Abstract

The present invention discloses a garden nursery weed killer, which comprises the following raw materials by weight: 20-40% of metolachlor, 10-20% of pendimethalin, 2-8% of oxyfluorfen, and 43-58% of an auxiliary agent, wherein the use of the garden nursery weed killer can adopt preemergence spraying or postemergence killing. According to the present invention, the garden nursery weed killer adopts the vegetable oil as the solvent so as to provide characteristics of no pollution, neutral and slightly acidic pH value, excellent stability and good buffer property; the garden nursery weed killer does not contain harmful metals and hormone substances, such that the use is safe; the characteristic that the agent is only fixed on the surface soil layer (about 1-2 cm) and is not leached into the deep layer is adopted, such that the weed seeds capable of germinating in the surface soil layer are killed or inhibited, and the crop seeds can normally sprout and grow due to protection of the soil covering layer; and with the garden nursery weed killer, normal growth of crops can be ensured, the persistent period on the sandy soil ground can achieve 35-40 days, the persistent period on the clay ground can achieve 60-70 days, and 2-4 leaf stage weeds can be killed after sowing and seedling emergence.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a garden nursery herbicide and a use method thereof. Background technique [0002] Herbicides, also known as herbicides, are substances used to destroy or inhibit the growth of plants. The action is affected by three factors: herbicide, plant and environmental conditions. According to the function, it can be divided into killing and selective herbicides, and the commonly used varieties are organic compounds. It can be widely used to prevent and control harmful plants such as weeds, shrubs, and trees in farmland, orchards, flower nurseries, grasslands and non-cultivated land, railway lines, rivers, reservoirs, warehouses, etc. [0003] Herbicides are agents that can completely or selectively kill weeds. Sodium chlorate, borax, arsenic acid, trichloroacetic acid have a deadly effect on any kind of vegetation, but because of their residual effects, they should not be used in t...
