The compounds of formula VII are known or can be prepared by analogy with known methods; see Houben-Weyl , "Methoden der organischen Chemie" [Methods of Organic Chemistry], Vol. VIII, p. 120 (1952) , Houben-Weyl, Vol. IX, pp. 875, 869 (1955); EP-B 0 070 389; US-A 4 881 967; EP-A 0 322 401; US-A 3 495 967; EP-A 0 300 307; EP-A 0 349 832.
It may be that some of the compounds of formula I are difficult to synthesize or of little stability. Such compounds are normally not preferred. Preferred are compounds which are with respect to their desired application easy to prepare and stable enough for use. For biodegradation instability can be an advantage for the purpose of use.
Finally, it was found that the novel anellated triazole compounds of general formula I and II exhibit outstanding herbicidal qualities.

Formulations
Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to about 99% by weight of active ingredient ( s ) and at least one of (a) up to about 20% surfactant( s ) and (b) up to about 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:
Weight Percent Active Ingredient Diluent(s) Surfactant ( s )
Wettable Powders 20-90 0-74 1-10
Oil Suspensions, 3-50 40-95 0-15
Emulsions, Solutions, (including Emulsifi¬ able Concentrates)
Aqueous Suspension 10-50 40-84 1-20
Dusts 1-25 70-99 0-5
Granules and Pellets 0.1-95 5-99.9 0-15
High Strength 90-99 0-10 0-2
Compositions
Active ingredient plus at least one of a surfactant or a diluent equals 100 weight percent.
Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.
Typical solid diluents are described in Watkins, et al. , "Handbook of Insecticide Dust Diluents and Carriers" , 2nd Ed. , Dorland Books, Caldwell, New Jersey, but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide", 2nd Ed. , Interscience , New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solutions concentrates are preferably stable against phase separation at 0°C. "McCutcheon ' s Detergents and Emulsifiers Annual", MC Publishing Corp. , Ridgewood , New Jersey, as.well as Sisely and Wood, "Encyclopedia of Surface Active Agents" , Chemical Publishing Co. , Inc. , New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.
The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, US-A 3,060,084) .
Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J.E. Browning, "Agglomeration" , Chemical Engineering. December 4,
1967, pp. 147ff and "Perry ' s Chemical Engineer ' s Handbook" , 5th Ed. , McGraw-Hill, New York, 1973, pp. 8-57ff .

Utility
The compounds of the present invention are active herbicides. They have utility for broadspectrum preemergence and/or postemergence weed control in areas where complete control of all vegetation is desired, such as around industrial complexes, storage areas, parking lots, drive-in theaters, around billboards, fence rows, highway and railroad structures. Some of the compounds have utility for selective weed control in crops such as rice, wheat, barley, corn, soybeans, sugarbeets, cotton, peanut, all plantation crops including coffee, cocoa, sugarcane, oil palm, rubber, citrus, grapes, fruit trees, nut trees, banana, plantain, pineapple and conifers such as loblolly pine.
The compounds can be applied as a preemergence and/or postemergence treatment using techniques of banding, directed sprays or broadcast applications. The rates of application for the compounds of the invention are determined by a number of factors, including their use as selective or general herbicides, the crop species involved, the types of weeds to be controlled, weather, climate, formulations selected, mode of application, amount of foliage present, etc. By selecting the appropriate rate which would be apparent to one skilled in the art, the compounds of this invention can be used in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, oil well sites, drive-in theaters, around billboards, highway and railroad structures and in
fence rows. Alternatively, by selecting the proper rates and adjuvants, the compounds of this invention can be used for selective weeds control in peanuts and plantation corps such as citrus, sugarecane, coffee, oil palm, rubber, cocoa, grapes, fruit trees, nut trees, pineapple and banana. In general, the subject compounds are applied at levels of around 0.001 to 20 kg/ha, with a preferred rate range of 0.01 to 2 kg/ha rate. One skilled in the art can select the proper rates for a given situation.
The compounds of this invention may be used in combination with other herbicides listed below. They are particularly useful in combination with triazine, triazole, uracil, urea, amide, carbamate, bipyridylium, phenoxy, sulfonylurea and imidazole types for total vegetation control in plantation and other crops. The compounds may also be used in combination with mefluidide , glyphosate or gluphosinate.

Test procedure
Seeds of crabgrass (Digitaria spp. ), barnyardgrass (Echinochloa crus-galli) , giant foxtail (Setaria faberii) , wild oats (Avena fatua) , cheatgrass (Bromus secalinus) , velvetleaf (Abutilon theophrasti ) , morningglory (Ipomoea spp. ) , cocklebur (Xanthium pensylvanicum) and sorghum. Nutsedge tubers were planted and treated preemergence with the test chemicals dissolved in a non-phytotoxic solvent. At the same time, these weed species were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were visually rated for response to treatment and compared to controls. The ratings, summarized in Table A, are based on a numerical scale extending from 0 = no injury, to 10 = complete kill.
The accompanying descriptive symbols have the following meanings:
C = chlorosis/necrosis ;
B = burn
H = formative effect;
G = growth retardation;
E = emergence inhibition.
