Problems solved by technology

[0003] The main problem facing milk thistle chemical weeding at present is that the weeding effect is not good, and the phytotoxicity to milk thistle is serious, which seriously affects the yield
At present, beet Anning is mainly used as a post-emergence herbicide in milk thistle fields. If the herbicide is used at a low concentration, it will not kill weeds. If it is used at a high concentration, the silymarin will be seriously injured, and the herbicide has a narrow herbicidal spectrum. After many years of use, it has no effect on many weeds, such as chickweed, wild carrot, sorrel leaf Polygonum, artemisia, gray green quinoa and other weeds. Huge losses caused by large-scale planting

Embodiment 1

[0025] The composition of the present invention is a herbicidal composition containing flusulfuron-methyl and 2,4-D butyl ester, comprising the following components in parts by weight: 1 part of flusulfasulfuron-methyl, 1 part of 2,4-D butyl ester share.

[0026] Field efficacy test evaluation result of the composition of the present invention:

[0027]

[0028] The results of the field efficacy test showed that the combination had a good control effect on wild rape, Polygonum curcuma, Polygonum sorrel, Trichosanthes lentils, and quinoa in the milk thistle field, and it had a good effect on wild carrots and Artemisia weeds at the seedling stage. Better, the effect is worse when it is slightly larger, but it is also far better than the control effect of the control. There was very slight phytotoxicity to milk thistle in the early stage of application, but it was alleviated soon.

Embodiment 2

[0030] The composition of the present invention is a herbicidal composition containing flusulfasulfuron and 2,4-D, comprising the following components in parts by weight: 1 part of flusulfasulfuron and 0.9 part of 2,4-D.

[0031] Field efficacy test evaluation result of the composition of the present invention:

[0032]

[0033] The results of the field efficacy test showed that the combination had a good control effect on wild rape, Polygonum curcuma, Polygonum sorrel, Trichosanthes lentils, and quinoa in the milk thistle field, and it had a good effect on wild carrots and Artemisia weeds at the seedling stage. Better, the effect is worse when it is slightly larger, but it is also far better than the control effect of the control. There was very slight phytotoxicity to milk thistle in the early stage of application, but it was alleviated soon.

Embodiment 3

[0035] The composition of the present invention is a herbicidal composition containing flusulfasulfuron and 2,4-D isooctyl, comprising the following components in parts by weight: 1 part of flusulfasulfuron, 2,4-D isooctyl 0.8 part of ester.

[0036] Field efficacy test evaluation result of the composition of the present invention:

[0037]

[0038] The results of the field efficacy test showed that the combination had a good control effect on wild rape, Polygonum curcuma, Polygonum sorrel, Trichosanthes lentils, and quinoa in the milk thistle field, and it had a good effect on wild carrots and Artemisia weeds at the seedling stage. Better, the effect is worse when it is slightly larger, but it is also far better than the control effect of the control. There was a certain amount of phytotoxicity in the early stage of the application of milk thistle, which showed that the growth was slightly inhibited, and the leaf color was a little yellow, but it was relieved soon.

Abstract

The invention relates to the field of pesticide preparations, and discloses a silybum marianum chemical weeding composition. The silybum marianum chemical weeding composition consists of two chemicalcomponents, namely a compound A and triflusulfuron-methyl, wherein the compound A is phenoxy carboxylic acid and benzoic acid herbicides and comprises one or more of 2,4-D and esters, acids and saltsthereof, 2-methyl-4-chlorophenoxyacetic acid and sodium salt, amine salt, dimethylamine salt thereof, and dicamba. The silybum marianum chemical weeding composition is applied to post-emergence chemical weeding of silybum marianum, various weeds in a silybum marianum field can be effectively killed, the chemical weeding cost is effectively reduced, the pesticide effect is improved, no pesticide damage or little pesticide damage is caused to the silybum marianum, and the yield and quality of the silybum marianum are effectively improved.

Description

technical field [0001] The present invention relates to the technical field of pesticides, in particular to a milk thistle chemical herbicide composition, especially an active ingredient composed of flusulfasulfuron-methyl, phenoxycarboxylic acid and benzoic acid herbicides: including 2,4- A herbicidal composition composed of one or more of D and its esters, acids and salts, 2-methyl-4-chloride and its sodium salt, amine salt, dimethylamine salt, and dicamba. Background technique [0002] Milk thistle is an annual or biennial herb of the genus Milk thistle in the family Asteraceae. It is an excellent liver-protecting plant. The whole plant is used for carbuncle and erysipelas. Lower blood fat, protect heart muscle, protect brain, anti-X-ray function, have good curative effect on acute and chronic hepatitis, liver cirrhosis, fatty liver, liver injury caused by metabolic toxicity, cholelithiasis, cholangitis and perihepatic cholangitis and other hepatobiliary diseases .
