Ketodiacid compounds that inhibit nematode egg hatchingIowa State University Patents
AbstractA method for inhibiting hatching of soybean cyst nematode eggs is provided comprising contacting said eggs with an effective inhibitory amount of a compound of formula (I): ##STR1## wherein R.sup.1 is H or OH, R.sup.2 is H or OH, R.sup.3 is H or (C.sub.1 -C.sub.4)alkyl, R.sup.4 is H or (C.sub.1 -C.sub.4)alkyl, R.sup.5 and R.sup.6 are individually H, (C.sub.1 -C.sub.5)alkyl, C.sub.3 -C.sub.6 (cycloalkyl)alkyl, C.sub.5 -C.sub.7 (cycloalkenyl)alkyl, (C.sub.6 -C.sub.12)aryl, (C.sub.7 -C.sub.12)aralkyl, trans(C.sub.4 -C.sub.5)alkenyl, allyl or furan-2-ylalkyl or together are (C.sub.2 -C.sub.5)alkylene, or (C.sub.3 -C.sub.5)alkylidene or 1,2-phenylene, optionally substituted by OH, O(C.sub.1 -C.sub.3)alkyl, SH, phenyl or N(R.sup.7)(R.sup.8), wherein R.sup.7 and R.sup.8 are individually H, (C.sub.1 -C.sub.3)alkyl or phenyl; R.sup.9 =H or (C.sub.1 -C.sub.4)alkyl, n is 0 or 1 and wherein the bond represented by --- is present when n=0 or absent when n=1; or an agronomically-acceptable salt thereof.
