Abstract

The invention relates to the field of crop herbicides, and in particular relates to a compound synergistic herbicide and a preparation technology thereof. The compound synergistic herbicide comprises active components and auxiliary materials in a pesticide preparation, wherein the active components comprise a glyphosate type compound and diquat; the weight ratio of the glyphosate type compound to diquat ranges from 1.5:1 to 25:1. The herbicide is water aqua which comprises the following components in percentage by weight: 25-50 percent of ammonium glyphosate, 1-20 percent of diquat, 3-15 percent of a surfactant, 0-0.1 percent of a vomitive, 0.1-1 percent of alert pigment, 3-10 percent of a synergist and the balance being a solvent. By compounding of the herbicide, the prevention and treatment spectrum can be expanded, the weeding speed is increased, and the prevention effect is enhanced; furthermore, the drug resistance is delayed, and the existing drug resistance is treated.

Description

Technical field: [0001] The invention relates to the field of crop herbicides, in particular to a compound synergistic herbicide and a preparation process thereof. Background technique: [0002] There are many kinds of weeds in non-cultivated land, and herbicides are the main control measures. Diquat is a bipyridine herbicide. It is a quick-acting contact-killing herbicide. It can be quickly absorbed by green plant tissues and quickly loses its activity after contacting with the soil. It can be used for weeding in fields, orchards, non-cultivated land, and before harvesting. It can also be used as stems and leaves of potatoes and sweet potatoes to wither. It is also a widely used aquatic weed herbicide abroad. When it is used in the field, it is often used to kill the grown grass before and after the crops are sown and before the seedlings, or to use inter-row directional spraying after the crops grow up. At the same time, Diquat is also a contact desiccant, which can be ...
