Problems solved by technology

Glyphosate in the form of free acid has low solubility in water. Therefore, commercial preparations contain water-soluble salts of glyphosate, glyphosate soluble solid preparations, and there is no oil suspension in the form of glyphosate free acid in the market
Currently used for weed control in orchards, tea gardens, economic woodlands, field ridges, wide-row crops, etc., such as single glyphosate, Kewuzong, etc. are all weed seedling treatment agents, which are limited to germinating weeds. Grass has a contact killing effect and is passivated when it meets the soil. It has no control effect on the weed seeds that have not germinated in the soil when the pesticide is applied, and the damage can still be reproduced afterwards, and the cost per mu is relatively high when used

Embodiment Construction

[0039] The technical solution of the present invention will be further specifically described below through specific examples.

[0040] The formula table of table one embodiment 1-7 killing property herbicide

[0041]

[0042] As shown in Table 1, the active ingredient of Example 5 is 40% herbicide, which contains 30 g of 98% glyphosate, 8.0 g of 95% oxyfluorfen, and surfactant TX-104.4 g. Surfactant 500# calcium salt series 4.6g, organic bentonite BK-8880.14g, and the rest is corn oil. The amount per mu is 200-250g, mixed with 45 kilograms of water, sprayed with a knapsack sprayer, and the control situation of various grasses after 7 days is compared with the use of 41% glyphosate isopropylamine saline solution, 40% glyphosate soluble powder and blank The comparison of the sample time and the effect are shown in Table 2. As can be seen from Table 2, the control effect of this total herbicide on listed various grasses is 67-100%, as can be seen in addition, the control effe...

Abstract

The invention relates to a pesticide and a preparation method thereof, in particular to an unselective herbicide and a preparation method thereof. The unselective herbicide is characterized by being an oil suspending agent prepared by mixing glyphosate, oxyfluorfen and auxiliary materials. In the invention, the glyphosate and the oxyfluorfen are combined, the oxyfluorfen has the touch killing action on the blades of a plant so as to accelerate the absorption of the glyphosate and enhance the pesticide effect of the glyphosate, and the oxyfluorfen has the certain inhibiting effect on weed seeds in the soil so as to prolong the residual life. The herbicide has the advantages of excellent performances on weeding speed, environmental friendliness and herbicide cost conservation as well as obvious effect, wide weeding spectrum, long pesticide effect, rain washing resistance, environmental friendliness and the like on the weeding effect.

Description

(1) Technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a total herbicide and a preparation method thereof. (2) Background technology [0002] Glyphosate (Glyphosate), whose chemical name is N-phosphonomethylglycine, is a systemic conduction type chronic broad-spectrum herbicide that mainly inhibits enolacetonyl shikimelin phosphate synthase in the body, thereby inhibiting the development of shikimicin. The conversion of phenylalanine, tyrosine, and tryptophan interferes with protein synthesis and causes plant death. Glyphosate is absorbed by the stems and leaves and then transmitted to various parts of the plant. It can control more than 40 families of plants such as monocots and dicotyledons, annuals and perennials, herbs and shrubs. After entering the soil, glyphosate quickly combines with metal ions such as iron and aluminum to lose its activity. It has no adverse effects on the seeds and soil microorganisms hid...
