These agents can be applied in a conventional manner, for example in combination with water as the carrier material in the form of a spray mixture in a volume amount of about 100 to about 1000 liters / hectare. These agents can also be applied by means of low-volume or ultra-low-volume methods or in the form of so-called microgranules.

The preparation of these compositions according to the invention can be carried out in a manner known per se, for example by grinding or mixing. Alternatively, it is also possible to mix the individual components just before use, for example by the so-called generally used mixing method in the container.

DETAILED DESCRIPTION OF THE INVENTION

The herbicidal composition of the present invention and its use in the propagation of various weed species will be illustrated in the following examples, which are illustrative only and are not intended to limit the scope of the invention.

The calculation of the synergistic effect was performed by S. R. Colby's method of Calculating Synergistic and Antagonistic Response to Herbicide Combinations, Veeds, 15/1, 1967, p. 20-22. For these purposes, the following relationship was used:

XY

E = X + Y ------ 100 in which:

X = herbicidal activity (%) of substance A used at p g / ha,

Y = herbicidal activity (%) of substance B used in g g / ha, and

E is the expected sum of the efficacy of the herbicidal composition (%) of A + B used at p + g g / ha.

If the observed value is greater than the stated E value calculated by Colby, then this combination of substances exhibits a synergistic effect.

Experimental part.

The individual plant species listed in the following tables, which were grown in a greenhouse, were pre-emergence treated with the active ingredients in the indicated amounts. The ingredients were diluted with 500 liters of water and then sprayed onto the soil. The herbicidal effect was evaluated two weeks after treatment. In the examples, component I is 6- (6,6-dimethyl-3,5,6,7-tetrahydropyrrolo [2,1-c] [1,2,4] thiadiazol-3-ylidenimino) -7-fluoro-4- ( 2-propynyl) -2H-1,4-benzoxazin-3 (4H) -one.
