Abstract

The invention relates to a weeding composition and a method for preventing and removing weeds by using the weeding composition. The weeding composition provided by the invention comprises active components (I) and (II), wherein the active component (I) is a compound described in the formula (I) (shown in the description), the active component (II) is a compound described in the formula (II) (shown in the description), and the weight ratio of the active component (I) to the active component (II) is (100:1)-(1:100).

Description

Technical field [0001] The present invention relates to a herbicidal composition and a method for controlling undesirable plants. Background technique [0002] When herbicides are used alone, their effects are usually only temporary, i.e. weed resistance is observed after a certain period of time. In crop protection, it is in principle desirable to increase the activity of active compounds and the reliability of their effects. It is particularly desirable that the active compounds effectively control undesirable plants but are at the same time compatible with the useful plants of concern. It is therefore desirable that the active compounds be used at the lowest possible application rates, achieving the highest possible compatibility with the useful plants. [0003] Propyrisulfuron (Propyrisulfuron), molecular formula is C 16 H 18 O 5 N 7 SCl, its molecular structure is as follows: [0004] (Formula I) [0005] Promethasulfuron is a pyrimidinyl sulfonylurea herbicid...
