Embodiment 1

[0027] A special herbicide for nursery, made of the following raw materials in parts by weight: 15 parts of glyphosate, 2 parts of trifluralin, 1 part of imazethapyr, 0.1 part of metsulfuron-methyl, 1 part of fungicide, 3 parts of auxiliary agent, 80 parts of water;

[0028] The glyphosate is 41% water glyphosate; the trifluralin is 480g / L EC trifluralin; the imazethapyr is 70% of the particles; the metsulfuron-methyl is 60% of the particles; The fungicide is obtained by water extraction of traditional Chinese medicines in the following weight proportions. The weight ratio of garlic: veratrum: aconitum roundleaf: white moss: elderberry: ailanthus: pokeweed is 10:2:2:2:2 :5:10. Add 3 times of water to the above traditional Chinese medicine, put it in a container and decoct for 1 hour, pour out the filtrate, add 2 times of water and decoct for 0.5 hour, pour out the filtrate again, combine the two times of filtrate, and dry under reduced pressure to obtain a relative density of...

Abstract

The invention discloses a special herbicide used in a nursery garden and a preparation method thereof, and belongs to the technical field of pesticides. The herbicide is prepared from the following raw materials in parts by weight: 15 parts of glyphosate, 2 parts of trifluralin, 1 part of imazethapyr, 0.1 part of metsulfuron-methyl, 1 part of a bactericide, 3 parts of auxiliaries and 80 parts of water, wherein the glyphosate is 41% water-based glyphosate, the trifluralin is 480g / L emulsifiable concentrate trifluralin, the imazethapyr is 70% particles and the metsulfuron-methyl is 60% particles; the bactericide is prepared by performing water extraction on garlic, veratrum nigrum, aconitum rotundifolium, fraxinella, elderberry, ailanthus and pokeberry root in a weight ratio of 10 to 2 to 2 to 2 to 2 to 5 to 10. The weeding active ingredients are combined for completely preventing the growth of weeds when being applied to seedling in the nursery garden, and meanwhile, plants cannot be influenced. The traditional Chinese medicine bactericide is added to the special herbicide, so that the incidence of soil-borne diseases and various root rot can be obviously reduced during weeding.

Description

technical field [0001] The invention relates to a special herbicide for nursery and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] In agricultural planting, dicotyledonous crops are planted after applying herbicides against dicotyledonous weeds in the field. During plant growth, the herbicides can be absorbed by the roots and leaves of the planted crops and conducted in the body. Rapidly inhibit the growth of plant roots and shoot tops, and the plants die within 3-14 days. Planting di / monocot crops 2-3 months after normal application of herbicides against di / monocotyledonous weeds will still cause phytotoxicity. [0003] Glyphosate is a systemic chronic broad-spectrum herbicide that mainly inhibits enolacetonyl shikimelin phosphate synthase in the body, thereby inhibiting the conversion of shikime to phenylalanine, tyrosine and tryptophan. Transformation, which interferes with protein synthesis leading to plant d...
