Embodiment 1

[0120] Example 1 10% bisfenpyr + 10% fentrazone suspending agent

[0121] Difenpyr 10%

[0122] Mefentrazone 10%

[0123] Sodium N-Lauroyl Glutamate 5%

[0124] Bentonite 1%

[0125] Propylene Glycol 5%

[0126] Silicone 3%

[0127] Water to make up to 100%

[0128] The active ingredient and various additives are mixed with water, dispersed by high-speed shearing, and sanded by a sand mill to form a highly dispersed and stable suspension system to obtain a suspending agent.

Embodiment 2

[0129] Example 2 20% bisfenpyr + 10% fentrazone wettable powder

[0130] Difenpyr 20%

[0131] Mefentrazone 10%

[0132] Sodium butylnaphthalene sulfonate 5%

[0133] Sodium dipolyoxyethylene lauryl ether phosphate 5%

[0134] Silica 5%

[0135] Kaolin supplemented to 100%

[0136] The active components, various additives and fillers are mixed according to the ratio of the formula, and after being pulverized by an ultrafine grinder, a wettable powder of 20% dipacenil + 10% mefentrazone is obtained.

Embodiment 3

[0137] Example 3 5% bisfenpyr + 25% fentrazone wettable powder

[0138] Difenpyr 5%

[0139] Mefentrazone 25%

[0140] Glycerin fatty acid polyoxyethylene ether 1%

[0141] Sodium lignosulfonate 2%

[0142] Silica make up to 100%

[0143] The active components, various additives and fillers are mixed according to the ratio of the formula, and after being pulverized by an ultra-fine pulverizer, a wettable powder of 5% dipacenil + 25% mefentrazone is obtained.

Abstract

The invention provides weeding composition. The weeding composition comprises active ingredients as follows: pyraclonil and carfentrazone-ethyl in a weight ratio being 50:1-1:10. The invention furtherrelates to an application of the weeding composition in control for growth of undesirable plants such as monocotyledonous and dicotyledonous weeds, in particular to an application of the weeding composition in control for undesirable plants in grain crops. The invention further provides a method for controlling growth of the undesirable plants. The method comprises the step as follows: the effective weeding amount of the weeding composition is contacted with the undesirable plants, or growing places of the undesirable plants or the effective weeding amount of the weeding composition is applied to soil to prevent the undesirable plants from germination or growth.

Description

Technical field [0001] The invention belongs to the field of pesticides. The present invention relates to a herbicidal composition. The invention also relates to a method of controlling undesirable plant growth. Background technique [0002] The prevention and control of agricultural weeds has always been the most concerned and important issue in agricultural production. Protecting crops from weeds and other vegetation that inhibits 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 of herbicides have increased year by year, and the application area has also expanded year by year. However, with the continuous use of many herbicide varieties in large areas, many problems have arisen. For example, the problem of weed resistance has begun to emerge, especially the resistance of older weeds. In addition, a single herbicide has a single mode of action and a...
