Thiazoles and their agricultural compositions

Substituted arylindazoles of the formula: ##STR1## wherein X is CR.sup.14 and R.sup.14 is hydrogen, halogen, haloalkyl, cyano, nitro, alkylthio, alkylsulfonyl, alkylsulfinyl or alkoxy; and substituents R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are as defined in the specification. Use of the compounds as herbicides and methods of making the compounds are also described.

Arylindazoles and their use as herbicides

Process for the preparation of fluoroalkenylthio heterocyclic derivatives

The invention provides novel compounds of formula (I) having nematicidal, insecticidal, acaricidal and fungicidal properties, compositions comprising them and processes and intermediates for their preparation: ##STR1## wherein R.sup.1 is --S(O).sub.n CH.sub.2 CH.sub.2 CH.dbd.CF.sub.2 ;

Pyrimidine derivatives useful as nematicides

The invention provides compounds of formula (I) having nematicidal, insecticidal, acaricidal and fungicidal properties, compositions comprising them and processes and intermediates for their preparation: ##STR1## wherein: X is oxygen or sulphur;

Heterocyclic compounds

This invention relates to substituted aryl indazoles, a process for producing them and their use as herbicides. In particular this invention relates to substituted aryl indazoles of the formula ##STR1## wherein all variables are as defined in the specification.

Pyrazinone derivatives useful as insecticides have the formula (I): ##STR1## wherein A is N or C-R.sup.1 ; R.sup.1 and R.sup.2 are independently selected from hydrogen, halogen, haloalkyl, cyano or nitro; R.sup.3 and R.sup.4 are independently selected from hydrogen, halogen, alkyl or cycloalkyl; R.sup.5 is cyano, halo, nitro, alkoxy, haloalkyl, haloalkoxy or --S(O).sub.n R.sup.10 ; R.sup.6 is halo, cyano, nitro, haloalkyl, haloalkoxy, alkoxycarbonyl or --S(O).sub.n R.sup.10 ; R.sup.7 is hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylthio, haloalkylthio, alkoxycarbonyl, NR.sup.11 R.sup.12 or haloalkyl; R.sup.8 is H, halo, NR.sup.11 R.sup.12, alkyl, cycloalkyl or S(O).sub.n R.sup.10 ; and R.sup.9 is oxygen or sulphur; where n is 0, 1 or 2; and R.sup.10 is alkyl, haloalkyl or cycloalkyl and R.sup.11 and R.sup.12 are independently selected from hydrogen, alkyl, cycloalkyl, benzyl or substituted benzyl.
