Embodiment 1

[0009] Example 1, Herbicidal Composition 1

[0010] The active ingredient accounts for 30% of the triflumezin and terbutin herbicidal composition, in every 100 grams, 0.49 grams of triflumezin and 29.51 grams of terbutin (the weight ratio of triflumezin and terbutin is 1: 60), 3 grams of sodium lauryl sulfonate, 3 grams of sodium hydroxymethylcellulose, and 64 grams of water were added, subjected to high-speed shearing, wet sanding, and finally homogeneous filtration to prepare a suspension herbicidal composition 1.

Embodiment 2

[0011] Example 2, herbicidal composition 2

[0012] The active ingredient accounts for 30% of the triflumezin and terbutin herbicidal composition, in every 100 grams, 0.67 grams of triflumezin and 29.33 grams of terbutin (the weight ratio of triflumezin and terbutin is 1: 45), 3 grams of sodium lauryl sulfonate, 3 grams of sodium hydroxymethylcellulose, and 64 grams of water were added, subjected to high-speed shearing, wet sanding, and finally homogeneous filtration to prepare the suspension herbicidal composition 2.

Embodiment 3

[0013] Example 3, herbicidal composition 3

[0014] The active ingredient accounts for 30% of the triflumezin and terbutin herbicidal composition, in every 100 grams, 0.97 grams of triflumezin and 29.03 grams of terbutin (the weight ratio of triflumezin and terbutin is 1: 30), 3 grams of sodium lauryl sulfonate, 3 grams of sodium hydroxymethyl cellulose, 64 grams of water, high-speed shearing, wet sanding, and finally homogeneous filtration to prepare the herbicidal composition 3 for suspension.

Abstract

The present invention relates to the technical field of pesticide production, and discloses a weeding composition as well as a preparation method and application thereof. The composition contains two active components such as trifluoro-metribuzin and terbutryn, then an emulsifier and a thickener are added and mixed with water; and finally a suspending agent, namely the composition, is prepared after high-speed shearing, wet sand milling and finally homogeneous filtration. The weight ratio of trifluoro-metribuzin to terbutryn in the composition is 1: (30-60), and the weight percentage of the two active components such as trifluoro-metribuzin and terbutryn in the composition is 30-70%. The weeding composition disclosed by the present invention is mainly used for soil treatment, and can effectively prevent and control weeds in wheat and corn fields. The defect of single active component in prevention and control is improved, and the weeding composition has a remarkably synergistic effect in preventing and controlling both annual gramineous weeds and broadleaf weeds and cyperaceous weeds. The composition not only can effectively prevent and control the weeds but also is good in safety, and has no effect on afterreap crop, so that the composition is an ideal weeding composition.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a herbicide composition, more specifically, it relates to a herbicide compounded with triflumezin and terbuthine for wheat fields and corn fields. Background technique [0002] With the modernization of agriculture, farmers use a series of chemical products such as chemical pesticides, biological pesticides and pesticide mixtures in agricultural production. The most popular pesticide products are herbicides. The sales of herbicides have always ranked first among pesticides. at the forefront. However, there are many varieties of herbicides on the market, and at the same time, the requirements for application technology are high. A little carelessness in the application will cause problems such as phytotoxicity and poor weeding effect. With the application of herbicides more and more widely, some weeds Grasses have become resistant to a single herbicide, resulting in more and...
