Problems solved by technology

In recent years, due to the large-scale use of some herbicide varieties alone, 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 of them will show some defects and problems. limitation

Embodiment 1

[0033] Preparation Example 1: (40% glufosinate-ammonium saflufenacil suspension concentrate):

[0034] Glufosinate-ammonium 30%,

[0035] Saflufenacil 10%,

[0036] Farm Milk 1601#15%,

[0037] p-Oleamidoanisole Sulfonic Acid 5%,

[0038] Alkylphenol Formaldehyde Resin Polyoxyethylene Ether Sulfate 4%,

[0039] Bentonite 3%,

[0040] Xanthan gum 0.1%,

[0041] Silicone 0.4%,

[0042] Glycerol 4%,

[0043] Make up to 100% with deionized water.

[0044] The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and mixed by high shear to prepare a 40% glufosinate-saflufenacil suspension concentrate.

Embodiment 2

[0045] Preparation example two: (40% glufosinate-ammonium saflufenacil oil suspension concentrate):

[0046] Glufosinate-ammonium 30%,

[0047] Saflufenacil 10%,

[0048] Vegetable oil 30%,

[0049] Bentonite 1%,

[0050] Methylated vegetable oils make up to 100%.

[0051] Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase; mix under high-speed stirring to prepare 40% glufosinate-saflufenacil oil suspension concentrate.

Embodiment 3

[0052] Formulation example three: (50% glufosinate-ammonium saflufenacil water-dispersible granules):

[0053] Glufosinate-ammonium 40%,

[0054] Saflufenacil 10%,

[0055] Sodium Lauryl Sulfate 4%,

[0056] Polycarboxylate 4%,

[0057] Urea 35%,

[0058] Kaolin to 100%.

[0059] Put the above materials together into the conical mixer and mix evenly, and then pulverize through the jet mill, and then mix the pulverized materials through the conical mixer. Knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate. After granulation, dry and sieve to obtain 50% glufosinate-saflufenacil water-dispersible granules.

Abstract

The invention discloses a herbicidal composition containing glufosinate-ammonium and saflufenacil. The composition comprises active components of glufosinate-ammonium, and saflufenacil, and the balance of pesticide adjuvants. Glufosinate-ammonium and saflufenacil in the herbicidal composition are in a weight ratio of 50:1-1:10, and the total weight of glufosinate-ammonium and saflufenacil accounts for 2-80 wt% in the herbicidal composition. The herbicidal composition can be prepared into one of the followings: a suspension agent, an oil suspension agent, a water agent, a wettable powder and a water dispersion granule, according to the application requirements, and can be applied to control of weeds in no-crop field. The composition has control effect on weeds in no-crop field better than that of each single agent, and can reduce the dosage and delay drug resistance of weeds.

Description

technical field [0001] The invention relates to a composition containing glufosinate-ammonium and saflufenacil, which is used as active ingredients for preventing weeds in non-cultivated land. 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] Glufosinate-ammonium, also known as Butafosin, Besuton, English common name: glufosinateammonium, chemical name: 2-amino-4-[hydroxy (methyl) phosphono] ammonium...
