Garden nursery weed killer and use method thereof

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.
