Embodiment 1

[0026] Embodiment 1: 50% water suspension concentrate

[0027] Formula (weight ratio): saflufenacil 10%, glyphosate 40%, dispersant NNO 10%, fatty alcohol polyoxyethylene ether 14%, ethylene glycol 6%, xanthan gum 3%, water supplement 100 %.

[0028] Preparation method: first dilute glyphosate with water, then add saflufenacil to obtain a mixed solution, then add auxiliary dispersant NNO, ethylene glycol and fatty alcohol polyoxyethylene ether, grind and mix with xanthan gum, High-speed shearing and mixing to obtain a water-suspension dosage form.

Embodiment 2

[0029] Example 2: 45% water dispersible granules

[0030] Formula (weight ratio): saflufenacil 20%, glyphosate 25%, sodium dodecylbenzene sulfonate 18%, fatty alcohol polyoxyethylene ether dispersant 15%, sodium sulfate 4%, clay 10% , bentonite makes up 100%.

[0031] Preparation method: Mix glyphosate, saflufenacil, additives, etc., pulverize through an airflow mill, enter into an extrusion granulator to granulate, and dry in a fluidized bed dryer to obtain a water-dispersible granule dosage form. .

Embodiment 3

[0032] Example 3: 32% dispersible oil suspension concentrate

[0033] Formula (weight ratio): saflufenacil 2%, glyphosate 30%, sodium lignosulfonate 10%, YUS-110 emulsifier 12%, ethylene glycol 3%, xanthan gum 1%, epoxy Soybean oil 2%, silicone oil 1%, vegetable oil (soybean oil) to make up to 100%.

[0034] Preparation method: Weigh saflufenacil and glyphosate into a container, add emulsifier, dispersant and soybean oil, mix and disperse at high speed, then use a sand mill to grind, and filter to obtain the available Dispersed oil suspension formulation.

Abstract

The invention relates to the technical field of pesticides, in particular to a herbicidal composition. In parts by weight, the herbicidal composition is composed of 0.1-90 parts by weight of saflufenacil and 1-100 parts by weight of glyphosate. The invention is a herbicide composition with high cost performance, low toxicity and high efficiency, which can effectively prevent and control harmful weeds when applied to cultivated land or non-cultivated land.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound herbicidal composition containing saflufenacil and glyphosate. Background technique [0002] In recent years, with the gradual increase in the requirements for creating new pesticide compounds, the cost of developing new compounds for registration applications is getting higher and higher. In compliance with the policies of high efficiency, low toxicity, selectivity, and safety and saving drug costs, through the existing Reasonable screening and recombination of some compounds is an effective way to solve this problem. [0003] Saflufenacil, other names: Babaijin, molecular formula: C 17 h 14 CIF 4 N 4 o 5 S, chemical name: N'-[2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydro-1( 2H)-pyrimidine)benzoyl]-N-isopropyl-N-methylsulfamide. Saflufenacil is a herbicide that can kill more than 70 kinds of weeds on more than 30 kinds of crops, suc...
