Abstract

The invention discloses a weed killer for preventing and killing weeds in a wheat field. The weed killer consists of 3,7-dichloroquinoline-8-carboxylic acid or salt of the 3,7-dichloroquinoline-8-carboxylic acid, which serves as an active ingredient, and a pesticide aid, wherein the mass content of the active ingredient is 1-95 percent. The weed killer for preventing and killing the weeds in the wheat field particularly has a remarkable effect of preventing and killing barnyard grass in the wheat field, and can be used for preventing and killing noxious weeds such as digitaria sanguinalis, eclipta prostrate and setaria viridis.

Description

technical field [0001] The invention relates to the field of agricultural herbicides, in particular to a herbicide containing 3,7-dichloro-8-quinoline carboxylic acid or its salt and its application in weeding in wheat fields. Background technique [0002] Wheat crops are one of the most important food crops in our country. It is related to the feeding problem of our country's 1.3 billion people, and it is also a major issue related to social stability. In recent years, with the development of science and technology, herbicides have been widely used in wheat production, such as tribenuron-methyl, thifensulfuron-methyl, isoproturon, bromoxynil, fenoxaprop-ethyl, etc., for my country has made a significant contribution to the high yield and harvest of wheat production. However, due to the limitation of the weeding spectrum of these herbicides, the grass phase of the wheat field has changed significantly, and grass weeds have risen to become the main weeds, especially barnyardg...
