean, sugar beet, corn (maize), potato, wheat, barley, tomato and plantation crops, among others, is very desirable. Unchecked weed growth in such useful crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of undesired vegetation in noncrop areas is also important. Many products are commercially available for these purposes, but the need continues for new compounds which are more effective, less costly, less toxic, environmentally safer or have different modes of action.
EP 293,261 discloses heterocycles of Formula i as herbicides: ##STR2## wherein X, X.sup.1 and X.sup.2 are independently O or S; substituted by one or more groups selected from oxo, mercapto, halo, nitro, cyano, amino, mono- or dialkylamino, amido, alkyl, alkenyl, alkynyl, cycloalkyl, haloalkyl, haloalkoxy, aryl, hydroxy, alkoxy, alkoxycarbonyl, alkylcarbonyl, mono- or dialkylcarbamoyl, alkylthio, alkylsulfinyl, alkylsulfonyl, sufonamido, alkylcarbonyloxy, alkylcarbonylamino or heterocyclyl; and
The ketals and spirocycles of the present invention are not disclosed in this reference.
SUMMARY OF THE INVENTION
This invention is directed to compounds of Formula I including all geometric and stereoisomers, agriculturally suitable salts thereof, agricultural compositions containing them and their use for controlling undesirable vegetation: ##STR3## wherein Q is ##STR4## R.sup.1 and R.sup.2 are each independently C.sub.1 -C.sub.6 alkoxy, C.sub.2 -C.sub.6 haloalkoxy, C.sub.1 -C.sub.6 alkylthio or C.sub.2 -C.sub.6 haloalkylthio; or R.sup.1 and R.sup.2 are taken together to form --X.sup.1 --(CH.sub.2).sub.r --X.sup.2 --, --(CH.sub.2).sub.s --X.sup.3 --, --(CH.sub.2).sub.t --X.sup.3 --CH.sub.2 --, --(CH.sub.2).sub.v --X.sup.3 --CH.sub.2 CH.sub.2 -- or --(CH.sub.2).sub.w --, each group optionally substituted with at least one member selected from 1-6 halogen, 1-6 CH.sub.3 and one C.sub.1 -C.sub.3 alkoxy; or R.sup.1 and R.sup.2 are taken together to form --O--N(C.sub.1 -C.sub.3 alkyl)--CHR.sup.12 --CH.sub.2 -- or --O--N.dbd.CHR.sup.12 --CH.sub.2 --, each group optionally substituted with at least one member selected from 1-2 halogen and 1-2 CH.sub.3 ; or R.sup.1 and R.sup.2 are taken together with the carbon to which they are attached to form C(.dbd.O) or C(.dbd.S); alkyl); C.sub.1 -C.sub.6 haloalkyl, C .sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 haloalkoxy, C.sub.1 -C.sub.6 alkylthio, C.sub.1 -C.sub.6 haloalkylthio, C.sub.1 -C.sub.6 alkylsulfinyl, C.sub.1 -C.sub.6 haloalkylsulfinyl, C.sub.1 -C.sub.6 alkylsulfonyl, C.sub.1 -C.sub.6 haloalkylsulfonyl, halogen, cyano or nitro; haloalkylthio, C.sub.1 -C.sub.6 alkylsulfinyl, C.sub.1 -C.sub.6 haloalkylsulfinyl, C.sub.1 -C.sub.6 alkylsulfonyl, C.sub.1 -C.sub.6 haloalkylsulfonyl, cyano, cyanato, thiocyanato or halogen; alkoxy, C.sub.1 -C.sub.3 alkylthio or halogen; or when two R.sup.7 are attached to the same carbon atom, then said R.sup.7 pair can be taken together to form --OCH.sub.2 CH.sub.2 O--, --OCH.sub.2 CH.sub.2 CH.sub.2 O--, --SCH.sub.2 CH.sub.2 S-- or --SCH.sub.2 CH.sub.2 CH.sub.2 S--, each group optionally substituted with 1-4 CH.sub.3 ; -C.sub.6 alkoxyalkyl, formyl, C.sub.2 -C.sub.6 alkylcarbonyl, C.sub.2 -C.sub.6 alkoxycarbonyl, C.sub.2 -C.sub.6 alkylaminocarbonyl, C.sub.3 -C.sub.7 dialkylaminocarbonyl, C.sub.1 -C.sub.6 alkylsulfonyl or C.sub.1 -C.sub.6 haloalkylsulfonyl; or R.sup.8 is benzoyl or phenylsulfonyl, each optionally substituted with C.sub.1 -C.sub.3 alkyl, halogen, cyano or nitro; -C.sub.6 alkenyl or C.sub.3 -C.sub.6 alkynyl; or R.sup.9 is phenyl or benzyl, each optionally substituted on the phenyl ring with C.sub.1 -C.sub.3
