Anilofos-containing herbicide, preparation method and application thereof

Abstract

The invention discloses an anilofos-containing herbicide as well as a preparation method and application thereof, and belongs to the technical field of herbicides, the preparation method comprises the following steps: preparing an inner core substance, wrapping the inner core, preparing an outer herbicide, and preparing the anilofos-containing herbicide. The preparation of the inner core substance comprises the following steps: uniformly mixing a difenoconazole active compound, a thiram active compound, sodium dodecyl sulfate, lauryl sodium sulfate, polyethylene glycol 4000, vesuvianite powder and zwitter-ion polyacrylamide to obtain a raw material mixture, and then putting the raw material mixture into a liquid nitrogen ball milling tank for liquid nitrogen ball milling to obtain the inner core substance; the prepared anilofos-containing herbicide can reduce the phytotoxicity when the anilofos-containing herbicide is used, the compounding effect is improved, meanwhile, the prepared anilofos-containing herbicide further has the bactericidal performance, and breeding and growth of bacteria can be reduced when the anilofos-containing herbicide is used.

Description

technical field [0001] The invention relates to a herbicide containing saponin, a preparation method and application thereof, and belongs to the technical field of herbicides. Background technique [0002] Phosphorus is an organophosphorus selective systemic herbicide, which is absorbed through the young shoots and underground stems of plants, inhibits cell fission and extension, makes it difficult for weeds to pull out new leaves, stops growth, and finally dies. Best results; less effective on established weeds. The growth of weeds stops after receiving the medicine, the leaves are dark green, sometimes decolorized, the leaves become shorter and thicker, and they are easy to break, the heart leaves are not easy to pull out, and finally the whole plant dies. , although the control effect is good, the control range is limited, and it can only control barnyardgrass and sedge weeds in the three-leaf period, and the control effect on older weeds is poor. [0003] In order to e...

Problems solved by technology

, although the control effect is good, but the control range is limited, and it can only control barnyardgrass and sedge weeds in the three-leaf stage, and the control effect on older weeds is poor

[0003] In order to expand the control range of saponin, a compound method is usually used to mix sabaphos with other herbicides or insecticides, so as to expand the herbicide spectrum, reduce the dosage of pesticides, reduce production costs, reduce pesticide residues, and improve It is safe for crops, but when mixed with other herbicides, improper compounding is likely to cause phytotoxicity and affect the use effect, and the compounding technology is immature now, and when more than two kinds of pesticides are compounded, it is easy to affect the compounding effect; in addition, when using saponin, it will increase the resistance of bacteria to antibiotics, thereby causing the increase of bacteria, but sabaphos cannot be used in combination with fungicides, so when using sabaphos, it will cause bacteria mass reproduction and growth

[0004] Patent CN109769852A discloses a herbicide composition containing sabaphos, cyhalofop-methyl and bicyclic sulcotrione. The herbicide composition has a synergistic effect, wherein the active ingredient in the herbicide composition is The mass ratio of saponin, cyhalofop-ethyl and bicyclic sulcotrione is 1-50:1-30:5-25, more preferably 1-25:5-30:5-25, most It is preferably 10-25:5-30:5-20; the deficiency of this patent: when this herbicide composition is used, can increase the tolerance of bacteria to antibiotics, thereby cause the increase of bacteria
