Embodiment 1

[0055] Embodiment 1: emulsifiable concentrate

[0056] 25% isoproturon, 15% salmazone, 0.5% florasulam, 15% fatty alcohol polyoxyethylene ether, and 44.5% heavy aromatic solvent oil are added to 100%, and after mixing and stirring, an emulsifiable concentrate preparation is obtained. According to actual needs, an appropriate amount of xylene can be added to prepare an emulsifiable concentrate preparation with an active ingredient content of 40.5%.

Embodiment 2

[0057] Embodiment 2: water dispersible granules

[0058] 30% isoproturon, 25% salmazone, 1% diflusulam and 3% naphthalenesulfonic acid condensate sodium salt, 2% acyl glutamate, 10% ammonium chloride, 2% white carbon black , 27% kaolin, fully mixed, and then crushed by airflow, and granulated to obtain water-dispersible granules. The water-dispersible granules contain 56% of the active compound, and the particle size of the product is 80-120 mesh.

Embodiment 3

[0059] Embodiment 3: dry suspension

[0060] 40% isoproturon, 20% salmazone, 0.8% florasulam and 2% lignosulfonate, 2% naphthalenesulfonate, 10% ammonium sulfate, 0.3% xanthan gum, 10% white Carbon black and 14.9% kaolin are fully mixed, and then pulverized by ultra-fine airflow to prepare a dry suspension, which contains 60.8% active compound.

Abstract

The invention discloses a herbicidal composition. The herbicidal composition contains active ingredients isoproturon, tralkoxydim and florasulam in a mass ratio of 0.1-90:0.1-80:0.1-50, preferably 5-80:1-60:0.2-20, most preferably 5-60:5-50:0.2-10. A herbicidal composition preparation includes the herbicidal composition and a preparation accessory, by mass percentage, the herbicidal composition accounts for 1-90% of the total amount, preferably 5-75%. The herbicidal composition provided by the invention has the advantages of: 1. high safety to wheat; 2. weeding spectrum, comprehensive killing of various weeds including Gramineae and broadleaf weeds; 3. good weeding effect, and high control effect on wheat and barley field weed; 4. simple and convenient use, soil sealing treatment after wheat sowing or postemergence stem and leaf treatment of weeds; 5. environmental friendliness, difficult drifting, and environmental safety; and 6. quick effect and durable effect, reduction of medication frequency, lowering of work amount and production cost, decrease of phytotoxicity risk, and delaying of weed resistance to herbicides.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicidal composition containing isoproturon, sammazone and florasulam, a preparation and application thereof. Background technique [0002] Wheat is one of the main food crops in my country, and weeding in wheat fields is a major problem in production. Chemical weed control is the main means of controlling weeds. Herbicide varieties containing a single active ingredient often have defects in varying degrees in the control of weeds in agricultural fields. In recent years, due to the large-scale single-dose and continuous use of some herbicide single-agent varieties, many weeds have developed resistance. Therefore, there is an urgent need for new herbicides with high efficiency, low toxicity, economy, safety and broad spectrum. [0003] For the prevention and control of resistant weeds in agriculture, one way is to introduce new ingredients that have no cross-resistance with existing varieties,...
