Benefits of technology

This patent aims to provide herbicidal compositions that have better weed control, are compatible with crop plants, and can be used at lower application rates compared to individual compounds. Additionally, the compositions should provide equal or better weed control while causing less damage to the crop.

Problems solved by technology

Frequently, this cannot be achieved using a single herbicidally active compound.
For example, herbicide resistance within weeds, in particular grass weeds such as, for example, Alopecurus myosuroides (ALOMY), Apera spica-venti (APESV) or Lolium species (LOLSS) has become a major concern for farmers, resulting in dramatic weed control problems, for example in cereal crops.

examples

[0293]The effect of the herbicidal compositions according to the invention of herbicides A and B on the growth of undesirable plants compared to the herbicidally active compounds alone was demonstrated by the following greenhouse experiments:

[0294]The test plants have been seeded, separately for each species, in plastic containers in sandy loamy soil containing 5% of organic matter.

[0295]For the pre-emergence treatment, the active compounds, suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transparent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants unless this was adversely affected by the active compounds.

[0296]For the post emergence treatment, the plants were first grown to the 2 leaf station (GS 12). Here, the herbicidal compositions were suspended or emulsified in wate...

Abstract

The present invention relates to a herbicidal composition comprising saflufenacil. The invention also relates to methods and uses for controlling undesirable vegetation, in particular in crops.

Description

[0001]The present invention relates to a herbicidal composition comprising saflufenacil. The invention also relates to methods and uses for controlling undesirable vegetation, in particular in crops.BACKGROUND OF THE INVENTION[0002]In crop protection, it is desirable, in principle, to increase the specific activity of an active compound and the reliability of the effect. It is particularly desirable for the crop protection product to control the harmful plants effectively, but at the same time to be compatible with the useful plants in question. Also desirable is a broad spectrum of activity allowing the simultaneous control of harmful plants. Frequently, this cannot be achieved using a single herbicidally active compound.[0003]Further, cases of herbicide-resistant weeds are becoming increasingly common. These biotypes survive herbicide application at doses that usually give effective control of the species. Resistant weed biotypes are a consequence of basic evolutionary processes. ...
