Claims
- 1. A method for inhibiting the growth of undesirable plants which comprises applying to the plant system a herbicidally effective amount of a compound having the formula ##STR9## wherein X and Y are independently selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, trifluoromethyl, halogen, cyano and nitro; n is zero or one provided than when n is zero, Z is selected from the group consisting of chloro and NR.sub.1 R.sub.2 wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen and lower alkyl; when n is one, Z is selected from the group consisting of alkyl having up to 12 carbon atoms inclusive, haloalkyl, benzyl, lower alkoxy lower alkyl, allyl, monochlorinated allyl, dichlorinated allyl, ##STR10## and agriculturally acceptable cations; wherein R.sub.1 and R.sub.2 are as previously defined, R.sub.3 is hydrogen or methyl and R.sub.4 is lower alkyl.
- 2. A method according to claim 1 wherein Z is alkyl having up to 12 carbon atoms inclusive.
- 3. A method according to claim 1 wherein X is trifluoromethyl and Y is hydrogen or trifluoromethyl.
- 4. A method according to claim 3 wherein X is in the 3-position.
- 5. A method according to claim 4 wherein Y is hydrogen.
- 6. A method according to claim 1 which comprises applying said compound to the soil before the emergence of the undesirable plants.
