Soybean weeding microemulsion and preparation method thereof

Abstract

The invention discloses a soybean weeding microemulsion and a preparation method thereof. The soybean weeding microemulsion is prepared from 10 to 30 parts of isopropylamine salt of glyphosate, 10 to 20 parts of sulfentrazone, 10 to 20 parts of emulgators of dioctyl sulfosuccinate sodium salt, 7 to 12 parts of glycerol, 7 to 15 parts of imazaquin, 10 to 20 parts of surface active agents, 5 to 12 parts of fulvic acid, 10 to 15 parts of chitin, 10 to 15 parts of haloxyfop-R-methyl, 5 to 10 parts of defoaming agents and 1 to 3 parts of preservatives. The soybean weeding microemulsion has the advantages that the preparation process is simple; the preparation process achieves the environment-friendly and pollution-free effects; the prepared soybean weeding microemulsion can be used for effectively clearing weed in soybeans without damaging the soybeans; residues cannot pollute soil or environment.

Description

technical field [0001] The invention relates to the technical field of preparation of herbicidal microemulsions, in particular to a soybean herbicidal microemulsion and a preparation method thereof. Background technique [0002] Soybean is commonly known as soybean, leguminous soybean is an annual herb, 30-90 cm high, the stem is thick, erect, densely covered with brown long bristles, the leaves usually have 3 leaflets; the stipules are veined and yellow pubescent; the petiole is 2- 20 cm; leaflets broadly ovate, papery; short racemes with few flowers, long ones with many flowers; total pedicels usually have 5-8 sessile, tightly squeezed flowers; bracts lanceolate, strigose ; bracteoles lanceolate, covered with setae; calyx lanceolate, flowers purple, lavender or white, base with petal stalk, wing petals castate, pod hypertrophy, slightly curved, drooping, yellow-green, densely covered with brown Yellow long hair; 2-5 seeds, oval, nearly spherical, smooth seed coat, light g...

[0002] Soybean is commonly known as soybean, leguminous soybean is an annual herb, 30-90 cm high, the stem is thick, erect, densely covered with brown long bristles, the leaves usually have 3 leaflets; the stipules are veined and yellow pubescent; the petiole is 2- 20 cm; leaflets broadly ovate, papery; short racemes with few flowers, long ones with many flowers; total pedicels usually have 5-8 sessile, tightly squeezed flowers; bracts lanceolate, strigose ; bracteoles lanceolate, covered with setae; calyx lanceolate, flowers purple, lavender or white, base with petal stalk, wing petals castate, pod hypertrophy, slightly curved, drooping, yellow-green, densely covered with brown Yellow long hair; 2-5 seeds, oval, nearly spherical, smooth seed coat, light green, yellow, brown and black, etc., flowering period June-July, fruit period July-September, used for existing soybean fields Although herbicides can remove weeds to a certain extent, they harm soybeans while removing weeds, and their residues will affect the soil and the environment. In addition, their removal effect is poor and the removal is not complete
