Examples

1. Methods used in the prior art

For the untreated control group, wheat seeds (winter wheat, TRZAW) were placed in sandy loam in pots 7cm in diameter, covered with soil, and grown in the greenhouse under good growth conditions.

Post-emergence applications are performed when plants have reached the growth stage of BBCH11(BBCH is the international coding system for the crop and weed growth stages).

The herbicide (compound I) was formulated as an Emulsion Concentrate (EC).

The safener (mefenpyr-diethyl) is formulated as a Wettable Powder (WP).

The compounds were sprayed as an aqueous suspension onto the green parts of the plants at an equivalent water application rate of 300L/ha.

The combination of herbicide and safener is applied as a tank mix (tank mix).

After application, the test plants were kept in a greenhouse with good growth conditions. At 14 days post-application, the% crop damage observed on the treated plants was assessed visually compared to untreated controls.

The values in the table below are the average of at least 3 replicates.

2. Method A

For the untreated control group, wheat seeds (winter wheat, TRZAW) were placed in sandy loam in pots 7cm in diameter, covered with soil, and grown in the greenhouse under good growth conditions.

For seed treatment with safener, enough seed was weighed into a screw-top glass bottle about twice the seed volume.

The safener (mefenpyr-diethyl, formulated as a Suspension Concentrate (SC)) was weighed out so that the desired ratio (g a.i./kg seeds) could be obtained, dissolved in water (1mL of water per 10g of seeds) and added to the seeds to produce a slurry.

The bottles were capped and then placed in an overhead shaker (set at medium speed for up to 1 hour) to allow the seeds to be evenly coated with the slurry. The bottle is opened and the seeds are sown as described above.

For the seed treatment method, a blind formulation (SC formulation without safener mefenpyr) was used as seed treatment as described above.

The post-emergence application of the herbicide was carried out when the plants had reached the growth stage of BBCH 11.

The herbicide (compound I) was formulated as an Emulsion Concentrate (EC) and sprayed as an aqueous suspension onto the green parts of plants at an equivalent water application rate of 300L/ha.

After application, the test plants were kept in a greenhouse with good growth conditions. At 14 days post-application, the% crop damage observed on the treated plants was assessed visually compared to untreated controls.
