Embodiment 1

[0015] Example 1 of the preparation method: 60% metafentrazone-propargyl oxadiazone wettable powder.

[0016] The following materials are coarsely pulverized according to the proportion, then put into the mixer and mixed evenly, and then after 2 times of jet pulverization, the 60% metafentrazone-propargyl oxadiazone wettable powder can be obtained.

[0017]

[0018] Preparation Method Example 2: 40% Metrafentrazone-Oxadiazone Propyril Suspension Concentrate.

[0019] The following materials are pre-crushed according to the proportion, and then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 40% mesafenac-propargyl oxadiazone suspension concentrate.

[0020]

Embodiment 3

[0021] Preparation Method Example 3: 80% Metrafentrazone·Oxadiazone Propyril Water Dispersible Granules.

[0022] Weigh the following formula in proportion, pour it into a mixer and mix it evenly, grind it through a jet mill for 3 times, granulate, dry, and sieve to prepare 80% mesafenac-propargyl oxadiazone water-dispersible granules agent.

Abstract

A weeding composition containing metazachlor and oxadiargyl is disclosed. The weeding composition comprises an effective component metazachlor and an effective component oxadiargyl, with the balance being pesticide auxiliary agents. The weight ratio of the metazachlor to the oxadiargyl is 1:30-20:1. The sum of the weight of the metazachlor and the weight of the oxadiargyl is 20-80% of the weight of the composition. According to pesticide processing technologies at present, the weeding composition can be prepared into wettable powder, suspensions, and water dispersible granules, and is used for annual weed control in potato fields. Effects of the weeding composition are obviously superior to effects of the metazachlor or effects of the oxadiargyl. The weeding composition expands the weeding range, saves time and labor and reduces the pesticide using amount.

Description

technical field [0001] The invention relates to a composition for preventing and controlling weeds in potato fields, which uses metafentrazone and oxadiazone propargyl as herbicidal active ingredients. Background technique [0002] Mezachlor is an acetanilide herbicide, which is mainly absorbed by weed shoots and young secondary roots, inhibits protein synthesis in the body, makes weed young plants swell, deformed, dark green in color, and eventually leads to death. It can be used to control grass weeds that germinate from seeds, annual sedges and some annual broadleaf weeds. [0003] Propyryl oxadiazone heterocyclic selective pre-emergence and post-emergence herbicide herbicide, the action is caused by the contact and absorption of the weed sprouts or seedlings with the agent, and the application of the drug after the emergence, the weeds are absorbed through the above-ground part, and the agent enters The plant body accumulates in the vigorous growth part, inhibits the gr...
