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

Example Embodiment

[0105] Example 1: Suspension concentrate of 60% sulfone metazoxazole + 6% methyl thifensulfuron

[0106]

[0107] The active component, dispersant, wetting agent and water are ground and / or high-speed shear mixed uniformly according to the proportion of the formula to prepare a suspension of 60% sulfonepyrazole + 6% methyl thifensulfuron.

Example Embodiment

[0108] Example 2 Wettable powder of 2% sulfone metazoxazole + 10% methyl thifensulfuron

[0109]

[0110] By mixing the active ingredients, various additives and fillers according to the proportion of the formula, and then pulverizing the resulting mixture with an ultrafine pulverizer, a wettable powder of 2% sulfone metazazazole + 10% methyl thifensulfuron is prepared.

Example Embodiment

[0111] Example 3 Wettable powder of 2% sulfone metazoxazole + 50% methyl thifensulfuron

[0112]

[0113] By mixing the active components, various additives and fillers according to the proportion of the formula, and then pulverizing the resulting mixture with an ultrafine pulverizer, a wettable powder of 2% sulfonepyrazole + 50% methyl thifensulfuron is prepared.

Abstract

The present invention provides a synergistic herbicidal composition comprising Pyroxasulfone and Thifensulfuron methyl as the active components, 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 theactive components Pyroxasulfone and Thifensulfuron methyl of the synergistic herbicidal composition of present invention to the undesirable plants or their growing locus jointly or separately. The present invention further provides a method of reducing or preventing harm caused by Pyroxasulfone when applied to plants, seeds or other reproductive parts of useful crops.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Australian Patent Application No. AU2016200567, filed 29 January 2016, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to synergistic herbicidal compositions and methods of controlling undesired vegetation. Background technique [0004] The yield of crops can be reduced due to weed damage. To recover yield loss, large herbicides must be applied annually for weed control. In recent years, weeds have become more and more harmful to crops. In addition, the abuse of herbicides has increased the resistance of weeds to pesticides, causing the weed control effect to decrease year by year. [0005] A traditional method of enhancing the herbicidal activity and broadening the herbicidal spectrum of existing herbicides is to mix two or more herbicidal substances with different herbicidal activities. If two...
