Embodiment 1

[0113] Example 1 17.5% flufenacet + 10% metrizone + 13.5% clomazone Suspending agent

[0114]

[0115] Mix the active components and various additives with water, disperse by high-speed shearing, and grind with a sand mill to form a highly dispersed and stable suspension system to prepare 17.5% flufenacet + 10% metrizone + 13.5% clomazone suspension concentrate.

Embodiment 2

[0116] Example 2 15% flufenacet + 15% metrizone + 10% clomazone wettable powder

[0117]

[0118] Mix the active ingredients, various additives and fillers according to the ratio of the formula, and pulverize them with an ultra-fine pulverizer to obtain 15% flufenacet + 15% mecitrazone + 10% clomazone Wettability powder.

Embodiment 3

[0119] Example 3 10% flufenacet + 12% metrizone + 8% clomazone water dispersible granules

[0120]

[0121] Mix active components, dispersants, wetting agents, disintegrants and fillers evenly according to the ratio of the formula, and then crush them into wettable powders through airflow, then add a certain amount of water to mix and extrude the materials, and obtain them after drying and sieving 10% flufenacet + 12% metrizone + 8% clomazone water dispersible granules.

Abstract

The invention provides a weeding composition. The weeding composition comprises the active ingredients: flufenacet and metribuzin or flufenacet, metribuzin and clomazone. The invention also relates toapplication of the weeding composition in control of the growth of undesired plants of monocotyledonous weeds and dicotyledonous weeds, and also provides a method for controlling the growth of the undesired plants. The method includes the steps: performing contact of the undesired plants or growth sites of the plants with the weeding composition of a weeding effective amount, or applying the weeding composition of a weeding effective amount to soil so as to prevent the undesired plants from germinating or growing.

Description

technical field [0001] The invention belongs to the field of pesticides; the invention relates to a herbicidal composition; the invention also relates to a method for controlling unwanted plant growth. Background technique [0002] The control of agricultural weeds has always been the most concerned and important issue in agricultural production. Protecting crops from weeds and other vegetation that inhibit crop growth is an ongoing problem in agriculture. [0003] The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, the sales volume of herbicides has increased year by year, and the application area has also expanded year by year. However, with the continued use of many herbicide varieties on a large scale, many problems have arisen, such as the problem of weed resistance, especially the problem of resistance to older weeds is particularly prominent; Issues such as short validity periods are also prominent. Therefore, it ...
