Herbicidal composition comprising a liquid thiocarbamate herbicide, a

A substituted aryloxyurea of the formula: ##STR1## wherein Ar represents ##STR2## in which X.sup.7 represents a hydrogen atom, a halogen atom, a cyano group, a lower alkoxy group or a trifluoromethyl group, and

Substituted pyridyloxyureas and use thereof as herbicides

A high concentration herbicide formulation comprising (1) a herbicidally active thiolcarbamate of the following formula I which is liquid at room temperature, (2) at least one nonionic surfactant of the following formula II and (3) an anionic surfactant of the following formula III: ##STR1## wherein R.sup.1 is an alkyl group having from 1 to 3 carbon atoms, a phenyl group or a halogen-substituted phenyl group, R.sup.2 is an alkyl group having from 1 to 5 carbon atoms, and R.sup.3 is an alkyl group having from 1 to 5 carbon atoms, provided that R.sup.2 and R.sup.3 may form a ring; ##STR2## wherein R.sup.4 is ##STR3## wherein R.sup.5 is a hydrogen atom or a methyl group, m is an integer of from 1 to 3, x is an integer of at least 10, y is an integer of from 0 to 10, provided that x+y is within a range of from 10 to 30, A is an oxyethylene group, and B is an oxypropylene group, provided that the addition form of A and B may be a block-form or a random-form; and ##STR4## wherein R.sup.6 is an alkyl group having from 9 to 15 carbon atoms, M is an alkali metal or an alkaline earth metal, and n is the number of metal ions.

High concentration herbicide formulation

Novel substituted aryloxyureas, processes for their production, and herbicides comprising them as active ingredients are provided. The substituted aryloxyureas exhibit an excellent herbicidal efficacy against weeds when applied, for example, to the weeds in a wide range of period from a preemergence stage to a growth stage. The substituted aryloxyureas of the invention have the excellent advantage of maintaining high safety on crops or crop plants in spite of their herbicidal efficacy.

Substituted aryloxyureas, processes for production thereof and uses

As a herbicide, a 9-phenylimino-8-thia-1,6-diazabicyclo [4.3.0]nonane-7-one derivative having the formula: ##STR1## wherein each of X and Y is hydrogen or halogen, and Z is ##STR2## wherein R is hydrogen or alkyl, and R.sup.1 is alkyl, cycloalkyl, or alkoxyalkyl, provided that when R is methyl, R.sup.1 is alkoxyalkyl or Y and Z together form ##STR3## bonded to the phenyl ring, wherein R.sup.2 in hydrogen or C.sub.1 -C.sub.6 alkyl and R.sup.3 is C.sub.1 -C.sub.6 alkyl, C.sub.3 -C.sub.5 alkenyl, or C.sub.3 -C.sub.5 -alkynyl.

Thiadiazabicyclononane derivatives and herbicidal composition

As a herbicide, a 9-phenylimino-8-thia-1,6-diazabicyclo [4.3.0]nonane-7-one derivative having the formula: ##STR1## wherein each of X and Y is hydrogen or halogen, and Z is ##STR2## wherein R.sup.1 is alkyl or cycloalkyl, or --COOR.sup.2 wherein R.sup.2 is alkyl.

Thiadiazabicyclononane derivatives and herbicidal compositions

As a herbicide 9-phenylimino-8-thia-1,6-diazabicyclo[4.3.0]nonane-7-(one or thione) compound having the formula: ##STR1## wherein Y represents halogen, hydroxyl, alkyl, alkoxy which may be substituted by halogen, alkenyloxy, alkynyloxy, phenoxy, cycloalkyloxy, alkoxycarbonylalkyloxy alkoxycarbonylalkenyloxy, alkythiocarbonylalkyloxy, alkynyloxycarbonylalkyloxy, benzyloxycarbonylalkyloxy, trifluoromethyl, benzyloxy, alkenyl, cyanoalkyl, alkylcarbamoyloxy, benzyl, alkoxyalkyl, alkynyloxyalkyl, cycloalkylmethyloxy, alkoxyalkyloxy, phenethyloxy, cycloalkyloxycarbonylalkyloxy, pyrrolidinocarbonyl, phenylcarbonyl, ##STR2## n is an integer of from 0 to 3; and X is oxygen or sulfur.
