Embodiment 1

[0027] The wettable powder containing diflufenican and oxadiazone in this embodiment has the following components and weight content:

[0028] Diflufenamide 20%

[0029] Oxadiazone 35%

[0030] Surfactant 11%

[0031] Filler 34%

[0032] The surfactant in this embodiment is a mixture of dispersant and wetting agent. The dispersant is calcium lignosulfonate, with a content of 9%; the wetting agent is sodium lauryl sulfate, with a content of 2%; the filler is white carbon black and kaolin, of which the white carbon black content is 10%, and the kaolin content is 24% .

[0033] The production method of the wettable powder containing diflufenamide and oxadiazone in this example is as follows: add the active ingredients diflufenamide and oxadiazone into the filler, add a surfactant to it, and mix in a mixer Finally, it is pulverized by a jet mill, and then mixed evenly in a mixer.

Embodiment 2

[0035] The difference between this embodiment and embodiment 1 is: its component and weight content are:

[0036] Diflufenamide 30%

[0037] Oxadiazone 40%

[0038] Surfactant 12%

[0039] Filler 18%

[0040] The surfactant in this embodiment is a mixture of dispersant and wetting agent. The dispersant is alkyl naphthalene sulfonate formaldehyde condensate, the content is 9%; the wetting agent is sodium lauryl sulfate, the content is 3%; the filler is attapulgite.

Embodiment 3

[0042] The difference between this embodiment and embodiment 1 is: its component and weight content are:

[0043] Diflufenamide 20%

[0044] Oxadiazone 20%

[0045] Surfactant 5%

[0046] Filler 55%

[0047] The surfactant of this embodiment is the mixing of dispersant and emulsifier. The dispersant is polycarboxylate, with a content of 4%; the emulsifier is Nongru OP-10, with a content of 1%; the filler is diatomite and bentonite, of which the content of diatomite is 20%.

Abstract

The invention belongs to the field of pesticides and herbicides, and in particular relates to wettable powder containing diflufenican and oxadiazon and a production method of the wettable powder. The wettable powder contains the following ingredients in content by weight: 1-30 percent of diflufenican, 1-60 percent of oxadiazon, 5-20 percent of surfactant, and 10-80 percent of filler; and the total weight content of all the ingredients is 100 percent. The composition is mainly used for controlling annual broadleaf weeds and gramineous weeds in garlic, wheat and paddy fields. The composition has the characteristics of synergistic effect, expansion in herbicidal spectrum, delay in herbicide resistance and low cost.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to a wettable powder containing diflufenican and oxadiazone and a production method thereof. Background technique [0002] Diflufenican belongs to carotenoid biosynthesis inhibitors and is a broad-spectrum selective wheat field herbicide, which causes chlorophyll damage, cell rupture, and plant death. Apply 125-250g / ha pre-emergence or post-emergence to wheat and barley fields in autumn to control gramineous and broad-leaved weeds, especially weeds such as pig's weeds, porcini and viola. The agent has the following characteristics: wide herbicide spectrum; can control malignant weeds; long efficacy period in the soil; stable efficacy; can be mixed with other herbicides to expand the herbicide spectrum. [0003] Oxadiazone, also known as oxadiazone and Nongsita, is a selective pre-emergence and post-emergence herbicide. It is mainly absorbed through weed buds or stems and...
