Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a multi-element mixed composition water dispersible granule.
Background
Pesticides are one of important agricultural production materials, and modern agriculture cannot be separated from pesticides. Weeds are easy to compete for moisture, nutrients, soil and space with crops due to vigorous vitality of the weeds, are hosts of crop diseases and insect pests, spread the diseases and insect pests, degrade the yield and quality of the crops, increase the harmfulness, and increase the labor for management and the production cost; with the acceleration of the urbanization process in China, a great amount of rural labor is transferred to cities, the rural high-quality labor is seriously insufficient, and compared with an insecticide and a bactericide, the herbicide is used for selectively preventing and removing weeds between crops and the weeds.
The glufosinate-ammonium belongs to a biocidal contact type herbicide, has good killing activity on most uncultivated land weeds, has the advantages of wide weed control spectrum, low toxicity, high activity, good partial conductivity, good environmental compatibility and the like, but has weak systemic property and quick action. Flumioxazin is a contact type selective herbicide, and after the surface layer of soil is treated by the flumioxazin, a medicament is absorbed by soil ions to form a treatment layer on the surface of the soil, and when weeds germinate, seedlings are withered by contacting the medicament treatment layer. When the stem leaves are treated, the water can be absorbed by young teeth and leaves of plants, and is conducted in plant bodies, so that the water acts on the leaf surfaces of sensitive weeds quickly, protoporphyrin accumulation is caused, the lipid peroxidation of cell membranes is enhanced, and the irreversible damage to the cell membrane structures and cell functions of the sensitive weeds is caused. The fluoroglycofen-ethyl is a diphenyl ether herbicide, can greatly increase the permeability of glufosinate-ammonium, is quickly absorbed by weed stems and leaves, ammonium ions quickly accumulate in the stems and leaves to reach a threshold value and are conducted to roots, so that the ammonium ions at the roots of the weeds are poisoned and killed, the weeds are killed more quickly, and the weeds are weeding more thoroughly.
Because the current farmer non-cultivated land herbicide in China has less scientific application, a single-dose herbicide is usually applicable to one or limited concentrated weed species, the application range is narrower, the single-dose herbicide is easy to cause the resistance of weeds in the using process, the service life of the pesticide is reduced, the weeding effect is greatly reduced, but the pollution damage to the environment is not reduced.
