Embodiment 1

[0026] Example 1. Wettable powder

[0027] When in the compound (b), R is Na, and X is Br, the active ingredient mixture of 40 parts by weight (4 parts by weight of bromoxynil sodium salt+36 parts by weight of mesotrione), 3 parts by weight Alkyl naphthalene formaldehyde condensate sodium sulfonate, 4 weight parts of sodium dodecylbenzene sulfonate, the glycerol of 0.4 weight part, 52.6 weight parts of kaolin are mixed, through superfine pulverization, make silt reach fineness requirement, The dosage form is prepared by using a double-screw mixer and a coulter mixer for multiple times of mixing to make the product evenly mixed.

Embodiment 2

[0028] Embodiment 2. Suspending agent

[0029] When in compound (b), R is H, and X is Br, 30 parts by weight of active mixture (11 parts by weight of bromoxynil+19 parts by weight of mesotrione), 11 parts by weight of woody Calcium Sulfonate, 4 parts by weight of carboxymethyl cellulose, 2 parts by weight of propylene glycol and 53 parts by weight of water, the mixture is obtained through main processes such as mixing, stirring and sand milling.

Embodiment 3

[0030] Embodiment 3. Suspending agent

[0031] When in compound (b), R is H, and X is when I, above suspending agent also can be made in the following manner: the active form mixture of 25 parts by weight (the methylsulfonic acid of the ioxynil of 9 parts by weight+16 parts by weight Grass ketone), 1.5 parts by weight sodium polyacrylate, 3.0 parts by weight propylene glycol, 14.0 parts by weight lignosulfonate, 5.0 parts by weight octylphenol polyethylene glycol ether (11-14 mole ethylene oxide), 51.5 parts by weight water.

Abstract

The invention discloses a weeding combination. The active components of the combination consist of a compound (a) and a compound (b). The compound (a) is mesotrione, and the compound (b) is a compound (I) which has the following structure characters, wherein, R is H, Na or K, and X is Br or I; the weight ratio of the compound (a) and the compound (b) is 1: 0.08-7. The invention further discloses an application of the weeding combination, the weeding combination is used for preventing and eliminating grassy weed and broadleaf in corn farmlands. The prevention effect of the combination is better than the activity in the separate application of the herbicide, and the combination can bring surprising enhancing effect, guarantee production rate of crops, is convenient in use, lowers the cost of application, expands prevention and cure of weeds, reduces the times of application and decreases labor intensity.

Description

technical field [0001] The present invention relates to a herbicidal composition having improved properties, in particular to a herbicide for controlling gramineous and broadleaf weeds in cornfields. Background technique [0002] At present, the main herbicides used to control field weeds after corn seedlings mainly include: amide herbicides, such as alachlor, acetochlor, etc. The efficacy of such herbicides is greatly affected by external climatic conditions, such as Influenced by soil moisture, the weeding effect is significantly reduced when the moisture is poor; Triazine herbicides: representative varieties are: cyanazine, simazine, these herbicides are mainly absorbed by the root system, and the residual effect period in the soil is long, It is not conducive to crop rotation and stubble, which not only affects the subsequent crops of cruciferous vegetables, but also causes a certain degree of phytotoxicity to the subsequent crops of wheat and soybeans; and among the ste...
