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

The invention discloses a herbicidal composition containing mefentrazone and clomazone propargyl, the herbicidal active ingredients are mefentrazone and clomazone propargyl, and the rest are pesticide adjuvants; The mass ratio of clomazone is 1:30 to 20:1, and the mass percentage of the sum of the mass of metafentrazone and clomazone in the composition is 20% to 80%; according to the existing pesticide processing technology , the present invention can be prepared into wettable powder, suspending agent, water dispersible granule, used for controlling annual weeds in potato fields. The effect of the present invention is obviously better than that of mefentrazone or propargyl clomazone, and the herbicide spectrum is expanded, time and labor are saved, and the dosage of medicine is reduced.

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...
