Embodiment 1

[0031] The isoproturon, chlorotoluron, tribenuron-methyl and leveling agent are mixed according to 100 parts by weight, 75 parts by weight, 3 parts by weight and 10 parts by weight respectively to prepare a wettable powder compound that can be used in wheat fields. At the 2-4 leaf stage of wheat seedlings, according to the total active ingredients of the herbicide, 90-125g of the herbicide is used to dilute with water, and then the stems and leaves are sprayed. The treatment effects are reflected in Table 1 above. The leveling agent is Pingping plus O-25.

Embodiment 2

[0033] The isoproturon, chlorotoluron, tribenuron-methyl and leveling agent are mixed according to 100 parts by weight, 65 parts by weight, 4 parts by weight and 6 parts by weight respectively to prepare a wettable powder compound that can be used in wheat fields. At the 2-4 leaf stage of wheat seedlings, according to the total active ingredients of the herbicide, 90-125g of the herbicide is used to dilute with water, and then the stems and leaves are sprayed. The leveling agent is Pingping plus O-25.

Embodiment 3

[0035] The isoproturon, chlorotoluron, tribenuron-methyl and leveling agent are mixed according to 100 parts by weight, 85 parts by weight, 2 parts by weight and 13 parts by weight respectively to prepare a wettable powder compound that can be used in wheat fields. At the 2-4 leaf stage of wheat seedlings, according to the total active ingredients of the herbicide, 90-125g of the herbicide is used to dilute with water, and then the stems and leaves are sprayed. The leveling agent is Pingping plus O-25.

Abstract

The invention discloses a wheat field compounded herbicide, which consists of isoproturon, chlortoluron, tribenuron-methly and a leveling agent. The wheat field compounded herbicide can effectively control the weed problems in the whole growing period of the wheat field.

Description

Technical field: [0001] The present invention relates to a herbicide. Background technique: [0002] For a long time, weed damage has always been a major problem for wheat production. Manual weeding is not only labor-intensive, but also unrealistic in actual production. Therefore, chemical weeding has become the most economical and effective way to control weeds in wheat fields. [0003] Weeds in wheat fields can be roughly divided into two categories, one is gramineous weeds, mainly including Aurantia, Hardweed, Bluegrass, etc.; the other is dicotyledonous weeds, mainly including pig weed , shepherd's purse, mother-in-law and so on. [0004] In current production, herbicides such as isoproturon, chlortoluron and fenoxaprop-p-ethyl are commonly used to prevent and control grass weeds in wheat fields, and tribenuron-methyl, tribenuron-methyl, Fluroxypyr is used to control dicotyledonous weeds in wheat fields, and compound agents such as isoproturon and tribenuron-methyl a...
