Example Embodiment

[0039] Example 1: 30% propinyl pendimethalin wettable powder.

[0040]

[0041] The above formula is coarsely pulverized according to the proportion and then enters into a mixer to mix evenly, and then is pulverized by airflow to obtain 35% propinyl pendimethalin wettable powder.

Example Embodiment

[0042] Example 2: 70% propinyl pendimethalin water dispersible granules.

[0043]

[0044] Weigh the above formula in proportion and pour it into a mixer to mix evenly, grind it 3 times with a jet mill, granulate, dry and sieving to prepare 70% propinyl propinyl pendimethalin water dispersible granules .

Example Embodiment

[0045] Example 3: 30% propinyl pendimethalin water emulsion.

[0046]

[0047]

[0048] The above formula is weighed in proportion and poured into a mixer to mix evenly, and a 30% propinyl pendimethalin water emulsion is prepared through high-speed shear emulsification.

Abstract

The invention discloses an herbicidal composition applicable to a potato field. The herbicidal composition contains cyclo-oxadiargyl and pendimethalin which serve as active ingredients, wherein a ratio of cyclo-oxadiargyl to pendimethalin is equal to (1:20) to (20:1) in parts by mass, and the total mass of cyclo-oxadiargyl to pendimethalin accounts for 20%-80% of the mass of the composition. Depending on application demands, the herbicidal composition disclosed by the invention can be prepared into water dispersible granules, wettable powder, an emulsion in water or in other application dosage forms applicable to agricultural use; the herbicidal composition is suitable for preventing and removing annual weeds of the potato field, and has a weeding effect significantly better than that of single cyclo-oxadiargyl or single pendimethalin; a weed controlling spectrum is widened, a dosage is reduced and disease resistance of weeds is delayed.

Description

technical field [0001] The invention relates to a potato field herbicide, which uses the combination of propargyl oxadiazone and pendimethalin as active ingredients, and the rest as auxiliary agents. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all will show some defects and limitation. Mixing different types of herbicides has the advantages of broad herbicidal spectrum, improving the actual effect, delaying weed resistance, and saving time and labor. [0003] Propyryl oxadiazone acts through weed sprouts or seedlings contacting and absorbing the drug. The drug is a high-efficiency, broad-spectrum rice field he...
