- Bispyribac sodium
- pyribenzoxime penoxsulam and orthosulfamuron on the one hand (group A) and anilofos (group B) on the other hand.
- 2,6-bis (4,6-dimethoxypyrimidin-2-yloxy) benzoic acid is known as a herbicide and is described inter alia in EP 321846 A2 (see also "The Pesticide Manual", 11th edition (2003) , published by the British Crop Protection Council), with the sodium salt of the compound being particularly preferred (bispyribac-sodium) Bispyribac is a so-called ALS inhibitor.
- O- [2,6-bis (4,6-dimethoxypyrimidin-2-yloxy) benzoyl] benzophenone oxime is likewise a known herbicide and is described, for example, in EP 0 658 549 A1 (see also "The Pesticide Manual”). , 13th Edition (2003), published by the British Crop Protection Council.) Pyribenzoxime is also an ALS inhibitor.
- Trifluorotoluene-2-sulfonamide is also a known herbicide and is, for example in US 5,858,924 (see also "The Pesticide Manual", 13th Edition (2003), published by the British Crop Protection Council.) Penoxsulam is also an ALS inhibitor.
- the effectiveness of these herbicides against harmful plants in the crops is at a high level, but generally depends on the application rate, the particular preparation form, each to be controlled harmful plants or the Schadessespektrum, the climate and soil conditions, etc. from. Another criterion is the duration of the action or the degradation rate of the herbicide. If necessary, also changes in the Sensitivity of harmful plants, which may occur with prolonged use of herbicides or geographically limited. Losses in individual harmful plants can be compensated only conditionally by higher application rates of herbicides, for example, because often the selectivity of the herbicides is deteriorated or an improvement in the effect does not occur even at higher application rates. In part, the selectivity in cultures can be improved by adding safeners. Generally, however, there is always a need for methods to achieve the herbicidal effect with lower application rate in active ingredients. A lower application rate not only reduces the amount of an active ingredient required for the application, but usually also reduces the amount of necessary
- Formulation auxiliaries Both reduce the economic effort and improve the environmental compatibility of the herbicide treatment.
- One way to improve the application profile of a herbicide may be to combine the active ingredient with one or more other active ingredients.

- a water dispersible granule is also obtained by adding 25 parts by weight of a drug / active substance mixture, 5 parts by weight of sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, 2 parts by weight of oleoylmethyltaurine sodium , 1 part by weight of polyvinyl alcohol, 17 parts by weight of calcium carbonate and 50 parts by weight of water homogenized and pre-crushed on a colloid mill, then grinded on a bead mill and the resulting suspension in a spray tower by means of a Einstoffdüse atomized and dried.
- X the kill rate, expressed as% of untreated control, in
- E the expected kill rate, expressed as% of untreated
- Control when using the active ingredient A and B in an application rate of m and n ppm means
- the combination is over-additive in its kill, i. there is a synergistic effect.
- the actually observed kill rate must be greater than the expected kill rate (E) value calculated from the above formula.
- the preparation of active compound (see Table A) was mixed with water. It is set a concentration corresponding to a water application rate of 200 l / ha.
- Rice seeds are sown on experimental plots (2 mx 5 m) on rice fields. 18 days after sowing (in the 6-leaf stage of the rice), the spray preparation is applied to the test areas (application with a backpack syringe). Multiple - depending on the soil moisture - after sowing and after treatment, the soil is overstored to a depth of 3 - 5 cm.
