specific Embodiment approach

[0059] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited to these specific implementations. Those skilled in the art will realize that the present invention covers all alternatives, modifications and equivalents as may be included within the scope of the claims.

Embodiment 1

[0063] 50% pyrifluzal + 1% oxyfluorfen wettable powder

[0064] The composition of the formula is: 50% of pyrifluzal, 1% of oxyfluorfen, 8% of sodium naphthalenesulfonate formaldehyde condensate, 6% of alkylphenol polyoxyethylene ether phosphate, and the balance of kaolin;

[0065] The preparation method is as follows: weighing the above-mentioned components in the formula amount, mixing, grinding and pulverizing them to obtain wettable powder.

Embodiment 2

[0067] 1% pyrimethiazole + 50% oxyfluorfen wettable powder

[0068] The composition of the formula is: 1% pyrifluzal, 50% oxyfluorfen, 8% fatty alcohol polyoxyethylene ether sodium sulfate, 8% trisiloxane polyoxyethylene ether, and the balance of bentonite;

[0069] The preparation method is as follows: weighing the above-mentioned components in the formula amount, mixing, grinding and pulverizing them to obtain wettable powder.

Abstract

The invention belongs to the agricultural field, and relates to a weeding composition, in particular to a weeding composition containing pyrithiobac-sodium and oxyfluorfen and application thereof. The weeding composition contains pyrithiobac-sodium and oxyfluorfen by the weight ratio of 100:1-1:100. The invention further relates to application of the weeding composition in preventing and killing undesirable plants such as broadleaf weeds, cyperaceae weeds and gramineous weeds.

Description

technical field [0001] The present invention relates to the field of agriculture, in particular to a herbicidal composition, in particular to a herbicidal composition containing pyriflume and oxyfluorfen and its application. Background technique [0002] In crop farming, it is important to control weeds and protect crops that inhibit crop growth and result in lower yields. In order to reduce losses due to weeds in crop cultivation, such as poor growth or reduced crop yield, some herbicidal active ingredients that are effective in controlling the weeds and are safe to crops have been developed. To date, a large number of herbicides have been developed that have been registered and used to control weeds in certain crops. Herbicides for controlling weeds in specific crop cultivation should have sufficiently high herbicidal activity and broad herbicidal spectrum, and should be sufficiently safe for the environment and crops. However, not all herbicides can fully meet the above...
