Problems solved by technology

The application of a single herbicide cannot be completely effective in controlling weeds in crop fields. On the other hand, excessive or uneven application of herbicides may cause unacceptable toxicity to current crops or subsequent crops.

Metrafenazole is a highly effective pre-emergence herbicide, but its post-emergence activity is poor

In addition, the compatibility of pyraconazole with certain dicotyled...

Method used

[0061] The synergistic herbicidal compositions of the present invention may also comprise one or more safeners. Safeners are organic compounds which, when applied in combination with specifically acting herbicides, lead to better crop compatibility under certain circumstances. Safeners act as antidotes or antagonists in crops, thereby reducing or even preventing damage to the crops.

[0217] It can be seen that the crop phytotoxicity of the synergistic herbicidal composition of the present inventi...

Abstract

The present invention provides a synergistic herbicidal composition comprising Pyroxasulfone, Topramezone and Atrazine as the active components, wherein the weight ratio of Pyroxasulfone, Topramezoneand Atrazine ranges from 1 to 10: 1 to 10: 1 to 100, as well as the use of the synergistic herbicidal composition of present invention for controlling the growth of undesirable plants. The present invention also provides a method of controlling the growth of undesirable plants, which comprises applying the active components Pyroxasulfone, Topramezone and Atrazine of the synergistic herbicidal composition of present invention to the undesirable plants or their growing locus or separately. The present invention further provides a method of reducing or preventing harm caused by Pyroxasulfone whenapplied to plants, seeds or other reproductive parts of useful crops.
