preparation example Construction

[0028] see figure 1 , a kind of method of the dispersible oil suspension containing glufosinate-ammonium, oxyflufen and high-efficiency haloxyfop of the present invention, the preparation method comprises the following steps:

[0029] In the first step, the emulsifier, dispersant, glufosinate-ammonium, acifluorfen and beta-haloxyfop are ground to a particle size of less than 0.01cm;

[0030]In the second step, add the component particles with a particle size below 0.01cm into the reactor, heat to 30-80°C, stir and mix, and disperse evenly;

[0031] The third step is to add a thickener under high-speed shearing, cool and crystallize, and then grind to a particle size below 5 μm;

[0032] In the fourth step, the prepared particles containing glufosinate-ammonium, fluorfen-carboxyfen, and haloxyfop-pam with a particle size of less than 5 μm, together with a stabilizer and vegetable oil, are added into the reaction kettle, mixed and dispersed evenly;

[0033] In the fifth step, ...

Abstract

The invention discloses dispersible oil suspending agent containing glufosinate ammonium, fluoroglycofen and haloxyfop-r-methyl and a preparation method of the dispersible oil suspending agent, belonging to the technical field of pesticides. The dispersible oil suspending agent contains glufosinate ammonium, fluoroglycofen and haloxyfop-r-methyl in a mass ratio of (1%-50%) to (1%-20%) to (1%-20%). The preparation method comprises the following steps: firstly grinding an emulsifying agent, a dispersing agent, glufosinate ammonium, fluoroglycofen and haloxyfop-r-methyl into powder with particle sizes of less than 0.01cm, adding the powder into a reaction kettle, heating, and uniformly mixing and dispersing; adding a thickening agent under a high-speed shear condition, grinding the mixture into powder with a particle size of less than 5 microns, adding a stabilizer, vegetable oil and deionized water into the reaction kettle, and uniformly dispersing and mixing, so as to obtain the dispersible oil suspending agent containing glufosinate ammonium, fluoroglycofen and haloxyfop-r-methyl. The dispersible oil suspending agent containing glufosinate ammonium, fluoroglycofen and haloxyfop-r-methyl has a remarkable synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a dispersible oil suspension containing glufosinate-ammonium, acifluorfen and high-efficiency haloxyfop and a preparation method thereof. The dispersible oil suspension concentrate is used for weeding in non-arable land. Background technique [0002] Weeds in non-cultivated land mainly include weeds in woodlands, lawns, roads, railways, warehouses, field ridges, ditches, and beside forest fire escapes. When weeds occur, the grass phase is complex, the emergence is uneven, grass weeds, broad-leaved weeds, sedges and other types of weeds are mixed, such as dandelion, plantain, Prunella vulgaris, wild amaranth, bracken, four-leaf Lotus, calla, stinky peony, crossing river vine, night cross vine (polygonum multiflorum), wild motherwort, crabgrass, barnyardgrass, daughter of a thousand golds, sagegrass, sagetail, goosegrass, bluegrass, wild oats, Phragmites, imperata, bermudagras...
