Embodiment 1

[0092] Example 1 1% Ametryn + 50% Sulfentrazone Water Dispersible Granules

[0093] Aramet 1%

[0094] Sulfentrazone 50%

[0095] Sodium lignosulfonate 5%

[0096] Sodium Lauryl Sulfate 2%

[0097] Urea 10%

[0098] Kaolin topped up to 100%

[0099] The active ingredient, dispersant, wetting agent, disintegrant, co-solvent and filler are mixed evenly according to the ratio of the formula, crushed into a wettable powder by airflow, and then a certain amount of water is added to mix and extrude to granulate. After drying and sieving, 1% ametryn + 50% sulfentrazone water dispersible granules were obtained.

Embodiment 2

[0100] Example 2 50% Ametraz + 10% Sulfentrazone WP

[0101] Atrazine 50%

[0102]Sulfentrazone 10%

[0103] Sodium Lauryl Sulfate 2%

[0104] Sodium lignosulfonate 15%

[0105] Silica 5%

[0106] Kaolin supplemented to 100%

[0107] Mix the active ingredients, various additives and fillers according to the ratio of the formula, and pulverize them with an ultra-fine pulverizer to obtain 50% ametryn + 10% sulfentrazone wettable powder

Embodiment 3

[0108] Example 3 50% Ametraz + 1% Sulfentrazone Suspending Concentrate

[0109] Atrazine 50%

[0110] Sulfentrazone 1%

[0111] Lignosulfonate 5%

[0112] Sodium dioctyl sulfosuccinate 0.5%

[0113] Fatty Alcohol Ethoxylates 3%

[0114] Xanthan Gum 0.3%

[0115] Glycerol 5%

[0116] Defoamer 0.6%

[0117] Water to make up to 100%

[0118] The active ingredient, dispersant, wetting agent and water are mixed uniformly according to the ratio of the formula, and after grinding and / or high-speed shearing, 50% ametryn + 1% sulfentrazone suspending concentrate is obtained. Components other than xanthan gum can also be mixed evenly according to the ratio of the formula, stirred and ground, and then mixed with the prepared 1% xanthan gum, stirred evenly to obtain 50% ametryn + 1% sulfentrazone suspension agent.

Abstract

The invention provides a weeding combination containing ametryn and sulfentrazone and applications of the weeding combination. The weeding combination comprises the ametryn and sulfentrazone which are taken as active substances. The invention also relates to a method for processing unexpected vegetations by using the weeding combination. The weeding combination containing the ametryn and the sulfentrazone is characterized by comprising the active components, namely the ametryn and the sulfentrazone, wherein the weight ratio of the ametryn to the sulfentrazone is 50: 1 to 1: 50. The ametryn and the sulfentrazone are 5 to 90% of the wedding combination by weight percent. The weeding combination is applied to places with vegetation or places expected to be free from vegetation. The weeding combination is mainly used for removing weeds in a sugarcane field, a corn field citrus orchard and the like, and particularly removing cyperus rotundus weeds.

Description

technical field [0001] The invention relates to a herbicidal composition containing ametryn and sulfentranacil and the application thereof, which includes ametryn and sulfentrazone as active substances. The invention also relates to methods of using said herbicidal compositions for the treatment of undesired vegetation. Background technique [0002] Protecting crops against weeds and other plants that inhibit crop growth is a recurring challenge in agricultural management. To help address these problems, researchers in the field of synthetic chemistry have produced a wide variety of chemicals and chemical formulations that are effective in controlling this unwanted growth. Many types of chemical herbicides are disclosed in the literature, and many types are commercially available. [0003] In some cases, herbicidally active ingredients appear to be more effective when applied in combination than when applied individually, a phenomenon known as "synergy" because the combina...
