Embodiment 1

[0034] Bicyclic sulcotrione 0.5%, Pendimethalin 0.6%, Difenpyr 0.5%, Sodium a-alkenyl sulfonate (AOS) 1%, Sodium lignosulfonate (REAX82P) 4%, Glucose 6%, White Carbon black 5%, kaolin the balance. Mix all the above-mentioned ingredients evenly according to the stated ratio, and through airflow crushing, the average particle size of the material is less than 5 microns, and knead evenly with water, move to granulation equipment to granulate, and dry at 45°C to obtain 1.6% bicyclic sulfone Oxazone · Pendimethalin · Difenpyr granules (5:6:5).

Embodiment 2

[0036] Bicyclic Sulfotrione 0.5%, Pendimethalin 0.2%, Dimefenac 0.6%, Sodium Lauryl Sulfate 1%, Naphthalene Sulfonate Dispersant (MORWET D425) 5%, Polyethylene Glycol 4000 5% , white carbon black 10%, attapulgite balance. Mix all the above-mentioned ingredients uniformly according to the stated proportions, and through jet crushing, make the average particle size of the material less than 5 microns, add water and knead evenly, move to granulation equipment to granulate, and dry at 45°C to obtain 1.3% bicyclic sulfonate Oxazone · Pendimethalin · Difenpyr Granules (15:6:18).

Embodiment 3

[0038] Bicyclic sulcotrione 10%, pendimethalin 12%, bisacenil 18%, calcium dodecylbenzenesulfonate 8%, sodium lignosulfonate 7%, fatty alcohol polyoxyethylene ether 3%, white Carbon black 8%, kaolin the balance. Mix all the ingredients evenly according to the above ratio, and make the average particle size of the material less than 5um through jet milling. The 40% bicyclic sulcotrione·dimethalin·difenpyr wettable powder (10:12:18) can be obtained.

Abstract

The invention discloses an herbicidal composition containing benzobicylon, pendimethalin and pyraclonil. The herbicidal composition comprises the following effective components: benzobicylon, pendimethalin and pyraclonil, wherein a weight ratio of benzobicylon to pendimethalin to pyraclonil in the herbicidal composition is (5-15) to (6-18) to (5-15); and a total weight percentage of benzobicylon,pendimethalin and pyraclonil in the composition is 1%-80%. The herbicidal composition provided by the invention can significantly expand a weed-controlling spectrum, improves an overall control effecton weeds in paddy fields, also has high safety to rice, and is a very good novel drug composition for controlling annual weeds in the paddy fields.

Description

technical field [0001] The invention belongs to the technical field of agrochemicals, and in particular relates to a herbicidal composition containing bicyclic sulcotrione, pendimethalin and dipacenil. Background technique [0002] Bicyclic sulcotrione (benzobicylon) belongs to bicyclooctane herbicides, and its mechanism of action is a p-hydroxyphenylpyruvate dioxygenase inhibitor. The compound is safe to rice, and can effectively control barnyard grass, bermudagrass, moshangcai, sagittarius, yujiuhua, flat stalk and other malignant weeds in rice fields. [0003] The chemical name of pendimethalin is N-(1-ethylpropyl)-2,6-dinitro-3,4-dimethylaniline, which belongs to meristem cell division inhibitor. During the germination process of weed seeds, the young shoots, young stems, and young roots absorb the drug and work, and finally the young shoots and secondary roots are inhibited, eventually leading to death. [0004] Pyraclonil belongs to a new type of bispyrazole herbicid...
