preparation example Construction

[0036] The present invention also provides that the herbicide composition can be made into an aqueous solution, and its preparation method specifically includes the following steps:

[0037] 1) Weigh water in proportion, dissolve the dye in the water, then add glufosinate-ammonium, and stir until completely dissolved;

[0038] 2) Add a certain amount of glyphosate salt and stir to mix;

[0039] 3) Finally add emulsifier and stir for 20-40 minutes.

[0040] The prepared herbicide composition was sampled and analyzed. The active ingredients are based on the national standards of the corresponding ingredients, such as: glyphosate water solution GB 20684-200, the pH value is measured according to GB / T 1601 cold storage stability is measured according to GB / T 19137 hot storage stability is measured according to GB / T 19136, the control The indicators are shown in Table 1.

[0047] The herbicide composition water formulation was prepared according to the formula ratio of the above-mentioned Examples 1-5, which was used for spraying on nursery trails and under large trees in gardens, and was suitable for the treatment of weeds in non-cultivated land. Among them, the herbicide compositions of Examples 1 to 5 can kill more than 40 families and more than 100 kinds of weeds, and can kill grasses and roots in the control of woodland imperatum, five-jointed awn, big awn, and vegetable fern; including the part of glyphosate Resistant weeds such as: goosegrass, bluegrass, sedge, bermudagrass, barnyardgrass, ryegrass, bentgrass, rice sedge, heterosedge, crabgrass, wild licorice, false Stinky grass, corn grass, rough-leaved grass, flying grass, wild amaranth, apricot, hollow lotus grass (revolutionary grass), chickweed, small fly, mother-in-law, purslane, brachiaria, corydalis , Convolvulus, Polygonum, Shepherd's Purse, Endive, Plantain, Buttercu...

Abstract

The invention discloses a weedicide composition and a preparation method thereof, wherein the weedicide composition comprises the following components in percentage by weight: 1-50% of glyphosate and 0.1-50% of glufosinate-ammonium. The weedicide composition disclosed by the invention has the advantages that the glufosinate-ammonium can be compounded with the glyphosate, and the glufosinate-ammonium has no negative effect on the using effect of the glyphosate, so that the resistance problem of the single glufosinate is solved, the using cost of the glufosinate-ammonium is also effectively reduced, meanwhile, the weeding speed of the glufosinate is accelerated, and the using effect of a glufosinate product is also enhanced.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a herbicide composition and a preparation method thereof. Background technique [0002] The Food and Agriculture Organization of the United Nations reported that there are about 50,000 species of weeds in the world, about 8,000 species of weeds in farmland, and about 250 species that harm the main food crops, of which 76 species are relatively serious, and 18 species are malignant weeds that are extremely harmful. According to statistics in 1972, crop yield loss caused by weed damage is 20.4 billion U.S. dollars every year in the world. [0003] Glyphosate is a broad-spectrum destructive and conductive herbicide developed by Monsanto in the 1970s. The widespread application of glyphosate and paraquat has promoted the promotion and development of no-tillage and low-tillage technologies around the world. Among them, paraquat products have been restricted or even banned due to their stro...
