Embodiment 1

[0025] A kind of mixed herbicide composition that is used for sugar beet field, the weight percent of each following component is:

[0026]

[0027] Take the configuration of 1000kg of herbicide as an example: Weigh 200kg of memetrazone with a mass fraction of 100%, 50kg of ethofurazone with a mass fraction of 100%, 25kg of a dispersant, 10kg of an emulsifier, 4kg of a thickener, and Antifreeze 1kg, antifreeze 15kg, defoamer 1kg, water make up to 1000kg.

[0028] The preparation method of the sugar beet field mixed herbicide comprises the following steps successively:

[0029] Step 1: Dissolve the dispersant and emulsifier in water and mix well.

[0030] Step 2: dissolving fenmetrione in the mixed solution, and sand-milling to obtain aqueous solution I.

[0031] Step 3: Mix the thickener and ethofurazone, add preservative and grind to obtain solution II.

[0032] Step 4: Mix and feed the aqueous solution I and solution II, and grind repeatedly. The antifreeze and defoam...

Abstract

The invention discloses a mixed herbicide composition for beet field and a preparation method thereof. The herbicide composition comprises the active components of metamitron and ethofumesate with theweight percentage of 3.7880-8.6481:1. The herbicide composition is applied to weeding in the beet field, and the synergistic effect is obvious compared with a general single agent, the application times can be reduced, the safety of the beet field can be improved, the residual threat can be reduced, and the pollution to the environment can be reduced. The combination of two herbicides with different action mechanisms can reduce the development of drug resistance. The composition is highly effective and safe for beet fields, and is moderately priced.

Description

technical field [0001] The invention relates to a herbicide composition used in sugar beet fields, which can effectively control annual broad-leaved weeds in sugar beet fields at one time. Background technique [0002] Sugar beet is a high economically valuable and versatile crop that is the main source of sugar other than sugar cane. The crop is widely cultivated with great variation. Sugar beet is the most important commercial type, fodder beet and leaf beet are cultivated like most crops. [0003] The effect of herbicides in existing sugar beet fields is not ideal and needs to be further improved. Contents of the invention [0004] The object of the present invention is to provide a sugar beet field mixed herbicide composition containing fenmetrione and ethofurazone. The preparation adopts different weeding mechanisms, and has better control effect on older malignant weeds. [0005] The invention provides a mixed herbicide composition for sugar beet fields. The activ...
