Problems solved by technology

[0002] Glyphosate is a high-efficiency, low-toxicity, low-residue broad-spectrum herbicide, but due to the long-term use of glyphosate single agent, some weeds have obvious resistance, and the control effect on some perennial vicious weeds It is common that weeds are not completely killed, the roots are not killed, or the weeds turn green and survive after a period of time, which increases the amount of glyphosate used per unit area and the number of times of use, and the cost of use increa

Example Embodiment

[0015] Example 1:

[0016] Combine 785 g of glyphosate with a purity of 95%, 5 g of acifluorfen with a purity of 95%, 10 g of isooctyl fluoride with a purity of 95%, 20 g of sodium lauryl sulfate, and modified poly Carboxylic acid salt (LBD-1) 50g, naphthalene sulfonate (dispersant NNO) 10g, ammonium sulfate supplemented 1000g, and ultrafine grinding. Then the weightless mixing is carried out in a pear knife type non-gravity mixer. During the mixing process, 100g of tap water is added by spraying. This process is about 5-10 minutes, and then the rotating side extrusion granulation is carried out, and then the fluidized bed dryer Dry at 70-105°C to obtain white particles with a particle size of 0.5-1.5 mm, which are the dispersible granules composition of 76% glyphosate, isooctyl cloflurane and carboxifen. All percentages in this embodiment are mass percentages.

Example Embodiment

[0017] Example 2

[0018] 842g of glyphosate ammonium salt with a purity of 95% (containing 800g glyphosate), and a purity of 95% carboxifen 5 . 26g (containing 5g of acifluorfen), 95g of isooctyl cloflufenox, 35g of sodium naphthalene sulfonate (NNO), 1000g of white carbon black, and superfine grinding. Then, the weightless mixing is carried out in a pear knife-type weightless mixer, and the wettable powder composition of the present invention contains 90% glyphosate ammonium salt, isooctyl cloflufenox, and fluorfen. All percentages in this embodiment are mass percentages.

Example Embodiment

[0019] Example 3

[0020] 811 g of glyphosate ammonium salt with a purity of 95% (glyphosate 737g), a purity of 10.5 g of acifluorfen 95%, 49.5 g of isooctyl ester of 95% fluroxypyr and 30 g of sodium pyrophosphate , Sodium lauryl sulfate 20g, modified polycarboxylate (TERSPERSE 2700) 50g, naphthalene sulfonate (dispersant NNO) 10g, sodium sulfate to make up 1000g, and superfine pulverization. Then the weightless mixing is carried out in a pear knife type non-gravity mixer. During the mixing process, 100 g of tap water is added by spraying. This process is about 5-10 minutes, and then the rotating side extrusion granulation is carried out, and then the fluidized bed dryer Dry at 70-105°C to obtain white particles with a particle size of 0.5-1.5 mm, which are the dispersible granules composition of 75.7% glyphosate, isooctyl cloflurane and fluorfen. All percentages in this embodiment are mass percentages.

Abstract

The invention provides a herbicide, which concretely comprises the following components in mass percent: 30%-80% of phosphonomethyl imino acetic acid, 0.5%-20% of fluoroglycofen-ethyl, 1%-10% of fluroxypyr-mepthyl, 3%-20% of surfactant, and the balance of carriers or accessories. According to the invention, the herbicide has stable properties and a reasonable formula; and the herbicide containing 40%-90% of effective components including wettable powder (WP), suspension concentrate (SC), oil deflocculant (OD), water-dispersible granules (WDG) and emulsifiable powder (WEP) can be prepared by production methods of common pesticide preparations. The herbicide provided by the invention can be used for preventing and eradicating weeds in forest lands, non-tillage fields and wastelands, and has an excellent control effect on weeds with resistance to phosphonomethyl imino acetic acid.

Description

Technical field [0001] The invention involves a composition of a chemical agent, which specifically involves a herbicide. Background technique [0002] Green oligurp is a high -efficiency, low toxic, low -residue wide -spectrum exterior herbicide, but due to the long -term use of grass glyphosate, some weeds have obvious resistance, and some perennial malignant weeds are used.Decreased, the phenomenon of incomplete grass killing, not killing the roots, or taking the medicine for a period of time, which increases the amount and use of the unit area of the glyphosate, increased the cost of use at the same time, and the multiple reuse of multiple times has also increased.The risk of the residue of glyphosate in the crops is not in line with the guidelines for the use of pesticides and the development of agricultural development. At present, domestic use of glyphosate or binary complex composition is used to increase the forest land, increase the forest land,Weeds such as non -cultiv...
