Embodiment 1

[0012] Example 1: Indoor Determination of Weeds Compounded by Metrazone, Mesotrione and Atrazine

[0013] Drugs to be tested: the original drug of fenfentrazone, the original drug of mesotrione, and the original drug of terbuthylazine; all are commercially available.

[0014] Weeds to be tested: Gramineae weeds are crabgrass and goosegrass; weed seeds are collected in the test field.

[0015] experiment method:

[0016] Pharmacy preparation Weigh a certain amount of original drug according to the dose required for the test, first dissolve it with a small amount of acetone, prepare a high-concentration mother solution, store it in a refrigerator at 0-4°C, and then use Tween 80 with a mass fraction of 0.1% for the test. The aqueous solution was diluted to the required concentration, and the 0.1% Tween 80 aqueous solution with the addition of an equal amount of acetone but no fenflumezone and medicament was used as a blank control. Prepare the mixture of the two agents in the s...

Embodiment 2

[0029] Embodiment 2 field drug effect determination

[0030] Test medicament: 35% fenflumezone·mesotrione·terbuthylzine suspension concentrate (oxentrazone 3%, mesotrione 10%, terbuthylzine 22%, Nongru 1601 5%, Nongru 2201 7%, NNO 2%, magnesium aluminum silicate 4%, ethylene glycol 2%, sodium benzoate 3%, bentonite 4%, deionized water to make up 100%. According to the conventional method, it is configured to contain fenflumezone , The amount is 30% suspending agent.

[0031] Experimental crops: corn field, field weeds: barnyardgrass, crabgrass goosegrass, purslane.

[0032] Application method: Set up 2 chemical treatments, 1 blank control, and repeat 3 times; the area of ​​each plot is 40m2, arranged randomly. Spray the stems and leaves with a sprayer. 21 days after spraying, the fresh weight control effect of weeds was investigated.

Abstract

The invention provides a weeding composition containing topramezone, mesotrione and terbuthylazine, the active ingredients of the weeding composition comprise topramezone, mesotrione and terbuthylazine, and the mass ratio of topramezone to mesotrione to terbuthylazine is (5-15):(40-60):(110-330). The weeding composition disclosed by the invention can be used for preventing and removing annual weeds in a crop field and has a remarkable synergistic effect.

Description

technical field [0001] The invention belongs to the field of herbicides, and in particular relates to a herbicidal composition comprising fentrazone, mesotrione and terbuthylazine and an application thereof. Background technique [0002] Oxentrazone is a systemic herbicide that can be absorbed by leaves, roots and stems of plants. It has a broad herbicidal spectrum and can control annual grass and broad-leaved weeds: crabgrass, barnyardgrass, goosegrass, foxtail, wild millet, pigweed, polygonum, velvetleaf, amaranth, ragweed, mangosteen Tuoluo, Achyranthes chrysanthemum, purslane, cocklebur, nightshade, etc. Mesotrione is a hydroxyphenylpyruvate dioxygenase inhibitor, a herbicide for stem and leaf treatment with a unique mechanism of action, and can be used to control broad-leaved weeds and some grass weeds: retroflexus, purslane, Chenopodium, Polygonum, Commelina, Barnyard Grass, Crabgrass, etc. Terbutyzine is a triazine selective systemic conduction herbicide, which is ...
