Abstract

The invention relates to a synergistic herbicide as well as a preparation method and application thereof. The synergistic herbicide is prepared from the following components in percentage by weight: a first active component, a second active component, a synergist and an auxiliary material. The herbicide disclosed by the invention has a very good control effect on grassy weeds and broadleaf weeds such as adiantum capillus, eleusine indica, horseweed herb, malachium aquaticum, portulaca oleracea, rottboellia cochinchinensis, pennisetum purpureum, bidens pilosa and the like. According to the invention, two herbicides with different action mechanisms of contact killing and internal absorption are mixed and present complementary advantages, so a weeding rate is improved, a weed control spectrum is expanded, the time efficiency of weed control is prolonged, and the effective utilization rate of the herbicides is improved; and the added synergist can reduce the surface tension of a system and enhance performances such as spreadability, permeability and emulsification dispersibility, is beneficial to wetting, spreadability, adhesion and absorption of the liquid herbicides on the plant surface, promotes rain wash resistance, facilitates the absorption of weeds to the active components of the synergistic herbicide, improves the effective utilization rate of pesticides and reduces the use amount of the pesticides.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a synergistic herbicide and its preparation method and application. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. According to the function, it can be divided into killing herbicides and selective herbicides. The development of herbicides in the world has gradually stabilized, and pesticides with high efficiency, low toxicity, low dosage and environmental friendliness have gradually become the mainstream. [0003] Glyphosate ammonium salt targets 5-enolpyruvylshikimate-3-phosphate synthase in plant chloroplasts, inhibits plant shikimate metabolism pathway, and hinders the synthesis of aromatic amino acids required for plant cell synthesis, eventually lead to the death of the plant. Glyphosate has a strong systemic property. It c...
