Embodiment Construction

[0795] Adopt following embodiment to illustrate the present invention:

[0796] A: Formulation Example

[0797] a) The preparation of powder is that the active substance mixture of 10 weight parts sulfonylurea (A) or safener (B) or sulfonylurea (A) and safener (B) and the talc of 90 weight parts (as inert substance ) were mixed and the mixture was pulverized in a hammer mill.

[0798] b) The preparation of the wettable powder which is easy to disperse in water is the active substance mixture of 25 parts by weight of sulfonylurea (A) or safener (B) or sulfonylurea (A) and safener (B), 64 parts by weight 1 part of kaolin-containing quartz is used as an inert substance, 10 parts by weight of potassium lignosulfonate and 1 part by weight of sodium oleoyl methyl taurate are mixed as a wetting agent and a dispersant, and are mixed in a plug-type disc mill Grind in machine.

[0799] c) The preparation of the concentrate that is easy to disperse or suspend in water is the active su...

Abstract

Herbicidal composition comprises a sulfonylurea herbicide (I) and a safener (II), where (I) is metsulfuron, thifensulfuron, tribenuron, chlorsulfuron or a salt or ester thereof and (II) is mefenpyr, isoxadifen, cloquintocet, fenchlorazol or its salt or ester. - An INDEPENDENT CLAIM is also included for controlling harmful plants in crops by applying the components of a composition as above together or separately to the harmful plants, the crop plants, plant seeds or growing surface. - ACTIVITY - Herbicide. - MECHANISM OF ACTION - None given.

Description

technical field [0001] The present invention relates to the technical field of plant protection compositions, in particular herbicidally active compositions comprising a sulfonylurea / safener combination (active substance-antidote-combination) and which are highly suitable for controlling competing harmful plants in useful crops. Background technique [0002] Combinations of herbicides and safeners which inhibit acetolactate synthase (ALS) are known. Thus, EP 0 492 367 A2 describes the combination of different ALS inhibitors with different safeners. However, the combinations specifically disclosed in this document are not always sufficient with regard to selectivity and activity spectrum. Contents of the invention [0003] It was therefore the object of the present invention to provide herbicidally active compositions which have an increased selectivity for important crops and at the same time a high activity against harmful plants. Surprisingly, this task was solved by t...
