Patent Trade Mark Attorneys Level 10, 10 Barrack Street SYDNEY NSW 2000 Complete specification for the invention entitled "Halogenated sulphonylaminocarbonyltriazolinones".

The following statement is a best method of performing it full description of this invention, including the known to me:- 1 5020 The invention relates to new halogenated sulphonylaminocarbonyltriazolinones, to several processes for their preparatio.i, and to their use as herbicides.

It is known that certain substituted aminocarbonylimidazolinones, such as, for example, 1-isobutylaminocarbonyl-2-imidazolidinone (isocarbamid), have herbicidal properties (cf. R. Wegler, Chemie der Pflanzenschutz- und Schadlingsbekmpfungsmittel [Chemistry of Plant Protection Agents and Pesticides], Vol. 5, p. 219, Springer- Verlag, Berlin-Heidelberg-New York, 1977). However, the action of this compound is not satisfactory in all respects.

R

R

Surprisingly, the new compounds of the formula have a considerably better herbicidal action than the known herbicide l-isobutylaminocarbonyl-2-imidazolidinone (isocarbamid), which has a similar structure.

The organic phase is separated off, washed with water, dried with sodium sulphate and filtered. The filtrate is concentrated, the residue is stirred with diethyl ether, and the product which is obtained in crystalline form in this process is isolated by filtration with suction.

8.7 g (79 of theory) of 5-bromo-4-dimethylamino-2-phenoxycarbonyl-2,4-dihydro-3H-l,2,4-triazol-3one of melting point 136 0 C are obtained.

Use Examples: In the following Use Examples, the known herbicide isocarbamid of formula below is used as comparison substance: Le A 27 155 51 Y" F7 HNr(NCO-NH-CH 2 CH (CH 3 )~2 0 (disclosed in BE 737,449; DE 1,795,117).

Le A,27 155 52 F I Example A Pre-emergence test Solvent: 5 parts by weight of acetone Emulsifier: 1 part by weight of alkylaryl polyglycol ether To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.

Seeds of the test plants are sown in normal soil and, after 24 hours, watered with the preparation of the active compound. It is expedient to keep constant the amount of water per unit area. The concentration of the active compound in the preparation is of no importance, only the amount of active compound applied per unit area being decisive. After three weeks, the degree of damage to the plants is rated in damage in comparison to the development of the untreated control. The figures denote: 0 no action (like untreated control) 100 total destruction In this test, for example the compounds of Preparation Example 3, 6 and 7 show a clearly suerior activity cormpared with the prior art.

Test plants which have a height of 5 15 cm are sprayed with the preparation of the active compound in such a way as to apply the particular amounts of active compound desired per unit area. The concentration of the spray liquor is so chosen that the particular amounts of active compound desired are applied in 2,000 1 of water/ha. After three weeks, the degree of damage to the plants is rated in damage in comparison to the development of the untreated control. The figures denote: 0% no action (like untreated control) 100% total destruction In this test, for example the compounds of Preparation Example 3, 6 and 7 show a clearly superior activity compared with the prior ait.
