Problems solved by technology

[0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth, among which sodium chlorate, borax, arsenate, trichlor Acetic acid has a deadly effect on any kind of plant. Its effect is affected by three factors: herbicide, plant and environmental conditions. According to its effect, it can be divided into killing and selective herbicides. Most of the derivatives of phenol and carbamic acid are effective. The development of herbicides in the world is gradually stabilizing. The main development is the varieties with high efficiency, low toxicity, broad spectrum and low dosage. It is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. Mixed weeds, herbs, vines and shrubs, and the emergence of weeds is uneven, and seeds, young and old weeds occur alternately, so when the herbicide species are used alone, they will show some defects and limitations

Embodiment 1

[0017] Wettable powder:

[0018] The active ingredients are composed of the following raw materials and their parts by weight: 32% quinclorac, 28% thiopyridione, 40% promethazone-methyl, 0.01% isostearate, 0.05% isopropyl isostearate %.

[0019] After the above formula is roughly pulverized in proportion, it is mixed with kaolin in a mixer at a ratio of 1:2, and then jet pulverized to obtain a wettable powder of the herbicide composition.

Embodiment 2

[0021] Suspoemulsion:

[0022] The active ingredient consists of the following raw materials and their parts by weight: 30% quinclorac, 30% thiopyridione, 40% promethazone-methyl, 0.03% isostearate, 0.05% isopropyl isostearate %.

[0023] Dissolve quinclorac in N-methylpyrrolidone, add sodium p-methoxy fatty amidobenzenesulfonate to obtain an oil phase; Sodium phenyl sulfonate, alkylphenol polyoxyethylene ether formaldehyde condensate sulfate, and water are ground and / or high-speed sheared to obtain saflufenacil water suspension; add the oil phase to the water phase under stirring to obtain Suspoemulsion.

Embodiment 3

[0025] Water-dispersible granules:

[0026] The active ingredient consists of the following raw materials and their parts by weight: 30% quinclorac, 30% thiopyridione, 40% promethazone-methyl, 0.01% isostearate, 0.05% isopropyl isostearate %.

[0027] The above formula is mixed with kaolin at a ratio of 1:1, dry crushed, granulated, dried, and sieved to prepare water-dispersible granules of the herbicide composition.

Abstract

The invention relates to a weedicide composition and application of the weedicide composition and in particular relates to a ternary compound weedicide composition applied to a farmland. The weedicide composition is prepared from the following effective components: quinclorac, thiapyrandiketone, propyrisulfuron, isostearate, isopropyl isostearate, and a surfactant or a filling agent. The weedicide composition provided by the invention has the advantages that the weeding effect of the weedicide composition is better than that of single-component weedicide; the weedicide composition provided by the invention has a more rapid weeding effect; the weedicide composition does not generate an increasing effect, which cannot be accepted, on the toxicity on plants and the influences on the environment are very small; the weedicide has a wide applicable range, a manufacturing process is extremely simple and the weedicide is suitable for large-area popularization.
