Abstract

The invention discloses a quizalofop-p-ethyl, nicosulfuron and atrazine composite environment-friendly emulsifiable concentrate. The quizalofop-p-ethyl, nicosulfuron and atrazine composite environment-friendly emulsifiable concentrate comprises the following components in percentages by weight: 1-25% of quizalofop-p-ethyl, 1-10% of nicosulfuron, 1-20% of atrazine, 1-25% of emulsifier, 1-20% of addition agent and the balance of solvent. The preparation method comprises the following steps: firstly weighing the quizalofop-p-ethyl, the nicosulfuron and the atrazine in a proportion, then adding the addition agent and the emulsifier after the quizalofop-p-ethyl, the nicosulfuron and the atrazine are sufficiently dissolved by using an environment-friendly solvent, and sufficiently and uniformly stirring. The preparation method is simple, the storage and using safety is extremely high, the prevention range of the preparation is enlarged, the biological activity is improved, and the emulsifiable concentrate is environment-friendly and accords with the development direction of current pesticide formulations.

Description

technical field [0001] The invention relates to a compound pesticide, in particular to a compound environment-friendly emulsifiable concentrate of quizalofop-p-ethyl, nicosulfuron-methyl and atrazine. Background technique [0002] Quizalofop-p-ethyl (Quizalofop-p-ethyl), also known as Jinghe grass, its chemical name is ethyl R-2-[4-(6-chloro-2-quinoxalineoxy)phenoxy]propionate , a phenoxycarboxylate herbicide. Quizalofop-p-ethyl is a herbicide with high efficiency and low toxicity. It is a highly selective new dry field stem and leaf treatment agent. It has high selectivity between grass weeds and dicotyledonous crops. Good control of weeds. [0003] Nicosulfuron was discovered by Ishihara Sangyo Co., Ltd. in Japan. It is a sulfonylurea systemic herbicide jointly developed with DuPont of the United States in the late 1980s. It can be absorbed by the stems, leaves and roots of weeds, and then in plants. Conduction can cause growth stagnation, greening of stems and leaves, ...
