Problems solved by technology

[0003] So people began to prepare a variety of herbicides by compounding flufenazim with other components, but there are not many herbicides for soybean fields with simple ingredients, high efficiency, low toxicity, low residue, and easy degradation.

Embodiment 1

[0037] The composition and weight ratio when a kind of herbicide special for soybean field of the present invention is wettable powder are as follows:

[0038]

[0039] The preparation method is:

[0040] In turn, add the original drug, additives, fillers, etc. into the mixer and mix well, start the jet mill, grind the preparation mixture, and pass the inspection, and then you can prepare 80% fluramid propargyl wettable powder .

[0041] The composition of the invention is mainly used for weeds in soybean fields. When used as a wettable powder, it is diluted with water by 3000-7500 times according to the dose of the original drug 4-6 g / mu, stirred evenly, and used before soybean sowing.

[0042] The test results show that the 667m 2 Under the condition of applying 6 g (original drug) of 80% fluvafen propargyl wettable powder, it has a good control effect on weeds in soybean fields, and the control effect reaches 91.5% 7 days after application.

Embodiment 2

[0044] When a kind of special herbicide for soybean field of the present invention is water dispersible granule, the components and weight percent are as follows:

[0045]

[0046] The preparation method is: put the measured original drug and additives into the mixing kettle, stir evenly at room temperature, ultrafinely pulverize the material through the jet mill unit, transfer to the granulation mixer after mixing evenly, add deionized water evenly, After the material is stirred evenly, it is granulated, and when the moisture content is reached after drying, all indicators are checked to be qualified, and then the 50% fluorenfen propargyl water-dispersible granule can be prepared.

[0047] The composition of the invention is mainly used for weeds in soybean fields. When used as a water-dispersible granule, it is diluted with water by 3000-7500 times according to the dose of the original drug at 4-6 g / mu, stirred evenly, and used before soybean sowing.

[0048] The test res...

Embodiment 3

[0050] When a kind of special herbicide for soybean field of the present invention is a wettable powder, the components and weight percentages are as follows:

[0051]

[0052] The percentage by weight of the flufenazine of the present embodiment is 10%, the percentage by weight of the wetting agent is 5%, the percentage by weight of the dispersant is 9%, the percentage by weight of the defoamer is 1.1%, and the percentage by weight of the carrier is 74.9%.

[0053] The test results show that it has a good control effect on weeds in soybean fields, and the control effect reaches 95.9% 7 days after application.

Abstract

The invention relates to a herbicide special for a soybean field.The herbicide is prepared from, by weight, 10-90 parts of flumioxazin, 1-10 parts of wetting agent, 1-10 parts of dispersing agent and 1-88 parts of carrier.The ingredients are simple, and the herbicide has the advantages of being efficient, low in toxicity, low in residue level, high in activity, low in dosage and the like.The herbicide can be degraded easily in the environment and is safe to afterreap crops, the frequency of application is reduced, and cost is reduced.As a low-toxicity fluorine-containing pesticide, the herbicide can be absorbed by buds and blades of a plant to be transmitted in the body of the plant, so that synthesis of chlorophyll is inhibited, withering, whitening, necrosis and death of sensitive weeds can be achieved quickly, and annual broadleaved weeds and part of grassy weeds in the field of soybean, peanut and orchard are effectively controlled.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a special herbicide for soybean fields. Background technique [0002] There are many kinds of weeds in soybean fields, and there are also many kinds of herbicides. As a kind of N-phenylphthalimide herbicide (contact type selective herbicide) created and developed by Sumitomo Chemical Industry Co., Ltd. of Japan, flufenazim can inhibit protoporphyrinogen oxidase, It can lead to photosensitization and peroxidation of cell membrane lipids, causing irreversible damage to cell membrane tenderness and organization. Stems and leaves of sensitive weeds were necrotic after stem and leaf treatment, and died after sun exposure, and sensitive weed buds were necrotic after soil treatment, and died after short-term sun exposure. [0003] So people began to prepare various herbicides by compounding flufenazim with other components, but there are not many herbicides for soybean fields with simple ing...
