DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to certain tricyclic heterocycles, their N-oxides, 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 consumers. 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 and environmentally safe.
SUMMARY OF THE INVENTION
This invention is directed to compounds of Formula I including all geometric and stereoisomers, N-oxides, and agriculturally suitable salts thereof, agricultural compositions containing them and their use for controlling undesirable vegetation: ##STR2## X is O, S(O).sub.r, N(C.sub.1 -C.sub.2 alkyl) or CH.sub.2 optionally substituted with 1-2 C.sub.1 -C.sub.2 alkyl; Y together with the carbons to which it is attached form a phenyl ring or a fused five or six-membered heterocyclic ring, which may be fully aromatic or partially or fully saturated, containing 1 to 3 heteroatoms independently selected from the group nitrogen, oxygen, and sulfur, provided that the heterocyclic ring contains no more than 2 oxygens and no more than 2 sulfurs, and the ring is optionally substituted with one to three groups independently selected from the group C.sub.1 -C.sub.6 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, aminosulfonyl, C.sub.1 -C.sub.2 alkylaminosulfonyl, C.sub.2 -C.sub.4 dialkylaminosulfonyl, NR.sup.15 R.sup.16, C.sub.2 -C.sub.6 alkoxyalkyl, C.sub.2 -C.sub.6 alkoxycarbonyl, C.sub.2 -C.sub.6 alkylcarbonyl, halogen, cyano, nitro, phenyl optionally substituted with C.sub.1 -C.sub.3 alkyl, halogen, cyano or nitro, and pyridyl optionally substituted with C.sub.1 -C.sub.3 alkyl, halogen, cyano or nitro, provided that when a nitrogen atom of the fused heterocyclic ring is substituted, then the nitrogen substituent is other than halogen;
Z is selected from the group --CH.sub.2 CH.sub.2 CH.sub.2 --, --OCH.sub.2 CH.sub.2 --, --O--CH.dbd.CH--, --NR.sup.13 CH.sub.2 CH.sub.2 --, --NR.sup.13 CH.dbd.CH--, --N.dbd.CHCH.sub.2 --, --OCH.sub.2 O--, --NR.sup.13 CH.sub.2 NR.sup.13 --, --N.dbd.CHNR.sup.13 --, --CH.sub.2 OCH.sub.2 --, --CH.sub.2 NR.sup.13 CH.sub.2 --, --CH.sub.2 S(O).sub.r CH.sub.2 --, --CH.sub.2 C(O)CH.sub.2 --, --CH.dbd.NCH.sub.2 --, --CH.sub.2 CH.sub.2 --, --OCH.sub.2 --, --SCH.sub.2 --, and --NR.sup.13 CH.sub.2 --, each group optionally substituted with one to four R.sup.5, and the directionality of the Z linkage is defined such that the moiety depicted on the left side of the linkage is bonded to the carbonyl carbon of Q-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, aminosulfonyl, C.sub.1 -C.sub.2 alkylaminosulfonyl, C.sub.2 -C.sub.4 dialkylaminosulfonyl, 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, halogen or NR.sup.15 R.sup.16 ; or R.sup.4 is phenylthio, phenylsulfonyl or --SCH.sub.2 C(O)Ph, each optionally substituted with C.sub.1 -C.sub.3 alkyl, halogen, cyano or nitro; alkenyl, C.sub.3 -C.sub.6 alkynyl
