Embodiment 1

[0024] Test name: Indoor activity determination test of tembotrione, sulfentrazone and isoproturon on weeds.

[0025] Purpose of the test: Through the greenhouse pot activity assay test, the synergistic effect of the mixed use of tembotrione, sulfentrazone and isoproturon on weeds is more clear, and the weed control between the compositions and between the composition and a single agent is further compared Activity, in order to better illustrate the herbicidal composition of the present invention.

[0026] Test targets: Rice Lishihe and Green-stalked Barnyard Grass were selected as test targets. Rice Lishihe was collected and planted from the Jinhua field in Zhejiang, and Green-stalked Barnyardgrass seeds were collected from Nanling County, Anhui Province.

[0027] Test agents: 97.4% tembotrione TC, 94% sulfentrazone TC and 98% isoproturon TC.

[0028] Test medicament and preparation: Weigh a certain amount of the original drug, choose a suitable organic solvent to dissolve i...

preparation Embodiment

[0040] In each of the following examples, 97.4% tembotrione TC, 95% sulfentrazone TC and 98% isoproturon TC are used as the active ingredients, and the percentages of each component are weight percentages.

[0041] Example 1: 9% tembotrione. sulfentrazone. isoproturon (0.8:1.8:6.4) granules

[0042]Termetrione 0.8%, Sulfentrazone 1.8%, Isoproturon 6.4%, Sodium Lauryl Sulfate 2%, Alkylphenol Polyoxyethylene Formaldehyde Condensate Sulfate 7%, Sodium Lignosulfonate 5%, Ammonium sulfate 10%, corn starch 10%, kaolin clay balance. Mix all the 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 for granulation, and dry to obtain 9% tembotrione. Sulcolam. Isoproturon (0.8:1.8:6.4) granules.

Embodiment 2

[0043] Example 2: 8.7% tembotrione. sulfentrazone. isoproturon (0.6:1.8:6.3) granules

[0044] Add tembotrione 0.6%, sulfentrazone 1.8%, isoproturon 6.3%, 1% wetting agent EFW, 7% dispersant NNO, 0.5% binder CMC, 20% sodium sulfate, kaolin to 100% Put it into a mixing tank and mix it evenly, then airflow pulverize to obtain a powder, then add water to knead and granulate and dry to obtain 8.7% tembotrione.sulfentrazone.isoproturon (0.6:1.8:6.3) granules.

Abstract

The invention discloses a synergistic herbicidal composition, which comprises three effective components, namely tembotrion, sulfentrazone and isoproturon at the mass ratio of (0.5-1.2):(1-5):(1-10), wherein the sum of the three effective components in the composition is 1-60%. The herbicidal composition is suitable for preventing and killing most of gramineous weeds and broadleaf weeds in paddy fields, especially has a good prevention and treatment effect on lecrsia oryzoides, paspalum distichum and green-stem barnyard grass, and is long in lasting period, convenient to use and safe to rice.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a herbicidal composition. Background technique [0002] Tembotrione, chemical name 2-{2-chloro-4-methylsulfonyl-3-[(2,2,2-trifluoroethoxy)methyl]benzoyl}cyclohexane-1 , 3-diketone is a triketone cornfield herbicide developed by Bayer in 2007. It is mainly used in cornfields and is a post-emergent HPPD (p-hydroxyphenylpyruvate dioxygenase) inhibitor herbicide. Block the biosynthesis of prenyl quinone in plants, causing chlorosis, discoloration, tissue necrosis, and finally death within 2 weeks. Teratrione has a wide weeding spectrum and a long suitable period for weeding. It mainly controls various broad-leaved weeds and grass weeds in the middle and late stages of corn fields after budding. It is one of the most important herbicides used in corn fields in the United States because of its excellent control effect, no phytotoxicity to subsequent crops, and strong resistance to...
