Description

BIOLOGICAL EXAMPLES

[0300] Post-Emergence Safener Action

[0301] Seeds of monocotyledonous crop plants were placed in sandy loam in wood-fiber or plastic pots, covered with soil and cultivated in a greenhouse under good growth conditions. Ten to twenty days after sowing, the test plants were treated at the one- to three-leaf stage. The herbicide safener combinations according to the invention formulated as water-soluble powders or suspensions and the correspondingly formulated herbicidally active individual compounds were, at different dosages using a water application rate of 300 l/ha (converted), and with addition of customary wetting agents and adjuvants, sprayed onto the green parts of the plants. After the treatment, the pots were maintained in a greenhouse under good growth conditions for the crop plants.

[0302] 9 to 11 days and 20 to 21 days after application, the damage in percent on the treated crop plants was rated by visual scoring in comparison to the respective untreated controls.

[0303] Combinations in which the herbicidally active individual compound caused at least 30% damage to the crop plant, and where this could be reduced by at least 30 percentage points by addition of 100 g/ha safener, were rated as evidence of significant safener action.

[0304] On wheat, for example, a significant safener action was observed with the following herbicide safener combinations: (A4-2)+(S1-1), (A4-2)+(S1-7), (A4-2)+(S1-11), (A4-2)+(52-1), (A4-2)+(53-4), (A4-2)+(S3-10), (A4-2)+(S4-6), (A4-2)+(S11-2), (A4-13)+(S1-1), (A4-13)+(S1-7), (A4-13)+(S1-11), (A4-13)+(S2-1), (A4-13)+(S3-4), (A4-13)+(S3-10), (A4-13)+(S4-1), (A4-13)+(54-6), (A4-13)+(S11-2).

[0305] On barley, for example, a significant safener action was observed with the following herbicide safener combinations: (A4-2)+(S2-1), (A4-2)+(S3-4), (A4-2)+(S3-10), (A4-2)+(S11-2), (A4-13)+(S11-2).

[0306] On rice, for example, a significant safener action was observed with the following herbicide safener combinations: (A4-2)+(S1-11), (A4-2)+(S3-10), (A4-2)+(S4-1), (A4-2)+(S4-6), (A4-13)+(S1-7), (A4-13)+(S1-11), (A4-13)+(S3-10), (A4-13)+(S4-6).

[0307] On corn, for example, a significant safener action was observed with the following herbicide safener combinations: (A4-2)+(S1-11), (A4-2)+(S2-1), (A4-2)+(S3-10), (A4-2)+(S4-1), (A4-2)+(S4-6), (A4-2)+(S11-2), (A4-13)+(S1-11), (A4-13)+(S2-1), (A4-13)+(S4-1), (A4-13)+(S4-6), (A4-29)+(S1-11), (A4-29)+(S2-1), (A4-29)+(S4-1), (A4-29)+(S4-6), (A4-29)+(S11-2).

[0308] Pre-Emergence Safener Action

[0309] Corn seeds were placed in sandy loam in wood-fiber pots and covered with soil. The herbicide safener combinations according to the invention formulated as water-soluble powders or suspensions and the correspondingly formulated herbicidally active individual compounds were, at different dosages using a water application rate of 300 l/ha (converted), and with addition of customary wetting agents and adjuvants, sprayed onto the surface of the covering soil. After the treatment, the pots were kept in a greenhouse under good growth conditions for the crop plants.

[0310] 9 to 11 days and 20 to 21 days after application, the damage in percent on the treated crop plants was rated by visual scoring in comparison to the respective untreated controls. Combinations in which the herbicidally active individual compound caused at least 30% damage to the crop plant, and where this could be reduced by at least 30 percentage points by addition of 100 g/ha safener, were rated as evidence of significant safener action.

[0311] On corn, for example, a significant safener action was observed with the following herbicide safener combinations:
